Technological Utopia for Developing Countries
Cyberspace（网络空间）,data superhighways, multi-media, the linking of computers, television and telephones will change our lives forever. Yet for all the talk of a forthcoming technological utopia（乌托邦）,little attention has been given to the implications of these developments for the poor. As with all new high technology,the West concerns itself with the"how to benefit".The question of"for whom"is put aside once again.
Economists are only now realizing the full extent to which the communications revolution has affected the world economy.Information technology allows the extension of trade across geographical and industrial boundaries,and transnational corporations take full advantage of it. Terms of trade ex-change,interest rates and money movements are more important than the production of goods.The electronic economy made possible by information revolution.Technology allows the haves to increase their control on global markets and with destructive impact on the have-nots.
For them the result is instability. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine.As "futures"（期货）are traded on computer screens, developing countries simply have less and less control of their destinies.
So what are the options for regaining control?One alternative is for developing countries to buy in the latest computers and telecommunications themselves一so-called"development communications"modernization.Yet this leads to long-term dependency and perhaps permanent constraints on developing countries' economies.
Communications technology is generally exported from the U.S.,Europe or Japan.The patents, skills and ability to manufacture remain in the hands of a few industrialized countries.
Furthermore,when new technology is introduced,there is often too low a level of expertise to exploit native development.This means that while local elites,foreign communities and subsidiaries of transitional corporations may benefit,but not developing countries.
The development of modern communications technology in developing countries may______.
A:hinder their industrial production
B:cause them to lose control of their trade
C:force them to reduce their share of exports
D:cost them their economic independence

Learn About Noble Gases（惰性气体）
1 Have you ever ridden on a balloon?Many tourist spots offer balloon rides in order for people to see
the beauty of a place from above.A balloon contains a noble gas called helium（氦）.Formerly,balloons con-
tamned hydrogen but hydrogen is very flammable and dangerous when uncontrolled.Therefore,people shifted
to helium,which is safer. Helium is safe because it has the properties of the noble gases.
2 People once believed that noble gases couldn't chemically react at all.For this reason,they were
called inert gases(隋性气体）.They were also listed under Group 0 in the old periodic table because scien-
tists believed that the gases have zero valence（价）electrons in their outer shell.This was later proven to be
untrue when some noble gas compounds were discovered.
3 The gases are elements,which share similar properties.These properties include being monoatomic,
colorless,odorless,being able to conduct electricity,and having low chemical reactivity.Noble gases
include helium,neon,argon,krypton,xenon and radon.These are all found in Group 18,in the right most
column of the periodic table.If you look at the periodic table,you will notice that these elements are the only
ones which do not have a charge. Helium has the lowest molecular（分子的）weight while radon is the
heaviest.
4 Remember that chemical reactions occur because atoms have valence electrons,which are electrons
in their outer shell.When the outer shell is"unfilled"or the required number of electrons is not yet com-
plete,the atom is more reactive.Noble gases have a full outer shell,meaning that they have complete elec-
trons in their outer shell.This complete number varies.For instance,the outer shell of helium has 2 valence
electrons while the outer shell of xenon has 8 electrons.Nowadays,there remains to be a few noble gases
because of the low chemical reactivity of these said gases.
5 because of their properties,noble gases have many important applications.They are widely used in
medicine and industries. For instance , liquid helium is used for superconducting magnets（磁体）.These
magnets are very important in physics and medicine.When a doctor suspects that a person's brain has been
damaged,he might request for Magnetic Resonance Imaging(MRI).MRI allows the doctor to"see"the
brain,without operating on the patient.

A:What is the Periodic Table?
B:What are Noble Gases?
C:What Causes the Low Chemical Reactivity of Noble Gases?
D:How were Noble Gases Discovered?

Warm People Likely to Keep Cold at Bay
Staying positive through the cold season could be your best defense.against getting ill,new study findings suggest.In an experiment that exposed healthy volunteers to a cold or flu virus,researchers found that people with a generally sunny disposition were less likely to fall ill.
The findings,published in the journal Psychosomatic Medicine,build on evidence that a"positive emotional style"can help ward off the common cold and other illnesses.Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less trou- bled by a scratchy throat or runny nose.
"People with a positive emotional style may have different immune responses to the virus,"explained lead study author Dr.Sheldon Cohen of Carnegie Mellon University in Pittsburgh."And when they do get a cold,they may interpret their illness as being less severe."
Cohen and his colleagues had found in a previous study that happier people seemed less susceptible to catching a cold,but some questions remained as to whether the emotional trait itself had the effect.
For the new study,the researchers had 193 healthy adults complete standard measures of personality traits,self-perceived health and emotional"style".Those who tended to be happy,energetic and easy-going were judged as having a positive emotional style,while those who were often unhappy,tense and hostile had a negative style.
The researchers gave them nasal drops containing either a cold virus or a particular flu virus.Over the next six days,the volunteers reported on any aches,pains,sneezing or congestion they had,while the researchers collected objective data,like daily mucus production.Cohen and his colleagues found that based on objective measures of nasal woes,happy people were less likely to develop a cold.
The conclusion that happy people were less likely to develop a cold are based on subjective measures.

Transport and Trade
1. Transport is one of the aids to trade.By moving goods from places where they are plentiful to places where they are scarce,transport adds to their value.The more easily goods can be brought over the distance that separates producer and consumer,the better for trade.When there were no railways,no good roads,no canals,and only small sailing ships,trade was on a small scale.
2. The great advances made in transport during the last two hundred years were accompanied by a big increase in trade.Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand,for instance.Quicker transport makes possible mass-production and big business,drawing supplies from,and selling goods to,all parts of the globe.Big factories could not exist without transport to carry the large number of workers they need to and from their homes. Big city stores could not have developed unless customers could travel easily from the suburbs and goods were delivered to their homes.Big cities could not survive unless food could be brought from a distance.
3. Transport also prevents waste.Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns.Transport has given us a much greater variety of foods and goods since we no longer have to live on what is produced locally.Foods which at one time could be obtained only during a part of the year can now be obtained all through the year. Transport has raised the standard of living.
4. By moving fuel,raw materials,and even power,for example,through electric cables,transport has led to the establishment of industries and trade in areas where they would have been impossible before. Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The cheaper and quicker transport becomes,the longer the distance over which goods can profitably be earned. Countries with poor transport have a lower standard of living.
5. Commerce requires not only the moving of goods and people but also the carrying of messages and information .Means of communication,like telephones,cables and radio,send information about prices,supplies,and changing conditions in different parts of the world. In this way,advanced communication systems also help to develop trade.
Paragraph 2______
A: Higher Living Standard
B: impprtarice of Transport in Trade
C: Various Means of Transport
D: Birth of Transport-related Industries and Trade
E: Role of Information in Trade

Computers in Cars
You're far from home on a lonely road .Shadowy forests stretch away on both sides. A thick mist（雾）makes it difficult to see far beyond your car's windshield（挡风玻璃）.
“Can this be route 90A?”you wonder. if it is,you should be near a town. Yet there's no hint of one.Night is closing in. And you're low on gasoline.
This is a situation where an in-car computer that can navigate would be a big help.
A car computer that navigates?Yes!Such computers exist. Several experimental models are being tested by General Motors,Ford,Chrysler,and several foreign car makers.These computers vary in detail.But they all contain series of maps on videodiscs or videotapes.For example,one computer system contains 13,300 maps covering the continental US.
Before starting out on a trip,a driver can type in the code for the region he or she plans to drive through.The computer then shows a map of that region. At the same time,a tiny radio re-ceiver linked to the computer goes to work.It picks up signals from navigation satellites such as the NAVSTAR network.Using these signals,the computer shows the car's position at all times and displays this position on the map.The computer can also calculate and display the best route to follow.
A navigation computer may also receive and use data about road construction,weather condi-tions,and traffic jams. This information would be displayed to the driver and the computer would also use the information to work out alternate（交替的）routes.
Most cars nowadays also contain computers that help cars run more efficiently. Microproces- sors（微处理机）control certain engine functions by regulating the mixing of fuel. Data on car speed,oil pressure,revolutions per minute,engine temperature,and fuel level can be displayed as digital data(numbers)or warning lights.
Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level.Warning lights would indicate a drop in oil pressure or a sudden rise in engine temperature.To get more information on these conditions,the driver could call it up on the computer display screen.When needed,the computer could be “asked”to provide navigation aid or information about the car's condition.
Of the following functions,which is NOT possessed by the navigation computer?
A: Showing a map of the region a driver plans to drive through.
B: Predicting a car crash on the road.
C: Getting information about road constnzction,weather conditions,and traffic jams.
D: Showing the car's position at all times and displaying it on the map.

Verity Allen's New Show on Colors
1 Different colors can affect us in many different ways;that's according to Verity Allen.In her new se-
ries'Color me Healthy',Verity looks at the ways that colors can influence how hard we work and the
choices we make.They can even change our emotions and even influence how healthy we arc.
2 "Have you ever noticed how people always use the same colors for the same things?" says Verity."Our
toothpaste is always white or blue or maybe red.It'g never green.Why not?For some reason we think that
blue and white is clean,while we think of green products as being a bit disgusting. It's the same for businesses.
We respect a company which writes its name in blue or black,but we don't respect one that uses pink or orange.
People who design new products can use these ideas to influence what we buy."
3 During this four-pait series,Verity studies eight different colors,two colors in each program.She
meets people who work in all teipects of the color industry,from people who design food packets to people
who name the colors of lipsticks.
4 Some of the people she meets clearly have very little scientific knowledge to support their ideas,such
as the American"Color Doctor"who believes that serious diseases can be cured by,he use of colored lights.
However,she also interviews real scientists who are studying the effects of green and red lights on mice,with
some surprising results.
5 Overall,it's an interesting show,and anyone who watches it will probably find out something new.
But because Verity goes out of her way to be polite to everyone she meets on the series,it's up to the viewers
to make their own decisions about how much they should believe.

The Book of Life
So far, scientists have named about 1.8 million living species（物种）,and that's just a small part of
what probably exists on Earth.With so many plants,animals,and other creatures covering the planet,it can
be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon-to-be-launched Web site mighit help. An international team of researchers has announced the
creation of a Web-based Encyclopedia（百科全书）of Life(EoL).The project aims to catalog every species
on Earth in a single,easy-to-use referenice guide.
To get the encyclopedia started,the creators will use information from scientific databases（数据库）that
already exist. And eventually , in special sections of the site , nonscientists with specialized（专门的）
knowledge will get to join in Bird-watchers,for example,will be able to input which birds they'ye seen and
where.The technology for this kind of tool has only recently become available.
As the EoL develops,you might find it useful for school projects.The site will feature special pages for
kids who are studying ecosystems（生态系统）in their neighborhoods. To make sure the encyclopedia is
accurate,scientists will review much of the information added to it.People who visit the site will be able to
choose to leave out pages that haven't been reviewed.
Another convenient feature of the EoL is that you'11 be able to pick the level of detail you see to match
your interests,age,and current knowledge.If you wanted to learn about bears for a science class report,for
example,you could use the"novice"setting to get basic information about the animals.On the"expert"
setting,on the other hand,you could get much more detailed information about the history,literature,and
exploration of bears.
It now takes years for scientists to collect all the data they need to describe and analyze species.The
creators of the Encyclopedia of Life hope that their new tool will speed that process.
The word"novice"in Paragraph 5 could be best replaced by_________.
A:scientist
B:beginner
C:creator
D:expert
