needs of man. The sea has provided man with food and a convenient way to travel to many parts of the
world. Today, nearly two-thirds of the world"s population lives within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources
on land are beginning to be used up. The sea, however, still can be hoped to supply many of man"s needs.
The list of riches of the sea yet to be developed by man"s technology is big. Oil and gas explorations
have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready
to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and
shellfish (贝类动物) is an ancient skill practised in the past mainly by Oriental people, including people
in Chin
a.Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm
temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and
waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong,
new materials has made this possible.
The technology to harvest the sea continues to improve.
Experts believe that by the year 2020 the problems that prevent us from exploiting (开发) fully the food, minerals, and energy sources of the sea
will be largely solved.
B. minerals and oil
C. warm temperature and ocean currents
D. the food, energy sources, and minerals
B. the sea, in the broad sense, has not yet been developed
C. the problems preventing our using the resources of the sea have already been solved.
D. by the year 2020, the technology will be good enough to exploit all the sea resources.
B. African people
C. European people
D. American people
B. Technology for Exploiting the Sea
C. Sea Harvest
D. Man, nature and the Sea

Kind-hearted parents have unknowingly left their chil
dren defenseless against failure. The generation born between 1980 and 2001 grew up playing sports where scores and
performance were played down because "everyone"s winn
er." And their report cards sounded more positivethan ever be
fore. As a result, Stanford University professor Carol Dweck, PhD, calls them "the overpraised generation."
Dweck has been studying how people deal with failure for 40 years. Her resear
ch has led her to find out two clearly different mind-sets that have a great effect on how we
react to it. Here"s how they work:
A fixed mind-set is grounded in the belief that tale
nt (才能) is genetic - you"re a bornartist, point guard, or numbers person. The fixed mind-set believes it"s sure to succeed
without much effort and regards failure as personal shame. When things get difficult, it"s
quick to blame, lie, and even stay away from future difficulties.
On the other hand, a growth mind-s
et believes that no talent is entirely heaven-sent and that effort and learning make everything possible. Because the ego (自尊) isn"t on t
he line as much, the growth mind-set sees failure as a chance rather than shame. When
faced with a difficulty, it"s quick to rethink, change and try again. In fact, it enjoys this
experience.
We are all born with growth mind-sets. (Otherwise, we wouldn"t be able to live in
the world.) But parents, teachers, and instructors often push us into fixed mind-sets by
encouraging certain actions and misdirecting praise. Dweck"s book, Mind-set: The
NewPsychology of Success, and online instructional program explain this in depth. But she
says there are many little things you can start doing today to make sure that your children,
grandchildren and even you are never defeated by failure.
B. They are often misunderstood.
C. They are eager to win in sports.
D. They are given too much praise.
B. cares a lot about personal safety
C. cannot share his ideas with others
D. can succeed with the help of teachers
B. Talent comes with one"s birth.
C. Scores should be highly valued.
D. Getting over difficulties is enjoyable.
B. Prevent them from making mistakes.
C. Guide them in doing little things.
D. Help them grow with praise.
A new review based on a research shows that stress affects the way the brain considers
the advantages and disadvantages, causing it to focus on pleasure and ignore the possible
negativeconsequences(results) of a decision.
The research suggests that stress may change the way people make choices.
"Stress affects how people learn," says Professor Mara Mather. "People learn better
about positive than negative outcomes under stress."
For example, two recent studies looked at how people learned to connect images with
either rewards or punishments. In one experiment, some of the participants were first
stressed by having to give a speech and do difficult math problems in front of an audience;
in the other, some were stressed by having to keep their hands in ice water. In both cases,
the stressed participants remembered the rewarded material more accurately(精确) and
the punished material less accurately than those who hadn"t gone through the stress.
This phenomenon is likely not surprising to anyone who has tried to resist eating cookies
or smoking a cigarette while under stress -at those moments, only the pleasure associated
with such activities comes to mind. But the findings further suggest that stress may bring
about a double effect. Not only are rewarding experiences remembered better, but negative
consequences are also easily recalled.
The research also found that stress appears to affect decision-making differently in men
and women. While both men and women tend to focus on rewards and less on consequences
under stress, their responses to risk turn out to be different.
Men who had been stressed by the cold-water task tended to take more risks in the
experiment while women responded in the opposite way. In stressful situations in which
risk-taking can pay off big, men may tend to do better, when caution weighs more,
however, women will win.
This tendency to slow down and become more cautious when decisions are risky might
also help explain why women are less likely to become addicted than men: they may more
often avoid making the risky choices that eventually harden into addiction.
B. recall consequences more effortlessly
C. make risky decisions more frequently
D. learn a subject more effectively
B. preference for pleasure
C. tolerance(容忍) of punishments
D. responses to suggestions
B. men have a greater tendency to slow down
C. women focus more on outcomes
D. men are more likely to take risks
diseased kidney from a woman.What"s so unusual about that?David Nichol was in his
office in Australia while the woman lay on an operating table in New Zealand.
What connected them was a technology called remote surgery(手术).
Remote surgery itself is not new.In 2001,a group of doctors in New York,US,removed
a gall bladder (胆囊)from a patient lying in France.It was the first successful case of remote
surgery used on a human across international borders.
Now,Nichol"s operation is to be the first one performed on the kidneys.Nichol used
joysticks (操纵杆)to direct robotic arms in the New Zealand operating room during
the two-hour operation.The joysticks and the robotic arms are linked by a computer
network.Nichol could watch the robot"s work while doctors in New Zealand checked
the patient and changed the instruments as needed."Before this technology,I would have
been in the operating theatre (手术室)when they were performing the operation," Nichol
said.During remote surgery,the doctor is the one in control.The robots carry out the
operation using a complex method.
Doctors have found that a robot is better than a human surgeon at carrying out this
difficult operation—even when it is controlled thousands of miles away.Unlike humans,
robotic "arms" do not shake when they target a small piece of tissue (组织)or organ.In
remote surgery such as the removal of kidney stones,the robotic arm inserts a long special
needle into the patient"s body and X-rays guide it to the kidney.
Once the robotic arm has reached the hard kidney stone,the needle gets wider so that
a tiny telescope can travel down it and look at the organ.Then instruments are used to
break up the stone and get rid of the remaining waste.
For doctors,the technology means less stress in the operation room.And for patients,it
means far less chance of suffering blood loss or damage to a nearby organ.
However,the remote surgery is not widely used because it"s still very expensive.A remote
operation on a gall bladder costs more than US $1 million.A normal operation costs US
$2000.It will be some time yet before the price falls and the operation is available to people
throughout the world.
B.it as a robot that was carrying out the operation
C.the patient and the doctor in control were in different countries
D.it was the first successful operation of remote surgery performed on kidneys
B.cure
C.meet with
D.get close to
A.The joysticks.
B.The robot.
C.The network.
D.The doctor. .
B.It is more convenient for doctors to perform the operations.
C.The patients will have less chance of suffering blood loss or damage to a nearby organ.
D.The robot is better than a human surgeon
A study suggests certain vegetables such as broccoli(西兰花)and spinach(菠菜)might help older
women keep their minds sharp.
Researchers have discovered that women in their 60s who eat more green leafy vegetables how less
signs of mental decline over time, reported Wednesday"s CRI online.
They gave participants a bundle of tests measuring memory, oral ability and attention. The study
didn"t include men, but researchers say a similar diet would likely have the same results.
Eating fish can cut risk of heart rhythm disorder
US scientists have found that eating fish can reduce the risk of deadly heartbeat disorders. They say
baked fish can effectively reduce the risk of atria fibrillation(心房颤动)among older men and women,
reported Tuesday"s CRI online.
Researchers say in their 12 years of research among 4,800 people over the age of 65, they found
those who ate fish one to four times per week had an about 30 percent lower risk compared with those
who ate fish less than once a month. They say the omega-3 fatty acid can reduce the risk of a range of
heart disorders and is vital to brain development and function.
Red wine may extend life
US scientist have found that a mixture that makes red wine a healthy drink may also hold the secret
to a longer life. They say antioxidant(抗氧化剂) in wine acted on fruited flies and worms in the same
way as a method known to extend the life of many animals, which is by sharply limiting how much they
eat.
Limiting calories has been shown to make animals such as dogs and monkeys live longer, but they
are often tired and lose productivity. The researchers will begin testing the mixture in mice.
Every year, our school has a dance for all the students.It"s a little funny seeing friends in clean shoes
and trousers or colorful_1_, instead of the usual school uniform.
Most of us think the dance is great_2_-even the teachers enjoy being there._3_, two weeks ago
someone said that there would be no4__band this year-only CDs.
"I don"t _5_it!"Amy cried out during the lunch break. "Someone said the school couldn"t_6_a band,
and they think it"s too noisy anyway, "added Daniel.
"Well, I don"t think it"s_7_enough without a band!"declared Angela, "and I"m going to see what can
be done."
Angela was as good as her_8_.In the afternoon she went to see the school headmaster who agreed
to give the_9_some more thought.And he suggested that one 10 for having a band was to increase the
price of each ticket from $ 5 to $10.Angela had to 11 out whether the students would like to do that.
"I need all of you to help me, "she 12
to our group before school the next day."Mr Berry gave me alist of all the names, and suggested we ask each one their 13 about the band and the extra cost."
14 the day we asked around as Angela suggested, and wrote down people"s feelings about the
band and the cost.We were amazed how much 15 there was for the band and everyone agreed to pay
the extra $ 5.
"I"m surprised, "smiled Mr Berry, when we gave him the 16 ."I really thought that only a few people
17 their band and that the cost would be too high.OK.Angela, your next 18 is to find a good band
and line them up for the dance."
Angela was all smiles and 19 the news to Amy and Daniel."You"re 20 , "smiled Daniel to Angela
as he thought how close they came to having a less than perfect dance.
