How far would you be willing to go to satisfy your need to know?Far enough to find out your possibility of dying from a terrible disease?These days that’s more than an academic question,as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的) tests,for everything from baldness to breast cancer,and the list is growing.Question is,do you really want to know what might eventually kill you?For instance,Nobel Prize­winning scientist James Watson,one of the first people to map their entire genetic makeup,is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年癡呆癥).
“If I tell you that you have an increased risk of getting a terrible disease,that could weigh on your mind and make you anxious,through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.” said Dr.Robert Green,a Harvard geneticist.
“Every ache and pain,” Smith suggested,could be understood as “the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease,then every time you can’t find your car in the parking lot,you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would,for lack of a better medical term,freak_out.But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives.In fact,most people think they can handle it.People who ask for the information usually can handle the information,good or bad,said Green.
小題1:The first paragraph is meant to________.
A.a(chǎn)sk some questions
B.introduce the topic
C.satisfy readers’ curiosity
D.describe an academic fact
小題2:Which of the following is TRUE of James Watson?
A.He is strongly in favor of the present genetic tests.
B.He is more likely to suffer from Alzheimer’s disease.
C.He believes genetic mapping can help cure any disease.
D.He doesn’t want to know his chance of getting a disease.
小題3:According to Paragraphs 3 and 4,if a person is at a higher genetic risk,it is________.
A.a(chǎn)dvisable not to let him know
B.impossible to hide his disease
C.better to inform him immediately
D.necessary to remove his anxiety
小題4:The underlined part “freak out” in Paragraph 5 is closest in meaning to “________”.
A.break downB.drop out
C.leave offD.turn away

小題1:B
小題2:D
小題3:A
小題4:A

小題1: B
解析 在第一段中通過兩個問題引出本文要談論的話題。
小題2: D
解析 根據(jù)第二段“Nobel Prize­winning scientist James Watson,one of the first people to map their entire genetic makeup,is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年癡呆癥).”可知,James Watson要求如果他的基因表明他有很高的老年癡呆癥的可能性不要告訴他。
小題3: A
解析 根據(jù)這兩個自然段可知,如果你提前被告知你將來可能患某種可怕的疾病,你可能會心情焦慮甚至精神崩潰。故A項符合。
小題4: A
解析 根據(jù)劃線詞所在句子及后一句可知,freak out的意思是break down(精神垮掉)。

Scott Langteau has this message for kids:spend less time playing video games.
It’s a message that many a mom and dad have tried to impress upon many a youngster (and some not­so­youngsters) who spend perhaps a bit too much time with game controllers in hand.
But the 40­year­old Langteau isn’t a parent.He’s a veteran (老手) of the video game industry—one who played producer on three “Medal of Honor” games and cofounded his own game development company.
Langteau has just published a children’s books called Sofa Boy,which tells the story of a kid who spends too much time sitting on the couch with controller clutched in hand and the rather terrible consequences that follow.
It’s a fairy tale plucked straight from Langteau’s own experiences as a lad with a fondness for video games and his own bouts with a bit of game addiction.But first,Langteau would like to make one thing clear,“I’m not saying that you shouldn’t play video games.I think video games are great.I think they do great things for kids.”Instead,Langteau says his book is all about a little something called moderation (克制).
“It’s about being well rounded,” he says.“Just like with anything else,we all need to make sure that there’s a variety in what we do.”
Video gamers can be rather bad­tempered when it comes to accepting criticism about their favorite entertainment.And understandably so.After all,most people who go around talking about the dangers of playing video games tend to be outsiders—people who don’t play video games and certainly don’t understand that they can be a valuable and healthy form of entertainment.
But Langteau and Sofa Boy seem to be in a  unique position to deliver a message of gaming moderation that the young game masses might actually listen to.After all,this is a man who understands what it means to be a kid with a passion for games.His early experience has taught him a lesson.
小題1:Scott Langteau published Sofa Boy to________.
A.share his great skills on games
B.warn kids against game addiction
C.tell about his fairy tale as a kid
D.deliver a message for video games
小題2:Which of the following is TRUE about Sofa Boy?
A.The book implies the writer’s own story.
B.The book describes a veteran of games.
C.The boy in the book wins a medal in games.
D.The boy in the book is not a video game addict.
小題3:We can learn from the passage that________.
A.Langteau advises the young to play games within limits
B.Langteau advises the young not to play games
C.playing video games ruins the future of kids
D.playing video games doesn’t benefit kids
小題4:By saying “It’s about being well rounded,...” (in Para.6),Langteau means________.
A.games do great good to kids
B.gamers are usually fat and round
C.games should be viewed from all sides
D.gamers are to blame for their behaviors

Life in space will certainly take some getting used to!But the space station has been designed to keep the astronauts as comfortable as possible—the modules(艙) are roomy,bright,and kept at a constant 70 degrees Fahrenheit.It’s important the crew members are comfortable because they’ll be busy aboard the station.In a typical workday,crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals,and 8.5 hours sleeping.Here are some other fun facts about life aboard the station:
Food
Come mealtime,astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions,astronauts could eat only freeze­dried food that didn’t require any preparation.But the space station is equipped with water,microwave ovens,and refrigerators,allowing the folks on board to eat more “normal” types of food,including fruit,vegetables,and ice cream!
Sleep
Each crew member has a private room.With no gravity,they’ll need to tie themselves to their beds,or they will float away!That might sound like a strange way to sleep,but astronauts from past space missions report that sleeping in space is actually pretty great!
Exercise
You might not think it,but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up,sit down or walk in space,so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this,astronauts on the station will exercise on bikes,rowing machines,and other equipment about two hours every day.
Clothing
Astronauts will have to wear special space suits while traveling aboard the U.S.shuttle or Russian rockets.But once they’re safe inside the space station,crew members can wear regular clothing.Of course,a specially designed,pressurized space suit is required for space walks.It has to withstand(經(jīng)受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.
Personal Cleanliness
Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble!Astronauts will use a freshwater hose(軟管) to take showers,shampoo,and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space?With a special “air toilet” that uses flowing air instead of water to dispose of waste.
小題1:The facts about life in space are all mentioned EXCEPT ________.
A.clothingB.entertainment
C.sleepD.exercise
小題2:What can be learned from the paragraph “Clothing”?
A.The temperature is quite different in different places in space.
B.Astronauts must wear special space suits all the time in space.
C.Astronauts can wear regular clothing for space walks now.
D.Astronauts wear pressurized space suits just to keep warm.
小題3:Why is exercise more important in space than on earth?
A.It can make astronauts feel relaxed in space.
B.It can help astronauts spend their spare time happily.
C.Astronauts’ lives are more important in space than on earth.
D.It can prevent astronauts from causing muscle and bone loss.
小題4:What do we know about space food from the text?
A.Astronauts could eat apples in space in the past.
B.Astronauts eat only fruit,vegetables and ice cream now.
C.Fresh food isn’t available to astronauts in space.
D.Space food is getting better now than before.

  How would you like to teach yourself, rather than have teachers? According to the UK’s Department of Education and Skills, students will teach themselves in the schools of the future. This means that there will be no more problems such as finding enough teachers.
Estelle Morris, the UK Education Secretary, opened the 2002 Education Technology Conference in London recently. To start the conference, she presented a video showing a computer—generated model of the school of tomorrow.
Greater use of computer technology and classroom assistants will help students develop their own way of learning, Morris said. She added that this is a more exciting as well as a more interesting way of learning.
At the same time, teachers will be “freed from their traditional role as the source of all knowledge”.
Children of all abilities will “form the curriculum(課程)around their individual needs.” They will “l(fā)earn in their own time, at their own speed and in their own environment”.
At home or at school, they will follow their learning programmes by looking at online libraries and watching lessons by world-class teachers and subject experts.
Instead of going on field trips, students will use virtual reality. If they don’t understand something, they can ask other students—“take part in virtual communities with learners with similar needs”—or e-mail their teachers. They will hand in their work electronically to be “auto-marked”.
The classroom of the future is fast becoming a reality.
And the Department of Education will soon produce a guide to help schools adapt buildings for new technology, Morris said. These ideas are based on the UK government’s plan to create an education system that provides students with a strong grounding of knowledge and skills at primary school level. And provides the chance for students to develop their individual skills at secondary school level.
小題1:According to the UK’s Department of Education and Skills, the school of the future will ______.
A.cause more problems such as being able to find enough teachers
B.set no homework and no tests for students
C.make good use of the computer technology and classroom assistants
D.enable students to learn by themselves without teachers
小題2:Estelle Morris thinks that computer technology does good to teachers in ________.
A.helping students develop their own way of learning
B.enabling students to experience interesting and exciting ways of learning
C.providing students with knowledge of all sorts
D.not being considered the source of various knowledge
小題3: If the students do not understand something, they can _______.
A.go on a field trip
B.go to ask their teachers to help them
C.send e-mail to ask for a teacher’s help
D.have a look at other learners’ homework
小題4: If s a student is under the UK’s newly-developed education system,he will be ________.
A.provided with a basic knowledge from the beginning
B.given more knowledge at primary school level
C.helped to use computers better
D.supplied chance to develop their basic skills

Boredom and Creativity
Most of us think of being bored at work as a negative experience, but a new study suggests it can have positive results including an increase in creativity because it gives us time to daydream.
That is the finding of Dr. Sandi Mann from the University of Central Lancashire. Dr. Mann conducted two studies. In the first experiment, 40 people were asked to carry out a boring task. They were told to copy numbers out of a telephone directory for 15 minutes. After that they were asked to complete another task. A pair of cups were given to each of them. Everyone tried to come up with different uses of the cups, and was given a chance to display their creativity. Meanwhile, another group of 40 people were just asked to come up with uses for the cups without doing any boring tasks before. It turned out that the 40 people who had first copied out the telephone numbers were more creative than the control group(對照組).
To see if daydreaming was a factor in this effect, a second boring task was introduced that allowed even more daydreaming than the boring writing task. This second study saw 30 people copying out the numbers as before, but also included a second group of 30 reading rather than writing them.
Again the researchers found that the people in the control group were least creative, but the people who had just read the names were more creative than those who had to write them out. This suggests that more passive boring activities, like reading or perhaps attending meetings, can lead to more creativity. Compared with reading, writing reduced the scope(范圍) for daydreaming. As a result, it reduces the  effects of boredom on creativity.
Dr. Mann says: “Boredom at work has always been seen as something to be avoided, but perhaps we should accept it in order to promote our creativity. What we want to do next is to see what the practical implications of this finding are. Do people who are bored at work become more creative in other areas of their work -- or do they go home and write novels?”  
小題1:Who proved to be the most creative in the two studies?
A.The people who attended meetings.
B.The people who did the reading task.
C.The people who invented uses for cups.
D.The people who copied telephone numbers.
小題2:The studies conducted by Dr. Mann indicate that creativity results from _______.
A.creative tasks
B.controlled activities
C.the range of daydreaming
D.reading and writing ability
小題3:What is Dr. Mann’s attitude towards boredom at work?
A.Positive.
B.Skeptical.
C.Subjective.
D.Disapproving.
小題4:What will Dr. Mann probably continue to research in their study?
A.The real causes of creativity.
B.The actual use of boredom.
C.The practical reasons of boredom.
D.The writing ability improved by boredom.

A wave of recent research has pointed to the risks of over praising a child. And it seems that how to draw a line between too little praise and too much has become a high-pressure _  _act for parents.
Self-esteem (自尊)  serves as a kind of tool to measure how much children feel valued and accepted by     . This sensitivity to others'      develops because of humans' need for social acceptance, which is considered to be      to survival. As early as age 8, children's self-esteem tends to rise and fall in response to feedbacks about      peers see them as likable or attractive.     , it can also be beneficial for kids to feel bad about themselves occasionally, if they behave in selfish, mean or hurtful ways that might      their ability to maintain relationships or hold a job in the future.
In the past, many parents and educators believed that high self-esteem      happiness and success, and kids could gain self-esteem simply by getting      and awards from their parents, teachers and people around. But recently researchers have found self-esteem doesn't  _   these desired results. Instead, if parents praise their kids     , their self-esteem becomes focused on being very smart and being the best and being perfect. Building too much self-esteem of the children can not go as planned, making them feel      later on when they hit setbacks (挫折).
According to some experts, it can actually be good for kids to have      self-esteem, at least once in a while. And praise can be      if it disregards the world outside the home. Children who have a      understanding of how they are seen by others tend to get recovered more readily      disappointment, depression or the like. The best path is a      road, helping children develop a positive but      view of themselves in relation to others by praising them for the      they invest and behaviors they are able to sustain, like "It's      that you're working so hard on your homework. "

A kitchen that gives step-by-step cooking instructions in French could inspire a revolution in language learning in the UK. By using a new technology, it speaks to you as you prepare a French dish. The kitchen breaks new ground by taking language learning out of the classroom and linking it with an enjoyable and rewarding real-life activity.
The new kitchen is designed to be used in schools, universities and even people’s homes. It could also be an existing kitchen. The first version of the technology was tested in the kitchens of project partner Newcastle University. The kitchen could be available for schools and universities, and for the UK market by the June of 2014.
The Newcastle University team is now working on ways to put it on the market. And the European Union has given money to begin programs in six other languages, including English Italian and Spanish. Finally, versions could be developed for any language cuisine(烹飪法)in the world.
Professor Paul says, “By international standards, the UK students are now poor when it comes to learning languages—a problem that certainly has an economic influence. We believe that developing skills in a country’s language and its cuisine will help change the trend.”
On a computer fixed into the kitchen, the user first selects the French recipe(菜譜)they want to follow. Digital sensors built into dishes, containers and other equipment then communicate with the computer to make sure the right instructions are given at the right time, the user can ask the computer to repeat an instruction, or translate it into English, simply by pressing the touch screen. After cooking, the user can test what they have learned by carrying out a short test on the computer.
All grammar and vocabulary has been carefully selected to make sure that using the kitchen adds to basic proficiency(熟練)in understanding French.
Now three easy-carrying versions of the kitchen are being prepared. They’re to be fixed in Newcastle University and at Institute Francais, a London-based charity devoted to teaching the French language.
小題1:The new kitchen is designed mainly to __________.
A.increase people’s interest in cooking
B.teach people how to cook French dishes
C.offer people a new way to learn languages
D.help cooks learn spoken French in the kitchen
小題2:Which of the following is TRUE about the kitchen?
A.It has versions in six languages now.
B.It is already available for sale in the UK.
C.It has received strong support from the EU.
D.It can be used only in schools and university.
小題3:When a person is using the kitchen, ___________.
A.it will give him a test on his cooking skills
B.it can translate French into another language
C.the cooking process will stop if he goes wrong
D.he must be careful so as not to make mistakes
小題4:What would be the best title for the text?
A.UK students have problems in language learning.
B.New technology helps students learning cooking.
C.An enjoyable and rewarding real-life activity.
D.A Talking Kitchen That Teaches You French.
