A
The term “multitasking” originally referred to a computer’s 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 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 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 actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you’ve 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, your 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 habitual, or requires little thought. Most people don’t find it difficult to eat and read the newspaper at the same time. However, when two or more attention–requiring tasks are attempted at one time, people sometimes make mistakes.
We often don’t remember things as well when we’re trying to manage several 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 people’s names---even sometimes right after they have introduced themselves. Multitasking can also affect 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 multitasking?
A. To make them more productive.
B. To reduce their stress and anxiety.
C. To develop their communication skills.
D. To help them perform daily tasks more easily.
2. According to Paragraph 2, why may a person suddenly forget who has called?
A. He may leave his prefrontal cortex temporarily damaged.
B. He is probably interrupted by another task.
C. He is probably not very familiar with the person he has called.
D. He may need a rest between dialing and speaking.
3. People tend to make mistakes when ____.
A. they perform several challenging tasks at a time.
B. new messages are processed one after another
C. their relationships with others are affected
D. the tasks require little thought
4. What is the main idea of the passage?
A. Multitasking has become a way of life.
B. Multitasking often leads to efficiency decline.
C. Multitasking exercises need to be improved.
D. Multitasking enables people to remember things better.

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃．Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate．Without 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，humans have begun destroying rainforests in search of three major resources(资源)：land for crops，wood for paper and other products，land for raising farm animals．This action affects the environment as a whole．For example，a lot of carbon dioxide (二氧化碳)in the air comes from burning the rainforests．People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this．Firstly，when people cut down trees，generally they can only use the land for a year or two．Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply．
Rainforests are often called the world’s drug store．More than 25％ of the medicines we use today come from plants in rainforests．However，fewer than l％of rainforest plants have been examined for their medical value．It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests．
5．Rainforests can help to adjust the climate because they
．
A．reflect more heat into the atmosphere
B．bring about high rainfall throughout the world
C．rarely cause the temperature to drop lower than l6℃
D．reduce the effect of heat from the sun on the earth
6．What does the word “this” underlined in the third paragraph refer to?
A．We will lose much more than we can gain．
B．Humans have begun destroying rainforests．
C．People have a strong desire for resources．
D．Much carbon dioxide comes from burning rainforests．
7．It can be inferred from the text that
.
A．we can get enough resources without rainforests
B．there is great medicine potential in rainforests
C．we will grow fewer kinds of crops in the gained land
D．the level of annual rainfall affects wind patterns
8．What might be the best title for the text?
A．How to Save Rainforests
B．How to Protect Nature
C．Rainforests and the EnvironmentD．Rainforests and Medical Development

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 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, “Can I have one of those?”
He looked perturbed (不安). “Do you want to try it first?” he said, It didn’t 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 encouraging, “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, it 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, 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 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 well.
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. The shop assistant insisted that the writer should
A. try the camera to see if there was anything wrong with it.
B. compare the camera he had chosen with others.
C. get more information about different companies.
D. trust him and stop asking questions.
10. What does the writer mean by “it would be worth half what I paid for it ”(paragraph 2)
A. He should get a 50% discount.
B. the price of the camera was unreasonably high.
C. the quality of the camera was not good.
D. the camera would soon fall in value.
11. The writer decided to try the model he had chosen because
A. knew very little about it.
B. didn’t trust the shop assistant.
C. wanted to make sure the one he chose would be the best.
D. had a special interest in taking pictures of his fellow shoppers.
12. It can be inferred from the passage that in the writer’s opinion,
A. people waste too much money on cameras
B. cameras have become an important part of our daily life
C. we don’t actually need so many choices when buying a product
D. 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 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 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 familiar with characters from television shows and video games than common wildlife. without modem technology，a small Pond could be an amazing world filled with strange and beautiful plants，insects，birds，and animals 。when we lack meaning（交互）with the world around us, and
sometimes even with our families 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 missing a connection with the living world. 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.
13．The popularity of the lord of the rings proves
A．the close connection between man and the fantasy world
B．the wonderful achievements of fantasy literature
C．the fine taste of moviegoers around the world
D．the general existence of the sense of curiosity
14．What can we infer from the underlined sentence in Paragraph 3?
A．people are far less familiar with the world of fantasy
B．the world around us could serve as a source of wonder
C．the world of fantasy can be mirrored by a small and lively pond.
D．Modern technology prevents us from developing our sense of wonder
15．If our sense of wonder relies totally on the world of make-believe, we will
A．fail to appreciate the joy in our lives
B．be confused by the world of make-believe
C．miss the chance to recognize the fantasy world
D．be trapped by other worlds existing all around us
16. What is the main purpose of the passage?
A. To show us the hidden beauty in our world.
B. to warn us not to get lost in the fantasy world.
C. To argue against the misuse of the sense of wonder.
D. To discuss the influence of the world of make-believe.
