The year is 2094. It has been announced that a comet (彗星)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 of 4 kilometers wide comet enters the Earth’s atmosphere with a massive explosion(爆炸). About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the seabed. Huge waves are created and spread outwards form 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 are drowned(淹死).
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes ash 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. 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?
小題1:What is mainly described in the passage?
A.A historic discovery.
B.An event in imagination.
C.A research on space.
D.A scientific adventure.
小題2:When the first piece hits the South Atlantic, it causes________.
A.a(chǎn)n earthquakeB.hunger
C.a(chǎn)n Earth explosionD.huge waves
小題3:Why can’t the northern half of the earth escape for long?
A.Because the land is covered with water.
B.Because the light and heat form the sun cannot reach the earth.
C.Because people there cannot live at the temperature of zero.
D.Because wars break out among countries.
小題4:By giving the example of dinosaurs, the author tries to prove_________.
A.a(chǎn)nimals could not live in the cold climate
B.what happened 65 million years ago was an invented story
C.the human beings will die out in 2094
D.the Earth could be hit by other objects in space

At the beginning of the 20th century there were more than a million lions worldwide. Today there are less than 30,000 in the wild. The remaining lions are increasingly threatened by habitat loss, hunting and activities to protect farms and cattle.
For generations, Masai tribesmen on the large African plains in southeastern Kenya have hunted lions — to protect their farms and cattle. Today they celebrate the lions’ life.
Noah is an elder in the Masai community. “We have decided as a community of the Masai to lay down our spears, and there will be no more killing of lions in our community.” He is part of a group of Masai visiting the United States promoting (推廣) the Predator Compensation Program.
Conservation International’s Frank Hawkins explains, “The Masai have been living with wildlife for many generations and it has been a conflicting ( 有沖突的) relationship in many ways. They compete with the animals for food as lions eat their cattle. We’re trying to find ways in which the wildlife will become something useful to them.” They had the Predator Compensation Fund founded in 2003. After much discussion, a group of Masai farmers agreed to protect lions. In turn, if lions or other predators kill their cattle, the Masai owner will be paid market value for the dead animals from the fund.
One man said that in the past, when a lion killed cattle, they killed it immediately. And now, after the start of the program, the Masai see the lion population growing. Since 2003, only four lions have been killed here.
小題1:What is the aim of the Predator Compensation Program?
A.To protect people in the wild.B.To protect Masai’s farms.
C.To protect lions only.D.To protect the wildlife.
小題2:According to the passage, why haven’t Masai tribesmen killed many lions since 2003?
A.Because lions don’t eat their cattle any more.
B.Because they will be fined if they kill lions there.
C.Because the fund will pay for dead animals killed by lions
D.Because there are less than 30,000 lions in the wild now.
小題3:What do you think of the Masai ?
A.Wise.B.Mean.C.Generous.D.Stupid.

You can’t hide a natural disaster from children, so how do we prepare them for it? First of all, you should explain to them that acts of nature aren’t necessarily disasters but can become one. These may include floods, hurricanes, tornadoes, winter storms, wild fires, and earthquakes. The way to prepare children for these disasters is to educate them about what each type is and then make it fun by making them “Disaster Masters” or whatever title you can think of.
Making them a Disaster Master won’t be easy. They must know what’s in a disaster emergency kit(工具箱) and why it’s included. You can get your friends involved, too. If your friends have children, they may want to be involved in your emergency preparations. Make it a group project. This is the opportunity for everyone to become familiar with the equipment.
We have to be aware of our conduct and the way we react to stress. The children will be easily influenced by your attitude and demeanor. The calmness, steady manner, and good humor of your spouse (配偶) and you will go a long way toward the easing or the reduction of stress.
Explain to them what they’re likely to encounter or see and describe how people may react. Disasters can come and go very quickly and generally don’t last long. If you must stay away from home, try to get into a routine quickly and encourage them to make new friends. Let them know they can look to their parents and other adults if they become scared or confused. And it’s important to let them know it’s OK to cry during a disaster.
It’s sometimes helpful to let the children draw pictures of what they’ve experienced. Encourage them to write what they learned and what could have been done better. Save the story. Make it part of a documented family history!
小題1:This passage was written mainly to tell us about ______.
A.the importance of mutual help in disaster preparation
B.tips for preparing children for a natural disaster
C.the importance of educating children about natural disasters
D.ways to raise children’s courage in natural disasters
小題2:It is a must that a Disaster Master knows ______.
A.when a natural disaster will come
B.why there are natural disasters
C.how to use a disaster emergency kit
D.how to teach others about emergency preparations
小題3:The underlined word “demeanor” in Paragraph 3 can be replaced by “______”.
A.personalityB.lifestyleC.emotionD.behavior
小題4:When they meet with a natural disaster, children ______.
A.must write down what they see and how they feel
B.should believe that the disaster will never last long
C.can cry if they are frightened
D.should help other children despite the danger

People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a  36  problem. They often accept the opinion or ideas of other people.

There are six  39  in analysing a problem.
  40 , the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must   41  that there is a problem with his bicycle.

Now the person must look for  44  that will make the problem clearer and lead to   45  solutions. For example, suppose Sam  46  that his bike does not work because there is something wrong with the brakes.  47 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.
After  48  the problem, the person should have several suggestions for a possible solution. Take Sam as an example  49, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one  50  seems to be the solution to the problem. Sometimes the  51  idea comes quite  52  because the thinker suddenly sees something in a  53  way.

The office has always been a place to get ahead. Unfortunately, It is also a place where a lot of natural resources start to fall behind. Take a look around next time you’re at work. See how many lights are left on when people leave. See how much paper is being wasted. How much electricity is being used to run computers that are left on. Look at how much water is being wasted in the rest-rooms. And how much solid waste is being thrown out in the rubbish cans. We bet it’s a lot.
Now, here are some simple ways you can produce less waste at work. When you are at the copier, only make the copies you need. Use both sides of the paper when writing something less important. Turn off your lights when you leave. Use a lower watt bulb in your lamp. Drink your coffee or tea out of your mugs instead of single-use cups. Set up a recycling box for cans and one for bottles. And when you’re in the bathroom brushing your teeth or washing your face, don’t let the tap run. Remember, if we use fewer resources today, we’ll save more for tomorrow.
小題1:The main purpose of the passage is to tell people _______.
A.the disadvantages of working in an office

What is a good education? The question is far from being answered. Once more, colleges and universities are changing their programs: they drop "fun courses" and restart some of the traditional subjects neglected (忽視) since the 1960s. Many great schools are again requiring the students to take a number of classes in English, history, literature, the social sciences, philosophy, the natural sciences, and art if they want to get a degree. Meanwhile, the experts are trying to describe the good education of our time. Obviously the purely vocational training once favored is not enough. But neither is the gentleman's education of the nineteenth century. Educational programs must meet the demands of a modern world where men and women have to work and to deal with big problems.
What, then, is a good education of this century? Some educators suggest that it should include foreign languages and the study of foreign cultures; a mastery of English, including the ability to write and speak well, because communications have become all-important in the modern world, and also because "a person who doesn't speak and write clearly doesn't reason clearly either"; some knowledge of the social sciences (sociology, psychology) that deal with human relations and human problems; some basic knowledge of modern science, which would enable future voters to be better informed about current problems like nuclear. Finally, many educators insist that all college graduates should be familiar with computers and modern information system since the educated professionals of tomorrow will have to understand their machines. Is that all? "No, of course not." answer the educators. "We have not mentioned the two great building blocks of education: history and literature!"
小題1:The best title for this passage might be _______.
A.EducationB.A Mastery of English
C.A Good EducationD.Something About Study
小題2:The underlined word "drop" in the first paragraph means _______.
A.desertB.dislikeC.declineD.neglect
小題3:The author thinks that the question about what a good education is _______.
A.has been answered fairly well
B.hasn't been put forward yet
C.has been dealt with successfully
D.has not been answered satisfactorily
小題4:Some educational experts believe a mastery of English should include the ability _______.
A.to read fastB.to write and speak well
C.to write clearly and accuratelyD.to listen and speak skillfully

Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing---paper. No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seems to run out of ink at the critical moment. A “paperless classroom” is what more and more schools are trying to achieve .
Students don’t do any handwriting in this class . Instead , they use palm size , or specially—designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer. Having computers also means that students use the Web. They can look up information on any subject they’re studying from maths to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan over one year ago. We could touch every side of the country through different sites from the forest to refugee camps, she said .“Using a book that’s three or four years old is impossible.”And exams can go on line too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book. A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie—Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computers,”she said .But, with all this technology, there is always the risk that the machines will break down. So , in case of a power failure or technical problems, paper textbooks are still widely available for these hi—tech students.
小題1:What does the part of the last sentence in the first paragraph “run out of ink at the critical moment” mean ?
A.Pens may not write well at the critical moment.
B.Pens get lost easily , so you may not find them at the critical moment.
C.Pens may have little or no ink at the critical moment
D.Pens use ink, while pencils don’t.
小題2:The high school teacher, Judy Herrell, used the example of her class to show that ________.
A.the Web could take them everywhere
B.the Web taught them a lot.
C.the Web is a good tool for information.
D.the Web , better than the textbooks ,can give the latest and comprehensive information.
小題3:The paperless classroom will benefit _________ the most.
A.studentsB.teachersC.treesD.computers
小題4:What does the phrase in the last paragraph “break down ”mean ?
A.Break into piecesB.Stop workingC.Fall downD.Lose control

One day, Mr. Arnold was teaching a lesson, and things were going as normally as ever. He was explaining the story of mankind to his pupils. He told them that, in the beginning, men were nomads; they never stayed in the same place for very long. Instead, they would travel about, here and there, in search of food, wherever it was to be found. And when the food ran out, they would move off somewhere else.
He taught them about the invention of farming and keeping animals. This was an important discovery, because by learning to cultivate(耕作)the land, and care for animals, mankind would always have food steadily available. It also meant that people could remain living in one place, and this made it easier to set about tasks that would take a long while to complete, like building towns, cities, and all that were in them. All the children were listening attracted by this story, until Lucy jumped up:
“And if that was so important and improved everything so much, why are we nomads all over again, Mr. Arnold?”
Mr. Arnold didn’t know what to say. Lucy was a very intelligent girl. He knew that she lived with her parents in a house, so she must know that her family were not nomads; so what did she mean?
“We have all become nomads again,” continued Lucy, “The other day, outside the city, they were cutting the forest down. A while ago a fisherman told me how they fish. It’s the same with everyone: when there’s no more forest left the foresters go elsewhere, and when the fish run out the fishermen move on. That’s what the nomads did, isn’t it ?
The teacher nodded, thoughtfully. Really, Lucy was right Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs, we kept developing it until the land was bare. And then off we would go to the next place! The class spent the rest of the afternoon talking about what they could do to show how to be more civilized.
The next day everyone attended class wearing a green T-shirt, with a message that said “I am not a nomad!
And , from then on, they set about showing that indeed they were not. Every time they knew they needed something, they made sure that they would get it using care and control. If they needed wood or paper, they would make sure that they got the recycled kind. They ordered their fish from fish farms, making sure that the fish they received were not too young and too small. They only used animals that were well cared for, and brought up on farms.
And so, from their little town, those children managed to give up being nomads again, just as prehistoric men had done, so many thousands of years ago.
小題1:From Paragraph 2, we can know that______ .
A.people got tired of living in the same place
B.people gradually got used to living in cities
C.people tended to settle down after learning farming
D.people spent a long time in learning to keep animals
小題2:In the teacher’s opinion, Lucy’s argument was______
A.shockingB.ridiculousC.puzzlingD.reasonable
小題3:Which of the following agrees with the message “I am not a nomad” (Paragraph 7)?
A.People eat young fish for its delicious taste.
B.Foresters leave the place where wood is not available.
C.Fishermen move elsewhere when there is no fish left.
D.People use recycled materials as much as possible.
小題4:The writer tries to make us believe that ______.
A.mankind has been progressing mainly through traveling about
B.it’s unwise for mankind to use the land in an uncontrolled way
C.it’s quite good for students to learn more about the history of mankind
D.in the beginning men were nomads.

If you’re like most students, you may find it challenging to learn a foreign language. However, there are a few tips you can use in order to earn a top grade —— as well as actually use the skills you’ve learned.
One of the most important and basic lessons in dealing with a foreign language is to learn and understand each concept and lesson before moving on to the next one. If you don’t understand one concept but move on to the next chapter anyway, you’re less likely to understand the new material.
Learning a new language is not only an academic tool, but can help you in your everyday life as well. Being good at another language can help you communicate with other people, and help you when traveling to foreign countries, and even make your resume look better.
And it is important to learn correct pronunciation as soon as possible for poor pronunciation can be hard to break. Native speakers of the language as well as others fluent in the language you are learning will appreciate your efforts to learn correct pronunciation.
Gather outside materials such as books, study guides, books on tape, and travel books to aid you in learning the language. Your textbooks can’t possibly teach you everything you need to know, so seeking outside sources is generally a good rule of thumb to keep in mind.
A significant motivator in learning a foreign language is traveling to the country where the language is spoken. That way, you can see firsthand how the language is used, learn the culture, and meet native speakers of the language. Native speakers appreciate sincere attempts of others who take the time to learn their language.
Seek out native speakers of your new language in your school or neighborhood. They can help you with many skills, including pronunciation, and they can provide immediate feedback on your progress.
小題1:This passage is written to        .
A.explain why learning a foreign language is challenging
B.tell us the importance of learning foreign languages
C.tell us some ways of earning a top grade
D.give us some tips on learning foreign languages
小題2:Which of the following can best summarize the main idea of Paragraph 3?
A.Think beyond academics.
B.Learn each concept.
C.Plan a trip to use your skills.
D.Consider a language as a tool.
小題3:We can learn from the passage that           .
A.textbooks are not good for us when learning a foreign language
B.learning pronunciation well from the very beginning is very important
C.poor pronunciation can be easy to break with the help of native speakers
D.seeking too many outside sources will be more harmful than beneficial
小題4:What is suggested doing in the last paragraph?
A.Going on a trip abroad.
B.Practicing with native speakers.
C.Asking for feedback from our teachers.
D.Finding a motivator in learning language.
小題5:In which part of a website would this text probably appear?
