问题描述:

Do you think you have paid enough attention to ___ your spoken English?
A.improve
B.improved
C.improves
D.improving

pay attention to doing
look forward to doing

A
to是动词不定式的标志,后面跟动词原形啊,因此用improve(动词原形)

pay attention to 固定短语,注意---,花精力做----
这边的to是介词哦,后面接动名词,所以选择D. improving
希望能帮到你

D attention to doing sth
