seem
1.下面四句意思不同：
- She seems to be a musician. （她［现在］似乎是一个音乐家。）
- She seemed to be a musician. （她［从前］似乎是一个音乐家。）
- She seems to have been a musician. （她［现在看来］似乎曾经是一个音乐家。）
- She seemed to have been a musician. （她［在过去的某时看来］似乎曾经［在那时的以前］是一个音乐家。）
2.it would seem或it should seem语气比it seems婉转。现在it would seem比it should seem普通。
3.seem后面不可接as，但可以接as if。
4.He seems not to like it和He does not seem to like it都可以说。
5.下面两句都是美国口语：
- I can't seem to do it.
- He couldn't seem to solve the problem.
通常该把这两句改作：
- I seem (to be) unable to do it.
- He seemed (to be) unable to do it.
