The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread fallacy(谬误) of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.    In the Second World War prisoners at the notorious Auschwitz Concentration Camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms.

Every year many students went to the college bookstore to purchase the different textbooks that they need for their classes. Little do these students realize that, in doing so, they are throwing good money away. It may sound unbelievable but textbooks, in some cases, actually cost as much as, if not more than, college fees.
Many people think that college bookstores are the most convenient source for textbooks. Titles are usually kept and students may purchase new textbooks or choose to buy second-hand books and save money. But the money saved by purchasing second-hand textbooks from college bookstores is small compared to the amount they could save by shopping online.
More and more online booksellers have begun selling textbooks at heavily discounted prices. Online second-hand bookstores are another source for college books as they keep a large number of textbooks, which means sizable savings for students. Students should avoid purchasing their textbooks at the first store that they surf online since there are so many ‘unreal’ booksellers on the Net. Price isn't the only factor to consider when making an online purchase. Students should also consider shopping costs and delivery time when making their decision.
Online auctions(拍卖) are another option for students seeking a bargain. This option, however, has its pros and cons. A plus is that students can get incredibly cheap books. One problem is that while online bookstores have a system in place that ensure you receive your order within a reasonable amount of time, with an auction purchase, however, you must depend on the auction seller's timetable.
One way that students can really save is by getting books for free. Project Gutenberg is one resource that English majors will find invaluable. Here students can legally download a huge collection of classic novels. In the past students needing help with their studies would often have to spend a lot of money buying expensive study guides. Today that is no longer the case. Cash-strapped students can now visit the website SparkNotes for free downloadable study guides as well as classics.
Which of the following is the best title of this passage?

A.Learning to Save on Textbooks B.Why Buy Textbooks
C.Online Shopping D.Tips for Buying Secondhand Textbooks

Which of the following is NOT mentioned as a source to obtain textbooks ?

A.College bookstores. B.Online used bookstores.

According to the passage, Project Gutenberg is probably __________.

A.a government project aimed at helping English majors
B.a project to help poor students get free learning materials

From the passage, we can learn that__________.

A.the cost of textbooks in college is low compared to the amount spent on tuition
B.online auctions are perfect for students seeking text books
C.students should visit many websites before buying their books
D.students should consider shopping costs and delivery time above all else when making their buying decision

Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer” Jason said, “He told us not to touch it.”
“He won’t find out,” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, so don’t touch it under any circumstances.” But his father’s warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead!” A new message appeared on the screen:
“ENTER NAMES
VOYAGE 1
VOYAGE 2
Mark’s finger flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED.
START TRANSPORT PROGRAM.
AUTO-RETRIEVE INITIATED(自动回收程序已启动).”
The screen turn even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒),until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed:
“TRANSPORT SUCCESSFUL.
DESTINATION: MARS.
RETRIEVE DATE: 2025

Everyone has got two personalities(个性)—one shown to the world and the other secret and real. You don't show your secret personality when you are awake because you can control your behavior, but when you are asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.
If you go to sleep on your back, you are a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to upset people, so you never express your real feeling. You are quiet, shy and you aren’t very confident.
If you sleep on your stomach, you are a rather secretive person. You worry a lot and you are always easily upset. You're very stubborn(顽固的), but you aren’t very ambitious(有野心的). You usually live for today, not tomorrow. This means that you enjoy having a good time.
If you sleep curled(卷曲) up, you are probably a very nervous person. You have a low opinion of yourself, so you are often defensive. You are shy and you don't normally like meeting people. You prefer to be on your own. You are easily hurt.
If you sleep on your side, you have usually got a well-balanced(通情达理的) personality. You know your strengths and weaknesses. You are usually careful. You have a confident personality. You sometimes feel anxious, but you don't often get depressed(沮丧的). You always say what you think even if it annoys people.
What would be the best title for the passage?

A.Two personalities.

The Body Temperature
The temperature of your body should be always just the same, no matter whether the weather is hot or cold. That is why the doctor uses his thermometer (温度计)when your are sick.
The body keeps the same temperature all the time ,because it balances the heat it produces and it gives off. It is always burning up food and , producing heat. It can produce heat faster when it needs to give off heat than when it becomes too warm. Let’s see how this happen.
The heat of your body is given off mainly through the skin. When you are cold, your skin is tight and shows “good flesh”. When you get chilly, you must dance around to keep warm or else you will shiver. Then your muscles begin to work, burn up fuel, and produce more heat. It is not pleasant to shiver, so you usually prefer to warm up by exercise, or put on more clothes to keep heat in.
When you are warm, the skin is loose and soft. It is so supplied with blood that heat is given off rapidly. If you get too warm, you begin to sweat ,and more body heat is used in evaporating the moisture(水蒸气) from your skin. You wear less clothing, too, in warm weather or warm room, so that warm can be given off freely. You feel less like exercising because your body is warm already, and the extra heat produced by exercise makes you uncomfortable.
You can see from the way you feel differently in different kinds of weather. In summer, when it is warm, you feel tired and lazy. You do not care to work or play, but enjoy lying and doing nothing. When you get out of doors in winter, the cold air makes you feel lively. You want to play.
Which is another title suitable of the passage?

A.The Patients’ Temperature
B.The Body Temperature Should Always Be the Same
C.The Body Temperature
D.The Temperature and Your Skin

How does the body keep the same temperature all the time?

A.It is always producing heat from food.
B.It gives off the heat produced in it.
C.It balances the heat it gets and loses.
D.It stops producing heat when necessary.

When one feels chilly, which of the following will he do?

A.His skin becomes tight in order to keep warm.
B.He does exercises to make his muscle produce more heat.
C.He puts on more clothes to keep heat in.
D.He keeps shivering to produce more heat.

When in summer, people prefer to_____.

A.work B.play C.do exercise D.relax and do nothing
