“情态动词:推断现在的事” (Modals: deductions about the present)
🔒 登录后可标记已读- 推断过去要加 have + 过去分词,推断现在的情况就单纯多了,情态动词后面直接接原形动词。
- must 表示几乎确定(一定是),can't 表示几乎确定不是(不可能)。
- might / may / could 表示不确定但有可能,三者意思相近,may 最正式,might/could 口语更常用。
- 所有情态动词后面都接原形动词,不能再加 be 动词(不是 must is,而是 must be)。
- B1 核心语法,生活对话和考试都常见,跟上一篇推断过去的用法正好对照。
