A,of disabed people getting B,of disabled people to get C,for disabled people getting .Dfor disabled people to get请教下老师们,为什么选D,而选C,
答案
选D
it是形式主语,后面要求用不定式或者that引导的从句表示出真实主语.原来的形式是it is adj for sb to do sth:it is difficult for disabled people to get good jobs,此处how difficult提前作为从句引导词了.
C是ing形式,所以不行 .
