英语语法问题（很简单）
这题错了没?
He thinks play football is exercise.
答
he thinks that playing football is an exercise
答
playing.
答
这是宾语从句 从句是play football is exercise. 当然这里动词不能做主语，应将play football 改成playing football 。
答
playing作主语
答
应该是playing.
答
"play football is exercise."
是think的宾语从句
所以 要用现在分词,playing.
然后,伱的is,exercise,也错了...
