英文四大句型
一．S+V+O S-----主語(yǔ)從句，what/whether/how
不定式（邏輯主語(yǔ)）
動(dòng)名詞（邏輯主語(yǔ)）
名詞+定語(yǔ)從句/介賓短語(yǔ)
V------幾個(gè)謂語(yǔ)動(dòng)詞平行
O-----how/what賓語(yǔ)從句
倒裝加大難度
Among top students are you
Among the top students, you are the best
主謂賓從句也可倒裝-----賓語(yǔ)從句可倒裝在前面
如果怎么也讀不懂，有可能主謂賓有倒裝了
賓語(yǔ)后置------set something in motion
二．---------------，S+V+O 作狀語(yǔ)4種形式 1． When, since, because, if, though, before引導(dǎo)狀語(yǔ)從句
Though (you are ) young, you can understand it.
沒有主句就沒有從句的生命力
狀語(yǔ)從句的省略原則：狀語(yǔ)從句與主句主語(yǔ)是一致的，并且狀語(yǔ)從句包括謂語(yǔ)動(dòng)詞be(am, is, are或其他時(shí)態(tài)形式)
We, because we are late, are punished.
2. To do 不定式放在句首
For me to learn English well, my mother went to the lecture. ----加for sb.邏輯主語(yǔ)構(gòu)成復(fù)合結(jié)構(gòu)
3．Doing/done, S+V+O doing---主語(yǔ)發(fā)出動(dòng)作；done----主語(yǔ)承受動(dòng)作
Singing and dancing, the children went back home
Judged guilty, Tyson was sentenced to prison several years ago.
Doing/done同主句的謂語(yǔ)動(dòng)作發(fā)生動(dòng)作如果有一段距離，用Having done/Having been done
Having done = doing的完成形式
Having been done = done的完成形式
4. 介賓短語(yǔ)-----有時(shí)移到主謂之間
In Wuhan, we met with each other.
三．S，---------------，+V+O 空格處5種形式, 后四種是第一種的省略形式
1、Whose, who, when, which, in which引導(dǎo)的定語(yǔ)從句----沒有that引導(dǎo)從句

Dalian, (which is) my hometown, is very beautiful.
3、Done/doing

5、the first+名詞+to do
