高考安徽卷)—i didn’t ask for the name list.why ________on my desk? —i put it there just now in case you needed it. a.does it land b.has it landed c.will it land d.had it landed 解析:选b。考查动词的时态。句意为:——我并没有要这份名单。为什么我的桌子上放着这东西?——这是我刚刚放的,以备你需要。i didn’t ask for和i put it there just now都表示过去的动作,很有迷惑性,但why has it landed on my desk?是到说话时为止的情况,名单在桌子上。现在完成时表示过去发生的对现在有影响的动作,故选b。 2.—__________ you see those people on that little sandy island?they __________ handkerchiefs for the last half hour.i wonder why. —they need help.the tide’s coming in and very soon that little island will be under water. a.do;have been waving b.did;have been waving c.do;had been waving d.did;had been waving 解析:选a。句意:——你看见小沙洲上的那些人了吗?半小时了,他们一直挥舞着手绢。我不知是怎么回事。——他们需要救援。潮水正在上涨,不一会儿那小岛就要被淹没。根据时态第一空采用一般现在时。现在完成进行时表示一个过去开始、现仍在继续的动作,所以第二空采用现在完成进行时。
