It is no good()the students()homework all day long.
A.to have.,.done B.to have...to do
C.having...doing D.having...done
选C
前面是一固定搭配，it is no good doing sth意思是干什么没好处
后面是have sb doing sth让某人一直干某事。
选C. It is no good/use+doing stn. 做...是没有好处/用处的
have sb. do sth. 是让某人做某事,但是all day long 表示一整天,所以用have sb. doing sth. 表示让某人一直做某事. 如:Don't have him doing homework all day. 不要让他整天做作业.
另外have sth. done 表示让别人将某事完成. 如:I'll have my hair cut. 我要去理发(让别人理)
it is no good doing sth
it is no use doing sth 名词性从句.
the students()homework 学生自己可以作用主动语态.
所以选C
A
no good to do sth. 做...没益处
have sb. done. 让某人做
C
前面用to have or having 都行
后面就必须要用doing了
选A的
