阅读理解。     Space travel is definitely bad for astronauts" bones, reducing their bone density(密度)
after only a month of weightlessness, according to French research published on Friday.
     Laurence Vico and his fellow workers at St Etienne University called for more research
into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station
showed bone loss continued throughout space flights.
     "Bone loss was especially striking in four astronauts, " the scientists reported in the Lancet
Medical Journal.
     They measured the bone mineral density (BMD) of bones in the forearm(前臂) and
lower leg of the astronauts who had spent one to six months in space.
     The BMD loss was significant in the tibia(胫骨) of the lower leg, a weight-bearing bone,
but barely changed in the radius(桡骨) of the forearm. "Our results indicate the need to
investigate not only different bones, but also different areas of the same bone since not all
sites of the skeleton (骨架) are similarly affected by space conditions, " they added.
     Without gravity the body isn"t bearing any weight so there is no need for calcium (钙)
which makes bones strong, and it becomes empty into the bloodstream.
     The research team suggested in future scientists should try to determine if the loss of bone
density was only on weight-bearing bones on longer flights, also the possible recovery after
returning to Earth.1. French scientists did their research on Russian astronauts, because _______.A. they only cared for the Russian astronauts
B. they were not interested in their own astronauts
C. the Russian government invited them to do their research
D. the Russian astronauts worked in space for a period of time2. Scientists have found that _______.A. the BMD loss may cause serious illness to astronauts
B. the BMD loss may cause some change in astronauts" bodies
C. astronauts shouldn"t care about the BMD loss
D. astronauts should take some calcium before space travel3. What cause the BMD loss to astronauts, according to this passage?A. The food they eat in space.
B. The drinks they take in space.
C. The temperature in space.
D. The gravity in space.4. In the third paragraph, the underlined word "striking" means ______.A. unusual
B. simple
C. weak
D. slow

阅读理解      Monkeys are very similar to us in many ways. Most have ten fingers and ten toes, and brains
much like ours. In fact, Charles Darwin"s theory of evolution says that monkeys and humans share
a common ancestor. We enjoy watching them because they often act like us, and we also love to
use many expressions about monkeys in almost every language This is why many monkey expressions
are about tricky people or playful acts.
      Monkeyshine is one of these expressions to show tricks or foolish acts. The meaning is clear if
you have ever watched a group of monkeys playfully chasing each other:pulling tails, stealing food,
doing tricks.
Monkeying around with something means that you do not know what you are doing. When you feel
like doing something but have no firm idea of what to do, you are monkeying around. It is just a way
to pass the time.
      Monkey business usually means secret, maybe illegal activities You may come across a news
report that there is monkey business involved in building the new airport, with some officials getting
secret payments from builders.
     Monkey suits are common names for clothes or uniforms soldiers wear. In earlier years in many
American cities, you would find men playing musical hand organs on the street. Dancing to the music
would be the man"s small monkey that was dressed in a tight-fitting, colorful jacket similar to a military
uniform. So, people began to call a military uniform a monkey suit. 1. Which of the following is NOT true about the similarities between humans and monkeys?A. Most monkeys have ten fingers and ten toes.
B. Monkeys have the same brains as humans.
C. Monkeys often act like humans in many ways.
D. Monkeys are humans closest relatives in species. 2. According to the passage, an idle wander(徘徊)on the street can he described as        A. monkeyshine
B. monkeying around
C. monkey suit
D. monkey business3. Monkey suits are commonly used to call military uniforms because they        .A. are created particularly for soldiers" uniforms
B. are originally designed for American soldiers
C. share typical features with military uniforms
D. make American soldiers look like monkeys4. Most monkey expressions are            .A. used only in western cultures
B. used on some formal occasions
C. about tricks and naughtiness
D. about terrible funny behaviors

阅读理解     Man, a land animal. But he is also closely tied to the sea. Throughout history the sea has served the
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 China.
    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.1. The major things that the sea offers man are _________.  A. fish and oil
B. minerals and oil
C. warm temperature and ocean currents
D. the food, energy sources, and minerals2. We can conclude from this passage that _________.   A. the sea resources have largely been used up
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.3. The underlined words "Oriental people" in the fourth paragraph probably mean _________.A. the people in Asia
B. African people
C. European people
D. American people4. The best title for this passage is _________. A. Sea Food
B. Technology for Exploiting the Sea
C. Sea Harvest
D. Man, nature and the Sea

阅读理解。                                          Make Up Your Mind to Succeed
     Kind-hearted parents have unknowingly left their children defenseless against failure. The
generation born between 1980 and 2001 grew up playing sports where scores and
performance were played down because "everyone"s winner." And their report cards
sounded more positivethan ever before. 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 research
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 talent (才能) is genetic - you"re a born
artist, 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-set 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 New
Psychology 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.1. What does the author think about the present generation?_____.A. They don"t do well at school.
B. They are often misunderstood.
C. They are eager to win in sports.
D. They are given too much praise.2. A fixed mind-set person is probably one who ______ .A. doesn"t want to work hard
B. cares a lot about personal safety
C. cannot share his ideas with others
D. can succeed with the help of teachers3. What does the growth mind-set believe?_______.A. Admitting failure is shameful.
B. Talent comes with one"s birth.
C. Scores should be highly valued.
D. Getting over difficulties is enjoyable.4. What should parents do for their children based on Dweck"s study?______A. Encourage them to learn from failures.
B. Prevent them from making mistakes.
C. Guide them in doing little things.
D. Help them grow with praise.

阅读理解。                                           Decision-making under Stress
     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.1.We can learn from the passage that people under pressure tend to ______.A. keep rewards better in their memory
B. recall consequences more effortlessly
C. make risky decisions more frequently
D. learn a subject more effectively2.According to the research, stress affects people most probably in their ______.A. ways of making choices
B. preference for pleasure
C. tolerance(容忍) of punishments
D. responses to suggestions3. The research has proved that in a stressful situation, ______.A. women find it easier to fall into certain habits
B. men have a greater tendency to slow down
C. women focus more on outcomes
D. men are more likely to take risks

阅读理解。     Last Monday,David Nichol,Australia"s top kidney (肾)doctor,successfully removed a
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. 1.Why was this kidney operation so unusual?Because ________. A.remote surgery was only used on the kidney operation
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  2.What does the underlined word "target" mean in this passage?   ______.A.aim at
B.cure
C.meet with
D.get close to  3.What is the key part of the operation of remote surgery?   ______.

A.The joysticks.
B.The robot.
C.The network.
D.The doctor. .

4.What advantage do the operations of remote surgery have mainly?______.A.The doctors are less stressed during the operations.
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
