高考英語從屬連詞知識點(diǎn)歸納
這種連詞是用以引導(dǎo)名詞性從句定語從句和狀語從句的，由從屬連詞所引導(dǎo)的句子叫從句,而含有從句的句子叫作復(fù)合句。
從屬連詞可分為三大類：
1、that (無詞義，不做成分)
if，whether (表達(dá)是否的意義，但不做句子成分)
2、連接代詞：who，whom，whose，what，which，whatever, whoever, whichever(有詞義，在句子中可作主語、表語、賓語)
3、連接副詞：when，where，why，how，how many，how long，how far，however，whenever，wherever (有詞義，作從句的狀語)
用法：
從結(jié)構(gòu)上說，英語連接詞分兩大類：并列連詞和從屬連詞。
并列連詞連接兩個(gè)或兩個(gè)以上地位平等的字、詞組或分句。例如：
(1) Air and water are indispensable to me.
(2) She likes going out with friends or playing outdoor games.
(3) Most workers have a good income, so they look very happy.
從屬連詞連接兩個(gè)或兩個(gè)以上的分句，形成復(fù)雜句中的從屬分句。例如：
(4) He said that he did not want to go .
(5) Many things have happened since I last saw him.
(6) You may come if you want to.
從屬連詞用來連接各種從句。
until(till)直到，在用until表達(dá)時(shí)間狀語的句子中，主句中的動(dòng)詞是要十分小心去選擇的。
如動(dòng)詞是持續(xù)行動(dòng)詞，它要用肯定句，如：
I studied hard until 12 o'clock last night.
如果動(dòng)詞是瞬間截止性動(dòng)詞，則要用否定句，如:
He didn't go to bed until his mother came back.
由since,for,by,before, 來引導(dǎo)的時(shí)間狀語從句。
since 引導(dǎo)的時(shí)間狀語是動(dòng)作的開始時(shí)間，如:
I have studied English since 1990.
而by引導(dǎo)的時(shí)間狀語通常是動(dòng)作的結(jié)束時(shí)間，如：
I had learned 25 English songs by the end of last term.
從屬連詞語法分類：
| 種類 | 語法作用 | 連詞舉例 |
| 從屬連詞 | 引導(dǎo)原因狀語從句 | Because, since |
| 引導(dǎo)條件狀語從句 | If, unless, as long as | |
| 引導(dǎo)目的狀語從句 | So that | |
| 引導(dǎo)結(jié)果狀語從句 | So…that | |
| 引導(dǎo)方式狀語從句 | As, just as, as if | |
| 引導(dǎo)讓步狀語從句 | Though, although, even though, no matter what, however, no matter how, whoever, no matter who, wherever, no matter where | |
| 引導(dǎo)比較狀語從句 | As…as, not so…as, than, less…than, the more…the more | |
| 引導(dǎo)名詞性從句 | Who, whom, whose, which, that, when, where, why |
