Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day.
We realized a long, long time ago that nature provides the best blueprint for invention. We’ve borrowed canals from beavers and reflectors from cat’s eyes. Although the words “bionics”(仿生学) became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(档案) don’t go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.
To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright’s pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter .
Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic(简单抽象艺术) structure. On the other hand, Barney Connett’s fish submarine actually looks like a fish.
Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(蚂蚱)-sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.
“Cats”, “monkeys” and “giraffes” mentioned in paragraph 1 are examples to show______.

A．they are highly-evolved species as humans

B．animals have skills that humans do not possess

C．humans can learn animals’ skills

D．they are skillful in different ways

What happened after the Wright brothers’ success?

A．People carried out a systematic study on pigeons.

B．People studied more animals and plants to develop the airplane.

C．People could fly their airplane for fun.

D．People kept their airplane at a French gallery.

Which of the following is true about the research carried out by the US Army?

A．It has cost a large sum of money.

B．It has changed our life.

C．It has improved the abilities of tanks

D．It has not succeeded yet.

What does the writer want to tell in the passage?

A．many inventions get ideas from nature.

B．Some animals possess unique skills.

C．People should protect nature.

D．Bionics is far from perfect

Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s．Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women．Right? Wrong．Men and women always score similarly on intelligence tests, despite the difference in brain size．Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain．The brain consists of “grey matter” and “white matter”．While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes．
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women．This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time．When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time．
There are other important differences between two sexes．As white matter is the key to spatial（空间的） tasks, men know better where things are in relation to other things．“A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher．That may explain one of life’s great mysteries: why men refuse to ask for directions…and women often need to!
The differences begin when fetuses（胎儿） are about nine weeks old, which can be seen in the action of children as young as one．A boy would try to climb a barrier （障碍物） before him or push it down while a girl would attract help from others．These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills．It may all go back to our ancestors（祖先）, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research．
If all this disappoints you, it shouldn’t．“The brain changes throughout our lives according to what we do with it．” says a biologist．
56．The passage mainly tells us ________．
A．the difference between men’s and women’s brains
B．the changes in brain throughout our lives
C．that men are better at spatial tasks
D．that brain differences are related to our ancestors
57．Which of the following is true according to the first paragraph?
A．Women’s brain is 10% less than men’s
B．Grey matter plays the same role as white matter．
C．Grey matter controls thinking in the brain．
D．Both sexes have the same amount of white matter．
58．What can we infer from the second and third paragraphs?
A．Women prefer doing many things at a time．
B．Men do better dealing with one job at a time．
C．Women do not need to tell directions．
D．Men have weaker spatial abilities．
59．Which of the following do you agree with according to the fourth paragraph?
A．Young boys may be stronger than young girls．
B．More women take up jobs requiring speech skills
C．Women may have stronger feelings than men．
D．Our ancestors needed more spatial skills．

The meaning of the word “volunteer” may be a little different in different countries, but it usually means “one who offers his or her services．” There are many different ways in which people can volunteer, such as taking care of sick people, working in homes for homeless children, and picking up garbage from beaches and parks．Volunteers may work within their own countries or in other countries．They are often people with a strong wish to help those who are less fortunate than themselves．Volunteers don’t expect any kind of pay．
At the root of volunteering is the idea that one person may have the ability to offer services that can help other people．Tracy, a good friend of mine, however, recently came back from India with a new idea of what being a volunteer means．She worked for two and a half weeks in one of Mother Teresa’s homes in Calcutta．The following is her story．
“I first heard about Mother Teresa in my high school．We watched a video about her work in India and all over the world．I was so moved by her spirit to help others and her endless love for every human being that after I graduated from high school, I too wanted to try her kind of work．So with two friends I flew to Calcutta for a few weeks．”
“I was asked to work in a home for sick people．I helped wash clothes and sheets, and pass out lunch．I also fed the people who were too weak to feed themselves and tried to cheer them up．I felt it was better to share with them than to think that I have helped them．To be honest, I don’t think I was helping very much．It was then that I realized that I had not really come to help, but to learn about and experience another culture that helped improve my own understanding of life and the world．”

The common cold is the world’s most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread fallacy(谬误) of all is that colds caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.
In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter？Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms(症状).
51. The writer offered _______ examples to support his argument.
A. 4            B. 5              C. 6              D. 3
52. Which of the following does not agree with the chosen passage?
A. The Eskimos do not suffer from colds all the time.
B. Colds are not caused by cold.
C. People suffer from colds just because they like to stay indoors.
D. A person may catch a cold by touching someone who already has one.
53. Arctic explorers may catch colds when _______.
A. they are working in the isolated arctic regions
B. they are writing reports in terribly cold weather
C. they are free from work in the isolated arctic regions
D. they are coming into touch again with the outside world
54. Volunteers taking part in the experiments in the Common Cold Research Unit _______.
A. suffered a lot                             B. never caught colds
C. often caught colds                 D. became very strong
55. The passage mainly discusses _______.
A. the experiments on the common cold
B. the fallacy about the common cold
C. the reason and the way people catch colds
D. the continued spread of common colds
