Now that the new machines have been bought,________will you do with these old___________?
a.what;one；b.what;one's；c.how;one；d.how;one's这道题中will you do with these old___________?是主语从句吗?那为什么用what?how不是也可以引导主语从句的吗?
答
what是疑问句,不是主语从句.What he will do with the book is still not known.这就是主语从句.what will you do with these old ones答案是B, 但第二个不对,应该用ones意思是will you do what with the old ones你...不是how to do后面要加宾语，what to do 后不加宾语吗？how to do要加宾语但how to deal就不加了what to do中what是宾语，所以，不加宾语了。
