Grammar and Sentence Structure Practice Test 2 Flashcards

Choose the sentence that is grammatically correct.

Answer: She doesn't know the answer to the question.

With a third-person singular subject ('she'), the auxiliary verb must be 'doesn't' (does + not), and the main verb stays in its base form 'know' — not 'knows'.

Fill in the blank: 'He _____ to school every day when he was young.'

Answer: walked

The phrase 'when he was young' signals a past habitual action, so the simple past tense 'walked' is correct.

Which sentence uses articles correctly?

Answer: They adopted a dog from an animal shelter.

'A' is used before consonant sounds and 'an' before vowel sounds. 'A dog' is correct (consonant sound), and 'an animal shelter' is correct (vowel sound).

Choose the correct pronoun to complete the sentence: 'The teacher gave _____ the assignment yesterday.'

Answer: us

After a verb like 'gave', an object pronoun is needed. 'Us' is the object form of 'we', while 'we' is a subject pronoun and cannot be used here.

Which sentence correctly uses a conjunction to join two ideas?

Answer: She was tired, but she finished her homework.

A comma is placed before a coordinating conjunction ('but') when it joins two independent clauses. No additional comma is needed after 'but'.

Fill in the blank: 'By the time class started, the teacher _____ already written the instructions on the board.'

Answer: had

The past perfect tense ('had' + past participle) is used to show that one past action was completed before another past action. 'Had written' is correct here.
