中考網(wǎng)整理了關(guān)于2021年中考英語(yǔ)連詞的用法總結(jié),希望對(duì)同學(xué)們有所幫助,僅供參考。
連詞的用法
連詞的功能
用來(lái)連接詞,短語(yǔ),從句或句子的詞叫連詞。連詞是一種虛詞,在句中不能單獨(dú)使用。連詞可分為兩類:并列連詞和從屬連詞。
并列連詞
并列連詞用來(lái)連接具有并列關(guān)系的詞,短語(yǔ)或句子。常見(jiàn)的并列連詞有:
(1)表并列關(guān)系的and, both…and, not only…but also, neither…nor等。
(2)表選擇關(guān)系的or, either…or等。
(3)表轉(zhuǎn)折關(guān)系的but, while等。
(4)表因果關(guān)系的for, so等。
從屬連詞
從屬連詞用來(lái)引導(dǎo)從句。常見(jiàn)的從屬連詞有:
(1)引導(dǎo)時(shí)間狀語(yǔ)從句的after, before, when, while, as, until, till, since, as soon as等。(2)引導(dǎo)條件狀語(yǔ)從句的if, unless等。
(3)引導(dǎo)原因狀語(yǔ)從句的because, as, since等。
(4)引導(dǎo)目的狀語(yǔ)從句的so that, in order that等。
(5)引導(dǎo)讓步狀語(yǔ)從句的though, although, even if等。
(6)引導(dǎo)結(jié)果狀語(yǔ)從句的so that, so…that, such…that等。
(7)引導(dǎo)比較狀語(yǔ)從句的than, as…as等。
(8)引導(dǎo)名詞從句的that, if , whether等。
常用連詞的用法辨析
。1) while, when, as
這三個(gè)連詞都可引導(dǎo)時(shí)間狀語(yǔ)從句,但用法有所不同。
1) 當(dāng)某事正在進(jìn)行的時(shí)候,又發(fā)生了另一件事。While, when, as 都可用來(lái)引導(dǎo)表示“背景”的時(shí)間狀語(yǔ)從句。例如:
As/When/While I was walking down the street I noticed a police car.
2) 當(dāng)兩個(gè)長(zhǎng)動(dòng)作同時(shí)進(jìn)行的時(shí)候,最常用的是while。例如:
While mother was cooking lunch, I was doing my homework.
3) 當(dāng)兩個(gè)動(dòng)作都表示發(fā)展變化的情況時(shí),最常用的是as。例如:
As children get older, they become more and more interested in things around them.
4) 當(dāng)兩個(gè)短動(dòng)作同時(shí)發(fā)生時(shí),或表示“一邊…一邊…”時(shí),最常用as。例如:
Just as he caught the fly, he gave a loud cry.
She looked behind from time to time as she went
5) 當(dāng)從句的動(dòng)作先于主句的動(dòng)作時(shí),通常用when。例如:
When he finished his work, he took a short rest.
6) 當(dāng)從句是瞬間動(dòng)作,主句是延續(xù)性動(dòng)作時(shí),通常用when。例如:
When John arrived I was cooking lunch.
。2)as, because, since , for
這四個(gè)詞都可表原因,但用法有區(qū)別。
1) 如果原因構(gòu)成句子的最主要部分,一般用because。因此,because引導(dǎo)的從句往往放在句末。例如:
I stayed at home because it rained.
---Why aren’t you going?
---Because I don’t want to.
2) 如果原因已被人們所知,或不如句子的其它部分重要,就用as或since。Since比as稍微正式一點(diǎn)。As和since 引導(dǎo)的從句一般放在句子的開(kāi)頭。例如:
As he wasn’t ready, we left without him.
Since I have no money, I can’t buy any food.
