Question

【题目】–Do you know his number?

-No, I even have quite enough trouble______ my own.

A. remember B. to remember

C. remembered D. remembering

Answer 1

【答案】D

【解析】

试题分析：考查动词时态和语态。句意：——你知道他的号码吗？——不知道，我甚至记自己的号码都有困难。固定搭配have difficult/trouble doing sth表示“做....事情有困难”，所以这里remember应该用动名词形式，故选D。
