语法：原因状语从句和because of的用法

(1). Since no one else saw these aliens, I refuse to believe you.. (2). We went there because I heard a loud noise last night. (3). I’m unhappy because of your marks in the exam!

句子（1）中含有since引导的原因状语从句，句子（2）中含有because引导的原因状语从句，句子（3）中含有because of短语。

1.because,as,since这几个词都表示“因为”，语气由强到弱依次是because>since>as，这几个词都是从属连词。

(1)because表示直接原因，它所指的原因通常是听话人所不知道的，其语气最强。常用来回答 why所提出的问句，一般放在主句之后，也可以单独使用。 I stayed at home because it was raining. (2)since侧重主句，从句表示仙人的或已为人所知的理由，常常翻译为“既然”，语气比because 稍弱，通常位于句首。 Since every is here, let’s start.

(3)as是常用词，它表示的是双方已知的事实或者显而易见的原因。含义与since相同，但语 气更弱，没有since正式，常翻译为“由于、鉴于”，从句说明原因，主句说明结果，主从 并重。

We all like her as she is kind.

2.because of是介词短语，其后可接名词、代词或者动名词以及由关系代词引导的从句。 He lost his job because of his age.
