because+句子
because of+名词
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,如果没有则是断语。
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。
