中考考点
1.并列连词and, but, so, or等的主要用法。
2.常用的从属连词的基本用法。
连词是一种虚词,用于连接单词、短语、从句或句子,不单独用作句子成分。连词按其性质可分为并列连词和从属连词。常见考点如下:
专题7 连词
1 并列连词的用法
1.表并列关系
表示并列关系的并列连词有and(和), neither…nor… (既不……也不……), not only…but (also)……(不仅……而且……), both…and…(……和……都), as well as(而且)等。如:
_________ you ______ I am right.
你和我都不正确。
Neither

[提醒] (1)both…and…意为“……和……都”,连接两个成分作主语时,谓语要用复数形式。
(2)neither…nor…意为“既不……也不……”; not only… but (also)…意为 “不但……而且……”;either…or…意为“或者……或者……”。它们连接两个成分作主语时,其谓语通常与靠近的主语保持一致,即遵循“就近原则”。
(3)as well as意为“而且,还,又”,连接并列主语时,谓语动词应与它前面的主语一致。
2.表转折关系
表示转折关系的并列连词有but, yet, while, however (都意为“但是,然而”)等。如:
I failed again, ______ I won't give up.
我又失败了,但我不会放弃的。

7.引导比较状语从句的连词: than (比), as…as… (和……一样……), not as/so…as(……不如……)等。如:
I think English is as important as maths.
我认为英语和数学同等重要。
[提醒](1)以if引导的条件状语从句和as soon as, when引导的时间状语从句遵循“主将从现”的原则。

3 引导宾语从句的从属连词
1.that引导陈述句作宾语从句。如:
He told me that he would move to Japan the next year. 他告诉我明年他将搬到日本。
2.if/whether引导一般疑问句作宾语从句。 如:

专题7 连词
3.wh-疑问词引导特殊疑问句作宾语从句。如:

(2)if/whether 意为“是否”。
(3)在if/whether以及wh- 疑问词引导的宾语从句中,引导词后面要用陈述语序。
专题7 连词
4 易错分析
1.关于not…until
(1)He stayed there until it was very late.
他在那一直待到很晚。
句中stay是延续性动词,所以不用not。
(2)He didn't leave until it was very late.
直到很晚他才离开。
句中leave是非延续性动词,所以用not。
专题7 连词
2.or还是and
“祈使句+or+陈述句”结构中,or前后两部分是对立的; “祈使句+and+陈述句”结构中,and前后两部分是统一的。(or或and后的陈述句,常用一般将来时) 如:
Study hard, ____ you won't pass the exam.
努力学习,否则你不会通过考试。
Study hard, ______ you will pass the exam.
努力学习你就会通过考试。
专题7 连词
or
and
两句都可以转换成“If条件句+主句”形式,此时要去掉or和and。如:
If you don't study hard, you won't pass the exam.
如果你不努力学习,你就不会通过考试。
If you study hard, you will pass the exam.
如果你努力学习,你就会通过考试。
专题7 连词
3.when还是while
(1)when意思是“在……时刻或时期”,它可以兼指“时间点”与“时间段”,从句的动词既可以是延续性动词也可以是非延续性动词。 如:
When I got home, he was having supper.
当我到家时他正在吃晚饭。
(2)while只指“时间段”,不指“时间点”,从句的动词只限于延续性动词。 如:
While I slept, a thief broke in.我睡觉时一个小偷进来了。
