If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory(记忆力) is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.

解析

试题分析:
小题1:细节题。第一段When someone else says that his memory(记忆力) is poor, he really means that he does not give it enough chance to become strong.当另一个人说他的记忆力是差的时,实际上,他并没有给它足够多的机会来使它变得强大。可知,一个人的记忆力差,是因为记忆没有被经常使用。故选C
小题2:细节题。第一段If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again.如果你一段时间不使用你的胳膊或腿,他们会变得很乏力;当你再开始使用它们的时候,它们会慢慢变得强壮起来。故选C
小题3:判断题。你的记忆力的使用原理和你的胳膊、腿的使用原理是同样的。从Yet many people do not seem to know that memory works in the same way.可知,A正确。
像胳膊和腿一样,如果你不给记忆力足够多的机会去使用,你的记忆力会变得很差,B正确。如果你想要拥有一个更好的记忆力,就不要学习如何去读写,从最后两句可知,C错误。一个好的记忆力来自于更多的练习。从文章最后一句可知,D正确。故选C
小题4:细节题。从This is because they cannot read or write and they have to remember things they cannot write down in a little notebook.这是因为他们不能读或写,所以不得不记住他们不能记在笔记本上的事情。可知,他们不得不一直使用他们的记忆力。故选C
小题5:主旨题。本文主要讲的是,正如胳膊和腿,人的记忆力如果长时间不使用,就会变得很差。因此,如果一个人要想拥有好的记忆力,就必须更多的使用它。可知,本文的标题最好是:如何拥有好的记忆力。故选B
点评:本文着重介绍了如何增强记忆力,并通过和自己的手臂、腿进行类比进一步形象的说明如何来提高记忆力。文章意思明朗,所出的题目也不难,答题时学生牢记紧扣文章,将答案在文章中画出来再一一作答,定能够答得很好。
举一反三
Office workers should know that long periods of sitting at your desk may be a killer. Scientists have shown a new threat from this lifestyle that they call  “muscular inactivity (肌肉迟钝)”.
Sitting still for long periods of time leads to the buildup of substances (物质) in the blood that are harmful to health. And exercise alone won’t drive them away.
Millions of people spend their days between car,office desk and the sofa in front of the TV. While the bad influences are well rocognized,it has been thought that they can be changed by regular trips to the gym or swimming pool.
Now researchers say that is not enough. In addition to regular exercise,office workers need to keep moving while they work,by making regular trips to the printer,coffee machine or to chat with workmates.
Elin Ekblom­Bak,an expert on health,says research shows long periods of sitting and lack (缺乏)  of “whole body muscular movement”  are strongly linked to obesity,heart disease and cancer,and a higher risk of death,regardless of (不管) whether they take enough exercise.
“Everyone knows about the health benefits of regular exercise. But what we haven’t realized before is that long­period sitting down carries an extra risk that cannot be dealt with by taking exercise,” Dr Ekblom­Bak said,adding that sitting still should be recognized as a risk to health.
“It is important to have a five­minute break from desk work every 45 minutes. Don’t email workmates—walk across the office to give them the message. Take a coffee break or put the printer in the next room. I am a desk worker and I try to do it. It is not difficult but sometimes you get lost in your work and you forget about it.”
However,more studies are needed to confirm the ill effects of sitting for too long and ways of fighting them. But at present they conclude that  “keep moving”  should be added to the advice to “keep exercising.”
小题1:Nowadays,many office workers wrongly think that________.
A.long periods of sitting has bad influences on them
B.regular exercise benefits them after long periods of sitting
C.they are living a lifestyle called “muscular inactivity”
D.it’s unfair for them to sit in the office for too long
小题2:What does the author suggest office workers should do?
A.Chat with workmates often.
B.Send emails instead of chatting.
C.Keep moving in the office regularly.
D.Take more exercise after work.
小题3:The last paragraph suggests that the result of the study is________.
A.scientific B.uncertainC.unbelievableD.convincing
小题4:What would be the best title for the passage?
A.A new threat :long­period sitting
B.Office workers should keep exercising
C.Taking exercise benefits a lot
D.Keep moving,it could save your life

Every hour spent in watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research claims that a sedentary(久坐的) lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be associated with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England"s Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."
小题1:We can learn from the passage that_______
A.whether you watch TV or not has nothing to do with how long you will live
B.if an adult watches TV for six hours every day, he will die five years earlier
C.physical inactivity and obesity won"t shorten your life
D.a sedentary lifestyle offers huge benefits.
小题2:The word "it" in the second paragraph refers to
A.a sedentary lifestyle B.eating C.smoking D.obesity
小题3:What do we know from the last three paragraphs?
A.People in the United Kingdom watch TV longer than those in the United States.
B.That a sedentary lifestyle carries additional risks isn"t supported by other studies.
C.Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%.
D.It is through these studies that we know a sedentary lifestyle carries additional risks.
小题4:The passage is intended to _______.
A.inform the readers of a research on watching TV
B.warn the readers of the harm of watching TV and hope they do sports
C.tell the readers watching TV is also a good way to relax
D.tell the readers large amounts of people often watch TV

“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
小题1:We need _____for a healthy diet.
A.fibreB.foodC.waterD.Water and different foods
小题2:From the text, we know water can carry_________.
A.energy and fibre in our bodiesB.fruit, vegetables and fish in our bodies
C.sugar and fat out of our bodiesD.poisons and waste out of our bodies
小题3:Lack of water caused people to put on weight too much because_______.
A.they think they are hungry and eat too much
B.they think they are thirsty and eat less
C.water has no calories
D.it makes them hungry
小题4:Which of the following isn’t mentioned in the passage?
A.Fruit provides us with energy and fibre.
B.Some healthy problems start because of a lack of water.
C.Drinking more water may stop people from overeating.
D.The amount of water a person should drink in a day.
