英语的主语有哪些10个

名词，代词，名词化了的动词，形容词，分词，副词，数词，动词不定式或不定式短语， 从句，某些固定词组。例：She would be good for the job.她干这工作很合适。

名词作主语

例：The villagers didn't realize how serious the pollution was until the fish in the river died.　　直到河里的鱼死了，村民们才意识到污染的严重性

S（subject主语）+ V（verb谓语动词） +O（object宾语）. 主系表结构 :S（subject主语）+V（verb谓语动词，也称为系动词，就是所说的“系”）

倒装：Not until the fish in the river died did the villagers realize how serious the pollution was.

注意：倒装在主句，从句不倒装 /did 和not 提前，只剩动词原形

强调：It was not until the fish died in the river that the villagers realized how serious the pollution was.

如果强调的是主语或宾语且指人用who，其他一律用that。是that，而非其他/主句的顺序（倒装不强调，强调就不倒装）

人称代词（主格），名词性代词，指示代词，不定代词，such（----样的人、物），it（时间，天气，距离等）

at midnight /in the(泛指）middle of the night

例：It is 9 o'clock when I went home.

我回家的时候已经九点了

一般句：It was nine when I got home.

强调句：It was at nine that I got home.

原形：I got home at nine.

注意：作主语在句首/it作主语构成（常用 v-ing，不常用只有 use，good）

（1）It is +adj. +of sb.(人的属性）/for sb.（物的属性）to do

例：It is necessary to finish the design before National day. Tomorrow is National day.

有必要在国庆节之前完成设计。明天是国庆日

（2）it is +n.+for/of sb. to do

例：It is not good manners for Arabs to stand close talking to their friends.

对阿拉伯人来说，和他们的朋友说话离得近不是一个好习惯

在感叹句中必须用it作形式主语：What a joy/ pleasure (it is) to read the book.
