Question
In pairs. For each pair of sentences decide which is correct and explain why.
Answer
1
- Correct: My mother used to have long, fair hair.
- Explanation: "Used to" is correctly used to describe a past habit or state that is no longer true. "Would have" is incorrect in this context because "would" is used for habitual actions in the past, not states or conditions.
2
- Correct: Mike took a course in IT when he was at university.
- Explanation: "Took" is the correct simple past tense verb to describe a specific action completed in the past. "Used to take" implies a repeated or habitual action, which is not appropriate here.
3
- Correct: My sister used to be shy when she was young but she seems to have changed now.
- Explanation: "Used to be" correctly indicates a past state that has changed. "Would always be" is incorrect because "would" typically describes repeated actions, not states.
4
- Correct: You used to like Bob, but now you hate him.
- Explanation: "Used to like" correctly describes a past state that has changed. "Would like" is incorrect because "would" describes habitual actions, not changes in feelings or states.
5
- Correct: She used to live in London before she got married.
- Explanation: "Used to live" correctly indicates a past state that has changed. "Would live" is incorrect because "would" is used for habitual actions, not states.
6
- Correct: Did you use to play tennis when you were at school?
- Explanation: "Did you use to" is the correct question form to inquire about past habits or actions. "Would you use to" is incorrect because "would" does not fit grammatically in this question form.
