—Do you have difficulty working out the problem?

—Yes. It is me.

A. no; easy for

B. some; within

C. any; within

D. any; beyond

答案：

A. no; easy for

B. some; within

C. any; within

(答案→)D. any; beyond

解析：问“有没有”，用any；beyond sb. 指超出某人的能力范围，与too hard / impossible for sb. to do sth. 相当。另外，要注意：答案A是按中国人的思维方式设计的题目，千万不要上当；因为用yes回答，不管怎么问都是指“有”困难，这就与后文的easy for me相矛盾了。
