Question

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

A．is doing my homework	B．a(chǎn)m doing my homework
C．is doing our homework	D．a(chǎn)re doing our homework

Answer 1

D

試題分析：句意：現(xiàn)在八點了，我媽媽正在讀書，我和妹妹在做作業(yè)。my sisterand I 是兩個人，be 動詞用are,do one’s homework中的one’s根據(jù)主語進行變化，故選D。
