homework done on time will lead to better grades
问题描述:
homework done on time will lead to better grades
这里怎么只能用done,用be done 不行么,这句话的句子成分是怎样的.homework done on time做主语么
答
这是定语从句 初三才学 done on time 用来修饰homework
homework( (that)done on time) will lead to better grades
homework done on time是个名词短语 是主语 ,如果加be 就成一个句子了.
