Robots are common in today's world. They manufacture cars, work in space, explore oceans, clean up oil spills and investigate dangerous environments. And now, scientists at the University of Manchester are using a robot as a laboratory partner.
The researchers at the university created the robot in 2009 and named it Adam. Despite the name, Adam is not a humanoid robot. It is about the size of a car.
Adam was built to do science and make discoveries. Ross King is the leader of the University of Manchester research team. He says the robot made a discovery about yeast(酵母), a kind of fungus(真菌) used in science as a model for human cells.
"Adam hypothesized certain functions of genes within yeast and experimentally tested these hypothesizes and confirmed them. So it both hypothesized and confirmed new scientific knowledge."
Adam's success as a scientist led to the creation of another robot scientist named Eve. Researchers developed Eve to design and test drugs for tropical and neglected diseases. These diseases kill and infect millions of people each year.
Drug development is slow and costly. Experts say it can take more than 10 years and about $1 billion to discover and develop new medicines. Drug manufacturers are unlikely to get their investment money back.
So the University of Manchester developed a low-cost test that shows whether or not a chemical is likely to be made into an effective medicine. Mr. King says that other drug testing methods were not very effective.
"How it works conventionally is you use robotics as well and you have a large collection of possible drugs. You test every single compound. And you start at the beginning of your library and continue until the end, and stop. So it's not a very intelligent process. The robotics doesn't learn anything as it goes along, even if it's tested a million compounds, it still doesn't have any expectation of what will happen next when it tests a new compound."
Mr. King says that Eve is different because the robot learns as it tests different compounds. He says the robot is designed to ignore compounds that it thinks unlikely to be good. It will only test the compounds which have a good chance of working.
Eve has discovered that a compound known to be effective against cancer might also be used to fight against malaria and other tropical diseases.
Mr. King says he hopes to completely automate the drug testing process with robots like Eve to create and test new chemicals. But he says humans remain in control of the manufacturing process.Scientists now are using a robot to__________.

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course. the teens see it in exactly the same way, except oppositely. Both feel trapped
In this article. I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right, It doesn’t matter what the topic is –politics. The taws of physics, or the proper way to break an egg –the point of these arguments is to prove that you are right and the other person is wrong. for both wish to be considered an authority—someone who actually knows something —and therefore to command respect. Unfortunately, as long as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progressWhy does the author compare the parent-teen war to a border conflict?

What does the underlined part in Paragraph 2 mean?
| A．The teens blame their parents for starting the conflict. |
| B．The teens agree with their parents on the cause of the conflict |
| C．The teens cause their parents of misleading them |
| D．The teens tend to have a full understanding of their parents |
Parents and teens want to be right because they want to ________.
| A．give orders to the other |
| B．know more than the other |
| C．gain respect from the other |

It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.
My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’m so glad I did.
On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all，it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby. We couldn’t believe it ——there aren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale——actually as big as our boat——was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools(漩涡) and waves. ”She’s trying to help her baby, but on the wrong side, ”my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, some-times rising from the water right beside us to breathe——and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day, Nearly four decades later, I still look back fondly to that golden day at sea.The author says “I’m so glad I did. ”(in Para. 2)because __________.

How words came into being is unknown.All we assume is that some early men invented cortain sounds,in one way or another,to express thoughts and feelings,actions and things,so that they could talk with each other.Later they agreed upon certain signs,called letters,which could be put together to show those sounds,and which could be written down.Those sounds,whether spoken or written in letters,are called words.
The power of words,then,lies in their associations-the things they bring up to our minds.Words become filled with meaning for us by experience;and the longer we live,the more certain words bring back to us the happy and sad events of our past;and the more we read and learn,the more the number of words that mean something to us increases.
Great writers are those who not only have great thoughts but also express these thoughts in words which have powerful effects on our minds and feelings.This clever use of words is what we call literary style.Above all,the real poet is a master of words.He can express his meaning in words which sing like music,and which by their position and association can move men to tears.We should therefore learn to choose our words carefully and use then correctly,or they will make our speech silly and common.We learn from the text that language might have begun with( )

Thousands of people living in the Chinese eapital will celebrate the start of the Chinese New Year by heading for the ski resorts(滑雪场).Never mind that Beijing’s dry weather seldom produces now. It is cold enough in winter for snow-making machines to make a covering for the hills north to the capital. And the rapid growth of a pleasure-seeking middle class has formed the basis for this New craze(热潮).
Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed an astonishing increase.There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr.Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts in Europe.
Beijing’s sking craze is partly a result of the recent increase in private(私有的)cars. This has led to the growth of a leisure industry in the capital’s suburbs(郊区).which until the late-1990s were unreachable to ordinary people. According to Mr. Wei,About 40％ of the visitors to his resort some in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money.Starting ski resorturequires quite a lot of money:hiring land from the local government,preparing the hills,buying snow machines,making sure there are enough water and electricity to run them,and buying ski equipment for hiring out to customers.The ski resort where Mr.Wei works cost nearly $4m to set up.And,as so often in China when someone comes up with a good idea,many others rush in and price wars break out.Beijing now offers some of the cheapest ski training classes in the world,though with most people rather new to the sport, expecting a few more doing the same job.What does this text mainly talk about?
| A．Convenience for skiers brought about by private cars |
| B．Skiing as a new way of enjoying one’s spare time |
| C．Things to be considered when starting a ski resort |
| D．A sudden increase of ski training classes in Beijing |
Why are some Chinese likely to go skiing in Burope?
| A．To visit more ski areas |
