because前面要加逗号吗

2023-12-29 10:15 浏览

在使用"because"时,通常不需要在前面加逗号。逗号主要用于分隔句子中的不同部分,而"because"引导的从句是一个完整的句子,不需要被逗号分隔。然而,在某些情况下,可以使用逗号来强调从句或在句子中添加额外的信息。总的来说,逗号的使用与句子的结构和语境有关。

because前面要加逗号吗

加不加逗号取决于句子结构和语境。一般情况下,因果关系、转折关系、条件关系、对比关系等复杂的句子结构中,需要加上逗号以便于理解。

而简单的主谓结构中,则可以不加逗号。此外,因为常常涉及到语气的变化,在有些情况下,加上或省略逗号会对句子带来不同的语气效果。因此,在写作中,需要根据具体情况来判断是否需要加逗号,以使句子更加准确清晰。

1. She feels devalued because she knows her husband has had affairs.

她觉得自己掉价了,因为她知道丈夫有了外遇。

2. I denied my father because I wanted to become someone else.

我和父亲断绝了关系,因为我想成为一个不一样的`自己。

3. I get very nervous because I'm using a lot of expensive equipment.

因为正在使用很多昂贵的设备,所以我非常紧张。

4. Because you're not burning calories, everything you eat turns to fat.

由于没有消耗卡路里,你吃的所有东西都会变成脂肪。

5. He was not a particularly good shot because of his eyesight.

他视力不好,算不上是一个出色的射手。

because的用法

because的用法1:because的基本意思是“因为”,强调直接造成某种结果的理由和原因,所引导的原因状语从句多置于主句之后,有时为了强调,也可置于主句之前,并用逗号与句子的其他部分隔开。

because的用法2:because还可用来引导让步状语从句,这时,通常用于否定句或疑问句中。

because的用法3:because有时还可引导表语从句。

because的用法4:because可用于强调句。

because的用法5:not…because…结构有时否定主句,有时否定从句,须根据上下文正确判断。一般来说,否定主句时because前多有逗号,而如果because前有just,则多半否定从句。

because的用法6:because可用于省略句。

because使用注意事项

注意一: because除用于引导原因状语从句外,还可引出表语从句。如:

It is because he is too foolish.

那是因为他太蠢了。

It is because you're eating too much.

那是因为你吃得太多了。

注意二 : 汉语可以说“因为…所以 … ” 但是英语却不能使用because… so…这样的结构。改正的办法是,要么去掉其中的because,使之成为并列句;要么去掉so,使之成为主从复合句。如:

因为他很忙,所以不能来。

误:Because he is very busy, so he can't come.

正:Because he is very busy, he can't come.

正:He is very busy, so he can't come.

注意三 : 汉语说“之所以…是因为 , 说成英语通常是Thereason(why)is that 其中的that最好不用because代替。 如:

The reason (why) I'm late is that[because] I missed the bus.

我迟到的原因是因为我没有赶,上公共汽车。

注意四:在not…because…这一结构中,not 有时否定主句,有时否定从句,具体视语境而定。一般说来,若 not否定主句,最好在because之前用逗号,否则会引起歧义,如下句在没有特定,上下文时就有两种解释:

l didn't go because l was afraid.

a.我没有去是因为怕。

b.我不是因为怕才去。

但是若because之前有just 修饰,一般认为not是否定从句而不是主句。如:

You shouldn't get angry just because some people speak ill of you.

你不要因为有人说你坏话而生气。

注意五: 用于复合介词because of,其后可接名词、代词、动名词、what从句等。如:

He is here because of you (that)。

他为你(那事)而来这里。

We said nothing about it, because of his wife's being there.

因为他妻子在那儿,我们对此只字未提。

He left the company because of what the boss said at the meeting.

他离开了这家公司,是因为老板在会上讲的话。

但是, because of后不能直接跟that从句或者是没有引导词的从句。如:由于我的病我不能干这工作。

正:l can't do the work because of my illness.正: l can't do the work because I'm ill.

误:l can't do the work because of I'mill.

误:l can't do the work because of thatI'm ill.

because从句与because of短语的转换

Because引导的原因状语从句有时可与because of 短语转换,because of后加的原因可以为好或坏,但最正规的还是because。

(1)He can't come because he is ill./He can't come because of his illness.

他因病不能来。

(2)I said nothing about it because his wife was there./I said nothing about it because of his wife's being there.

因为他妻子在那儿,我对此事只字未提。
