Havinhg been ill in bed for nearly a month, he had a hard time ______ the exam.
A pass B to pass C passed D passing
这里为什么选D啊,D在这里作什么成分呢

Answer 1

人家都说答案是D了地说..
have a hard time doing （做某事有困难）相当于：have trouble doing sth.

而"have a hard time to do"是错误的，没有这个表达法。
这里是固定搭配哦~！

Answer 2

B

Answer 3

这个属于have+(adj.)+time+doing sth.

Answer 4

have a hard time doing （做某事有困难）
= have trouble/difficulty （in)doing sth
所以是D
