Gaokao - National College Entrance Exam — Questions and Answers

Question 1: The reaction rate of A + B → products is found experimentally to double when [A] doubles (B constant) and quadruple when [B] doubles (A constant). The rate law is:

rate = k[A][B]
rate = k[A][B]² (Correct answer)
rate = k[A]²[B]²
rate = k[A]²[B]

Correct answer: rate = k[A][B]²

Rate doubles with [A] → first order in A; rate quadruples with [B] → second order in B. Rate = k[A][B]².

Question 2: I used to be a person who was afraid of public speaking. The mere thought of standing before an audience would make my palms sweat and my heart 1. This fear held me back in many ways, both in school and in my personal life. I knew I had to 2 it. My opportunity came when our English teacher announced a speech contest. 3 everyone else was excited, I was terrified. However, a friend encouraged me, saying, 'The only way to get over a fear is to face it.' His words 4 with me. I decided to participate. I spent weeks preparing, practicing in front of a mirror, and then in front of my family. On the day of the contest, I was still nervous, but as I walked onto the stage, I took a deep breath and remembered my friend's advice. I started speaking, and to my 5, the words flowed smoothly. When I finished, the audience applauded. That moment was a turning point. I didn't win the contest, but I won something more 6: confidence.

4. stuck (Correct answer)
4. agreed
4. played
4. argued

Correct answer: 4. stuck

The idiom 'stuck with me' means that the narrator remembered the words and they had a lasting effect. The friend's advice was memorable and influential.

Question 3: In a cube with edge length 2, what is the distance from the center of the cube to a vertex?

2
√2
√3 (Correct answer)
2√3

Correct answer: √3

The space diagonal of a cube with edge a = 2 has length 2√3. The center is halfway along the space diagonal, so the distance from center to vertex = √3.

Question 4: The 'Coriolis effect' causes winds in the Northern Hemisphere to deflect:

To the left of their direction of motion
To the right of their direction of motion (Correct answer)
Vertically upward from the surface
Directly toward the equator

Correct answer: To the right of their direction of motion

Earth's rotation causes moving air (and water) to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, creating the characteristic spiral patterns of cyclones and anticyclones.

Question 5: Read the passage and answer the question. Passage: Traditional festivals play a vital role in preserving cultural identity. They provide occasions for communities to come together, passing on customs, foods, music, and stories from one generation to the next. As globalization promotes cultural homogeneity, many local festivals face declining participation. Cultural experts argue that losing these traditions represents an irreversible erosion of human diversity. The phrase 'cultural homogeneity' most likely means:

Cultural exchange between neighboring countries.
The revival of traditional customs in modern cities.
A wide variety of cultural practices across the world.
A single dominant culture replacing diverse local cultures. (Correct answer)

Correct answer: A single dominant culture replacing diverse local cultures.

Homogeneity means sameness; in context, it contrasts with the diversity of local traditions being lost, suggesting one uniform culture.

Question 6: Which of the following is a push factor causing international migration?

Political persecution or war in the country of origin (Correct answer)
Higher wages available in the destination country
Family reunification policies in the destination country
Better educational opportunities in the receiving country

Correct answer: Political persecution or war in the country of origin

Push factors drive people away from their origin country; political persecution, conflict, famine, and natural disasters are classic push factors, while higher wages and better education are pull factors.

Question 7: What alternative options are available for students who do not meet university cut-off scores?

Enrolling in vocational colleges. (Correct answer)
Retaking the Gaokao the following year. (Correct answer)
Changing their chosen major within the same university.
Applying to universities abroad that accept Gaokao scores. (Correct answer)

Correct answer: Enrolling in vocational colleges.

For students who do not achieve the required Gaokao scores for university admission, retaking the exam the following year is a very common alternative. Many dedicate another year to intensive study to improve their scores and secure a place in their desired university. Other options include vocational colleges or studying abroad, but retaking is a direct path to re-entry into the university application system.

Question 8: Which molecule carries amino acids to the ribosome during translation?

rRNA
mRNA
tRNA (Correct answer)
snRNA

Correct answer: tRNA

Transfer RNA (tRNA) molecules have anticodons that recognize mRNA codons and carry the corresponding amino acid to the ribosome.

Question 9: The Shanghai Massacre (四一二政变) of April 12, 1927 was a turning point in Chinese history because it:

Ended the cooperation between the Soviet Union and Chiang Kai-shek's government
Prompted the Soviet Union to send military aid directly to the Communist Party
Forced Japan to withdraw its forces from Shanghai's International Settlement
Shattered the First United Front as Chiang Kai-shek violently purged Communist allies (Correct answer)

Correct answer: Shattered the First United Front as Chiang Kai-shek violently purged Communist allies

On April 12, 1927, Chiang Kai-shek ordered Nationalist forces and Shanghai underworld gangsters to massacre Communist Party members and labor unionists, killing thousands. This ended the First United Front and launched an open civil war between the KMT and CCP.

Question 10: The 'Rostow stages of economic development' model predicts that all societies pass through how many distinct stages?

Five (Correct answer)
Four
Three
Seven

Correct answer: Five

Rostow's 1960 model identifies five stages: traditional society, preconditions for take-off, take-off, drive to maturity, and the age of high mass consumption.

Question 11: The United Nations Security Council has five permanent members (P5) with veto power. Which of the following is the correct list of P5 members?

USA, Russia, China, Germany, Japan
USA, Russia, UK, Germany, Brazil
USA, Russia, China, UK, France (Correct answer)
USA, China, UK, India, France

Correct answer: USA, Russia, China, UK, France

The five permanent members of the UN Security Council are the United States, Russia (successor to Soviet Union), China (represented by the PRC since 1971), the United Kingdom, and France — all major WWII Allied powers.

Question 12: A satellite orbits Earth at radius R with period T. If it moves to orbit at radius 4R, what is its new period?

2T
4T
16T
8T (Correct answer)

Correct answer: 8T

Kepler's Third Law: T² ∝ R³. If R increases by factor 4, then T² increases by factor 4³ = 64, so T increases by factor 8. New period = 8T.

Question 13: The SI unit of inductance is the Henry (H). 1 H is equivalent to:

1 Ω·s
1 V·s/A
All of the above are equivalent (Correct answer)
1 T·m²/A

Correct answer: All of the above are equivalent

1 H = 1 V·s/A (from EMF = L dI/dt) = 1 T·m²/A (from flux linkage) = 1 Ω·s; all three expressions are dimensionally equivalent.

Question 14: The line y = kx + 1 intersects the parabola y² = 4x at exactly one point. What is the value of k (where k ≠ 0)?

k = 2
k = 1 (Correct answer)
k = 1/2
k = -1

Correct answer: k = 1

Substitute the line equation into the parabola equation: (kx + 1)² = 4x. This expands to k²x² + 2kx + 1 = 4x, or k²x² + (2k - 4)x + 1 = 0. For the line to be tangent (intersect at one point), the discriminant (Δ) of this quadratic equation must be zero. Δ = b² - 4ac = (2k - 4)² - 4(k²)(1) = 0. Expanding this gives 4k² - 16k + 16 - 4k² = 0, which simplifies to -16k + 16 = 0, so k = 1.

Question 15: Read the passage and answer the question. Passage: Nuclear energy provides about 10% of the world's electricity. Unlike fossil fuels, it emits almost no greenhouse gases during operation. However, it carries significant risks: accidents at Chernobyl and Fukushima demonstrated the potential for catastrophic failure. The problem of long-term radioactive waste disposal remains unsolved. Despite these drawbacks, some environmentalists argue that nuclear energy must play a role in combating climate change because renewable sources alone may not provide enough power quickly enough. Why do some environmentalists support nuclear energy despite its risks?

Because nuclear accidents are now entirely preventable with modern technology.
Because nuclear energy is cheaper than all other energy sources.
Because nuclear energy produces no waste of any kind.
Because renewables alone may not decarbonize the energy supply fast enough. (Correct answer)

Correct answer: Because renewables alone may not decarbonize the energy supply fast enough.

The passage says some environmentalists support nuclear because renewables alone may not provide sufficient power quickly enough to address climate change.

Question 16: A regular tetrahedron has edge length 2. What is its volume?

2√2/3 (Correct answer)
8√3/3
4√3/3
√2/3

Correct answer: 2√2/3

The volume of a regular tetrahedron with edge length a is V = a³√2/12. Substituting a = 2: V = 8√2/12 = 2√2/3.

Question 17: Which statement correctly describes Le Chatelier's principle?

Catalysts shift the equilibrium position
A system shifts to fully eliminate any imposed stress
A system at equilibrium shifts to partially offset any imposed stress (Correct answer)
Equilibrium constants change with all applied stresses

Correct answer: A system at equilibrium shifts to partially offset any imposed stress

Le Chatelier's principle states the system partially counteracts the imposed change; it does not fully reverse it, and K only changes with temperature.

Question 18: In Mendel's Law of Independent Assortment, genes on different chromosomes are inherited:

Only from the mother
In a fixed ratio of 2:1
Together, always linked
Independently of each other (Correct answer)

Correct answer: Independently of each other

Genes located on non-homologous chromosomes segregate independently during meiosis, producing varied combinations in offspring.

Question 19: In classical Chinese, the pattern '虽…然…' typically means:

If… then…
Either… or…
Although… nevertheless… (Correct answer)
Because… therefore…

Correct answer: Although… nevertheless…

'虽' (suī) means 'although/even though' and '然' (rán) here means 'but/nevertheless,' forming a concessive pattern: 'Although X, nevertheless Y.'

Question 20: Read the passage and answer the question. Passage: E-books and digital reading devices have transformed how people consume written material. Proponents point to convenience: a single device can store thousands of books. Studies suggest, however, that readers retain information more effectively when reading print. Researchers theorize this may be because physical page-turning provides spatial cues that help readers navigate and remember content. What reason do researchers give for better retention with print?

Print books have larger fonts that are easier to read.
Readers spend more time reading print books than digital ones.
Physical page-turning provides spatial cues that aid memory. (Correct answer)
Print books contain more detailed information than e-books.

Correct answer: Physical page-turning provides spatial cues that aid memory.

The passage directly attributes better retention to spatial cues provided by physical page-turning.

Question 21: Which reagent can be used in the laboratory to distinguish an alkene from an alkane?

Bromine water (Br₂/H₂O) (Correct answer)
Dilute hydrochloric acid (HCl)
Aqueous sodium hydroxide (NaOH)
Anhydrous sodium sulfate (Na₂SO₄)

Correct answer: Bromine water (Br₂/H₂O)

Alkenes rapidly decolorise bromine water through electrophilic addition across the C=C double bond, turning the orange-brown solution colourless. Alkanes do not react with bromine water under normal conditions and the colour is retained.

Question 22: The chord of contact of point P(2, 1) with respect to the circle x² + y² = 5 has equation:

x + 2y = 5
x - 2y = 5
2x + y = 5 (Correct answer)
2x - y = 5

Correct answer: 2x + y = 5

The chord of contact from external point (x₀, y₀) to circle x² + y² = r² is xx₀ + yy₀ = r². So: 2x + y = 5.

Question 23: For an endothermic reaction at equilibrium, increasing temperature will:

Leave K unchanged
Increase K and shift equilibrium toward reactants
Decrease K and shift equilibrium toward products
Increase K and shift equilibrium toward products (Correct answer)

Correct answer: Increase K and shift equilibrium toward products

For an endothermic reaction, heat is a 'reactant'; adding heat (increasing T) shifts equilibrium to the product side and increases K.

Question 24: Which type of cell division produces four haploid daughter cells genetically different from the parent cell?

Meiosis (Correct answer)
Amitosis
Binary fission
Mitosis

Correct answer: Meiosis

Meiosis undergoes two rounds of division (meiosis I and II) after one round of DNA replication, producing four genetically unique haploid cells (gametes or spores).

Question 25: The Nernst equation E = E° − (RT/nF)ln Q allows calculation of cell potential under non-standard conditions. At 25°C, RT/F ≈ 0.02569 V. For a two-electron process, E = E° when:

Q = K
Q = 0
E° = 0
Q = 1 (all concentrations at standard state) (Correct answer)

Correct answer: Q = 1 (all concentrations at standard state)

When Q = 1, ln Q = 0, so E = E°; this corresponds to all species at unit activity (standard state).

Question 26: Read the passage and answer the question. Passage: The Renaissance was a cultural movement that emerged in Italy during the 14th century and gradually spread across Europe. It was characterized by a renewed interest in the art, literature, and philosophy of ancient Greece and Rome. Renaissance thinkers championed humanism — the idea that human beings, rather than divine authority, are the center of intellectual and artistic inquiry. This shift had profound effects on science, philosophy, and the arts. According to the passage, what was 'humanism'?

The belief that humans, not divine authority, are the central focus of thought. (Correct answer)
A religious movement that replaced Christianity in Renaissance Europe.
A scientific theory developed during the Renaissance period.
The practice of translating ancient Greek texts into Latin.

Correct answer: The belief that humans, not divine authority, are the central focus of thought.

The passage explicitly defines humanism as placing human beings at the center of intellectual and artistic inquiry.

Question 27: Let f(x) = x² - 2|x| + 1. The minimum value of f(x) is:

2
-1
1
0 (Correct answer)

Correct answer: 0

For x ≥ 0: f(x) = x²-2x+1 = (x-1)²; minimum is 0 at x=1. For x < 0: f(x) = x²+2x+1 = (x+1)²; minimum is 0 at x=-1. Global minimum = 0.

Question 28: The 'induced fit' model of enzyme action states that:

Only substrates with exactly the right shape can bind to the active site
Enzymes are permanently altered after each catalytic reaction
Substrate binding is entirely random and non-specific
The active site changes shape to fit the substrate upon binding (Correct answer)

Correct answer: The active site changes shape to fit the substrate upon binding

In the induced fit model, substrate binding causes the enzyme's active site to change shape, forming a more complementary fit that stabilizes the transition state.

Question 29: A sphere is inscribed in a regular tetrahedron with edge length a. Which formula gives the radius of the inscribed sphere?

r = a/4
r = a/2
r = a√6/12 (Correct answer)
r = a√3/6

Correct answer: r = a√6/12

For a regular tetrahedron with edge a, the inradius r = a/(2√6) = a√6/12.

Question 30: The Hundred Days' Reform (百日维新, 1898) failed primarily because:

The reformers ran out of funding
Empress Dowager Cixi and conservative Qing officials launched a coup (戊戌政变) overthrowing the reformers (Correct answer)
The reform lacked popular support among ordinary Chinese
Western powers intervened to stop modernization

Correct answer: Empress Dowager Cixi and conservative Qing officials launched a coup (戊戌政变) overthrowing the reformers

After 103 days of reform edicts by Emperor Guangxu, Empress Dowager Cixi staged the Wuxu Coup (September 1898), arrested the Emperor, executed six leading reformers (戊戌六君子), and reversed most reforms.

Question 31: Electromagnetic induction was discovered experimentally by:

Michael Faraday (Correct answer)
Heinrich Hertz
James Clerk Maxwell
André-Marie Ampère

Correct answer: Michael Faraday

Faraday discovered electromagnetic induction in 1831 through experiments with changing magnetic flux.

Question 32: A negatively charged particle enters a magnetic field directed into the page moving to the right. The particle experiences a force directed:

Out of the page
Downward (Correct answer)
Into the page
Upward

Correct answer: Downward

F = qv × B; for negative charge moving right (v = +x̂) in field into the page (B = −ẑ): v × B = x̂ × (−ẑ) = +ŷ, then F = (−e)(+ŷ) = −ŷ, i.e. downward.

Question 33: Read the passage and answer the question. Passage: Language shapes how we perceive the world. The Sapir-Whorf hypothesis suggests that the structure of a language affects its speakers' cognition. A classic example involves color perception: researchers found that speakers of languages with more color terms could distinguish between similar shades more easily than speakers with fewer terms. While the strong version of this hypothesis — that language completely determines thought — is widely rejected, the idea that language influences perception retains scientific support. Which version of the Sapir-Whorf hypothesis does the passage say is rejected?

The version supported by research on color terms.
The idea that language influences color perception.
The strong version, which claims language completely determines thought. (Correct answer)
The weak version, which says language slightly affects thought.

Correct answer: The strong version, which claims language completely determines thought.

The passage says the 'strong version' — that language completely determines thought — is 'widely rejected.'

Question 34: In Gaokao essay scoring, which criterion is weighted most heavily?

Handwriting neatness
Content (内容) including the depth and clarity of the central argument (Correct answer)
Essay length
Number of literary quotations used

Correct answer: Content (内容) including the depth and clarity of the central argument

Gaokao essay grading prioritizes content (内容) — the quality, depth, and clarity of the central argument — as the most heavily weighted criterion. Language and structure are also important but secondary to having a strong, clear thesis.

Question 35: In the cloze passage, which word best fits: 'The new technology proved to be highly _____, saving the company both time and money in the long run.'

efficient (Correct answer)
dangerous
expensive
complicated

Correct answer: efficient

'Efficient' means achieving maximum productivity with minimum wasted effort, which directly explains how the technology saved time and money. The other options would not logically result in savings and benefits.

Question 36: The Zunyi Conference, held in January 1935 during the Long March, is considered a critical turning point for the Chinese Communist Party primarily because it:

Decided to end the Long March and settle in Yan'an.
Formally established the First United Front with the Kuomintang.
Established Mao Zedong's de facto leadership over the party and army. (Correct answer)
Marked the beginning of the Long March.

Correct answer: Established Mao Zedong's de facto leadership over the party and army.

At the Zunyi Conference, the party leadership critically assessed the military failures that had forced the Red Army on the Long March. The conference condemned the strategic errors of the previous leadership and resulted in the consolidation of Mao Zedong's leadership position within the party and military, fundamentally altering the course of the revolution.

Question 37: A frequency table shows scores: 60 (5 students), 70 (8 students), 80 (7 students), 90 (5 students). What is the mode?

90
80
70 (Correct answer)

Correct answer: 70

The mode is 70 because it appears most frequently (8 students).

Question 38: A cone has base radius r and slant height l. What is the lateral surface area?

πr²l
πr²
πrl (Correct answer)
2πrl

Correct answer: πrl

The lateral surface area of a cone is πrl, where r is the base radius and l is the slant height (斜高). This comes from unrolling the lateral surface into a sector of a circle.

Question 39: In an arithmetic sequence {aₙ}, if a₁ = 3 and the common difference d = 4, what is a₅?

19 (Correct answer)
16
15
17

Correct answer: 19

Using the formula aₙ = a₁ + (n−1)d, a₅ = 3 + (5−1)×4 = 3 + 16 = 19.

Question 40: The phrase '一本' (yī běn, First Tier) in Chinese university admissions refers to:

The first batch of universities in the traditional admission system, generally including key national universities with higher admission score cutoffs (Correct answer)
The top-ranked single university in China
First-year university students
The first subject on the Gaokao exam

Correct answer: The first batch of universities in the traditional admission system, generally including key national universities with higher admission score cutoffs

'一本' refers to the first admission batch (第一批次) in the traditional system, which included key national universities (211/985) with higher score thresholds. 二本 was the second batch with lower thresholds.

Question 41: The dihedral angle between two adjacent faces of a regular tetrahedron is approximately:

60°
arccos(1/3) ≈ 70.5° (Correct answer)
120°
90°

Correct answer: arccos(1/3) ≈ 70.5°

The dihedral angle of a regular tetrahedron is arccos(1/3) ≈ 70.53°. This can be derived by finding the angle between two face normal vectors.

Question 42: A regular pyramid has a square base with side 6 and four equilateral triangular lateral faces. What is the height of the pyramid?

3
3√2 (Correct answer)
√18
6

Correct answer: 3√2

Wait — if lateral faces are equilateral with side 6, the slant height = 6 (from apex to base edge midpoint? No — equilateral triangle side = base edge = 6, so lateral edge = 6). Height h = √(lateral edge² - (half diagonal)²) = √(36 - 18) = √18 = 3√2.

Question 43: Two charges +Q and −Q are separated by distance d. The electric potential at the midpoint between them is:

2kQ/d
kQ/(d/2)
−kQ/(d/2)
Zero (Correct answer)

Correct answer: Zero

Potential is a scalar; V = kQ/(d/2) + k(−Q)/(d/2) = 0.

Question 44: In a rectangular box (cuboid) with dimensions 3 × 4 × 12, what is the length of the space diagonal?

√169 = 13
13 (Correct answer)
√193
5

Correct answer: 13

Space diagonal d = √(3² + 4² + 12²) = √(9 + 16 + 144) = √169 = 13.

Question 45: ATP synthase in the mitochondria produces ATP using energy derived from:

Reduction of FAD to FADH₂
Direct transfer of phosphate groups from NADH
The proton gradient across the inner mitochondrial membrane (Correct answer)
Substrate-level phosphorylation in the matrix

Correct answer: The proton gradient across the inner mitochondrial membrane

H⁺ ions flow down their electrochemical gradient through ATP synthase (Complex V) from the intermembrane space to the matrix, driving ATP synthesis via chemiosmosis.

Question 46: The Marco Polo Bridge Incident (七七事变) of July 7, 1937 is historically significant because it:

Led to the formation of the First United Front between the CCP and KMT
Marked the beginning of Japan's full-scale invasion of China and the Second Sino-Japanese War (Correct answer)
Resulted in the Nationalist government relocating its capital from Nanjing to Wuhan
Triggered China's entry into World War I on the side of the Allied Powers

Correct answer: Marked the beginning of Japan's full-scale invasion of China and the Second Sino-Japanese War

The clash between Japanese and Chinese troops near Beijing on July 7, 1937 escalated into Japan's full-scale invasion, launching the Second Sino-Japanese War (1937–1945), also called the War of Resistance Against Japanese Aggression (抗日战争).

Question 47: How many points is the major composition (作文) section worth on the Gaokao Chinese language paper?

60 points (Correct answer)
50 points
40 points
30 points

Correct answer: 60 points

The Gaokao Chinese paper totals 150 points, and the major essay accounts for 60 of those points — making it the single highest-value item on the paper and a decisive factor in overall Chinese scores.

Question 48: China's Reform and Opening Up Policy (改革开放) launched in 1978 was initiated by:

Hua Guofeng as a continuation of previous policies
The National People's Congress independently
Mao Zedong before his death in 1976
Deng Xiaoping at the Third Plenary Session of the 11th Central Committee of the CPC (Correct answer)

Correct answer: Deng Xiaoping at the Third Plenary Session of the 11th Central Committee of the CPC

The Third Plenary Session of the 11th Central Committee (十一届三中全会, December 1978) marked Deng Xiaoping's rise and launched the reform era: shifting focus from class struggle to economic development.

Question 49: Read the passage and answer the question. Passage: Mangrove forests grow along tropical coastlines and provide a range of ecosystem services. Their tangled root systems trap sediment and reduce coastal erosion. They serve as nurseries for fish and other marine species. During storms, mangroves absorb wave energy, protecting inland communities. Despite their value, large areas of mangrove forest have been cleared for shrimp farming and coastal development. Which word best replaces 'nurseries' in context?

hospitals
schools
farms
shelters and breeding grounds (Correct answer)

Correct answer: shelters and breeding grounds

In ecological context, 'nurseries' refers to areas where young fish grow up, i.e., shelters and breeding grounds.

Question 50: Read the passage and answer the question. Passage: In the 19th century, women who pursued higher education faced tremendous obstacles. Many universities refused to admit female students. Those who did gain access were often barred from the same libraries, laboratories, and lectures as men. Despite this, pioneering women such as Marie Curie earned advanced degrees and made groundbreaking scientific contributions, challenging prevailing beliefs about women's intellectual capabilities. What does the author imply by describing Marie Curie and others as 'pioneering'?

They were exceptional individuals who overcame extraordinary barriers. (Correct answer)
They were the first women to reject education entirely.
They proved that all women in the 19th century were scientists.
They were supported by universities in their scientific work.

Correct answer: They were exceptional individuals who overcame extraordinary barriers.

'Pioneering' implies going first in difficult circumstances; the passage shows these women overcame significant systemic barriers.
