狀語從句知識點(diǎn)總結(jié)：原因狀語從句
【導(dǎo)語】英語語法讓很多學(xué)生都頭疼，因?yàn)閺?fù)雜難懂的句式和詞組有時(shí)難以記憶。英語網(wǎng)為大家整理了英語語法大全，希望對同學(xué)們的英語語法學(xué)習(xí)有所幫助。更多內(nèi)容盡在英語網(wǎng)。
一、引導(dǎo)原因狀語從句的從屬連詞
主要的有because, as, since, seeing (that), now (that), considering (that)等：
The woolly shrank because it was washed badly. 毛衣因洗得不得法而縮水。
I cant get to sleep because of the noise outside. 由于外面聲音嘈雜我睡不著。
Since [As] weve no money, we cant buy it. 由于我們沒錢，我們無法購買它。
Seeing that its raining, wed better stay indoors. 既然外邊在下雨，我們最好待在室內(nèi)。
Now that you are here, youd better stay. 你既然來了，最好還是留下吧(既來之，則安之)。
【注】除以上提到的大家比較熟悉的引導(dǎo)原因狀語從句的從屬連詞外，when有時(shí)也可引導(dǎo)原因狀語從句(when表示既然)：
I cant tell you when you wont listen. 既然你不想聽，我就不告訴你了。
二、關(guān)于 notbecause 結(jié)構(gòu)
該結(jié)構(gòu)中的否定詞有時(shí)否定主句，有時(shí)否定從句，一般要根據(jù)句子的意思作出正確或合乎邏輯的理解。若not否定主句，最好在because之前用逗號，否則會引起歧義，如下句在沒有特定上下文時(shí)就有兩種解釋：
I didnt go because I was afraid. 我沒有去是因?yàn)榕隆? 我不是因?yàn)榕虏湃ァ?/p>
不過若because之前有just修飾，一般認(rèn)為not 是否定從句的：
You shouldnt get angry just because some people speak ill of you. 你不要因?yàn)橛腥苏f你壞話而生氣。
三、because 習(xí)慣上不與 so 連用
漢語習(xí)慣上說因?yàn)樗?，但英語習(xí)慣上卻不能將 so 與 because 連用：
因?yàn)橄掠?，所以我們呆在家里?/p>
正：Because it was raining, we stayed at home. / It was raining, so we stayed at home.
誤：Because it was raining, so we stayed at home.
四、because 從句與 because of 短語的轉(zhuǎn)換
Because引導(dǎo)的原因狀語從句有時(shí)可與because of 短語轉(zhuǎn)換：
He cant come because he is ill. / He cant come because of his illness. 他因病不能來。
I said nothing about it because his wife was there. / I said nothing about it because of his wifes being there. 因?yàn)樗拮釉谀莾?，我對此事只字未提?/p>
