的谓语只能 用肯定式。 unless和 if…not同义, unless是书 面语, if…not是口 语,通常二 者可以换用。 条件状语从 句中的谓语 动词的时态 一般要用现 在时或过去 时代替一般 将来时或过 去将来时。

a country that is home to one fifth of mankind. (2000全国)

A 2、 It is known to all that _____ you exercise regularly, you

as long as 与 as far as 都可引导条件状语从句,as long as 表示“只要…”,as far as 表示“就…而论

(而言)”。题1根据题意应该选用B。in case 表示 “以防”,根据题2的句意,不难作出选择。

though although

Although (Though) he was over sixty, (yet) he began to learn French.

1. 在句子中一般用

虽然他六十多岁了,但仍开始 学习法语 。
We were not tired though (although) we had worked all day.

了“虽然”就不 能再用“但是” (but)但可以与 yet或still连用。
2. though / although

虽然我们干了一天活,但并不 累.
even if even though

意义相同,用法 基本一样,前者 通俗,口语化, 后者正式多放主 句的前面。
even if 和even though

I’ll go even if (though) it rains tomorrow. 即使明天下雨,我也要去。

的意思为“即 使”“纵使”有 退一步设想的意 味,多用于书面 语中。


从属连词 as

让 步 状 语
no matter (who, what when, where which, how…)

Child as he is , he knows a lot . 虽然他是一个孩子,但他懂得很多。 Cold as it is, (= Though it is cold,)the children play outdoors. 虽然天气冷,但孩子们仍在户外玩。
Do it no matter what others say. 不管别人怎么说,尽管干。 No matter how busy he was, he studied English every day. 不管他多忙,他都每天坚持学习英语。 No matter who takes up the matter for me ,I shall be very grateful. 不管谁为我处理这件事,我都将非常感激。

as引出的状语从句多用于 书面语,它比用 though或although引导的 从句,语气强,更有表 现力,从句常放在句首 ,语序部分倒装。 no matter……与 who-ever 引导的让步状语从句意 义基本一 样,no matter……引导的从句 可是以位于主句前或主 句后。

wh-ever (whatever whoever whenever Whichever however)

Whatever happens / may happen , we shall not lose heart. 无论发生什么,我们都不要失去信心。 Whoever comes, he will be welcome. 无论谁来,都会受到欢迎。

1. Wh-ever从句中的动词有 时可以和may连用。 2. 判断wh-ever引导的是状 语从句还是名词性从句 的一点是: 名词性从句, 主句中一定有一个成分 要在从句担任,一般从 句与主句之间没有逗号。 不可将no matter与whever连用

问题1: 1、 _____ I accept that he is not perfect, I do actually like the A
person. (04江苏)
A. While B. Since C. Before D. Unless 2、Allow children the space to voice their opinions, ____they B

are different from your own. (05湖南卷)(B)
A. until B. even if C. unless D. as though

while 是高考中的高频词,它既可引导时间状语从句,又可 引导并列句,还可引导让步状语从句,表示“尽管”。 even if 等于 even though,表示“即使、尽管”。as though 等于 as if,引导方式状语从句,表示“好像、似 乎”。

1. He tried his best to solve the problem, ___ difficult it was. A
(05天津卷) A. however B. no matter C. whatever D although 2、 2. The old tower must be saved, ______the cost. (05浙江) B A.however B.whatever C.whichever D.wherever no matter wh- 与 wh-ever 的联系及区别: no matter wh- 只引导让步状语从句,此时与 wh-ever通用。 如: No matter when / Whenever he comes back, he should be invited to the party. wh-ever又可引导名词性从句, No matter wh-不能。如: Whatever I can do for you will be nothing but paying a debt. Whoever can help us will be welcome
