高考英語從屬連詞知識點歸納
這種連詞是用以引導名詞性從句定語從句和狀語從句的，由從屬連詞所引導的句子叫從句,而含有從句的句子叫作復合句。
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：
從結構上說，英語連接詞分兩大類：并列連詞和從屬連詞。
并列連詞連接兩個或兩個以上地位平等的字、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.
從屬連詞連接兩個或兩個以上的分句，形成復雜句中的從屬分句。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表達時間狀語的句子中，主句中的動詞是要十分小心去選擇的。
如動詞是持續(xù)行動詞，它要用肯定句，如：
I studied hard until 12 o'clock last night.
如果動詞是瞬間截止性動詞，則要用否定句，如:
He didn't go to bed until his mother came back.
由since,for,by,before, 來引導的時間狀語從句。
since 引導的時間狀語是動作的開始時間，如:
I have studied English since 1990.
而by引導的時間狀語通常是動作的結束時間，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 | 引導原因狀語從句 | Because, since |
| 引導條件狀語從句 | If, unless, as long as | |
| 引導目的狀語從句 | So that | |
| 引導結果狀語從句 | So…that | |
| 引導方式狀語從句 | As, just as, as if | |
| 引導讓步狀語從句 | Though, although, even though, no matter what, however, no matter how, whoever, no matter who, wherever, no matter where | |
| 引導比較狀語從句 | As…as, not so…as, than, less…than, the more…the more | |
| 引導名詞性從句 | Who, whom, whose, which, that, when, where, why |
