because

as

since 

因为，由于

because 

口语和写作时都非常常用。Because侧重于强调原因。

She spoke quietly because she didn't want Lucy to hear. 她说话很轻，因为不想让露西听到。

spoke 说话，讲话，原形是speak

quietly 安静地，轻声地，小声地

如果想加强强调原因，可以把because从句放到句子前半，加上逗号（because从句和后面句子之间需要逗号）

Because she didn't want Lucy to hear, she spoke quietly.

因为她不想让露西听到，所以说得很小声。

Because从句也可以单独用：

A：She spoke too quietly. 她说得太小声了。

B：Because she didn't want Lucy to hear. 因为她不想让露西听见。

另外（also），because在非正式的口语和写作时，可以缩写成 cos。

I'm laughing cos I'm so happy. 我笑是因为我很高兴。

as 和 since

侧重于强调结果（“所以”后面的内容），而不是原因。除此之外（also），as和since比because要更正式。

You can go first as you're the oldest.

你可以第一个去，因为你年纪最大。

They're very expensive, since they're quite hard to find.

它们很贵，因为很难找到。

最后，如果要讲带有因为从句的疑问句，这时只能用because，而不用as或since。

Are you feeling unwell because you ate too much?

你是不是因为吃得太多而感到不舒服？

！！不说Are you feeling unwell since/as you ate too much?！！
