傲世皇朝平台-原因状语从句加不加逗号

原因状语从句

应该用can’t，这是将来时态，不能用couldn't

常用来引导原因状语从句的从属连词有：because、as、since、for。

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：now (that)、when、seeing (that) 、considering (that)、given (that)、in that、for the reason that等。

because的用法

because引导的原因状语从句一般放于主句的后面。当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。如：

从句在后（有逗号）：We didn't go for an outing last Saturday, because it was raining hard the whole day.

从句在后（无逗号）：We didn't go for an outing last Saturday because it was raining hard the whole day.

从句在前（必须有逗号）：Because it was raining hard the whole day, we didn't go for an outing last Saturday.

because用在句中，要不要加逗号

加不加逗号都可以，没有任何区别。但一般写作最好不用逗号隔开，除非because放在句首，后面的句子要用逗号隔开。

because从句可放在主句前或主句后，更常用于主句后。放在主句前时，通常要用逗号与主句分开；放在主句后时，则不需要逗号。例如：

He was ill because he drank too much wine.

=Because he drank too much wine, he was ill.

因为他喝太多酒，所以生病了。

扩展资料：

because是从属连词，引导的原因状语从句指的是自然、直接的原因，主句表示必然的因果关系，而原因构成句子的主要部分，是句子的重点。另外，because引导的从句多放在句末，但有时也可放在句首，这种情况往往是为了强调。

如果原因很明显或已为人们所知，或不如句子的其余部分重要，就用as或since，since比as更正式一些，这两个词都为从属连词，常译为“由于，既然”，语气比because轻。

because前面要加逗号吗

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。
