In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet（彗星）. When the fragment（碎片）landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our plant, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
On 17 July, a fragment four kilometers wide enters the Earth’s atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
Millions of people are already dead in the southern part of the Earth, but the north won’t escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs（恐龍）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 space fragment. The dinosaurs couldn’t survive in the cold climate that followed and they became extinct. Will we meet the same end?
【小題1】Which of the following is NOT TRUE according to the author’s description of the disaster in 2094?
| A．The whole world becomes extremely cold. |
| B．All the coastal cities in African are destroyed. |
| C．The whole mankind becomes extinct. |
| D．The visit of the comet results in wars. |
| A．Because they could only live in the warm climate. |
| B．Because they once ruled the Earth. |
| C．Because their extinction shows future disasters. |

What will people die of 100 years from now？ If you think that is not a simple question， you have not been paying attention to the revolution that is taking place in biotechnology(生物技術(shù)). With the help of new medicine， the human body will last a very long time. Death will come mainly from accidents， murder and war. Today's leading killers， such as heart disease， cancer， and aging itself， will become distant memories.
In discussion of technological changes， the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live？ Human brains were known to decide the final death. Cells are the basic units of all living things， and until recently， scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells， such as those of brain cells， would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100， medicine will have advanced to the point at which every 10 years or so， people will be able to take medicine to repair their organs. The medicine， made up of the basic building materials of life， will build new brain cells， heart cells，and so on－in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence， but many technical problems still must be cleared up on the way to this wonderful future.
【小題1】According to the passage， human death is now mainly caused by____
| A．diseases and aging | B．a(chǎn)ccidents and war |
| C．a(chǎn)ccidents and aging | D．heart disease and war |
| A．heart disease will be far away from us |
| B．human brains can decide the final death |
| C．the basic materials of cells will last forever |
| D．human organs can be repaired by new medicine |
| A．human life will not last more than 120 years in the future |
| B．humans have to take medicine to build new skin cells now |
| C．much needs to be done before humans can have a longer life |
| D．we have already solved the technical problems in building new cells |

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中風(fēng)）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
【小題1】The text mainly discusses the relationship between ______ .
| A．heart problems and air quality | B．heart problems and exercising |
| C．heart problems and smoking | D．heart problems and fatty food |
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
| A．Eating fatty food has immediate effects on your heart. |
| B．The EPA conducted many studies on air quality. |
| C．Moderate air quality is more harmful than smoking. |
| D．Stricter regulations on pollutants should be made. |
| A．inform | B．persuade | C．describe | D．entertain |

Huge waves are created and spread outwards from the hole. The wall 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 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 Mountains. 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 escape for long. Because of the explosions, the sun is hidden by clouds of dust, 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 people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years.

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The findings came from a survey of more than three hundred forty thousand adults in the United States. The Gallup Organization questioned them by telephone in two thousand eight. At that time, the people were between the ages of eighteen and eighty-five.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.
The findings showed that stress levels dropped sharply after people reached their fifties.
Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
【小題1】What is the best title of the passage?
| A．The older a person is, the happier he grows. |
| B．The more lighthearted a person is, the happier he is. |
| C．The older a person is, the more clever he grows. |
| D．The older a person is, the more stressed he feels. |
| A．only when people get older, will they feel happier |
| B．older people usually have no worries in their life |
| C．older people are more likely to be thankful in life |
| D．stress levels among the youngest are the highest of all |
| A．When people get older, they can’t remember bad experiences. |
| B．When people get older, they have no young children to care about. |
| C．When people get older, they don’t care about their feelings. |
| D．When people get older, they learn to adjust their feelings. |
| A．Advice to the young people on how to keep happy. |
| B．Why women at all ages are more sad, stressed and worried. |
| C．Advice to the old people on how to live longer. |

People have always been dreaming of going to the moon. As long as the year 1901, H. G. Wells, an English writer, wrote a book vividly describing a trip to the moon. On landing there, the explorers discovered that the moon was full of underground cities. Words failed to express their surprise when they spotted so many “moon people”. The “moon people” felt even more surprised. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel”, a tunnel connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太陽能穹頂) would cover the whole city.
Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “moon people” would second it. Would you?
【小題1】The explorers in H. G. Well’s story were surprised to find that the “moon people” .
| A．knew so much about the earth |
| B．understood their language |
| C．lived in underground cities |
| D．were advanced in technology |
| A．Discovering the moon’s inner space |
| B．Using the earth’s inner space |
| C．Meeting the “moon people” again |
| D．Traveling to outer space |
| A．Offices, shopping areas, power stations. |
| B．Tunnels, car parks, shopping areas. |
| C．Gardens, car parks, power stations. |
| D．Tunnels, gardens, offices. |
| A．H. G. Wells once went to moon himself. |
| B．Underground cities are more comfortable. |
| C．The solar dome is a necessary part of underground cities. |
| D．More underground systems will be in place in 2013. |
| A．Alice Cities — cities of the future |
| B．Space travel with H. G. Wells |
| C．Enjoy living underground |
| D．Building down, not up |

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting (收縮) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions（反應(yīng)）to fear as they were shown pictures of fearful faces. Dr Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see - and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner (掃描儀) to show how the brain influences the way the heart changes a person's feeling of fear.
"We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear," Dr Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder."
【小題1】What is the finding of the study?
| A．One's heart affects how he feels fear. |
| B．Fear is a result of one's relaxed heartbeat. |
| C．Fear has something to do with one's health. |
| D．One’s fast heartbeats are likely to cause fear. |
| A．volunteers' heartbeats when they saw terrible pictures |
| B．the time volunteers saw fearful pictures and their health conditions |
| C．volunteers' reactions to horrible pictures and data from their brain scans |
| D．different pictures shown to volunteers and their heart-brain communication |
| A．Order. | B．System. | C．Machine. | D．Treatment. |
| A．treating anxiety and stress better |
| B．explaining the cycle of fear and anxiety |
| C．finding the key to the heart-brain communication |
| D．understanding different fears in our hearts and heads |

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger ,but we also affect our water supply in less obvious ways .You may wonder how paving(鋪砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater . Groundwater does not come from lakes or rivers .It come from underground . The more roads and parking lots we pave ,the less water can flow into the ground to become groundwater .
Human activity is not responsible for all water shortages(短缺). Driver climates are of course more likely to have droughts(干旱) than areas with more rainfall ,but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference ,too In the United States ,a family of four can use 1.5tons of water a day ! This shows how much we depend on water to live ,but there’s a lot we can do to lower the number .
You can take steps to save water in your home .To start with ,use the same glass for your drinking water all day .Wash it only once a day .Run your dishwasher (洗碗機(jī))only when it is full .Help your parents fix any leaks in your home . You can even help to keep our water supply clean by recycling batteries instead of throwing them away .
【小題1】Which of the following is most likely to lead to less groundwater ?
| A．Using river water . |
| B．Throwing batteries away . |
| C．paving parking lots . |
| D．Throwing rubbish into lakes . |
| A．All water shortages are due to human behavior . |
| B．It takes a lot of effort to meet our water needs . |
| C．There is much we can do to reduce family size . |
| D．The average family in America makes proper use of water . |
| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．prove what drinking glass is best for us |
| D．suggest what we do to save water at home |
| A．Why paving roads reduces our water |
