3、have downstream effects,holding up an entire line.If there are three lines in the store,delays will happen randomly at different registers.Think about the probability:3.So its not just in your mind:Another line probably is moving faster.Researchers have a good way to deal with this problem.Make all
4、customers stand in one long,snaking line called a serpentine line and serve each person at the front with the next available register.4.This is what they do at most banks and fast-food restaurants.With a serpentine line,a long delay at one register wont unfairly punish the people who lined up behind
5、 it.Instead,it will slow down everyone a little bit but speed up checkout overall.5.It takes many registers to keep one line moving quickly,and some stores cant afford the space or manpower.So wherever your next wait may be:Good luck.DFB专题二专题二 七选五七选五题组七题组七()A.Why does this always seem to happen to y

7、ter than the traditional approach.G.But sometimes,as on a Sunday afternoon,the system gets particularly busy.专题二专题二 七选五七选五题组七题组七()1._A解析 上文描述了你排队结账时,发现自己排的队伍比别的队伍慢这一现象,下文的It turns out chances are,the other line really is faster点明了结论,所以空处应为对该现象提出的疑问。结合选项来看,只有A项的内容与结论的内容相匹配。2._G解析 空前提到食品杂货店希望将结账延误降到最低
8、,空后提到任何小小的干扰都会拖慢整个队伍,两者形成转折,空处应明确转折关系,故G项符合语境。G项中的busy呼应下文的interruption holding up an entire line。专题二专题二 七选五七选五题组七题组七()【技巧点拨】空前的probability与D项中的chances和one in three呼应,同时D项与空后的So its not just in your mind:Another line probably is moving faster呼应。【易错点拨】考生可能会因E项中的probability而错选E项。但是E项(你排在最快的队伍里的可能性是多高?
9、)是个问句,不能对空前的probability进行解释说明;且根据空后的So可知,空处还要是空后句子的原因,E项同样不能作为原因,故排除E项。3._D解析 空前提到想象一下可能性,且与空处以冒号相连,表示空处是对可能性的解释说明,故D项符合语境。专题二专题二 七选五七选五题组七题组七()4._F解析 前一段提到如果商店里排起了三个结账的队伍,那么结账时延误情况的出现是随机的。本段提到研究人员为解决这一问题,想出了一个好办法:让所有人排成一队,排在最前面的人到可用的收银机处结账。F项能很好地承接上文,同时F项中的this method是空后This的指代对象。5._B解析 空后一句解释了很多商店
10、不采用只排一个队伍结账的办法的原因。故B项符合语境。解读:当你排队结账的时候,是不是总会感觉别的结账队伍比你的快呢?情况可能真的是这样。专题二专题二 七选五七选五题组七题组七()Passage 2(2020新高考卷,12.5分)Some individuals are born with a gift for public speaking.1.Do you want to be a good public speaker?Here are some principles you must master.People want to listen to someone who is inter
