2021年1月高考英语浙江卷七选五真题（含答案+分析）
2021年1月浙江卷
You run into the grocery store to pick up one bottle of water. You get what you need, head to the front, and choose the line that looks fastest.
You chose wrong. People who you swear got in other lines long after you are already checked out and off to the parking lot. ___11___
It turns out, it’s just math working against you; chances are, the other line really is faster.
Grocery stores try to have enough employees at checkout to get all their customers through with minimum delay. ___12___Any small interruption – a price check, a chatty customer-can 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:____13____So it’s not just in your mind: Another line probably is moving faster.
Researchers have a good way to deal with this problem. Make all customers stand in one long, snaking line- called a serpentine line – and serve each person at the front with the next available register. ___14___This is what they do at most banks and fast-food restaurants. With a serpentine line, a long delay at one register won’t unfairly punish the people who lined up behind it. Instead, it will slow down everyone a little bit but speed up checkout overall.
____15____It takes many registers to keep one line moving quickly, and some stores can’t afford the space or manpower. So wherever your next wait may be: Good luck.
| A. | Why does this always seem to happen to you? |
| B. | So why don’t most places encourage serpentine lines? |
| C. | Some of the may have stood in a queue for almost an hour. |
| D. | The chances of your line being the fastest are only one in three. |
| E. | How high is the probability that you are in the fastest waiting line? |
| F. | With three registers, this method is much faster than the traditional approach. |
| G. | But sometimes, as on a Sunday afternoon, the system gets particularly busy. |
【答案】11. A 12. G 13. D 14. F 15. B
【解析】
【分析】本文是说明文。文章说明了杂货店排队方式以及研究人员提出的蛇形队伍的新方式，并分析了各自的利弊。
【11题详解】
下文“It turns out, it’s just math working against you; chances are, the other line really is faster. （原来，这只是你的数学问题；很可能，另一个队伍真的更快。）”解释了上文“You chose wrong.(你选错了)”的原因，下文与空格处是因果关系，所以本空应该是对前文选错提出疑惑，故选A项。
【12题详解】
上文“Grocery stores try to have enough employees at checkout to get all their customers through with minimum delay.（杂货店尽量让足够的员工在结账时让所有的顾客以最小的延误完成结账。）”解释了杂货店之前的工作模式，下文“Any small interruption a price check, a chatty customer -can have downstream effects, holding up an entire line.（任何一个小小的中断，一个价格检查，一个喋喋不休的顾客，都会产生下游效应，拖住整个生产线。）”描述了杂货店的特殊情况，故本空应该填出现特殊情况的原因，故选G项。
【13题详解】
根据上文“If there are three lines in the store, delays will happen randomly at different registers. （如果杂货店中有三列队伍，延迟将在不同的队伍中随机发生。）”联系下文“So it’s not just in your mind: Another line probably is moving faster.（所以这不仅仅是在你的脑海里：另一条队伍可能移动得更快。）”可知本空说的是任何一个队伍都有可能出现问题。你的队伍跑得最快的几率只有三分之一。故选D项。
【14题详解】
根据“上文Researchers have a good way to deal with this problem.(我们得知研究人员有一个很好的方法来处理这个问题)”以及下文“This is what they do at most banks and fast-food restaurants. With a serpentine line, a long delay at one register won’t unfairly punish the people who lined up behind it. Instead, it will slow down everyone little bit but speed up checkout overall.（这个大多数银行和快餐店都是这样做的。有了一条蜿蜒的队伍，在一个登记处长时间拖延不会不公平地惩罚后面排队的人。相反，它会减慢每个人一点点，但加快了整体结帐速度。）”说明这个新方案迅速有效，联系上下文可知，空格中应该是与旧的结账方案作比较。故选F项。
【15题详解】
结合下文“It takes many registers to keep one line moving quickly, and some stores can’t afford the space or manpower.（要保持一条生产线的快速运转，需要很多的收银机，而且有些商店负担不起空间和人力。）”说明了一个原因，由此可知，空格处提出了一个问题；通过“It takes many registers to keep one line moving quickly.(保持一条生产线的快速运转)”可知这里描述的是不鼓励蛇形队伍的原因。故选B项。
