动词不定式用法：
1.动词不定式的基本形式是“to+动词原形”，有时可以不带to。
2.不定式在句中不能单独作谓语，是一种非谓语动词结构。
3.不定式保留动词的某些特性，可以有自己的宾语、状语等。
4.动词不定式可以作句子的主语、表语、宾语、定语、补语、状语。
动词不定式例子：
to live in Fuzhou
to read a book
to talk with the boy
to learn English well
动词不定式作定语时，常放在被修饰的名词或代词的后面，作后置定语。
1.一般情况下，不定式与其所修饰的名词或代词之间存在逻辑上的动宾关系(即名词或代词是不定式动词的逻辑宾语，也就是动作的对象). 有时不定式中的动词后要加上相应的介词。
1) She has much homework to do.他有许多作业要做。(todo homework)
2) I have so many clothes to wash today. 我今天有许多衣服要洗。 (towash clothes)
3) I "d like something to eat. 我想要吃点东西。(toeat something)
4) We have no houses to live in. 我们没有房子住。(tolive in houses)
5) Do you have any paper to write on? 你有用来写的纸吗？ (towrite on paper)
6) He"d like to look for a restaurant to eat at.他想要找个饭店吃饭。
(toeat at a restaurant)
2. 动词不定式所修饰的名词是time, way等时，不定式与这些名词呈现出动状关系；
不定式所修饰的名词是place时，不定式中的动词后面通常不带介词。
1)He needs time to do homework. 我需要时间来做作业。
2) He wants to know the best way to travel around the city.
他想知道全城观光的最好方法。
3）In fact,it is a wonderful place to live.
实际上，这是个居住的好地方。
