Question

It’s 8 o’clock. My mother is reading a book. My sister and I _____.

A. is doing my homework B. am doing my homework

C. is doing our homework D. are doing our homework

 

Answer 1

D

【解析】

试题分析：句意：现在是8点，我的妈妈正在读书，我和我的姐姐正在做作业。根据It’s 8 o’clock可知这里指的是8点的时候，某人正在做某事。故用现在进行时，这里句子的主语My sister and I是两个人是复数，所以谓语动词用复数，故选D。

考点：考查动词时态。
