问题描述：
when the teacher came in,the students were doing homework.的同义句,用while来改!
答
when the teacher came in, the students were doing homework。
=The students were doing homework while the teacher was coming in.
用while来改前后动词必须是ing形式，不能不改原句，意思没有变就行了，同义句嘛。

您好！
1楼的错误！
When the teacher came in, the students were doing homework.
=The students were doing homework while the teacher was coming in.
答
while the students were doing homework,the teacher came in.
不要听楼下地胡扯.我们两个地回答可以算对.但是二楼的修改原句了,这种情况容易被扣分
