To complete these sentences, we need to choose the correct verb tenses based on the context given in each sentence. Let's go through them one by one:
'Peter ____ (go) to Paris when he was a student but he ____ (not go) back since then.'
For the first blank, the past simple tense should be used because it refers to an action completed in the past. The correct form is 'went.'
For the second blank, we use the present perfect tense to describe an action that has not happened up to the present time. The correct form is 'has not gone.'
Completed sentence: 'Peter went to Paris when he was a student but he has not gone back since then.'
'It ____ (not be) a fair race. I ____ (run, never) that distance before but Vicky is a long-distance runner.'
For the first blank, we should use the past simple tense to indicate a definite action or state in the past. The correct form is 'was not.'
For the second blank, the present perfect tense is suitable since it refers to an experience up to the present moment. The correct form is 'have never run.'
Completed sentence: 'It was not a fair race. I have never run that distance before but Vicky is a long-distance runner.'
'You ____ (eat) all the cakes! I ____ (make) those for all of us.'
For the first blank, the present perfect tense is used to express a recently completed action with relevance to the present. The correct form is 'have eaten.'
For the second blank, the past simple tense works here, indicating a completed action in the past. The correct form is 'made.'
Completed sentence: 'You have eaten all the cakes! I made those for all of us.'
Each sentence uses the correct tense to align with the timing or situation described, ensuring clarity in communication.
