动词不定式的用法

sire, determination, decision, effort, failure, intention, need,

opportunity, plan, promise, pressure, right, tendency, time, way等。 【例如】

His efforts to carry out the plan were successful.I have no intention to go to the cinema with you. There is no need to bother him with such trifles.

There is a tendency to writer quite long sentences in commercial correspondence.

The pressure( )causes Americans to be energetic, but it also put them under a constant emotional strain. (CET-4 1997,6) A) to compete B) competing C) to be competed D)shavingscompeted

pressure后面应接后置定语，表示竞争的压力。单个分词作定语一般置于名词前，故B和D可以排除。C为不定式的被动式，而竞争和压力之间没有被动关系，

因此正确答案为A。特别注意的是在不定式与其修饰的名词有动宾关系时，要根据句子的需要在不定式后加适当的介词，这个介词的选用取决于被修饰的名词或不 定式本身的要求。 【例如】

She is a very nice person to work with.

This is an important issue to talk about.

b)由only, last, next,序数词或形容词最高级修饰的名词常用不定式作定语。 【例如】

Mr. Zhang is always the first man to arrive at the office and the last man to leave.I don't think he is the best one to do the work.

9)不带to的不定式在下列词组后面的不定式不带to：would rather ...than(宁愿……也不), had better...(最好)，can't help but...(不得不), had

rather...(宁愿)，cannot but...(不得不，必然)，may/might as well...(不妨)，let alone(更不用说)。 【例如】

You'd better return the books to the library on time. Otherwise, you will be fined.

I can't help but wish that nothing would go wrong.
