Pierre is a 25-year-old penguin at the California Academy of Sciences. Due to his old age, he was going bald, which made him feel too cold to swim in the pool. Therefore, biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool.

Unlike marine mammals, which have a layer of blubber to keep them warm, penguins depend on their waterproof feathers. Without them, Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water.
"He was cold; he would shake," said Pam Schaller, a senior biologist. Schaller first tried a heat lamp to keep Pierre warm. Then she got another idea: if wetsuits keep humans warm in the cold Pacific, why not make one for Pierre?
Schaller designed the suit, which covered Pierre’s body and had small openings for his flippers.
"I would walk behind him and look at where there were any gaps, and cut and refit and cut and refit until it looked like it was extremely suitable," she said.
One concern was that the other penguins would reject Pierre in his new suit, but in fact, they accepted his new look. He swam freely and got along with others well, although he was the only penguin with a black stomach.
Schaller couldn’t say for sure whether the wetsuit allowed Pierre to recover his fine feathers, but "certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable".
Pierre will take off his suit after his new feathers grow back.
小題1: Pierre felt too cold to swim in the pool because of _____.
A．not having a layer of blubberB．having few feathers due to old age
C．having no wetsuitD．others penguins rejecting him
小題2:The idea of making a wetsuit for Pierre came from _____.
A．total inventionB．the use of wetsuit on humans
C．the use of heat lampD．waterproof feathers
小題3: Schaller followed Pierre in order to see _____.
A．whether other penguins would reject him
B．if anywhere of wetsuit needed to be cut and refit
C．if the wetsuit kept warm
D．whether the wetsuit would keep the feathers from recovering
小題4:What does the underlined word in the second paragraph mean?
A．feeling scaredB．staying aloneC．shaking with coldD．keeping warm
小題5:The best title of the passage is _____.
A．Wetsuit for An Old PenguinB．Old Penguin Getting Bald
C．Unwilling to SwimD．Strange Look of Pierre

小題1:B

  Art is for everyone. Parents can help kids appreciate art by making it available for them. Unfortunately, many adults do not enjoy art simply because they do not understand the stories or context (背景). Actually, children can appreciate art as well as any adult. Here are some simple ways to encourage children to appreciate art.
Find art that will allow children to easily make a connection with their lives. Choose the material according to their ages. Pictures and sculptures of children, for example, or dogs and cats are easily understood, and it is easy to start a conversation about how the themes in the art are connected with familiar people and animals in kids’ lives. Music and dance are very important to children and should also be used.
Explore the stories behind famous, and not so famous, art. Encourage children to make up their own stories about paintings and then research the real story behind the paintings.
Create art with children. Teach them that art is not something that they must only observe but something that they can create. Discuss art with children. Encourage them to express their views on art. Let them know that it is okay to dislike something, and listen to their preferences when planning events.
Visit museums and performances. Explore the artwork in local museums that will interest them. Most cities have children’s theaters and music groups, and often free performances are offered. Many art museums have special tours for children.
Through a variety of artistic experiences, kids will learn how to appreciate art and will enjoy it.
64. When choosing art for children, parents should________.      
A. take their children’s ages and experiences into consideration
B. pay close attention to their children’s ability to understand
C. ask professional artists for some useful advice
D. try to find some art beyond their imagination

How Room Designs Affect Our Work and Feelings
Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical（經(jīng)驗(yàn)的，實(shí)證的） basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.
Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.
In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.
Using nature to improve focus of attention ought to pay off  academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.
Recent study on room lighting design suggests than dim（暗淡的） light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.
So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw（吸管）," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."
小題1:What does Joan Meyers-Levy focus on in her research?
A．Light.B．Ceilings.C．Windows.D．Furniture.
小題2:The passage tells us that ______.
A．the shape of furniture may affect people's feelings
B．lower ceilings may help improve students' creativity
C．children in a dim classroom may improve their grades
D．students in rooms with unblocked views may feel relaxed
小題3:The underlined sentence in the last paragraph probably means that ______.
A．the problem is not approached step by step
B．the researches so far have faults in themselves
C．the problem is too difficult for researchers to detect
D．research in this area is not enough to make generalized patterns
小題4:Which of the following shows the organization of the passage?
CP: Central Point    P: Point   SP: Sub-point（次要點(diǎn)）   C: Conclusion

Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since they, the plants, are the only form of life that is able to get and store energy.
　　The first plants to exist out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（進(jìn)化）took place quickly. By the end of 100 million years, plants had developed their roots（根）,and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.
　小題1:The main idea of the first paragraph is ________.
A．life on land probably began 430 years ago
B．the first animal on land came from oceans
C．there wouldn't be animals without plants
D．plants are the only form of life that is able to get and store energy
　小題2:Which of the following statements is true according to the passage?
A．Algae has existed for more than 430 million years.
B．It is impossible that algae might be the earliest plant on land.
C．Plants get food from animals in the oceans.
D．Evolution began after animals appeared on land.
　小題3:Plants with roots appeared about ________ million years ago.
A．430B．300C．330D．100
　小題4:According to the passage, ________ appeared earlier than ________.
A．a(chǎn)pples; orangesB．oranges; apples
C．oranges; rosesD．a(chǎn)lgae; wheat

The South Pole is a particular place on the earth.When people stand at the top of it looking around,they will find all directions face to north.No matter how they make their first step in which direction,they will always walk towards the north.That’s to say,only north and south exist there,neither east nor west exists.
At the top of the South Pole,any clock or watch keeps good time because all meridians（子午線） join there.All kinds of local time are completely suitable there.It is even difficult to distinguish（區(qū)別） New Year’s Eve from New Year’s Day.
The explorers and scientists from different countries always fix the time according to their own.Therefore the time by their watches was different when the people with different nationality gathered there.
The Winter Solstice（冬至日） is an important festival at the South Pole.It is always on June 21 or 22.This day is called Midwinter Festival,on which the daytime is the shortest in a year and the night the longest.All people at the South Pole extend greetings to each other and present gifts to each other.They usually give all kinds of celebrations.From that day on,the daytime will get longer day by day.

Every autumn, as families across the United States get ready to send their kids to college, the economics of higher education receive renewed attention. College is expensive and becoming more so in the U. S. The situation raises two questions: Why does it cost so much, and how can students and their families afford it?
Several studies published in the past few weeks reflect on these questions. The findings provide comfort to poor families.
First, it appears that only the minority actually pay the "high price". A study by the US Education Department's National Center for Education Statistics found that 55 percent of college students last year received some forms of help--scholarships, loans(貸款)or jobs.
Other factors are also at work. The government has increased the size of its grants (補(bǔ)助金)to lower-income students. Grants, unlike loans, don't have to he repaid and are awarded only to college students who have not earned a bachelor's or professional degree.
At the same time, most colleges are spending more on undergraduate education than they are collecting in tuition fees. A study, which is part of the Williams College Project on the Economics of Higher Education, reaches the conclusion that on average colleges “subsidize (贊助)” their students. The results of these studies, however, leave unanswered the questions of whether educational costs are higher than they need to be. Some experts argue that much of the college cost results from educational competition for fame, students and facilities.
This puts upward pressure on tuition, hut many colleges feel that good fame will enable them to attract students even if they charge them more.
Therefore, until something important changes in the marketplace, costs seem likely to continue rising. And American families will continue to beat down the doors of the high price "college in the end．
小題1: From the fourth paragraph of the passage we can conclude that _______.
A．American families earn only a little money every year
B．American families pay little attention to education
C．American students often have to stop their studies
D．American colleges have different ways to help poor students
小題2: In the writer's opinion, for students from lower-income families, the best way is ________.
A．to find a good job and make money
B．to borrow money from the banks
C．to ask for grants
D．to borrow money from friends
小題3: It can be inferred that in America _______.
A．famous colleges only accept rich students.
B．famous colleges charge their students more money
C．the government spends little money on education
D．families often break the doors of colleges
小題4: The writer of this passage seems to hold the opinion that _______.
A．college fees rise too fast for poor families.
B．poor people should borrow money from banks
C．poor people don’t need to send their children to college
D．colleges should get more money to improve themselves

Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents—to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence?
The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis, by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction—by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science.
A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation—these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times.
The attempt to discover the explanation of this phenomenon in the antithesis of “facts” and “theories” or “facts” and “ideas”—in the neglect among the ancients of the former, and their too exclusive attention to the latter—proves also to be too narrow, as well as open to the charge of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories.
Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on the other hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact.
小題1:     The title that best expresses the ideas of this passage is
[A]. Philosophy of mathematics.              [B]. The Recent Growth in Science.
[C]. The Verification of Facts.                [C]. Methods of Scientific Inquiry.
小題2:According to the author, one possible reason for the growth of science during the days of the ancient Greeks and in modern times is
[A]. the similarity between the two periods.
[B]. that it was an act of God.
[C]. that both tried to develop the inductive method.
[D]. due to the decline of the deductive method.
小題3:     The difference between “fact” and “theory”
[A]. is that the latter needs confirmation.
[B]. rests on the simplicity of the former.
[C]. is the difference between the modern scientists and the ancient Greeks.
[D]. helps us to understand the deductive method.
小題4:     According to the author, mathematics is
[A]. an inductive science.           [B]. in need of simple verification.
[C]. a deductive science.            [D]. based on fact and theory.
小題5:     The statement “Theories are facts” may be called.
[A]. a metaphor.                  [B]. a paradox.
[C]. an appraisal of the inductive and deductive methods.
[D]. a pun.

Modern man has cleared the forests for farmland and for wood,and has also carelessly burned them. More than that,though,he has also interfered （干涉） with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau （凱亞巴布高原） of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
The Kaibab had a storybook forest of largesized pine,Douglas fir,white fir,blue and Engelmann spruce. In 1882 a visitor noted,"We,who ... have wandered through its forests and parks,have come to regard it as the most enchanting region it has ever been our privilege （特權(quán)） to visit."This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions,timber wolves and bobcats that kept the deer from multiplying too rapidly.
Then,in 1906,President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time,6,250 mountain lions,wolves and bobcats were killed. Before the program,there were about 4,000 deer in the Kaibab,by 1924,there were about 100,000.
The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd （鹿群），but a far greater loss resulted from starvation （饑餓） and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.
小題1:The destruction of the environment of the Kaibab resulted from .
A．turning the forest into cultivated land
B．interfering with natural cycle of forest life
C．forest fires caused by man’s carelessness
D．cutting the trees for building materials
小題2:"Engelmann spruce"（Para. 2） is most likely the name of .
A．a(chǎn) treeB．a(chǎn)n animalC．a(chǎn) mountainD．a(chǎn) game
小題3:The number of the deer in the Kaibab had increased enormously in  years’ time.
A．25B．6 C．18D．12
小題4:Years later,large numbers of deer in the Kaibab died mainly because of .
A．the coldB．the organized kill
C．the shortage of foodD．the poor management

American’s genius with high technology may have put men on the moon, but there is growing doubt about its ability to solve human problems closer to home.
In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world’s problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential(潛能) of the earth’s resources.
What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.
More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.
All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.
Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world’s needs, using less of the raw materials that are becoming short.
小題1:Which of the following would the author probably agree with?
A．The environment crisis will not be solved unless we stop using virgin（原始）materials.
B．In scientific research, a higher priority（優(yōu)先）should be given to understanding all living systems.
C．Exploration of outer space will finally lead to an improvement on human living conditions.
D．U. S. high-technology companies are welcoming this new change in scientific research.
小題2:Which of the following best expresses the main idea?
A．a(chǎn) growing number of Americans are doubtful about what high technology can do in solving the world’s problems.
B．Many scientists are beginning to believe that the better understanding of human beings will play a more decisive role in solving the world’s problems.
C．More and more young scientists are trying their best to find new ways to solve the world’s problems.
D．Technological creativity will still play a very important part in solving the world’s problems.
小題3:Young scientists demand that in order to satisfy human needs ________.
A．existing products be improved.
B．more complex machines and electronic equipment be designed.
C．ways be found to produce better goods using fewer raw materials.
D．a(chǎn)ny new invention and innovation be encouraged in technology
小題4:In the passage “Human problems” or “world problems” refers mainly to ______.
A．global food shortageB．resources depletion（耗盡）
C．environmental pollutionD．a(chǎn)ll of the above
小題5:The author states all the following CXCEPT that _______.
A．the development of present techniques cannot provide any answers to today’s problems.
B．a(chǎn)n increasing number of young scientists are taking a great interest in biological and social sciences.
C．many scientists have come to understand the limits of natural resources.
D．many scientists argue that high technology is something but not everything.
