老师请问 because和because of的用法有何区别?

ecause+从句

because of+名词

because 后边要接一个完整的句子

because of 后边一定要接一个不是句子的句子（短语）

判断断语还是句子的标准：

单独取出because或because of的内容,如果有动词（也就是谓语）的是句子,

如果没有则是短语.

例如：I didn't go to school because i am ill. am是谓语（动词）
I didn't go to school because of my illness. my illness是短语（名词）
分析：
I love you not because of who you are but because of who i am when i am with you.
are和am是谓语,所以不能用because of,只能用because.
