改同义句:My mother was very angry with me,for I didn't finish my homework.

问题描述:

改同义句:My mother was very angry with me,for I didn't finish my homework.
My mother ----- ---- ---- me----- I didn't finish my homework.
was mad at;后面for还是because呢?

是Because.
“I didn't finish my homework” 是一个句子,后面加从句的一定要用because.
如果是My mother was mad at me for my homework.此时就只能用for.
