1、2014-2015高三一轮复习第 九 期Editor: :刘向丽 Proofreader: 方新杰55分钟课堂练习集中识词第一部分 阅读理解 A The term “multitasking” originally referred to a computers ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic
2、 exercises (人脑训练) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that
3、 too much multitasking can lead to increased stress, anxiety and memory loss. In order to multitask, the brain uses an area known as the prefrontal cortex (前额叶脑皮层). Brian scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain ac
4、tually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if youve ever dialed (拨电话) a telephone number and suddenly forgotten who you dialed when the line is answered. What probably occurred is that between the dialing and the answering, you
5、r mind shifted to anther thought or task, and then look that “moment” to come back. Research has also shown that for many volunteers. Job efficiency (效率) declines while multitasking as compared to when they perform only one task at a time. Multitasking is easiest when at least one of the tasks in ha
6、bitual, or requires little thought. Most people dont find it difficult to eat and read the newspaper at the same time. However, when two or more attentionrequiring tasks are attempted at one time, people sometimes make mistakes. We often dont remember things as well when were trying to manage severa
7、l details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget peoples names-even sometimes right after they have introduced themselves. Multitasking can also affec
8、t our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them. 1. Why are some mental aerobic exercises designed to engage people in

13、 and adjust the climateWithout the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world In the past hundred years，human

There are two main reasons for thisFirstly，when people cut down trees，generally they can only use the land for a year or twoSecondly，cutting large sections of rainforests may provide a good

20、Save Rainforests BHow to Protect Nature CRainforests and the Environment DRainforests and Medical DevelopmentC I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the
21、 net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy, I pointed at it and asked an assistant
22、, “Can I have one of those?” He looked perturbed (不安). “Do you want to try it first?” he said, It didnt quite sound like a question. “Do I need to?” I replied ,“There is nothing wrong with it？” This made him look a bit insulted and I started to feel bad, “No, no, but you should try it,” he said enco
23、uraging, “compare it with the others.” I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, i
24、t seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop
25、, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model. But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end , I agreed to try the model I
26、had chosen. The assistant seemed a sincere man . So I let him take out of my chosen camera from cupboard, show how it took excellent pictures of my fellow shoppers and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as we
27、ll.Why do we think that new options (选择) still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.9.

31、 buying a productD. famous companies care more about profit than quality.D Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.This sense of wonder is universal. Look at the
32、 efforts that scientists（幻想）literature or movies like the lord of the rings. This sense of wonder draws us to each other，to the world around us ,and to the world of make-believe. but have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist
33、 all around us?Human beings，as biologists have suggested，possess an inborn desire to connect with and understand other life forms，However, people，especially in big cities，often lead rather isolated lives，In a study of British schoolchildren，it was found that children by age eight were much more fami

35、and friends，we seek to understand and communicate with things that exist only in our imaginations or on a computer screen。The world of make-believe is not necessarily bad, but when the world of fantasy becomes the only outlet（出路）for our sense of wonder，then we are really missing something，we are mis

Other wonderful worlds exist all around us. but even more interesting is that if we look closely enough，we can see that these worlds, in a broad sense, are really part of our own.13The popularity of the lord of the rings proves Athe close connection between m
