原因状语从句怎么用?

1、because引导的原因状语从句一般放于主句的后面,because从句位于句首时要用逗号分开,放在句末 时,可不用逗号分开。because表示直接原因, 语气最强, 最适合回答why引导的疑问句。

例如:I do it because I like it。

我做这件事是因为我喜欢。

2、since引导的原因状语从句一般放于主句之前表示已知的、 显然的理由(通常被翻译成“既然”), 较为正式, 语气比because弱。

例如:Since you are free today, you had better help me with my mathematics。

既然今天你休息, 你最好帮我补习数学。

因为下雨,所以我们得呆在家里。

正:Because it was raining,we stayed at home。

误:Because it was raining,so we stayed at home。

原因状语从句是什么

原因状语从句是状语从句中较为简单的一种,是用于解释事件发生原因的状语从句,引导原因状语从句的从属连词有because, as, since, considering (that), given (that)等。 扩展资料

1、because的缺困用法:because通常表示直接的原因。because引导的从句表示直接而明确的原因和理由,表示按因果关系的推断,语气很强,用来回答why的问题,一般位于主句之后。eg. We couldn't go out because these robber are still outside.

2、for的用法:for是并列连词,引出的原因较间接,似乎是事后所想到的.补充解释的理由,只陈述一般推断的理由,不一定表示产生结果的必然原因,主要放在两伏带念个并列句之间。eg. It must be raining for lots of people running on the street.

3、as和since的用法:表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显,或已为听话人所熟悉。since要比as正式一些,它们通常被置于语句之前。

4、now that(既然)的用法:now that同since相似,语气较弱,强调人们已知的事实。eg. Now that you are busy, you can give up this trip. 既然你很忙,你可以不去这个旅行。

5、because, since, as和for的比较① because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或 since。② 由because引导的从句如果放在句末,且前面有逗号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就行激只能用for。③ 用于强调句型时和被not所否定时都只能用because。

原因状语从句

应该用can’t,这是将来时态帆指大,不能用couldn't

除此之外,还有一些其实也较为常见但对于不少基础阶段的英语学习者来说不太熟悉的连接词语,如:逗谈now (that)、when、seeing (that) 、considering (that)、given (that)、in that、for the reason that等。
