1. You are late! The lesson has already started.
2. We have moved (assuming this implies a recent moving action).

4. Jack was playing basketball with his cousins last weekend (ongoing action).
5. Peter has read three books last month (completed action).
6. They left the party early last night (past action).
7. I went to the restaurant with a client yesterday (past action).

1. It was cloudy yesterday.
2. We moved to another city in 1990.
3. My mother made two cakes four days ago.
4. Nancy didn't watch TV last night.

Note:

• In sentence 1, "It" is the subject, so we use the third person singular verb "was".
• In sentence 2, the action occurred in the past and there is no indication of it being recent, so we use the simple past tense "moved".
• In sentence 3, the action happened four days ago, so we use the past perfect tense "made".
• In sentence 4, we use the negative past simple tense "didn't watch".

I hope this helps! Let me know if you have any other questions.
