Answer 1

【答案】C

【解析】句意：當(dāng)他們的母親進(jìn)來(lái)的時(shí)候，Judy和她的弟弟正在玩電腦游戲。這里是when引導(dǎo)的時(shí)間狀語(yǔ)從句，當(dāng)某個(gè)動(dòng)作發(fā)生的時(shí)候，某個(gè)動(dòng)作正在進(jìn)行，從句是一般過(guò)去時(shí)態(tài)，主句用過(guò)去進(jìn)行時(shí)，其結(jié)構(gòu)是be doing的形式，主語(yǔ)是Judy，with her brother在這里是介詞短語(yǔ)做伴隨狀語(yǔ)，這里的be動(dòng)詞用was，根據(jù)題意，故選C。
