suggest
1.suggest后面接动名词，不接不定式，如可以说I suggest asking her advice，不可说I suggest to ask her advice。也不可说I suggest for him to ask her advice，该改作I suggest that he should ask her advice 或I suggest that he ask（不用asks）her advice。
2.suggest（建议）后面可以接以that引导的从句，从句里用should或属于虚拟现在式的动词。例如：
- He suggests that the regulations should be revised.
- He suggests that the regulations be（不用are）revised.
- He suggested that the regulations should be revised.
- He suggested that the regulations be（不用were）revised.
