c.与被修饰之间只有修饰关系。 如： I have no time to play cards. 6.作状语，表示目的、原因、方法、方向、结果等。 如： I'll go to meet my friend at the railway station. 7.不定式复合结构"for sb. to do sth" 作主语时，常用"It is +adj+ for of sb. to do sth"的句式。形容词good, bad, polite, unkind, kind, ice, clever, right, wrong, careful等用"It is +adj +of sb. to do sth." 其他形容词用 for。 如： It's dangerous for you to ride so fast. It's very kind of you to help me. 8.动词不定式与疑问句who, what, which, when, how, where, whether等连用。 如： I don't know when to start. He didn't tell me where to go. 但上面结构相当于一个从句，故上述句子也可表达为： I don't know when we'll start. He didn't tell me where he would go. 注意： a.有些动词或动词短语不能带不定式，只能接动词的-ing形式。 如： enjoy, finish, keep, mind, miss(错过),be busy, go on, keep on, be worth, practise等。 如： The peasants are busy picking apples. Would you mind my opening the door? b.有些动词后可接不定式，也可接动词的-ing形式，但意思不同。 如： Lu Jian forgot to post the letter.(该寄但还没做) Lu Jian forgot posting the letter.(已经寄过信了) They stopped to sing a song.(停止在做的工作而去做另一件工作) They stopped singing.(停止正在做的工作) (责任编辑：admin) |
