Read the sentence: 'Yesterday, I was watching a movie, but now I ______ my homework.' Which verb form correctly shifts the tense to the present progressive?

• did

• am doing

• will do

• had done

Answer explanation

The sentence shifts from a past action ('was watching') to a present action ('now'), so the present progressive tense 'am doing' is required to show an action happening at the moment of speaking.

In the sentence, 'By 2025, she will have graduated from college,' what is the tense of the verb phrase and what is its function?

• Future Perfect; it describes an action that will be completed before a specific time in the future.

• Simple Future; it describes an action that will happen in the future.

• Future Progressive; it describes an ongoing action in the future.

• Past Perfect; it describes an action completed before another past action.

Answer explanation

The verb 'will have graduated' is in the future perfect tense. This tense is used to show that an action will be finished by a certain point in the future.

Complete the sentence with the most logical verb tense: 'Before the guests arrived, we ______ the entire house.'

• had cleaned

• will clean

• are cleaning

• clean

Answer explanation

The past perfect tense 'had cleaned' is needed here. It shows that the action of cleaning was completed before another past action (the guests arriving).

Which sentence contains an error in subject-verb agreement?

• The pack of wolves howl at the moon.

• Across the street live my best friends.

• The news from the reporters was shocking.

• My brother and sister want a new video game.

Answer explanation

The subject is 'pack' (singular), not 'wolves'. Therefore, the verb should be singular: 'howls'. The prepositional phrase 'of wolves' does not change the number of the subject.

Choose the correct verb to complete the sentence: 'Each of the players ______ a new uniform for the championship game.'

• needs

• need

• are needing

• have needed

Answer explanation

The indefinite pronoun 'Each' is the subject and is always singular. Therefore, it requires the singular verb 'needs'.

Complete the sentence with the correct verb for this inverted structure: 'On the top shelf of the bookcase ______ the old, dusty trophies.'

• sits

• is sitting

• sit

• has sat

Answer explanation

In an inverted sentence, the subject comes after the verb. The subject here is 'trophies' (plural), so the plural verb 'sit' is correct.

Consider the passive sentence: 'The winning goal was scored by Maria.' Which option correctly rewrites the sentence in the active voice and identifies the agent?

• Active: Maria scored the winning goal. Agent: Maria.

• Active: The winning goal scored Maria. Agent: The winning goal.

• Active: Maria was scored by the winning goal. Agent: Maria.

• Active: The goal was winning and scored by Maria. Agent: The goal.

Answer explanation

In the active voice, the agent (the one doing the action) becomes the subject. 'Maria' is the agent who performed the action of scoring, so she becomes the subject of the active sentence.

For which of the following situations would the passive voice be most effective and appropriate?

• A science lab report where the focus is on the experiment, not the person who did it (e.g., 'The beaker was heated.').

• A text message to a friend telling them what you did today (e.g., 'The mall was visited by me.').

• A story about a hero where you want to emphasize their actions (e.g., 'The dragon was slain by the knight.').

• An instruction manual where you are giving direct commands (e.g., 'The button should be pressed by you.').

Answer explanation

The passive voice is most effective in scientific or formal writing when the action or the result is more important than the person who performed the action.

True or False: In the sentence 'The cookies were baked by my grandmother,' the verb 'were baked' is in the passive voice and the agent is 'my grandmother.'

• True

• False

Answer explanation

This is true. The subject 'The cookies' is receiving the action, the verb is a 'be' verb plus a past participle ('were baked'), and the agent doing the action ('my grandmother') is in a prepositional phrase.

In the sentence 'My brother should have been studying for his test all weekend,' what is the complete verb phrase?
