Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It's wise to be afraid to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn as soon as possible, these four basic strokes; butterfly, backstroke, breaststroke and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming there are certain rules every swimmer should follow:
1. Never swim alone! No matter how good you are in the water, don't risk drowning(溺死) by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble.
2. Don’t go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach. Showing off by doing dangerous tricks is not good.
Swim safely and you will continue to swim and alive.
3. Don’t smoke. Swimming depends on a healthy body; good lungs are part of it.
4. Work at any activity that builds muscles.

The name sounds funny but the idea is no joke: it’s a personal toilet called the pee-pool, Anders Wilhelmson, a Swedish architect, is the inventor of the pee-pool.
He became interested in the idea of sanitation(衛(wèi)生設(shè)施) after taking part in a research project on the social and political development of cities, One of the most common problems he found in developing countries was the lack of toilets, He wanted to do something to help, So working with others, he started the project in 2005, and the next year started a company called Peepoolple.
The toilet is a single—use bag made of environmentally friendly plastics, The inside is treated with urea （尿素）, a chemical commonly used as fertilizer, The hotter the weather, the more quickly the waste turns into what is needed by plants The sanitation process can be as soon as a couple of hours or as long as two to four weeks ,You can just bury it in a pot and grow whatever you like.
The company expects to start selling the bags in August in Kenya and Bangladesh, But it is just beginning production and sales in Nairobi now , Full production could reach about half a million bags a day and people may be able to buy the pee-pool in countries Vietnam, Bangladesh, etc.
The United Nations says more than two and a half billion people around the world do not have good sanitation ,Many have no choice but to use the outdoors, which is not only bad for the environment ,but also harmful to people’s health, Each year, poor sanitation leads to three fifths of those people getting an infectious disease which on average causes one out of 1,000 patients to die.
Jack Smith ,the founder of the World Toilet Organization ,says “This is quite an unacceptable situation given the fact that we are living in the modem world , And strangely, many of them own televisions ,phones but have no toilet.”
【小題1】What was the original purpose of Anders Wilhelmson in starting the company?
| A．To protect the local environment |
| B．To earn a lot of money from the project |
| C．To do research on the social development |
| D．To help solve the problem of lack of toilets in developing countries |
| A．It can be used over again |
| B．Its sanitation process doesn’t last long |
| C．It works better in summer than in winter |
| D．It should be buried in a pot after being used |
| A．Nairobi | B．Vietnam | C．Sweden | D．Bangladesh |
| A．poor sanitation may cause many problems |
| B．many people don’t care for the environment |
| C．many people get ill from using the outdoors |
| D．quite a number of people died from poor sanitation |

How to Tell If Someone Is Happy or Sad on the Phone
Scientists have come up with some researches on what makes different types of people“tick”.
The scientists at the University of Cambridge have developed new mobile phone technology called Emotion Sense that can tell if a caller is happy, angry or sad.
Scientists hope to fit the speech recognition system to standard mobile phones and use it to determine emotions—it will also use a GPS tracking system to log where the call is made.
And they’ve already made some pretty major breakthroughs into really getting under the skin of us humans.
The results from the pilot scheme make interesting scientific reading. Among the key revelations (﹦facts) are that callers feel happier at home and sadder at work.
To break it down, scientifically, it shows 45 percent of all emotions produced at home are “happy”and 54 percent of emotions at work are “sad”.
Meanwhile, people show more “intense”(﹦nervous) emotions in the evening than they do in the morning.
Of course, this could just be because most people feel too tired in the morning to get overly “intense”. Eating breakfast and getting to work on time is usually enough of an achievement.
Anyway, the Emotion Sense technology has been developed by psychologists(心理學(xué)家) and computer scientists who say it uses speech recognition software and phone sensors(傳感器) attached to standard smart phones to judge how callers’ emotions are changed by everyday factors.
The sensors analyze voice samples and these are then divided into five categories: happiness, sadness, fearfulness, anger or neutral-—boredom or passivity(消極) would fit into this last category.
【小題1】How many emotions can the sensors tell?
| A．Two | B．Three | C．Four | D．Five |
| A．Scientists have put something testing people’s emotions under humans’ skin. |
| B．There were some breakthroughs in this technology in getting something from people’s skin. |
| C．In this technology, people’s skin was broken through. |
| D．There were improvements in testing people’s emotions. |
| A．Because morning is the start of a new day. |
| B．because they feel too tired in the morning. |
| C．Because of humans’ physiological structure. |
| D．Because of the fresh air and bright sunlight. |
| A．Speech recognition software. | B．Phone sensors. |
| C．GPS sensors. | D．Translation system. |

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.
Adaptable glasses
Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透鏡）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (發(fā)電機) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.
The Dyson cleaner
In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata fly-board
Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200.
So keep dreaming and inventing. One day you might get it right.
【小題1】What can we learn about Adaptable glasses?
| A．They are very expensive. | B．The inventor is a student. |
| C．The glasses are fragile. | D．They don’t look very nice. |
| A．Adaptable glasses. | B．The wind-up radio. |
| C．The Dyson cleaner. | D．The Zapata fly-board. |
| A．helping people use cleaners more easily |
| B．making Dyson a rich businessman |
| C．keeping the house cleaner than before |
| D．taking the place of human cleaners |

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. |
| A．habits of using mobile phones |
| B．fear of losing mobile phones |
| C．eagerness for new mobile phones |
| D．independence of mobile phones |
| 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 |
| A．Attitude toward mobile phones |
| B．New mobile phone technology |
| C．Disadvantages of mobile phones |

To get a chocolate out of a box requires a lot of unpacking: the box has to be taken out of the paper bag in which it arrived, the cellophane (玻璃紙) wrapper has to be torn off, the lid opened and the paper removed, the chocolate itself then has to be unwrapped from its own piece of paper. But this overuse of wrapping is not limited to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in beautiful wrapping.
The package itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put out by the average London house-hold each week. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up valuable energy and resources and polluting the environment.
Recycling is already happening with milk bottles which are returned to the dairies (牛奶場）, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles.
The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to throw away plastic altogether in the shops, a suggestion unacceptable to many producers who say there is no alternative (替代品) to their handy plastic packs.
It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers rather than producing new ones. Unnecessary packaging, intended to be used just once, and to make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of throwing away packaging as using it wisely. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.
【小題1】The underlined part “this overuse of wrapping is not limited to luxuries” in Paragraph l means ______.
| A．more wrapping is needed for ordinary products |
| B．the wrapping used for luxury products is unnecessary |
| C．more wrapping is used for luxuries than for ordinary products |
| D．too much wrapping is used for both luxury and ordinary products |
| A．It is easy to use it again. |
| B．Packaged things will not go rotten. |
| C．They want to attract more shoppers. |
| D．Shoppers are all interested in beautiful packaging. |
| A．reusing their paper containers |
| B．giving up the use of glass bottles |
| C．increasing the use of plastic bottles |
| D．experimenting with the use of paper bottles |
| A．too much plastic is wasted |
| B．shops should stop using plastic containers |
| C．no alternative can be found to plastic packaging |
| D．plastic packaging should be made more convenient |

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 erase(抹去) 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 erased.
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 changing memories is very dangerous because memories give us our identity (特質(zhì)). They also help us all avoid the mistakes of the past.
"All of us can think of bad events in our lives that were horrible 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.
【小題1】The passage is mainly about ________.
| A．a(chǎn) new medical research |
| B．a(chǎn) new invention of the pill |
| C．a(chǎn)n argument about the research on the pill |
| D．a(chǎn) way of erasing painful memories |
| A．prevent body producing certain chemicals |
| B．cause the brain itself to recover memories |
| C．help people remember the memories |
| D．wipe out the emotional effects of memories |
| A．the pill will prevent people's bad experiences |
| B．people argue about the effects of the pills |
| C．taking the pill will do harm to people's health |
| D．the pill has probably been produced in America |
| A．Some memories can help avoid the mistakes made in the past. |
| B．Changing memories is very dangerous. |
| C．Experiencing bad events makes us different from others. |
| D．The pill will reduce people's sufferings from bad memories. |

We are fortunate to be living in a time when all people have the ability to access any knowledge they desire. This digital society that we live in affords us opportunities that our ancestor only dreamed of having. We should not take this privilege for granted.
In the not so distant past of the 1950s, people who wanted to research an idea, a product, or anything else, had to go to a library where they could look up information in books. Not all people had the same access to the books, and the information they contained. In America, if your skin was black, you could not use the same library that a person with white skin used. If a black skinned person was allowed access to a library, it most likely was stocked with outdated books that white skinned people had discarded.
In the digital society we live in today, the color of your skin does not determine the access you have to information. Technology has brought to us the powerful tools like the Internet where we can find information on almost every subject.
Access to the Internet has allowed us to research the things we are planning to purchase. We are capable of comparing prices on things like insurance, appliances, entertainment, clothing, and all other things. We also now have the ability to purchase items online without ever leaving our homes. We have been freed from the restrictions of store hours, and regional sales. A person in America can purchase a product from a person in Germany, without leaving home.
Because of the digital society we live in our children can learn about anything they are interested in. When they ask you what the dinosaurs ate, you can look it up, and tell them the answer. Because of this people will be smarter in the future, and technology will only improve.
【小題1】By “We should not take this privilege for granted”, the writer means that ______.
| A．we have special right to do anything |
| B．it is wrong to make use of the privilege |
| C．knowledge is important in the digital society |
| D．we should seize the chances the modern society offers |
| A．the Internet brings us a lot of convenience |
| B．people in modern society are mostly wealthy |
| C．we would like to stay at home every day |
| D．we can find anything we like in the world |
| A．people will be much clever than ever |
| B．what the dinosaurs ate seems strange to us |
| C．finding out what the dinosaurs looked like is easy |
| D．we can learn knowledge with the help of technology |

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”
【小題1】What can we learn about Dr. Marcy from the passage?
| A．He is fond of watching Jupiter. |
| B．He is from a scientist family. |
| C．He dislikes working with Paul Butler. |
| D．He is interested in finding life in outer space. |
| A．The planet is not as protective as Jupiter. |
| B．The planet is close to star 55Cancri. |
| C．The planet proves to be a gas planet. |
| D．The planet is as large as Jupiter. |
| A．1995 | B．1985 | C．2002 | D．1981 |
| A．he has found the system similar to the solar system. |
| B．he has discovered an Earth-like planet there. |
| C．he has discovered a rocky planet there. |
| D．he has found signs of life in the system |
| A．they felt discouraged | B．they carried on with it |
| C．they failed in their attempt | D．they made some progress |
