The year is 2094,It has been announced that a comet is heading towards the Earth.Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion.About half of the piece is destoryed but the remaining part hits the South Atlantic at 200times the speed of sound.The sea boils and a huge gole is made in the sea bed.Huge waves are created and spread outwards form the hole.The eall of water,a kilometer high,rushes towards southern Africa at 800 kilometers an hour.Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America.the second piece of the comet lands in Argentina.Earthquakes and volcanoes are set off in the Andes Moutains.The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles,San Francisco and Tokyo are completely destroyed by earthquakes,Millions of people in the southern half of the earth are already dead,but the north won’t eacape for long.Because of the explosions the sun is hidden by clouds of dust,and temperatures around the world fall to almost zero.Crops are ruined.The sun won’t be seen again for many years.Wars break out as countries fight for food.A year later,no more than 10 million remain laive.
Could it really happen?In fact,it has already happened more than once in the history of the Earth.The dinesaurs were on the Earth for over 160 million years,Then 65 million years ago they suddenly disappeared.Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out .Will we meet the same end ?What is mainly described in the passage ?
| A．A historic discovery | B．A research on space |
| C．A scientific adventure | D．An imaginary event |
When the first piece hits the South Atlantic,it causes_______.
| A．an earthquake | B．huge waves |

| B．because people there can not live at the temperature of zero. |
| C．Because wars break out among countries. |
| D．Because the light and heat from the sun can not reach the earth. |

In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat if you pick them up within 5 seconds after dropping them.
But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria（细菌）to make you sick.
Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.
One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.
But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna（一种大红肠）on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.
So, forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. And this time, be careful not to drop it!In which part of a newspaper can you most probably find this passage?
| A．Culture | B．Health | C．Advertisement | D．Technology |
After dropping a piece of toast, a person who follows the “5-second rule” will .
| A．throw away dirty toast immediately and go away |
| B．pick up the toast as quickly as possible and eat it |
| C．eat the toast within 5 seconds and feel pleased |
D．get another piece of clean toast quickly and eat it |
The scientists in South Carolina did the experiment to __________ .
| A．see how quickly bacteria can pollute food |
| B．show that the 5-second rule is correct |
| C．see how harmful bacteria are to people’s health |
| D．show that bacteria grow at different speeds on different foods |
“Life is speeding up. Everyone is getting unwell.”
This may sound like something someone would say today. But in fact, an unknown citizen who lived in Rome in AD 52 wrote it.
We all love new inventions. They are exciting, amazing and can even change our lives.
But have all these developments really improve the quality of our lives?
Picture this: You’re rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the television is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to get it done. How calm and happy do you feel?
Inventions have speeded up our lives so much that they often leave us feeling stressed and tired. Why do you think people who live far away from noisy cities, who have no telephones, no cars, not even any electricity often seem to be happier? Perhaps because they lead a simpler life.
One family in the UK went “back in time” to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons Benjamin, 10, and Tomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave, computer or mobile phones.
The grandmother, Lyn, said, “It was hard physically, but not mentally.” She believed life was less materialistic. “The more things you have, the more difficult life becomes,” She said. The boys said they found less to fight over, such as their computer. Benjamin also noticed that his grandmother had changed from being a “trendy（时髦的）, beer-drinking granny, to one who cooked things.”
Here are some simple ways to beat the stress often caused by our inventions!
Don’t be available all the time. Turn off your mobile phone at certain times of the day. Don’t check your e-mail every day.
Don’t reply to somebody as soon as they leave a text message just because you can. It may be fun at first, but it soon gets annoying.
Don’t worry too much about life—laugh more.The passage is mainly about __.
| A．problem with technology |
| B．improvements of our life with technology |
| C．the important roles technology plays in our everyday life |
| D．major changes which will be likely to happen to technology |
The writer quoted（引用）what a citizen in ancient Rome said at the beginning of the story in order to __.
| A．share a truth about life |
| B．tell us what life was like long time ago |
| C．make us wonder what causes such a thing to happen |
| D．point out that you experience some big problems and they may be the same |
Choosing a nice mountain bike for you is easier than learning how to ride it. Keep these tips in mind：
Decide how you are going to use your new mountain bike.
Are you a new rider who simply wants to travel outdoors on the weekend，weather permitting？Do you intend to test yourself on the rough roads，every day，rain or shine？Or are you going to use your new mountain bike to ride to and from school or work？Be honest about your intentions，and you’re more than half way toward choosing the right mountain bike for you.
Visit your local bike shops.
Any good bike shop will stock a wide range of quality mountain bikes in all price points and sizes. Your local bike shops will carry more than one brand of bicycle. Not only will they sell you a mountain bike that suits your needs，but they will service what they sell. Visit at least a few shops. You’ll get one that satisfies you right away.
Don’t be bashful.
Tell your salesperson how you intend to use your new mountain bike，and how much you are willing to spend. Your salesperson will show you a selection of models and brands accordingly. He or she will also help you determine the right size for you. You may ask more without any sense of shyness.
Take a test ride.
All good bike shops let customers take test rides. There’s a good reason for this beyond “trybeforeyoubuy” salesmanship. Since you already know your price range and find the right size，you now have to find out which brand you ride best. They want you to be happy with your purchase. After only a few test rides from more than one bike shop，the right mountain bike will choose you.

Compared to people with bad attitudes，people who are cheerful and relaxed are less likely to suffer from colds，according to a new study.“It’s possible that being upbeat helps the body fight illnesses，” says Sheldon Cohen，the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.
In a previous（先前的） study，Cohen and his colleagues put coldcausing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles，coughs，and other 
cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors，even when medical tests detected those symptoms.
Those findings were interesting，but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead，it was still possible that a person’s underlying personality is what matters. Evidence suggests，for instance，that certain people are naturally more likely to be outgoing and optimistic，with high selfesteem and a sense of control over life. This would mean that who we are，not how we feel，ultimately decides our chances of catching colds.
To figure out which mattered more (personality or emotions)，the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period，people got nose drops that contained either cold or flu viruses. Then，each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms，however，differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus，for example,2
8 percent developed coughs and stuffy noses. On the other hand，those symptoms struck 41 percent of people who had been less upbeat.

After graduating from college she tried to get a job in her major field—physics. She soon found it was almost impossible for a woman.
Agnes spent a full year looking for a job. Finally she gave up in anger. She began writing letters of anger to various newspapers. An editor in New York liked her ideas very much.
