can't 和 mustn't 的用法區(qū)別
1. can't 根據(jù)其基本用法可譯為:
(1) 不會。例如:
I can't speak English. 我不會說英語。
(2) 不能。例如:
We can't do it now because it's too dark.天太黑了,我們現(xiàn)在干不了。
(3) 否定句中表示推測,意為“不可能”。例如:
The man can't be our teacher because he is much younger than our teacher.
那個人不可能是咱們老師,他年輕得多。
2. mustn't 意為“禁止、不許”, 用來表達(dá)命令,表示強(qiáng)烈的語氣。 例如:
You mustn't play football in the street. It's too dangerous.你不可以在街上踢足球,太危險了。
