finish
1.finish后面接动名词，不接不定式，如可以说I have finished correcting the composition，不可说I have finished to correct the composition。
2.finish有“吃完”、“做完”、“读完”、“写完”等意思，如可以说I have finished the dinner, I have finished the work, I have finished the book和I have finished the letter。在finished后面加上eating, doing, reading, writing等词也不错，但不必要。I have finished the book可能有两个意思：“我已经读完这本书！”或“我已经写完这本书”。I have finished the letter也可能有两个意思。在有可能被人误解时该加上writing, reading等词。
3.下面两句意思相同，都作“我已经完毕了”解：
- I have finished with it.
- I am finished with it.
第二句里的finished是不及物动词的过去分词用作形容词。finished在用作形容词的时候后面有时接with和动名词，偶尔省去with而使动名词成为现在分词。例如：I waited for him to be finished (with) dressing. Finished with his breakfast, he talked to us over a cup of tea里的Finished也是用作形容词。
4.If he is not interrupted, he can finish by five o'clock里的finish是不及物动词，在口语里通常改用get it done。
5.finish有时有表语，作“结果成为…”解，如He finished a famous scholar和He finished perfectly proficient。
6.finish up比finish语气强，例如：If I don't finish the work tonight, I'll surely finish it up tomorrow. 和When the children had finished up with the ices, he asked the waiter, for the bill.
7.finish是一时的动作，所以不可说I have finished the work for a week，该改作I finished the work a week ago或It is a week since I finished the work。
8.fight to a finish（打到底、战斗到底）比fight to the finish普通。
