问题描述:

He did ________he could _______me with my maths.
a.what, to help b.that,help c.which, to help d.what, help

选A what he could作did的宾语,to help不定式表目的

答案是d.waht,help
He did what he could help me with my maths.
首先排除A和C,因为could 后面要加动词原形。
that 引导的是从句,而上面这句明显后面不是从句。
所以选what.

正确的是:A 其中he could为插入语,不用管它.而to 表目的

D因为could后接动词原形!

A
