Question

A didn't go to the party not _(because/because of)the weather but _(because /because of)busy doing

请说明理由，急。。。！！！谢谢^_^
Sorry题目后部分是but_he didn't feel well.能补充回答吗!

Answer 1

答案：because of, because.

解释：because of和because区别如下：
1. because of视为一个介词，其后加名词/代词/动名词（短语）；
而because是一个连词，后面引导一个成分完整的原因状语从句（有自己的主谓宾语等）。
2. 第一空后面，the weather就是一个名词短语“天气”，所以用介词短语because of；
而第二空后，he didn't feel well就是一个完整的句子，所以用连词because.

Answer 2

because of because

Answer 3

because of, because of

只有当后面是完整的句子时，才用Because，其余一律用because of

Answer 4

because of the weather
but because of busy doing
because of 介词后面接名词作宾语。
because后面只能接原因从句

Answer 5

because of 因为它加名词、代词、动名词
because 因为它接一个句子

Answer 6

都是BECAUSE OF
