1. A.
   keep
2. B.
   keeps
3. C.
   have kept
4. D.
   had kept

Answer 1

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.
考點(diǎn)：時(shí)態(tài)
點(diǎn)評(píng)：時(shí)態(tài)是高考英語的重點(diǎn)，單項(xiàng)選擇中15道有一半都是動(dòng)詞時(shí)態(tài)或是語態(tài)題�？梢娝�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，并對(duì)所積累的知識(shí)進(jìn)行背誦。
