Sometime early in the next century, human beings will move to Mars. They will live there for about a year, and then will be replaced with another group of pioneers. Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means altering a planet’s surface so that Earth’s life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth’s plants and animals in the order in which they developed on Earth. But it will take at least 300 years.
Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places.
While the possibility of such a project is small, it is not impossible .Even if earth –bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to terraform Mars.

Let us begin by saying what does not cause our dreams. Our dreams do not come from “another world ”. They are not messages from outside source. They are not a look into the future , either .
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind .If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has effect on you while you are sleeping (feeling of cold, a noise, a discomfort, etc.) and it may also use your past experiences and the wishes and the interests you have now.This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom.
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment.A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton.He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands!
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean.Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem.They believe that dreams are mostly expressions of wishes that do not come true.In other words, dreams are a way of having your wishes carried out.
小題1:From the passage we know that our dreams ___________.
A.a(chǎn)re imagination of our daily life
B.a(chǎn)re man’s curious look into the future
C.have nothing to do with our feelings
D.a(chǎn)re to some degree connected with our feelings
小題2:Older children often dream of examinations probably because ___________.
A.they are interested in exams
B.they are often worried about their studies
C.they hope for a better life
D.they show much interest in their studies
小題3:According to the writer , the explanation of dreams that some scientists made ___________.
A.is considered interesting , but unreasonable
B.gives a good answer to the question why we dream
C.has some value , though not fully convincing
D.has been proved by the findings of their studies
小題4:What is the best title for this passage ?
A.Why People Dream ? B.New Findings about Dreams

If you are planning to study in the United States, you need to consider several factors. Everyone has different opinions about where is the best place to live in. Also, the best places to live in are not always home to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute of Technology, for example, is a great school for computer science and technology-related fields of study. However, if you want to study oceanography(海洋學(xué)), your interests may be better served by attending school in a place that is on a coastline or near the ocean.
Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in.
California is a nice state. Northern California specifically has very good weather. Los Angeles in southern California is another story, though. Life in LA is full of excitement and fast, and sometimes dangerous. As for me, I enjoyed the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of history and culture. The weather is not as perfect as Northern California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there.
Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won’t like the Midwest or even the Northeast. Open space, nature and peace? Then you probably should stay away from America’s large cities. Are you interested in government? Then Washington D. C. is the only place for you. Whatever you decide, put some thought into it. The place you live in could be the difference between a great study-abroad experience and a state of great suffering on earth.
小題1:What, according to the author, should be considered first if you want to study in the USA?
A.The climateB.The scenery
C.The study conditionD.The living condition
小題2:What is California like?
A.California is the best place to live in.
B.California is the worst place to live in.
C.California is a state with the largest city.
D.California is a state with different climates.
小題3: If you study in Middle America, you can probably _______.
A.find the best universities
B.feel the real character of the nation
C.meet the most famous professors there
D.face more difficulties
小題4: What can we conclude from the text?
A.All American famous universities lie in nice places.
B. Los Angeles is the most dangerous city in the USA.
C. Washington D.C. is the political centre of the USA.
D. It is always raining in the Midwest of the USA.

A successful scientist is generally a good observer.  He makes full 36  of the facts he observes.  He doesn’t accept ideas which are not  37   on obvious facts,  and therefore refuses to accept authority as the only   38   for truth.  He always  39    ideas carefully and makes experiments to prove them.
The rise of    40    science may perhaps be considered to    41   as far back as the    42    of Roger Bacon,  the wonderful philosopher of Oxford,  who live    43    the years 1214 and 1292.  He was probably the first in the Middle    44    to suggest that we must learn science    45    observing and experimenting on the things around us,  and he himself    46   many important discoveries.
Galileo,  however,  who lived more than 300 years later (1564-1642),  was the greatest of several great men,     47    in Italy,  France,  Germany,  or England,  began by    48    to show how many important    49    could be discovered by observation.  Before Galileo,  learned men believed that large bodies fell more    50    towards the earth than small ones,     51    Aristotle said so.  But Galileo,  going to the    52     of the leaning Tower of Pisa,  let fall two  53    stones and proved Aristotle was wrong.  It was Galileo’s    54    of going direct to Nature,  and proving our    55    and theories by experiment,  that has led to all the discoveries of modern science.

China is now sending more college students to study in the United States than any other country.  A new report shows a 23 percent increase in the number of Chinese students coming to the U.S.
The latest edition of the annual Institute of International Education(IIE)and another US institute found a 5 percent rise in the number of international university students in the US compared to one year ago. There are now over 157, 000 Chinese students at U.S. colleges and universities.
Aisa accounted for four of the top five countries and regions to take advantage of the US higher education system. “Increased numbers of students from China, particularly at the undergraduate level, largely accounts for the growth this past year,” the report stated. “They really enroll in a full range of US higher education,” said Peggy Blumenthal, senior counselor to the president of IIE, the group that made the report. “20 years ago, students from China only knew of a handful of US insitiutions, but now, they are enrolling in our community colleges, in our small liberal arts institutions, in the research universities. Really spread across the country,” she said.
Chinese mainland was in the number one spot, while India was the number two country of origin. South Korea was third and Canada was number four. China’s Taiwan held the number five spot. Saudi Arabia was in sixth with a 44-percent increase, while Japan was seventh, down 14 percent.
Blumenthal attributes the increase in the number of Chinese students heading to US colleges to limited university places in China, as well as a feeling from students and their parents than they want a “unique” educational experience. China’s family planning policy, says Blumenthal, has also meant that families can concentrated resources on a single child.
The University of California at Los Angeles has one of the largest Asian student populations of any college in the United States.
小題1:Which ranked the third place sharing US higher education?
A.Saudi ArabiaB.South KoreaC.CanadaD.India
小題2:Why is the number of Chinese students going to the US increasing?
A.The US colleges are better than those in China.
B.Each family in China has only one child.
C.China lacks enough educational resources.
D.Chinese students can enter varieties of US colleges.
小題3:Which of the following is right according to Peggy Blumenthal?
A.The number of Chinese students going to the US has increased by 23%.
B.The University of California has contributed to Asian education greatly.
C.Chinese student populations in the US mainly consist of undergraduates.
D.Chinese students know more about US higher education than before.
小題4:The best title for the passage can be           .
A.Chinese College Students Rush to US Schools
B.The Large Number of Chinese Students in the US
C.Chinese Students Make Up Largely Foreign Students in the US
D.Asian Middle School Students in the US Universities

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (肌腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版稅). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because __________.
A.people did not know how to put out the fire
B.Elias Howe thought Thimonnier had stolen his invention
C.the sewing machines couldn’t work finally
D.workers who feared the loss of their jobs to a machine set fire
小題2:Why did the court force Isaac Singer to pay Elias Howe a lifetime of royalties?
A.Because the judge was against Singer for his unfriendly attitude.
B.Because Howe had already patented the lockstitch used by Singer.
C.Because Singer had borrowed money from Howe and never repaid it.
D.Because Singer and Howe had both invented the same machine.
小題3:Which of the following would be the best title for this passage?
A.A Stitch in Time Saves Nine
B.The Case between Howe and Singer
C.Patent Laws on the Sewing Machine
D.The Early History of the Sewing Machine

When next year’s crop of high-school graduates arrive at Oxford University in the fall of 2009, they’ll be joined by a new face; Andrew Hamilton, the 55-year-old provost (教務(wù)長(zhǎng)) of Yale, who’ll become Oxford’s vice-chancellor—a position equivalent to university president in America.
  Hamilton isn’t the only educator crossing the Atlantic. Schools in France, Egypt, Singapore, etc, have also recently made top-level hires from abroad. Higher education has become a big and competitive business nowadays, and like so many businesses, it’s gone global. Yet the talent flow isn’t universal. High-level personnel tend to head in only one direction: outward from America.
  The chief reason is that American schools don’t tend to seriously consider looking abroad. For example, when the board of the University of Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university’s budget. “We didn’t do any global consideration,” says Patricia Hayes, the board’s chair. The board ultimately picked Bruce Benson, a 69-year-old Colorado businessman and political activist (活動(dòng)家) who is likely to do well in the main task of modern university presidents: fund-raising. Fund-raising is a distinctively American thing, since U.S. schools rely heavily on donations. The fund-raising ability is largely a product of experience and necessity.
  Many European universities, meanwhile, are still mostly dependent on government funding. But government support has failed to keep pace with rising student number. The decline in government support has made funding-raising an increasing necessary ability among administrators and has hiring committees hungry for Americans.
  In the past few years, prominent schools around the world have joined the trend. In 2003, when Cambridge University appointed Alison Richard, another former Yale provost, as its vice-chancellor, the university publicly stressed that in her previous job she had overseen “a major strengthening of Yale’s financial position.”
  Of course, fund-raising isn’t the only skill outsiders offer. The globalization of education means more universities will be seeking heads with international experience of some kind of promote international programs and attract a global student body. Foreigners can offer a fresh perspective on established practices.
小題1:What is the current trend in higher education discussed in the passage?
A.Institutions worldwide are hiring administrators from the U.S.
B.A lot of political activists are being recruited as administrators.
C.American universities are enrolling more international students.
D.University presidents are paying more attention to funding-raising.
小題2:What is the chief consideration of American universities when hiring top-level administrators?
A.The political correctness.
B.Their ability to raise funds.
C.Their fame in academic circles.
D.Their administrative experience.
小題3:What do we learn about European universities from the passage?
A.The tuitions they charge have been rising considerably.
B.Their operation is under strict government supervision.
C.They are strengthening their position by globalization.
D.Most of their revenues come from the government.
小題4:Cambridge University appointed Alison Richard as its vice-chancellor chiefly because _____.
A.she was known to be good at raising money
B.she could help strengthen its ties with Yale
C.she knew how to attract students overseas
D.she had boosted Yale’s academic status
小題5:In what way do top-level administrators from abroad contribute to university development?
A.They can enhance the university’s image.
B.They will bring with them more international faculty.
C.They will view a lot of things from a new perspective.
D.They can set up new academic disciplines.

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.
There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.
Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.
These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.
We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.
The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.
