Question

选择题you can't imagine the difficulty the man has____because he doesn't speak much Putonghua

A、communicating B、comunicated c、to communicate d、communicate

Answer 1

A have difficulty doing sth
如果做后置定语原句应该是：you can't imagine the difficulty to communicate the man has because he doesn't speak much Putonghua.
这里可以这样理解：the difficulty后省略了定语从句引导词：which/that 把difficulty带到从句中 就是the man has difficulty...所以根据固定搭配答案是communicating

Answer 2

选A，have/has difficulty （in）doing sth。the man has 作difficulty 的定语从句。

Answer 3

B，这是个完成时的句子，很简单呀

Answer 4

还原法：you can't imagine the man has difficulty in communicating ...选A

Answer 5

A 只是一个短语 have difficulty in doing
