初中英语知识点：动词不定式

初中英语知识点：动名词
动名词既具有动词的一些特征，又具有名词的句法功能。
1、动名词的形式，以write为例。
否定式 not +动名词
2、动名词的用法
(1) 作主语
Playing football is my favorite sport.
Travelling with friends at weekend is fun.
作主语的动名词结构复杂且长时，可用it作形式主语。如：

(2) 作宾语
I enjoy playing PC game.
He gave up writing five years ago.
(3) 作表语

Seeing is believing.
动名词作表语时，句子的主语常是无生命名词或what引导的名词性从句。
(4) 作定语

All the people watching laughed.
(5) 动名词的复合结构"物主代词(或名词的所有格)+动名词"。如：
Tom's going home late made her mother angry.
Would you mind my opening the window?
不过，动名词的逻辑主语在遇到以下情况时，必须用名词的普通格(或人称代词的宾格)。
① 无生命名词
The girls were afraid of the door suddenly closing.
Fire burns better by oxygen being at work.
② 有生命名词，但表泛指。
Have you ever heard of girls smoking?
③ 两个以上的有生命的名词并列。
Do you still remember my parents and me coming to see you that day?
3. 后面常接动名词的动词和短语

初中英语知识点：分词
分词既具有动词的一些特征，又具有形容和副词的句法功能。它分为现在分词和过去分词两类。现在分词和过去分词的主要差别在于现在分词有一般式和完成式，过去分词则只有一般式。现在分词表动作正在进行，表主动。过去分词及物动词表动作已经完成，表被动。过去分词不及物动词表动作已经完成，表主动。
过去分词的句法功能：
1、作定语
I like to read the novel written by Lu Xun.
The woman sitting beside the broken window was a friend of mine.
2、作表语
When I came into the room, I found the window was broken.
I'm interested in this book.
3、作宾语补足语
I'm going to have my bike repaired.
When I walked home, I saw the thief caught by the police.
4、 作状语
Seen from the top of the mountain, the city looks small.
The teacher came into the classroom, followed by his students.
现在分词的句法功能。
1、 作状语
Seeing from the top of the mountain, I found the city was beautiful.
Walking along the street, they suddenly saw him.
2、 作宾语
I hate being spoken ill of.

3、 作表语

4、 作宾语补足语

3、 现在分词与过去分词的不同

4、 have结构
