Walmart, which is one of the largest American supermarket chains, _______ some of its store open 24 hours on Mondays through Saturdays.
A.keepB.keepsC.have keptD.had kept
B

試題分析:句意:美國(guó)最大的連鎖超市之一沃爾瑪,從星期一到星期六會(huì)使它的一些商店保持24小時(shí)營(yíng)業(yè)。謂語(yǔ)動(dòng)詞是keep,句子表明的是一般的情況,故用一般現(xiàn)在時(shí),故選B.
點(diǎn)評(píng):時(shí)態(tài)是高考英語(yǔ)的重點(diǎn),單項(xiàng)選擇中15道有一半都是動(dòng)詞時(shí)態(tài)或是語(yǔ)態(tài)題?梢(jiàn)它的重要性,所以平時(shí)要分清楚16種時(shí)態(tài)的異同,并輔助以題目進(jìn)行加強(qiáng)鞏固,對(duì)復(fù)習(xí)階段不懂的一定要多問(wèn),并對(duì)所積累的知識(shí)進(jìn)行背誦。
