“High tech” and “state of the art” are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention， system or device （设备） that uses the newest ideas or discoveries of science and engineering.

What is high tech？ A computer is high tech. So is a communication satellite. A modern manufacturing （制造业的） system is surely high tech.

High tech became a popular expression in the United States during the early 1980s. Because of improvements in technology， people could buy many new kinds of products in American stores， such as home computers， microwave ovens， etc.

“State of the art” is something that is as modern as possible. It is a product that is based on the very latest methods and technology. Something that is “state of the art” is the newest possible design or product of a business or industry. A state of the art television set， for example， uses the most modern electronic design and parts. It is the best that one can buy.

“State of the art” is not a new expression. Engineers have used it for years to describe the best and most modern way of doing something.

Millions of Americans began to use the expression in the late 1970s. The reason was the computer revolution （计算机革命）. Every computer company claimed that its computers were “state of the art”.

Computer technology changes so fast that a state of the art computer today might be old tomorrow. The expression “state of the art” has become as common and popular as computers themselves. Now all kinds of products are said to be “state of the art”.

1. What do “high tech” and “state of the art” describe？

A. Modern art. B. Home computers.

C. Very modern technology. D. Education in the future.

2. Millions of Americans began to use “state of the art” because of ___ .

A. engineers B. the latest technology

C. the computer revolution D. new kinds of products

3. What can we infer from the passage？

A. A wooden spoon is “state of the art”.

B. “State of the art” became popular earlier than “high tech”.

C. “High tech” decribes a technology that is traditional.

D. American stores could provide all kinds of products for people.

4. Whats the best title of the passage？

A. Computer Technology

B. Two New Expressions

C. Most Advanced Technology

D. High Tech and State of the Art

There is that great an idea that in an information and knowledge based economy， the most important thing for companies is attracting and holding outstanding talented guys. Obviously I will not say that is not important， but in my opinion a successful and groundbreaking company cannot be built just from the collection of high talented people， as a great sports team cant be constructed only by the collection of great players.

It is more important to build teams of people that achieve the goals according to the companys organizational vision （洞察力）. It is necessary to create organizations where everybody （with outstanding talent or not） can develop their best personal abilities and that these abilities are addressed to achieve the corporate （共同的） goals and mission. The companys efforts must be addressed to design an organizational system that produces and uses talent from everyone in the company.

Trying to get the best from our people through corporate team building policies， establishing a concrete corporate culture and values， making our company a place where people want to work because it is a good place to stay and develop their abilities， is the best way to compete in the knowledge economy. That will keep us out of the obligation to continually seek for the “best players” and entering in the retribution auctions （拍卖）.

We have to take into account that， nowadays， the real talented and creative people like to work or keep themselves busy in projects where they can develop their abilities， where they can be involved in the organizational goals and vision， and where they are treated with respect and dignity. Definitively， they want to be happy doing their jobs. And we have to build organizations where they can find that.

5. The underlined word “that” in Paragraph 1 refers to ___ .

A. the great idea

B. information and knowledge

C. the collection of talented people

D. attracting and holding talented people

6. According to the author， a good company should consist of ___ .

A. only common people

B. only outstanding people

C. both talented and common people

D. more talented people than common people

7. The most important thing a successful company should do is ___ .

A. continually seeking for talented people

B. employing people with different abilities

C. making the company a place where employees can get the best pay and great respect

D. making the company a place where employees are glad to devote themselves to work

Everyone has probably seen a movie or two about robots going against humans. As a kid it was interesting， but not a reality. But today， when we look at how far scientists have come， its not just a funny thought but a real possibility.

Honda has already created a robot with eyes， legs， arms and hands and it can act just like a person. There is no end to what a robot could do in the future. Just think what we can do in twenty to thirty years. Were dealing with almost an entire new species of human-like robots that could be cleverer than us. Can we continue to use these robots in a way that they serve us， or will they become so wise that they will want independence？

I am really not sure just how far scientists are going to perfect robots. But once this type of robot is made， they will be able to think， make decisions， sense the movement of others and decide what it wants to do.

A new invention has led to the introduction of a female robot， which was introduced at an entertainment show in Vegas. The robot called Roxy sells for between seven and ten thousand dollars. It is built to accompany females. This female robot companion is called true companion and you can find such robots on the Internet. Robots used to have limited uses， but now they are almost in every field. This has opened the door to many dangerous possibilities in the future.

1. What did we think about a robot when we were kids？ （within 6 words）

2. What could robots do in the future？ （within 10 words）

3. Which kind of robots may think as humans beings do？ （within 3 words）

4. Whats the purpose of inventing a female robot？ （within 3 words）

5. Why does the writer worry about robots in the future？ （within 9 words）

During the Christmas shopping rush in London， the interesting story was reported of a tramp （流浪汉） who， obviously though no fault of his own， found himself locked in a well-known chain store late on Christmas Eve. No doubt the store was crowded with last-minute Christmas shoppers and the staff were dead beat and wanting to get home. Probably all the proper safety checks were made before the store was locked and they left to enjoy the three-day holiday untroubled by customers anxious to get last-minute Christmas presents.

However ridiculous that may be， the tramp found himself alone in the store and decided to make the best of it. There was food， drink， bedding and camping equipment， of which he made good use. There must also have been television sets and radios. Though it was not reported if he took advantages of these facilities， when the shop reopened he was discovered in bed with a large number of empty bottles beside him. He seemed to have been a man of good humor as indeed tramps very commonly are.

Everyone else was enjoying Christmas， so he saw no good reason why he should not do the same. He yielded himself cheerfully， and was taken by the police. Perhaps he had had a better Christmas than usual. He was sent to prison for seven days. The judge awarded （判给） no compensation （赔偿） to the chain store for the goods the tramp had used. They had， in his opinion， already received valuable free advertisement from the story revealed in the newspaper and on television. Perhaps the judge had had a good Christmas， too.

1. The tramp was locked in the store ___ .

A. for 7 days B. on purpose

C. by accident D. for safety reasons

A. Angry. B. Exhausted.

To the American visitors Iceland is a very interesting country， partly because it is different in so many ways from what he or she is used to seeing at home. There are quite a few things that are not done， or that do not exist on the island—quite a few “noes”.

There is no pollution， for example. No dogs are permitted in Reykjavik， the capital. There is no television on Thursdays or during the whole month of July， and only three hours of black-and-white TV the rest of the time. There is no hard liquor （酒） on Wednesdays and no beer at any time. There are no handguns； only one jail of 35 cells （小牢房） in the whole land—an admirable figure， even for a small country of 222，000 people.

There is no army， air force or navy. There is no tipping for anything. There are no large stores open on Saturdays and Sundays. Since Iceland is located just under the Arctic Circle， there is no darkness in summer and no daylight in winter. But thanks to the Gulf Stream， the climate is rather warm， with temperatures ranging from 34 degrees Fahrenheit （华氏温度） to 52 degrees in July.

The rules on television， liquor， and guns are the result of governmental decision. But the absence of pollution is due in great part to the fact that Iceland gets its power from the enormous geysers （间歇喷泉） and the thousands of hot springs that come out of ground. They provide all the energy needed by the country. In fact， Iceland uses only 3 percent of all its available power.

Iceland has been described as an independent country where more fish are caught and more books are published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They composed their first works in the ninth and tenth centuries AD. These works were poems and stories about the kings， heroes， and heroines of Iceland and Norway. At first the stories were memorized and passed from generation to generation. They were finally written down between 1140 and 1220. The Icelanders have never stopped writing ever since. “Rather shoeless than bookless，” they proudly say.

5. The American visitor enjoys visiting Iceland because ___ .

A. the climate is rather mild

B. it is very different from America

C. the police do not carry handguns

D. no dogs are permitted in the capital

6. It can be inferred from the passage that in Iceland ___ .

A. the sun doesnt set in winter

B. the sun rises and sets regularly

C. the sun never rises in winter and never sets in summer

D. the climate is rather mild because there is no daylight in winter

7. There is no pollution in Iceland mainly because ___ .

A. it is an independent country

B. it is located just under the Arctic Circle

C. Iceland uses only 3 percent of all its available power

D. the Icelanders use hot water from under ground as their energy

Feel tired lately？ Has a doctor said he cant find anything wrong with you？ Perhaps he has sent you to a hospital， but all the advanced equipment there shows that there is nothing wrong with you.

Then， consider this： you might be in a state of sub-health （亚健康）.

Sub-health， also called the third state or gray state， is explained as a borderline state between health and disease.

According to the survey by the National Health Organization， over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week.

Symptoms include a lack of energy， depression， slow reactions， insomnia， anger， and poor memory. Other symptoms include shortness of breath， sweating and aching in the waist and legs.

The key to preventing and recovering from sub-health， according to some medical experts， is to form good living habits， alternate work and rest， exercise regularly， and take part in open air activities.

As for meals， people are advised to eat less salt and sugar. They should also eat more fresh vegetables， fruits， fish because they are rich in nutritional （营养的） elements—vitamins and other elements that are important to the body.

Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract （消化道）. They also say that a balanced diet is very helpful in avoiding sub-health.

1. It may be easy for middle-aged people to get sub-healthy because ___ .

A. they begin to get older

B. they have used up their energy

C. they have lost their living hopes

D. they have more pressure in life and work

2. The key to preventing you from falling into a state of sub-health is that you should ___ .

A. work hard B. sleep more

C. take more medicine D. form good living habits

3. The underlined word “alternate” probably means ___ .

A. get tired of B. arrange by turns

C. cause to take place D. keep oneself busy with

In the past， people who graduated from college felt proud of their academic achievements and confident that their degree （学位） would help them to find a good job.

However， in the past four years the job market has changed greatly. This years college graduates are facing one of the worst job markets. For example， Ryan Stewart， a graduate of San Jose State University， got a degree in religious studies， but he has not got any job offers. He points out that many people already working are getting laid off （失业） and dont have jobs， so its even harder for new college graduates to find jobs.

Four years ago， the future looked bright for his class of 2009. There were many high-tech （“dotcom”） job opportunities， graduates received many job offers， and they were able to get jobs with high salaries and benefits such as health insurance and paid vacations. However， “Times have changed. Its a new market”， according to an officer of the university.

The officer says students who do find jobs started preparing two years ago. They worked during summer vacations， they have had several short-time jobs， and they majored in fields that are still paying well， such as accounting or nursing.

Even teaching is not a safe profession now. Ryan Stewart wanted to be a teacher， but instead he will probably go back to school in order to become a college teacher. He thinks college teaching could be a good job even in a bad economy.

In conclusion， these days a college degree does not lead to a good job with a high salary. Some students can only hope that the value of their degree will increase in the future.

5. What did a college degree mean to people in the past？

A. It was a proof of their professional skills.

A. Teaching jobs are well-paid.

B. He majored in teaching in the university.

C. College teaching is less challenging than high-tech jobs.

D. College teaching career wont be influenced by economy.

8. It can be concluded from the passage that ___ .

A. graduates must prepare early to find jobs

Just like humans， birds also rely on sound to communicate. However， they do not have a “language” in the true sense of the word and instead produce a variety of sounds to express different emotions.

Often， birds recognize their mates （or young） by sound rather than sight. Hungry young birds use begging calls to let their mothers know it is feeding time. Alarm calls， flight calls and warning calls are other sounds made frequently by adults.

A new study shows that songbirds rehearse （排演） their songs even in their sleep. The activity in the brain of the birds when asleep is similar to the brain activity when the birds were awake and singing. The team used tiny recording devices to measure the activity of individual brain cells in four songbirds both when they were singing and when they were asleep.

Obiviously this kind of bird stores a song after hearing it， and then rehearses it later in its sleep. Scientists now believe the birds “dream of songs and tunes” to help them master the fine art of singing and that sleep plays a key role in the learning process！

Many songbirds learn to sing by listening to adult birds of the same species. However， if separated from the adults， the young birds develop sounds which are hard to understand instead of normal song patterns. Researchers carried out an experiment in which a male bullfinch （红腹灰雀） was raised by a female canary （金丝雀）. The bullfinch soon learned the canarys song and when it was later mated to a female bullfinch， Mr Bullfinch taught his children the canarys songs.

Last year， a British survey of Londons songbirds showed that the citys birds are losing their tunes. Birds could hardly hear one another， over the traffic noise； as a result， instead of copying the sweet notes of the adults， young birds were copying the sounds they heard most often， namely car horns and beeping cellphones！

In a mountainous area of Brazil， there is a kind of beautiful butterfly which can kill men. If people meet them， they will come down in great quantities to bite and kill， sucking （吸） blood and eating flesh through the wounds they cause.

In June， 1966， a boy named Marl Andre who went into the mountains in search of butterfly specimens （标本） was killed by these butterflies. A country boy saw him as he was just about to raise his net to catch a butterfly. Suddenly thousands of butterflies came down upon him， covering him all over. The boy struggled and cried as he tried to free himself from their attack. Finally he fell senseless to the ground. Police examined his body and proved that he had died of bites by butterflies.

In New Guinea， there is a kind of needlefish which also kills men. Because it likes light at night， it will swim near the lights of fishing boats， then suddenly shoot out of water like an arrow to its target， and force its 3-inch sharp mouth into a human body. Often people are thrust （戳） in the eye， or through the chest or stomach， resulting in death. Sometimes it will even attack the people in a fishing boat in broad daylight.

About 10 persons in the world are killed by sharks every year， yet more than 20 are killed by needlefish every month.

Against the supposition that forest fires in Alaska， Canada and Siberia warm the climate， scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

This finding suggests that taking steps to prevent northern forest to limit the release （释放） of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past ten years. Scientists predict that with climate warming， fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming， while heat mirrored back into space tends to cause cooling.

This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus catch heat.

Scientists found that right after the fire， large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone （臭氧） levels increased， and ash from the fire fell on far-off sea ice， darkening the surface and causing more radiation （辐射） from the sun to be taken in. The following spring， however， the land within the area of the fire was brighter than before the fire， because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space， leading to cooling.

“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire， and found a measurement closely related to the global air temperature. Typically， fire in northern regions occurs in the same area every 80 to 150 years. Scientists， however， found that when fire occurs more frequently， more radiation is lost from the earth and leads to cooling results. Specifically， they determined when fire returns 20 years earlier than predicated， 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases， but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is got or lost from the earth.

5. According to the new findings， taking steps to prevent northern forest fires may ___ .

A. result in a warming climate

B. lead to a longer fire season

C. protect the forests and the environment there

D. cause the forest fires to occur more frequently

6. Earlier studies about northern forest fires ___ .

A. indicate that forest fires will pollute the atmosphere

B. suggest that the fires will speed up climate warming

C. analyze all aspects of how northern fires influence climate

D. suggest that people should take measures to protect environment

7. The underlined phrase “soaked up” probably means ___ .

A. released B. absorbed

C. created D. distributed

8. From the passage we can draw a conclusion that forest fires in Alaska， Canada and Siberia may ___ .

A. warm the climate as the supposition goes

B. help to get more energy rather than release more energy

C. destroy large areas of forests and pollute the far-off sea ice

D. allow more snow to mirror more sunlight into space and thus cool the climate

Cloning Pets克隆宠物

Is animal cloning for real？ I want to have my dog cloned.

Well， animal cloning technology exists， but pet cloning isnt quite there yet. And it may never be.

Why not？ I could think lots of people could want to have copies of their pets.

Thats just a problem： a clone isnt a copy. Its a separate， individual organism. The only thing clone of Mr. Dogs and Mr. Dogs of themselves have in common is their genetic sequence.

The only thing？ Isnt that everything？

Apparently not！ As cloning technology has improved， more and more evidence has come out of clones that dont look alike or act alike. For example， Ted Friend and Greg Archer， both at Texas A& M， have cloned piglets.

They report that there is just as much variation in appearance among the clones as among the non-clones. Some have bristly coats， others not； some have more teeth， some fewer.

But wouldnt a clone at least have its charming personality？

Maybe. The worlds first cloned cat was made by Duane Kraemer， also at Texas A & M. He reports that the clone has a different personality altogether than its clone mother–its much more friendly， in fact.

动物真的可以克隆吗？我想克隆我的狗。

动物克隆确实存在，但是，宠物克隆现在还没有。估计以后也不会有。

为什么不呢？我觉得有不少人想克隆宠物吧？

因为你得考虑这样一个问题：克隆并非复制。克隆是一个独立的生物个体。狗狗先生的克隆产物和它本身唯一的共同点在于基因序列。

只是基因序列吗？不是所有的都相同？

当然不是！随着克隆科技的不断发展，越来越多的证据显示克隆并非看起来一样或行为一样。比如，得州农工大学的Ted Friend 和Greg Archer教授克隆了一批小猪。

报告显示在克隆猪和正常繁殖的猪并无二致，都存在生物变异。有的鬃毛较多，有的没有鬃毛。有的牙齿更多；有的牙齿更少。

克隆的宠物至少保留了讨人喜欢的个性吧？

可能会哦！同是得州农工大学的Duane Kraemer研究出了世界上第一只克隆猫。克隆猫的性情和原来那只猫的性情大不同——友善了不少。
