1)He has been late for school three times ____the morning of last Friday.A.since

现在完成时应用的考查题目
has been 已经……
句意是：自从上周五早上到现在,他已经上学迟到三次了.
强调这一持续,强调那时到现在的影响.
现在完成时常有一些标志词,比如already,since,yet,等.
有问题请继续追问.
再问： 1)He has been late for school three times ____the morning of last Friday. A.since B.on 2)-Look at the noisy kids! -Haven't you heard the saying"when the cat is away,the mice________"? A.are playing B.will play 3)Peter is busy working at school,but he never forgets___________ exercise every day. A.to do B.doing 其实还有两道题但是这里字数限制
再答： 2、B When the cat is away, the mice will play. 俗语：山中无老虎，猴子称大王。俗语很多的，见一个记住一个就好。 要解释的话，就是说猫不在的时候，老鼠就会出来活动了。当……发生的时候，……就会……。后半句是在when引导的时间到来时才将要发生的事，所以用will。 3、A 句意：Peter在学校很刻苦，但是他从不忘记每日锻炼。 forget to do 忘记要去做某事。 (未做) forget doing 忘记做过某事。 (已做) 再给你个例句帮你理 ---- The light in the office is still on. ---- Oh，I forgot___. A. turning it off B. turn it off C. to turn it off D. having turned it off 答案：C。由the light is still on 可知灯亮着，即关灯的动作没有发生，因此用forget to do sth. 而forget doing sth表示灯已经关上了，而自己忘记了这一事实。此处不符合题意。 有问题继续追问哈，O(∩_∩)O~
再问： 4）-Where is Jack？ -He is away to spend his holiday.He's gone either to Hongkong or to Wuhan but I'm not sure ________. A.where B.which 5)-It's a miracle that the rescuers saved 123 workers who were trapped for more than a week in Wangjialing Coal Mine in Shanxi Province. -Sure it is.And they find it harder to save________________. A.another B.the others 辛苦了！
再答： 4 where 因为要想用which，应在前面加to，即He's gone either to Hongkong or to Wuhan but I'm not sure to which.而where可以直接作地点状语，不用加to就能用。 5 the others 剩下的。another 是另一个。句意来看就是能在山西王家岭矿难中救出被困超过一周的123名矿工实属奇迹，而再救这123人之外的就很难了，可能身体状况已经透支到就出来也没有生命迹象了。
