NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people’s memories are affected.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war.
They say that there are many people who suffer from terrible memories.
"Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
But those who are against the research say that maybe the pills can change people’s memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past.
"All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.

The way we get about has a deep influence on the way we live－affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true?
Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演員) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.
The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus.

Conservationists have unveiled plans to preserve and protect the world's most important species of coral, in a response to increasing threats that they say will lead to "functional extinction" within decades．
Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct．The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity（酸性）, overfishing and pollution．
The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation．This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel．
"Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project．"In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said．"Their projects will last initially for two years．We provide them with a whole host of tools to carry out their projects including funding and intensive training．" She added．
Coral reefs are the planet's most diverse marine ecosystem（生態(tài)系統(tǒng)）, known as the rainforests of the oceans．Despite taking up under 0．2% of the ocean floor, they provide food and shelter for almost a third of all sea life．If we lose the ecosystems, we lose not only the biodiversity （生物多樣性）, but we also lose the capability of people to obtain income and food from coral reefs．
Climatic instability, which leads to rising sea temperatures, causes corals to bleach．Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour．Bleached corals often die if the stress continues．Among the 10 species chosen to start the Edge project are the pearl bubble coral, a food source for the hawksbill（玳瑁）turtle, and the Mushroom coral, which supports at least 15 brightly colored fish．
【小題1】What does the first paragraph mean in the passage ?

A．Conservationists planned to preserve and protect some extinct corals years ago．
B．Conservationists have banned plans to protect endangered corals for years．
C．Conservationists are going to protect corals that are dying out in several ten years．
D．Conservationists have made plans to protect corals from being extinct in ten years．
【小題2】What will probably happen to coral species with the increasing threats?
A．Decrease． B．Losing functions
C．Disappearance． D．Existence
【小題3】Which of the following statements about the Edge Plan is TRUE?
A．The Edge Coral Reefs project was carried out by American scientists．
B．The plan concentrates on the channels to protect the endangered species．
C．The Conservationists have carried out the Edge plan for many years to protect the corals．
D．Ten coral species chosen by the project are at the greatest risk of becoming extinct．
【小題4】Which of the following will be the consequence of coral extinction in the passage?
A．We will keep the balance of the marine ecosystems．
B．About one third of the marine species can't survive．
C．Man can benefit more from corals．
D．We will lose the rainforests on our earth．
【小題5】What is the best title of the passage?
A．Climatic Instability and Coral Extinction
B．Reasons for Coral Functional Extinction．
C．A Plan to Save Coral from Extinction
D．A Research about Endangered Coral Reefs．

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino （厄爾尼諾）. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韋）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication（出版物）Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
【小題1】El Nino is known as ___.

A．the changing of the weather in southern Africa
B．the warming of waters in the Pacific Ocean
C．the weather which brings drought（旱災(zāi)）to Africa
D．the weather phenomenon（現(xiàn)象）that brings heavy rains to Africa
【小題2】Scientists study El Nino in order that ___.
A．they can provide a kind of early warning to the place that will suffer from drought
B．they can tell why Zimbabwe has little or no rain
C．they can do some research work in this field.
D．they can put all this information into their computers.
【小題3】Which of the following is TRUE according to the passage?
A．Scientists come to understand how El Nino appears.
B．Three scientists from the USA work on this subject.
C．Southern Africa suffered a serious drought and many people died from hunger.
D．El Nino has something to do with Zimbabwe’s poor crops.
【小題4】Which of the following is NOT true according to the article?
A．The computer is used in this research work.
B．Scientists know when an El Nino appears by means of the computer program.
C．The scientists published their results of the research work.
D．Nature is the name of the article written recently by the scientists.
【小題5】What’s the best title for this passage?
A．Appearance of El Nino is Predictable（可預(yù)測(cè)的）
B．Drought in Zimbabwe
C．Early Warning System
D．Weather in Africa

Every time you go to the supermarket, you come away with your purchases in plastic bags. But wouldn’t it be kinder to the environment if you asked for paper bags instead?
The answer is not the easy as it might seem. Environmentalists say there are drawbacks to using both plastic bags and paper bags.
According to the American Plastics Council 80 percent of groceries in the US are packed in plastic bags.
“The numbers are becoming huge,” said Vincent Cobb, a businessman from Chicago who set up “reusable bags. com” on the Internet. He notes that consumers use between 500 billion and 1 trillion plastic bags per year worldwide.
Some experts believe that all these bags harm the environment. Plastic takes hundreds of years to break down and, as it does so, poisonous materials are released into the water and soil.
Further damage is caused if plastic bags enter the sea. For example, endangered sea turtles cannot tell the bags from jellyfish(水母), their main source of food, and often choke on them.
Floating plastic bags have been spotted as far north as the Arctic Ocean and as far south as the southern end of South America. One expert predicts that, within ten years, plastic bags will wash up in Antarctica!
However, this kind of bag does have its advantages.
“Plastic grocery bags are some of the most reused things around the house,” explained Laurie Kusek of the American Plastics Council.
According to the Film and Bag Federation, a trade group in the US plastics industry, paper bags use more energy and create more waste than plastic bags. Plastic bags require 40 per cent less energy to produce and cause 70 per cent less air pollution, the group explained. They also release as much as 94 percent less waste into the water than paper ones.
But paper bags do break down more quickly than plastic bags. They don’t endanger wildlife, either.
So what should we do? One possible solution would be to use biodegradable(能被生物分解的)plastic bags. But until biodegradable technology improves, it might be easier to pack things you buy in reusable cloth bags.
【小題1】The best title of the passage is _____.

A．Paper Causes Less Pollution 
B．Plastic Causes Less Pollution 
C．Paper and Plastics Cause Pollution 
D．Paper Bags Break Down More Quickly 
【小題2】The underlined word “drawbacks” might mean “_____”.
A．Advantages B．disadvantages C．a(chǎn)ir pollution D．waste 
【小題3】According to the passage, which of the following in NOT true?
A．Plastic takes longer to break down than paper. 
B．Sea turtles usually mistake the plastic bags for jellyfish. 
C．Paper bags require less energy than plastic bags. 
D．You’d better pack things in reusable cloth bags. 
【小題4】Which of the following shows that paper bags are better than plastic ones?
A．Paper bags take less time to rot. 
B．Paper bags cause less air pollution. 
C．Paper bags are more reusable. 
D．Paper bags cause less water pollution.

It’s 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his e-mail and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write ... Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John’s house, and he is a telecommuter —  he works at home, communicating with the workplace through the Internet.
Like John, millions of people — and their employers — are finding that telecommuting is a great way to work. Telecommuters can follow their own timetables. They work in the comfort of homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems.
Jobs that are suited to telecommuting include writing, design work, computer programming and accounting. If a job is related to working with information, a telecommuter can probably do it.
【小題1】From the passage we can learn that John does his job           .

A．by telephon B．through the Internet

As most university students are packing their bags，boarding trains or flying home for the Spring Festival，some will stay behind to spend the holiday on campus．
Zhou Yunyun，22，a senior finance major at Jilin University，has decided that instead of traveling to Hainan province，he will kill the time by playing computer games with his online friends．
“I'm used to chatting and playing with them every day．It’s just fun to make friends this way，”he said．“When I returned home in past years，my relatives always asked me a lot of questions about my plans after graduation．They had high expectations of me，which made me feel stressed，” said Zhou．
The campus，usually lively，will probably turn into a death town，with most restaurants，shops and student centers closed during the break．But there are also a few advantages，according to Jia Debao，2 1，a junior majoring in administration at China Agricultural University．“I might feel a bit lonely，but at least I can stay away from my parents’ complaining and enjoy the peaceful and quiet stay，” he said．“More importantly，I can enjoy the high speed of the Internet，I can always find empty seats in classrooms，and I don’t have to wait to use the bathroorm” But education experts recommend students who stay on campus to come up with more interactive plans．That’s because communication on the Internet can’t replace real life interpersonal relationships．
Society has promoted a kind of“couch potato" or close-in culture among some young people, according to Shi Tongyu, a researcher at the Chinese Academy of Social Sciences. He warned that this kind of lifestyle can damage students’ mental and physical development.
“When you constantly stare at a computer screen and type on your keyboard，you gradually lose the ability to socialize and survive normally，"said Shi．“A human’s most important task is to survive，which cannot be completed by staying at home all the time． Instead，it must be achieved through real life experience and communication．”

Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new mobile at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a website and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety：“60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”
【小題1】Why does the author mention Kelly’s experience in the first paragraph? 

A．To introduce the topic for discussion. 
B．To inform us that mobile phones are useful. 
C．To warn us that we should be careful. 
D．To tell us we should get phones ready for a trip. 
【小題2】The underlined word “nomophobia” in Paragraph 2 means “     ” .
A．habits of using mobile phones 
B．fear of losing mobile phones 
C．eagerness for new mobile phones 
D．independence of mobile phones 
【小題3】 Which of the following is a way to treat nomophobia?
A．Avoiding using a phone for some time 
B．Learning more about modern technology 
C．Protecting one’s phone against any damage 
D．Not using a mobile phone in one’s daily work 
【小題4】What is the passage mainly about?
A．Attitude toward mobile phones 
B．New mobile phone technology  
C．Disadvantages of mobile phones 
D．Solutions to nomophobia
