【答案】
1. A 解析：在表推测的情态动词中can常用于否定句中，can’t表示不可能。Mustn’t表禁止，needn’t表不必，may not表可能性很低的不可能。
2. C 解析：ask sb for help表示向某人求助。
3. C 解析：enough与形容词连用时，形容词应该至置于enough前，表示足够---，但如果是名词，那名词就应该置于enough后。
4. A 解析：本题考查感叹句。解题技巧，把主谓去掉后，剩名词用what,剩形容词或副词用how。本题该用how.本题的slow应该是在be动词后的所以用形容词，不用副词。可以这么理解，把本句还原后是The boy is slow to learn to talk.所以不能用B。
5. D 解析：本题中宾语，还原成陈述句应该是the museum is the one they visited last month. they visit是省略关系词的定从修饰the one.
6. D 解析：weather天气，temperature温度，season季节，climate气候。
7. C 解析：本题考查代词用法，本题中的one是泛指的break.
