A. or B. but C. and
4)表示因果關(guān)系的并列連詞有:so, for, therefore等。
注意:
for和because在表示“原因”時(shí)意思基本相同,一般可以互相代用。because引導(dǎo)的從句一般放在主句后,有時(shí)也可放在主句前,而for引導(dǎo)的句子只能放在主句后。另外
從屬連詞
1)引導(dǎo)時(shí)間狀語(yǔ)從句的從屬連詞有:when,while,as,after,before, since, until, as soon as等。
注意:
【例句】

注意:
Since用于現(xiàn)在完成時(shí)
Not until位于句首要倒裝
as soon as引導(dǎo)的時(shí)間狀語(yǔ)從句,遵循主將從現(xiàn)的原則

注意:
if
易錯(cuò)點(diǎn):
在否定句中,并列結(jié)構(gòu)用or連接,但含有兩個(gè)否定詞的句子實(shí)際上被看作是肯定結(jié)構(gòu),要用and連接。
3.because“因?yàn)?rdquo;,so“所以”不能同時(shí)出現(xiàn)在同一個(gè)句子中,只能用其一。(al)though“雖然”,but“但是”也不能同時(shí)出現(xiàn)在同一個(gè)句子中。
4.句型both...and的用法連接主語(yǔ)時(shí)謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式。
句型
①連接兩個(gè)成分,其謂語(yǔ)動(dòng)詞根據(jù)就近原則,與所靠近的成分保持?jǐn)?shù)的一致。
②
not only…but also…可以連接兩個(gè)句子,not only位于句首時(shí),not only后的句子要倒裝。
句型
either...or...,neither...nor...連接主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞也采用就近原則。
