问题描述:

i want to have a holiday .it is _the doctor says i need a good rest.用because

不能用,大大的错误!!

对的
the doctor says i need a good rest句子已经完整
这个句子应该是it is because (that)the doctor says i need a good rest.

不对, 这里不能用 because.
I want to have a holiday. It is what the doctor says I need a good rest.
我想要放个假. 那是医生说我需要好好休息.
