Question

17．
homework，last night
He was doing homework at 9 o'clock last night．．

Answer 1

分析 昨晚上9點(diǎn)他正在做作業(yè)．

解答 答案：He was doing homework at 9 o'clock last night．根據(jù)圖片結(jié)合提示詞可以得到的信息有：主語(yǔ)為he，動(dòng)詞短語(yǔ)為do homework，時(shí)間為昨晚九點(diǎn) at 9 o'clock last night．根據(jù)時(shí)間可判斷本句的時(shí)態(tài)為過(guò)去進(jìn)行時(shí)（was/were+doing）．句意為：昨晚9點(diǎn)他正在做作業(yè)．主語(yǔ)he為第三人稱(chēng)，故謂語(yǔ)動(dòng)詞用was．故答案為：He was doing homework at 9 o'clock last night．

點(diǎn)評(píng) 本題考查過(guò)去進(jìn)行時(shí)．根據(jù)圖片，找出能用的所有信息，聯(lián)想出句意，判斷時(shí)態(tài)，寫(xiě)出正確的句子．
