31.3 In some of these sentences, must is wrong or unnatural. Correct the sentences where necessary. 1 It's later than I thought. I must go. 2 I must work every day from 8.30 to 5.30. 3 You must come and see us again soon. 4 Tom can't meet us tomorrow. He must work. 5 I must work late yesterday evening. 6 I must get up early tomorrow. I have a lot to do. 7 Julia wears glasses. She must wear glasses since she was very young.
Ответ:
Краткое пояснение: 'Must' используется для выражения сильной личной необходимости, запрета или для констатации факта, который кажется говорящему неоспоримым. В некоторых случаях 'have to' звучит более естественно для выражения внешней обязанности или правила.
Пошаговое решение:
- 1. It's later than I thought. I must go. - OK (have to is also correct). 'Must' здесь уместно для выражения личной необходимости.
- 2. I must work every day from 8.30 to 5.30. - I have to work every day from 8.30 to 5.30. - 'Have to' лучше передает правило или обязанность, установленную кем-то другим (работодателем).
- 3. You must come and see us again soon. - OK. 'Must' выражает сильное желание или просьбу.
- 4. Tom can't meet us tomorrow. He must work. - OK. 'Must' здесь передает уверенность говорящего в причине отсутствия Тома.
- 5. I must work late yesterday evening. - I had to work late yesterday evening. - 'Must' не используется для прошлого времени. Нужна форма 'had to'.
- 6. I must get up early tomorrow. I have a lot to do. - OK. 'Must' здесь выражает личную необходимость, продиктованную большим количеством дел.
- 7. Julia wears glasses. She must wear glasses since she was very young. - Julia wears glasses. She has had to wear glasses since she was very young. - 'Must' не используется для выражения продолжительного состояния или обязанности, начавшейся в прошлом и продолжающейся до настоящего времени. Нужна форма 'has had to wear'.
