1. What did Alice do when you came? She was sleeping.
- Explanation: We use the past simple tense to talk about completed actions in the past. "Alice" did something when "you" came, so we use the past simple "did". The action "sleep" happened at the same time, so it is in the past continuous tense "was sleeping".

2. By the time I heard the news, she had already left.
- Explanation: When we talk about an action that happened before another action in the past, we use the past perfect tense. "I" heard the news after she had left, so "she had already left" is in the past perfect tense.

3. When my friend met his future wife, he had been living in London for 3 years.
- Explanation: We use the past perfect continuous tense to talk about an action that started in the past and continued up to a specific point in the past. Before meeting his future wife, he had been living in London for 3 years, so we use the past perfect continuous "had been living".

4. When I saw her, her eyes were red. I think she had been crying.
- Explanation: "I" saw her in the past, so we use the past simple tense "saw". Her red eyes indicate a past action, so we use the past continuous tense "were". Based on the evidence of her red eyes, we assume she had been crying, so we use the past perfect continuous "had been crying".

5. While my sister was cooking, I was watching TV.
- Explanation: Both actions are happening at the same time in the past, so we use the past continuous tense for both verbs "was cooking" and "was watching".

6. It has been raining since morning, but he didn't take an umbrella.
- Explanation: "It has been raining" indicates an ongoing action that started in the past and continues until now, so we use the present perfect continuous tense. However, "he didn't take an umbrella" is a completed action in the past, so we use the past simple tense "didn't take".

7. When I arrived at the station, the train had already left.
- Explanation: When we talk about an action that happened before another action in the past, we use the past perfect tense. The train left before I arrived, so "the train had already left" is in the past perfect tense.
