Exercise 3 out of 3 Complete the task. Complete the sentences with the correct forms of the verbs below. There are two extra verbs. Don't use contractions.
Write 1–3 words in each gap.
to do, to invite, to study, to bring, to have, to promise, to surf, to wait
1. Tim was angry; he___
for us since seven o'clock! We apologised and then___
not to be late again.
2. I___
the net in my room when I heard the cat meowing loudly. I didn't need to feed the cat because I___
it ten minutes before.
3. We saw David and said hello to him. We___
him to go to the cinema with us, but he was too tired because he___
for the test all day long.
To solve this sentence, we need to use the past perfect continuous tense because Tim had been waiting for us for some time before we arrived. Therefore, we use "had been waiting" as the correct form of the verb "to wait" in this sentence. The word "for" is also necessary to indicate the duration of waiting.
2. I was surfing the net in my room when I heard the cat meowing loudly. I didn't need to feed the cat because I had fed it ten minutes before.
In this sentence, the past perfect tense is used to indicate an action that occurred before another past action. Before hearing the cat meowing, I had already fed it. Therefore, we use "had fed" as the correct form of the verb "to feed" in this sentence.
3. We saw David and said hello to him. We invited him to go to the cinema with us, but he was too tired because he had been studying for the test all day long.
In this sentence, the past perfect continuous tense is used to indicate an action that started in the past and continued up until another past action. David had been studying for the test for the entire day, so he was too tired to go to the cinema. Therefore, we use "had been studying" as the correct form of the verb "to study" in this sentence.
