because 和because of的区别，我有点分不清楚

because和because of

because是连词，其后接原因状语从句或回答以why开头的问句；

而because of是复合介词，其后接名词、代词或动名词，或者what引导的名词性从句。

如

(1)___he is ill,he is absent today.

(2)He is not at school___his illness.

(3)He can”t come___the heavy rain.

(4)We like physics___we can learn a lot
of ideas.

答案：1.Because 2-3.because of 4.because

because,because of以及since 都有“因为”的意思，但也有区别：
because of 后面加名词或名词短语
because和since 后面加句子

because of跟名词，because跟从句
