今天进入第十七讲——中考最常考的6组连词辨析(二)。
在第九讲中,我们已经搞定了连词的基础分类(并列连词、时间/条件状语从句、原因/结果/让步连词)。今天继续攻克连词家族中最容易丢分的六组辨析:
when/while/as、because/since/as/for、if/whether、so...that/such...that、although/though/even if、并列连词短语的就近原则。
这几组连词,几乎每年中考都会在单选、完形和语法填空中出现。它们翻译成中文意思都差不多,但用法天差地别。今天一次性讲清楚,背完直接拿分!
一、when / while / as——“当……时”三兄弟 ★★★★★
这是中考出场率最高的连词辨析,没有之一。
| when | He came in when I was reading. | |
| while | I was reading while he was sleeping. | |
| as | As I grew older, I became more interested in English. |
速记口诀:
when接短暂,while接持续,as强调同时/随着。
⚠️ 中考最高频考点:
- when
后面可以接短暂性动词,也可以接持续性动词。 - while
后面只能接持续性动词,且常用进行时。 - as
常表示“一边……一边……”或“随着……”。
真题实战(2025·中考真题改编):
I was doing my homework ______ my mother was cooking.
A. when B. while C. as D. before
答案:B解析:两个动作同时进行,且都是持续性动词→用 while。
二、because / since / as / for——“因为”四兄弟 ★★★★★
| because | I stayed home because it rained. | ||
| since | Since you‘re here, let’s start. | ||
| as | He didn‘t come as he was busy. | ||
| for | He must be ill, for he didn’t come. |
速记口诀:
because最强答why,since既然已知,as由于附带,for补充放后。
⚠️ 易错提醒:
- because
和 so 不能同时用! - for
是并列连词,表示“因为”时不能放句首,前面通常有逗号。
真题实战(2024·中考真题改编):
______ you are tired, you should have a rest.
A. Because B. Since C. As D. For
答案:B解析:“既然你累了,就应该休息”→ Since 表示“既然”。
三、if / whether——“是否”两兄弟 ★★★★★
| if | I don‘t know if he will come. | |
| whether | I don’t know whether he will come or not. |
⚠️ 只能用 whether 的四种情况:
和 or not 直接连用:whether or not 作介词宾语:It depends on whether you like it. 后接不定式:whether to go 引导主语从句放句首:Whether he will come is unknown.
速记口诀:
if条件/是否,whether是否更正式;or not、介词后、不定式前,只能用whether。
真题实战(2025·中考真题改编):
I don‘t know ______ he will come or not.
A. if B. whether C. that D. what
答案:B解析:和 or not 连用→只能用 whether。
四、so...that / such...that——“如此……以至于” ★★★★★
| so + 形容词/副词 + that | He is so young that he can’t go. | |
| such + 名词短语 + that | She is such a kind girl that everyone likes her. |
速记口诀:so形副,such名。
⚠️ 特殊结构:
- so + many/much/few/little + 名词 + that
:so many students that... - such + a/an + 形容词 + 单数名词 + that
:such a kind girl that...
真题实战(2024·中考真题改编):
He is ______ young ______ he can‘t go to school.
A. so; that B. such; that C. too; to D. enough; to
答案:A解析:young 是形容词→用 so...that。
五、although / though / even if / even though——“虽然/即使” ★★★★☆
| although / though | Although he is tired, he keeps working. | |
| even if / even though | I will go even if it rains. |
⚠️ 中考最高频陷阱:although / though 和 but 不能同时用!
❌ Although he is tired, but he keeps working. ✅ Although he is tired, he keeps working. 或 He is tired, but he keeps working.
速记口诀:although/though,but不同用;even if/even though,即使也不怕。
真题实战(2025·中考真题改编):
______ he is young, he knows a lot.
A. Although B. But C. Because D. So
答案:A解析:表示“虽然……但是……”→用 Although,不能再用but。
六、并列连词短语的就近原则——both...and / either...or / neither...nor / not only...but also ★★★★★
| both...and... | 复数 | Both Tom and Jerry are good friends. | |
| either...or... | 就近原则 | Either you or he is wrong. | |
| neither...nor... | 就近原则 | Neither he nor I am right. | |
| not only...but also... | 就近原则 | Not only the students but also the teacher is happy. |
速记口诀:both and复,either or就近,neither nor就近,not only but also就近。
真题实战(2025·中考真题改编):
—Which do you prefer, tea or coffee?—______ is OK. I don‘t mind.
A. Both B. Either C. Neither D. All
答案:B解析:两者中任何一个都可以→ Either。
