主从复合句
要点:
1.主语从句作主语,主句谓语动词通常用 单数;为使句子平衡,常用it作形式主语。
2.表语从句还可以用as if, as though引导。
3.表示“是否”,引导宾语从句时可用if或 whether,但在介词后或直接与or not连用时, 只能用whether引导;引导表语从句、同位 语从句或位于句首的主语从句时,只 能用whether,不用if。
8.what可引导名词性从句但不能引导定语 从句。what引导名词性从句,有时相当于 “the +名词+that”,表示“(所)……的”。 如:
What(=The thing that) you said was right. 你所说的是正确的。

What worries my classmate Mary a lot these days[1] is that she puts on too much weight and she is frequently ill[2]. She has some doubts whether she eats too much fast food high in fat or sugar[3]. Also, with the college entrance examination approaching, she becomes more stressful and she couldn’t sleep well these days. Maybe this is also the cause that she becomes fatter these days[4], she thinks. How she becomes slimmer and healthier[5] has been her main task.
1. 在时间状语或条件状语从句中,通常用一 般现在时代替一般将来时,用现在完成时代 替将来完成时。
2. 辨析:when, while, as引导时间状语从 句。while必须与延续性动词连用,强调主句 动作延续到从句所指的整个时间时,只能用 while;表示“随着” 只能用as;表示有规律 的“每当” 时或主句动作与从句动作有先后 时,只能用when。
we are in a great hurry. That’s true. We should mind our step so that[20]we can
ensure our safety.
汉语译文:我妈妈在厨房做饭,而我在做作 业。我一做完作业就去拿水喝,这时门铃响 了。然而,我还没来得及打开门,我的妹妹 就用钥匙打开了门。我们看见她时,非常惊 讶,因为她的衣服和脸非常脏。她看起来比 我们预料的更可怜。因为我们不知道发生了 什么事,我们站在那,等着我妹妹说她的故 事。除非我妹妹告诉我们有关的一切,否则 我们是不会离开的。
4. as引导让步状语从句时,从句中的状语、 表语或动词必须置于句首;though引导让 步状语从句时,这些成分可置于句首也可 用正常语序;但although等其他词引导的 让步状语从句不能将这些成分前置。
5. 表示“虽然” 的连词不能与表示“但是” 的连词but连用; 表示“原因” 的because 等连词不可与表示结果的连词so等同时使 用。
3. 辨析:because,since, as引导原因 状语从句。because语气最强,表示直接 的原因,是说话人认为对方不知道的原
因,它引导的从句通常位于主句之后; 在回答why时,或者在强调结构中,只 能用because。since和as是对大家已知的 事实提供理由或背景,它们引导的从句 多位于主句前,有时也位于主句后。
