不太明白.别人给我讲说,如 he did what he can to help the poor(他尽其所能帮助穷人,what he can宾语从句,后面的to do 是目的状语.请问can后面的动词do呢?

句子结构是:Students ——主语;
(should do everything )(they can)——动宾+定语,意思是:任何他们能做到的事;
to improve their study——目的状语,意思是:以提高他们的成绩.
“they can”修饰的是everything,做定语
所以to do不是接在can后面,而是接在everything 后面的~去掉修饰的定语就好理解了:
Students should do everything to improve their study.
如有帮助请采纳~O(∩_∩)O~

Students should do everything (they can) to improve their study.
they can 可以看作是插入语,其实是定语,can后面的动词do 与前面的do重复,故省略了。

can 后面的动词就是前面的那个do
本来应该是student should do everything they can do to improve…,为避免重复,后面那个do就省掉了!
to improve是目的状语!

they can 作everything的定语从句,相当于修饰它,并且they can 后面省略了do,该句的意思是学生应该做任何他们能做的事来提高他们的学习成绩,所以后面的是目的状语从句,不定式表目的,所以选B
