U.K. astronomer Martin Rees says that in future, some people may decide to leave Earth in order to live on other worlds. Finally, he added, they might use high technologies to change themselves to adapt to their new environment.
“They will find themselves ill-adapted to conditions there, so they will redesign themselves using powerful genetic engineering (基因工程) technologies,” Rees says. “These techniques will, I hope, be kept under control on Earth; but those on other planets will be freer to try.”
“We should surely wish them luck in changing their children to adapt to outer planets. This may be the first step towards the development of a new species,” says Rees. He says that these “post-humans” could one day turn into “fully inorganic intelligences” which may not even need an atmosphere to live and may grow well in zero-gravity environments, which ordinary people are not adapted to. “So it is in deep space, not on Earth, that ‘brains’ may develop powers that humans can’t even imagine,” says Rees.
Rees also warns that human beings shouldn’t fall back on the idea that they can avoid disaster on Earth by heading deeper into space. “It’s dangerous to think that space offers an escape from Earth’s problems,” he says. “We must solve them here. Dealing with climate change is a doddle compared with changing other planets; there’s no environment in our solar system as mild as even the top of Qomolangma.”
This isn't the first time Rees has made interesting predictions. Last year, Rees predicted possible dangers of nuclear physics (核物理学) tests taking place on Earth. “Maybe a black hole could form, and then take in everything around it,” he said. However, some scientists were not worried about this prediction. Stefan, a physicist, said he wouldn't be “losing any sleep” over that prediction.
1.What might be Rees’s prediction?
A.People might live on other planets soon.
B.Space technologies might be improved greatly.
C.People might avoid using genetic technology in outer space.
D.Space exploration might lead to genetically-changed humans.
2.Which of the following might be a description of “post-humans” ?
A.They have better survivability.
B.They are sensitive to zero gravity.
C.They are as smart as ordinary people.
D.They cannot adapt to the global environment.
3.What might the underlined part “a doddle” Paragraph 4 mean?
A.The top dog. B.A hot potato.
C.A piece of cake. D.A white elephant.
4.What did Stefan think of Rees’s prediction?
A.It was doubtful.
B.It made great sense.
C.It required special attention.
D.It questioned many popular beliefs.

Some people are pessimistic (悲观) when they think about the future. They say that, a hundred years from now, we will have used up most of the earth’s resources. We will have polluted our sea badly, and be unable to eat fish from it. We will have made air so dirty that we will need to wear masks. The world’s pollution will have doubled, and we will have used all the countryside for housing; there will be no farmland left.
Other people believe that man adapts very easily. They have a different idea of the future. However, in their views, will people be living in a hundred years’ time?
One architect believes that man will move off the land. He suggests that the city of the future will be a huge, pyramidshaped building, which will be floating on the surface of the sea. About 5,000 families will be living there, and the building will contain shops and schools as well as homes. By living on the sea, we will give the farmers more land to grow crops.
As for oil, people will no longer need it: we will be heating our homes with power from the sun. And we will not be short of minerals, because there are plenty under our oceans. At the moment, we do not have the technology to get them out. But, in a hundred years’ time, the optimists (乐观者) say, the new sea cities will be using these resources.
What will be in the shops in the year 3000? What will people be wearing? How will people be traveling?
Scientists who make predictions about the future suggest that, by the year 3000, shops will no longer exist. Computers will have replaced them; and people will order goods from home.
People will be wearing very light, thin clothes. By this time, scientists will have invented a fabric that keeps us cool in hot weather and warm in cold weather.
As for travel, the experts say that most people will be using public transport. Electric cars will be traveling through the streets day and night. Anybody will be able to stop one and use it.
An interesting picture! Unfortunately, we will not be there if these predictions come true.
1.Pessimists believe that in the future ________.
A. seas and oceans will be full of houses
B. we’ll have used up most of the resources
C. we will have not enough fish to eat from the seas
D. we will have polluted the air not so badly that it will be possible for us to breathe
2.Scientists have made the predictions EXCEPT ________.
A. electric cars will be going along the streets continuously
B. the resources under the oceans will never be used up
C. people will order goods from home
D. people won’t suffer from cold any longer
3.What does the underlined word in the seventh paragraph refer to?
A. a kind of tool B. a kind of energy
C. a kind of cloth D. a kind of resource
4.We can learn from the article that ________.
A. we should be optimistic about the future
B. we should be pessimistic about the future
C. we shouldn’t think too much about the future
D. we have no idea of what will happen in the future

What will city life be like in the future? Some people think that life in the cities is going to be horrible. They say that cities will become more and more crowded. As the number of people increases, there will be less space for each person. This overcrowding will cause other problems — more crime, dirtier streets , and worse problems with traffic than we have now. How will people find enough drinking water, energy (such as gas and electricity ), and housing? Because life will be hard, people who live in cities will worry more, and they may become sick. For these reasons, some say that nobody will want to live in city areas.
How can we deal with such problems as overcrowding, crime, and traffic? In some cities, thousands of people are already sleeping in the streets because there is little suitable housing — and because houses are too expensive. The crime rate isn’t going down. Instead, it is increasing so fast that many people are afraid to go out at night. Traffic is also getting worse. More and more often, traffic jams are so bad that cars don’t move at all for several streets. These problems have been getting worse, not better, so many people see no hope for the future of the city.
Los Angeles, California, for example, has no subway system and buses are slow. Instead, many commuters (乘、开车上班族) drive many miles from their homes to work. Many of these drivers spend several hours each day on busy freeways. New York, however, has a big transit system — buses, commuter trains, and subways. Because the public transportation is crowded and dirty, many people drive private cars, and the traffic jams are worse than that in Los Angeles. A taxi driver complains, “I was driving home, but in forty-five minutes I moved only two miles! Finally, I turned off the engine and just sat there. A lot of people left their cars where they were in the middle of the street and went into a bar for a few beers!”
On the other hand, some cities have clean, fast and pleasant public transportation systems. In Paris, France, and Toronto, Canada, for example, anyone can use buses or subways to move quickly from one part of the city to another.
1.What do some people think is the main problem of the future city like?
A. Poor housing. B. Overcrowding.
C. Environmental pollution. D. Traffic jams.
2.The best way to work out the traffic problem in Los Angels might be _________________.
A. cutting down the number of private cars
B. providing more buses in the freeway
C. building a subway system
D. persuading people to live nearer to their workplaces
3.Which of the following sentences is NOT TRUE?
A. Thousands of people are already sleeping in the streets.
B. The crime rate isn’t going down.
C. The traffic jams are so bad that cars don’t move at all for several streets.
D. Many people have a positive attitude towards the future of the city.

Some people like modern art, while others say that is rubbish. But a cleaner who works in the Tate Gallery in London isn’t able to tell the difference. The woman, whose name isn’t known, mistook a work of art by the German painter Gustav Metzger for a bag of rubbish, and threw it out with other bags. The plastic bad, which contained pieces of paper and cardboard, was later recovered outside the gallery, but the artist thought that it was too damaged to be put on show again. 78-year-old Mr Metzger explained that the exhibit, which he said was a copy of a similar work he had created in 1960, was meant to show that all art is temporary and “finite”(有限的).
Embarrassed officials at the museum said that they had had to call a meeting with cleaners to explain which things should not be touched. They would not say whether Mr Metzger would be paid any compensation for the incident. However, to make absolutely sure the same thing would not happen again, they decided to cover Mr Metzger’s work every evening with a colored cloth. In this way the cleaners arriving after the gallery had closed to the general public would realize they should not touch it.
This is not the first time that museum cleaners have had trouble distinguishing exhibits from rubbish. In 2001, in another London gallery, a cleaner threw away a work by the well-known British artist Damien Hirst. It was an arrangement of empty beer bottles, coffee cups, and overflowing ashtrays, which were meant to indicate the chaos in the life of an artist.
However, cleaners don’t always throw things away—sometimes they clean them! This was the case with a dirty asking what the bath was doing in the gallery, the cleaners simply scrubbed it clean.
1.What’s the best title of the passage?
A. Cleaners mistake modern art for rubbish
B. Modern art shouldn’t be cleaned
C. What makes a great work of art
D. Cleaners don’t always throw things away
2.Which of the following is not true?
A. People have different opinions on modern art
B. Mr Metzger would be paid much compensation
C. A work of Damien Hirst was thrown away by a cleaner in 2001
D. Some modern work is about artists’ chaos of their life
3.The last paragraph is written to show that____________.
A. cleaners often make exhibits as clean as possible
B. cleaners can’t always differ exhibits from rubbish
C. exhibits are usually difficult to clean
D. exhibits are not always so beautiful

It seems some people have something bad to say about Facebook, the social media website that now has attracted more than 300 million members. To them I have only this to say: Stop please!
A recent article in the Wall Street Journal blamed Facebook’s ability to ruin friendships, saying that it limits communication to typing and encourages people to spend far too much time with friends they have never met.
Having used Facebook since its first year, I find these arguments false. The simple truth is that the problems are only a symptom of Facebook abuse. Like many things, it is only as harmful to your life and relationships as you allow it to be. Consider arguments against watching too much TV and overeating.
Try using Facebook to find friends who may have long ago changed their e-mail addresses and phone numbers, to find out what your old college friends are up to, to congratulate your friends on their latest birthdays, to share pictures and articles you find interesting, and to join in the discussion about them with your friends.
Sure, I had days when I wasted a little more time on Facebook than I should, but I’m not going to blame Facebook for my own laziness. If Facebook wasn’t there, I would have found something else to waste time on. To my “friends”: if you don’t feel like broadcasting your life stories on your Facebook, don’t. If you tire of my personal updates, ignore them. If you don’t want to join in the popular online games, don’t. It is a fun tool at your fingers that can be used for both good and bad. If you don’t like using Facebook, don’t.
I am now a consultant at the Department of State. I use Facebook to keep in touch with friends, family, and colleagues who live and work all over the world.
1.Why did the article in the Wall Street Journal blame Facebook?
A.Because it makes people spend too much time online.
B.Because it can make people lose their real-life friends.
C.Because it is as harmful to people’s lives as watching TV.
D.Because it encourages people to make friends with strangers.
2.What does the author suggest using Facebook to do?
A.To find out lost e-mail addresses and phone numbers.
B.To arrange appointments with our old college friends.
C.To collect interesting pictures and articles from our friends.
D.To keep in touch with friends who we haven’t called for long.
3.We can imply from the passage that by using Facebook we can ____.
A.read other’s personal updates
B.write our life stories online secretly
C.decide who can read our life stories
D.refuse to join in popular online games
4.The author writes the last paragraph to ____.
A.prove that Facebook can be well used
B.gain support from the Department of State
C.show that Facebook is used all around the world
D.introduce how she uses Facebook in her work as a consultant

Some people state they never forget a face. But what does that saying mean? Is there really no limit to the number of faces a person can remember?
A new study has found that, on average, people can remember as many as 5,000 faces. That number comes from a group of researchers at the University of York in England, There have been many studies recently on facial recognition. But the authors of this study say theirs is the first time that scientists have been able to put a number to the abilities of humans to recognize faces.
During the study, people spent one hour writing down as many faces from their personal lives as possible, Then, they wrote down famous faces they know, such as actors, politicians and other public people. The results showed that the participants knew between 1,000 and 10,000 faces, which is very shocking to the researchers. Rob Jenkins, coauthor of the study, said one explanation about it may be that some people have a natural ability for remembering faces. He also said it could be because of different social environments. Some people may have grown up in more populated places. So they may have had more social contact throughout their lives.
The ability to tell individual people apart is “clearly important.” In today’s modern world of big cities, televisions and social media, we meet thousands of people. Our facial recognition abilities help us to deal with the many different faces we see on the screens, as well as those we know.
The people in the study included 25 men and women. They are between 18 and 61 years old. “It would be interesting to see whether there is a peak age for the number of faces we know”, Jenkins said it is possible that we gather more faces throughout our lifetime. But, he added, there also may be an age at which we start to find it harder to remember all of those faces.
1.How is the study different from the previous ones?
A. It is the first study on facial recognition.
B. The study includes participants of all ages.
C. It lists the number of faces people can recognize.
D. Participants could only recognize faces from personal lives.
2.What does the underlined word “it” in Paragraph 3 refer to?
A. The difference of social environments.
B. People’s natural ability to learn.
C. The wide range of the numbers.
D. The necessity of facial recognition.
3.What will the researchers probably focus on after this study?
A. Why older people remember more faces.
B. When people can remember the most faces.
C. Whether people’s ability to remember faces is necessary.
D. How our ability to remember faces vary at different ages.
4.What can be a suitable title for the text?
A. Human Beings Never Forget a Face
B. Face Recognition Benefits Humans
C. The Key to Remembering More Faces
D. The Brain Remembers Thousands of Faces

Some people are so rude!
Who sends an email or a text message that just says “Thank you”? Who leaves a voice mail message rather than texts you? Who asks for a fact easily found on Google? Don’t these people realize that they’re wasting your time?
Maybe I’m the rude one for not appreciating life’s little politeness. But many social agreed standards just don’t make sense to people drowning in digital communication.
In texts, you don’t have to declare who you are or even say hello. Email, too, is slower than a text. Voice mail is a now impolite way of trying to connect.
My father learned this lesson after leaving me a dozen voice mail messages, none of which I listened to. Exasperated, he called my sister to express his dissatisfaction that I never returned his phone calls. “Why are you leaving him voice mail?” my sister asked. “Just text him.”
In the age of the smartphone, there is no reason to ask onceacceptable questions about: the weather forecast, a business’s phone number, or directions to a house, a restaurant, which can be easily found on Google Maps. But people still ask these things. And when you answer, they respond with a thankyou email.
How to handle these differing standards? Easy. Consider your audience. Some people, especially older ones, appreciate a thankyou message. Others, like me, want no reply.
The anthropologist (人类学家) Margaret Mead once said that in traditional societies, the young learn from the old. But in modern societies, the old can also learn from the young. Here’s hoping that politeness never goes out of fashion but that timewasting forms of communication do.
1.What does the underlined word “Exasperated” mean in the fifth paragraph?
A.Worried. B.Surprised.
C.Annoyed. D.Tired.
2.Why didn’t the writer reply to his father?
A.He liked text messages better.
B.He enjoyed checking his voice mail.
C.He didn’t receive any voice mail messages.
D.He didn’t want to talk with his father.
3.Which of the following does the writer agree to?
A.People needn’t learn from one another in traditional societies.
B.Dealing with voice mail should vary with each individual.
C.People needn’t turn to Google for help when in trouble.
D.Declaring who you are or saying hello in texts is necessary.
4.What’s the best title for this passage?
A.Nowadays: what should we do with text messages?
B.Nowadays: do you like leaving others a voice message?
C.Nowadays: what means should we use in communication?
D.Nowadays: do you need a thankyou message?
