二、重难点讲解：
语法讲解：动词不定式
基本形式：to+动词原形（在某些情况下可以不带to）
动词不定式在句子中的不同成分
(1)Subject不定式做主语时常能换成it做形式主语的句型，如：
To plant trees every year is necessary.
常被转化为： It is necessary to plant trees every year.
(2) Predicative不定式可以用作表语，跟在系动词的后面，如：
Her dream is to be a dancer.
(3)Object不定式可以用作宾语，跟在某些动词后面，如：
They want to play football this Sunday.
有以上结构的常用动词：
agree, choose, decide, fail, hope, wish, learn, forget, remember, like,
happen, hate, plan, try, begin, start, refuse, promise, afford, offer等
（4） Object complement
不定式可以用作宾语补足语，此时它与宾语具有逻辑上的主谓关系，如：
My mother tells me to ride a bike on a sunny day.
有以上结构的常用动词：
wish, ask, want, like, beg, invite, warn, allow, advise, encourage, teach等
help后既可以带to，也可以不带to。
(3) Attributive
不定式可以用作定语，通常放在被修饰的词语之后，如:
Have you got anything important to tell me.
(4) Adverbial不定式还可以用作状语，分为目的状语和结果状语，如：
I came to chat with you.（目的）
Linda came back home to find her house on fire.（结果）
★★★动词不定式to的省略
在感官动词see, hear, feel, watch, notice及使役动词have, make, let等后面复合宾语的动词不定式可以省略to，但在变被动语态时，要加上to如：
Millie’s parents make her do a lot of exercises every day
Millie is made to do a lot of exercises by her parents every day.
★★★ 动词不定式的否定形式：not + to do，有时也可以用never + to do 结构
★★★当两个动词不定式由and连接，则后一个不定式通常省略to。如：
He told me to finish my homework and hand it in on time.
她鼓励我说英语并且与外国人交谈。
