谓语动词：顾名思义，在句中充当谓语，形式与句子时态相关。
例如：一般现在时态，谓语动词有原形和三单两种形式。
He gets up at 5:00 o’clock every day.
一般过去时态，谓语动词形式为过去式。
We went to Hong Kong last summer.
非谓语动词：是相对于谓语动词而言的，非谓语动词不担任谓语成分,且具有其他词类特征的动词形式，
即不定式，动名词和分词（现在分词和过去分词）。
例如：My teacher told me not to make noise in class.
Watching movies help me learn English.
The man standing under the tree is my father.
I had my hair cut yesterday.
用法：
(1)不定式作主语
It 作形式主语常见结构：
▲ “It is + adj./n+(for sb.) to do sth .
例：It is important for us to keep a balanced diet.
▲ It is + adj.+of sb+ to do sth
(在 kind，good, nice, clever 等表示人的品质的形容词后,介词要用 of)
例：It is silly of you to lend him money again.
▲ It takes sb. +一段时间+ to do sth.
例：It takes me three hours to finish the task.
（2）不定式作宾语
A. 放在动词后作宾语
初中阶段后加 to do 的动词（必背）
•want to do sth 想要做某事
•plan to do sth 计划做某事
•promise to do sth 承诺做某事
•expect to do sth 期待做某事
•hope to do sth 希望做某事
•choose to do sth 选择做某事
•decide to do sth 决定做某事
•manage to do sth 设法做成某事
•fail to do sth 未能做成某事
•would like to do sth 想要做某事
•offer to do 主动提出做某事
•afford to do sth 承担得起做某事
注意：使役动词和感官动词后不能＋to do
一感 feel/
二听 hear, listen to/
三让 let, make, have/
四看 look at, see, watch, notice
B. it 做形式宾语代替不定式, 常见结构有 find/ think/ make...+ it +adj.+ (for sb.) to do sth.（初二学生可做拓
展）
Eg. I found it hard to finish the work before 9:00.
C. 动词不定式可以用在疑问词 what，how，when，where,，which 等之后。
Eg：I don’t know what to say.
（3）作宾语补足语
1) Tell，ask，want，order，teach，invite，wish，warn，allow 等+sb. /sth. + (not) to do sth
例：I told them not to draw on the wall.
My brother taught me to read when I was three.
2) help sb. (to) do.
