Internet. However, you can also find many weather signs among wildlife, because of their highly developed
senses. Drops in air pressure (压力) produce an effect on small animals in many ways. Mice and deer are
good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field
mice come out of their holes and run around. Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many
ways. For example, some birds become irritable (急躁的) and quarrelsome and will fight over a piece of bread.
Other birds chirp (叽叽喳喳) and sing just before a storm. It seems they know they won"t get another chance
for an hour or two. Birds also seek safe places before a storm. You will sometimes see birds settling in trees
or gathering together on a wire close to a building. Pre-storm low pressure makes the air so thin that birds
have difficulty flying.
It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the
spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may
be flying ahead of a storm.
By paying closer attention to some important signs in nature, we can become better prepared for any kind
of weather.
B. services
C. signs
D. stations
B. fly in different directions
C. come down from tall trees
D. share a piece of bread
B. By noticing the change of wind directions.
C. By feeling a drop in air pressure.
D. By noticing the movements of other animals.
B. Drops in Air Pressure
C. Animals" Sharp Senses
D. Nature"s Weather Signs

hardly know a time when computers weren"t around, and they eagerly catch the chance to spend hours online,
chatting with friends, So what?
But researchers nationwide are increasingly worried that teens are becoming isolated (孤寂), less skillful at
person-to-person relationships, and perhaps numb (麻木) to the cheatings that are so much a part of the e-mail
world. "And a teen"s sense of self and values may be changed in a world where personal connections can be
limitless,"said Sherry Turkle.
Another researcher, Robert Kraut, said he"s worried about the "opportunity costs" (机会成本) of so much
online time for youths. He found that teens who used computers, even just a few hours a week, showed
increased signs of loneliness and social isolation. "Chatting online may be better than watching television, but
it"s worse than hanging out (闲逛) with real friends," he said.
Today"s teens, however, don"t see anything strange in the fact that the computer takes up a central place in
their social lives, "School is busy and full of pressure. There"s almost no time to just hang out." said Parker Rice,
17. "Talking online is just catch-up time."
Teens say they feel good about what they say online or taking the time to think about a reply. Some teens
admit that asking someone for a date, or breaking up, can be easier in message form, though they don"t want
to do so. But they insist there"s no harm.
B. nothing is wrong with teens" chatting online
C. teens can manage their social connections
D. spending hours online does much good to teens
B. improve their school work
C. develop an interest in social skills
D. reduce their mental pressures
B. teens" computer skills and school work
C. the effects of the computer world on teens
D. different opinions on teens" chatting online
B. draw attention to teens" computer habits
C. suggest ways to deal with problem teens
D. discuss problems teens have at school
Research by a British biology student suggests that sharks could be used to predict storms.
Lauren Smith, 24, is close to completing her study on shark"s ability to sense pressure.
If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad
weather.
Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation
that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: "I"ve always been crazy about traveling and diving and this led me to an interest in sharks."
"I was delighted to have been able to research in the area for my degree. I know there"s so much more we
need to understand ---- but it certainly opens the way to more research."
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and
temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish----
none of which were harmed. She also used a special lab which can mimic (模拟) oceanic pressure changes
caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which
will give her the chance to enrich her experience of shark research.
B. a popular science magazine
C. a research paper
D. a personal diary
B. Sharks" behaviour can be controlled.
C. Michael Fish is not qualified for his job.
D. Lauren Smith will become a weather forecaster.
B. measuring the air pressure of weather fronts
C. recording sharks" body temperature
D. monitoring sharks" reaction to weather changes
B. A new research effort in predicting storms.
C. Biologists" interest in the secrets of sharks.
D. Lauren Smith"s devotion to scientific research.
totally unsuitable for human existence. People won"t have enough food supplies there, and the terrible
environment would make it impossible for them to live a long life. Besides, the journey won"t be safe. Can
anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement
of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is
another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there
will be a human colony (殖民地) on Mars. It will happen when people finally realize that two-way trips to the
red planet Mars are unnecessary. Most of the danger of space flight is in the launches (发射) and landings.
Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way
to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will be sent to
the new colony. Mars has all the materials for a colony to produce or make everything it needs, and Mars is
far more pleasant than the other planets in the outer space.

B. Humans will find Mars totally unsuitable for living.
C. Humans can produce everything they need.
D. Humans can live longer in the colony on Mars.
But if we consider the situation of the young people aged from eight to eighteen, we should think again.
What we often see nowadays is that young people juggle an ever larger number of electronic devices (电子
产品) as they study. While working, they also surf on the Internet, send out emails, answer the telephone and
listen to music on their iPods. In a sense, they are spending a significant amount of time in fruitless efforts as
they multitask.
Multitasking is even changing the relationship between family members. As young people give so much
attention to their own worlds, they seem to have no time to spend with the other people around them. They
can no longer greet family members when they enter the house, nor can they eat at the family table.
Multitasking also affects young people"s performance at university and in the workplace. When asked about
their opinion of the effect of modern gadgets (器具) on their performance of tasks, many young people gave
a positive response (反应). However, the response from the worlds of education and business was not quite
as positive. Educators feel that multitasking by children has a serious effect on later development of study skills.
They believe that many college students now need help to improve their study skills. Similarly, employers feel
that young people entering the job market need to be taught all over again, as modern gadgets have made it
unnecessary for them to learn special skills to do their work.
B. Take the place of.
C. Use at the same time.
D. Seek for information from.
B. family member do not greet each other
C. young people live happily in their families
D. young people seldom talk with their family members
B. Young people benefit a lot from modern gadgets.
C. Multitasking is an important skill to young people.
D. Young people must learn skills for future jobs.
B. following the natural time order
C. comparing opinions from different fields
D. presenting a cause and analyzing its effects
(独角兽). Descriptions of unicorns have been found dating from ancient times. The great philosopher
Aristotle theorized that there were two types of unicorn--- the so-called Indian Ass and the Oryx, a kind
of antelope. Unicorns are often used in the logo of a noble family, town council or university as their
special sign. Even Scotland is represented by a unicorn.
According to the legend, anyone attempting to catch a unicorn had to be extremely cautious as it has
a reputation for being very fierce. A clever trick suggested by unicorn-trappers, in order to catch this
magnificent beast without being hurt by its horn, was for the hunter to stand in front of a tree and then
to move quickly behind it as the unicorn charged. Hopefully, the creature could then be captured when
its horn was stuck in the tree.
When hollowed out and used as a drinking-cup, the unicorn"s horn was said to have the power to
offer protection against person. It was believed that nobody could be harmed-by drinking the contents
of a unicorn"s horn. Right up until the French Revolution in 1789, the French court was said to have used
cups made of"unicorn" horn in order to protect the king. In addition, the horn was said to have medicinal
value, so much so that it could be sold for more than ten times the price of the same weight of gold. What,
then, was "unicorn" horn? We know at times the rhino (犀牛) was confused with this legendary creature.
A drinking-cup supposedly made of"unicorn" horn was discovered to be made of the horn of a rhino.
B. Its horn was first used in France
C. It was similar to the Indian Ass and the Oryx
D. It could be the symbol of a university
B. making use of the tree as a protection
C. hiding quickly behind the unicorn
D. having the unicorn horn stuck in the tree
B. the users of the unicorn horn
C. the price of the unicorn horn
D. the comparison between the unicorn horn and the rhino horn
B. the unicorn does not exist in reality
C. the unicorn is the rarest animal in the world
D. the medicinal value of the horn is appreciated
