| 词组 | know |
| 释义 | 1．know 作“认识（某人）”解，know of 作“知道有（某人）”解。例如：I know of him, but do not know him (personally). 说“知道有……”必须用 of。例如：Do you know of any such shop in your city? 但 know the fact 和 know of the fact 都可以说。 2．I am glad to learn that...等句子里通常用 learn，不用 know。 3．Who do you think he is? 等句子里该用 think，不可用 know。 4．have known 后面接宾语和不定式的时候，那不定式可以有 to，也可以没有 to。例如：I have known him (to) say this before. never knew 和 have never known 后面接宾语和不定式的时候，那不定式没有 to，如 I never knew him say this before 和 I have never known him say this before。假使 have known，never knew 或 have never known 改成被动语态，那不定式必须有 to。例如：He has been known to say this before. He was never known to say this before. 和 He has never been known to say this before. 假使 have known，never knew 或 have never known 的宾语后面的不定式是 be，必须有 to。例如：I have known him to be too busy to study. I never knew him to be too busy to study. 和 I have never known him to be too busy to study. 5．注意下面第一句里用 I know it，第二句里用 I know： He is going to get married, and I know it. When his sister said that he was going to get married, I said, 'Yes, I know.' |
