Question

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

A. is doing my homeworkB. am doing my homework

C. is doing our homeworkD. are doing our homework

 

Answer 1

D

【解析】

试题分析：句意：现在八点了，我妈妈正在读书，我和妹妹在做作业。my sisterand I 是两个人，be 动词用are,do one’s homework中的one’s根据主语进行变化，故选D。

考点：考查主谓一致及固定搭配。
