【題目】What are you looking for?

My homework. I_______it in my study. Why don't I find it now?

A.have leftB.leftC.leaveD.is leaving

【答案】B

【解析】

句意:——你在找什么呢?——我的家庭作業(yè)。我把它落在書房了。為什么就是找不到了呢?

考查動(dòng)詞的時(shí)態(tài)。have left已經(jīng)留下,現(xiàn)在完成時(shí)的結(jié)構(gòu);left留下,過(guò)去時(shí)的結(jié)構(gòu);leave留下,動(dòng)詞原形;is leaving留下,現(xiàn)在進(jìn)行時(shí)結(jié)構(gòu);根據(jù)句意理解可知,句中描述的是過(guò)去發(fā)生的事情,所以應(yīng)該用一般過(guò)去時(shí),所以這里的動(dòng)詞應(yīng)該用過(guò)去式,故選B。
