Answer 2

1. We used to drive to work, but now we use public transport.

- Explanation: "Used to" is used to talk about past habits or states that are not true in the present. In this case, the past habit is driving to work. The correct form is "used to drive" for the past habit, and "use" for the present situation.

2. By the evening, they had reached the petrol station.

- Explanation: "Had reached" is the correct form of past perfect here. It indicates that the action of reaching the petrol station was completed before another past action or time (by the evening).

3. There weren't so many traffic jams 50 years ago.

- Explanation: "Weren't" is the correct past simple form here. "Used to be" is used for past habits or situations, but in this case, we are stating a fact about the past, so the simple past is appropriate.

4. I came to help Jim with the bottles, but he had already gone to the recycling center.

- Explanation: "Had already gone" is the correct form of past perfect, indicating that Jim went to the recycling center before your arrival.

5. I had thrown all the rubbish before my parents came.

- Explanation: "Had thrown" is the correct past perfect form here. It indicates that the action of throwing the rubbish was completed before another past action or time (before your parents came).

6. By the time we came, the pupils hadn't finished cleaning up the park yet.

- Explanation: "Hadn't finished" is the correct past perfect form here. It indicates that the action of finishing cleaning up the park was not completed before another past action or time (by the time you came).

7. She had saved electricity when she lived in the city.

- Explanation: "Had saved" is the correct past perfect form here. It indicates that the action of saving electricity occurred before another past action or time (when she lived in the city).
