1. 动词不定式的用法 :(1)不定式做宾语: eg: I want to buy some flowers for my mother. 我想给我妈妈买些花。常见的跟动词不定式做宾语的动词: want (想要 ), expect ( 期望) , hope (希望), plan (计划) , decide(决定) , try(尝试) ,choose(选择),would like (想要)(2)省略to的不定式 (有些动词后面跟动词不定式时, 应将不定式符号to省去。常见的动词有 let, make, have, help等)。
eg: Let me help you.
不定式有时和特殊疑问词一起构成宾语。 e.g. I don't know what to say.我不知道说什么。
2. 动词不定式作主语时,常用it作形式主语,而把真正的主语--不定式后置。
eg: It's hard to learn a language well. 学好一门语言是非常难的。
3. 动词不定式作定语时,要放在所修饰词的后面。
e.g. Would you like something to drink? 你想要喝的东西吗?
4. 动词不定式可作宾语补足语。
e.g. My mom asks me to drink milk every day.我妈妈要求我每天喝牛奶。
5. like, love, begin, start等动词后既可以接动词不定式也可以接动名词形式, 意义上差别不大。
如: I like singing, but I don't like to sing now.
stop, forget , remember , try 等动词后既可以接动词不定式也可以接动名词形式,但意义上有差别。
stop to do sth.停下来做某事 stop doing sth.停止做某事 forget to do sth. 忘记要做某事forget doing sth . 忘记做过某事 remember to do sth. 记得要做某事remember doing sth. 记得做过某事try to do sth.尽力做某事 try doing sth. 尝试做某事
6."find/think+it+形容词+动词不定式"结构,其中it为形式宾语,动词不定式为真正的宾语。如:I find it difficult to learn English.我发现学英语很难。
动词不定式的用法(顺口溜):不定式有标记,to与动词连一起;没有人称、数变化,动词特点它具备;主宾定表及状语,唯独谓语不可以;not加上不定式,否定结构要牢记;疑问词与不定式,构成短语有意义;仔细推敲多考虑,准确判断有依据。
