Certain animals know without analysis the difference between a number of objects and a smaller number. In his book The Natural History of Selbourne (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a kind of bird Plover’s nest, and how the mother laid another egg each day to make up for the missing one. He notes that other kinds of birds ignore the loss of a single egg, but if more than one egg has been removed, they will give up their nests. It has also been noted that a certain type of bees always provides five—never four, never six—caterpillars (毛蟲) for each of their eggs so that their young have something to eat when the eggs have hatched out. Research has also shown that both mice and pigeons can be taught to distinguish between odd (奇數(shù)) and even (偶數(shù)) numbers of food pieces.
These have led some people to think that creatures can actually count. They also point to dogs that have been taught to respond to questions about numbers with the correct number of barks.
Animals respond to quantities only when they are connected to survive as in the case of the eggs, or survive as in the case of food. They can “count” only when the objects are present and only when the numbers involved are small—no more than seven or eight. In lab experiments, animals which are trained to count one kind of objects were unable to count any other type. What interests them are the objects, not the numbers. Animals’ achievements simply are not equal to evidence of counting. They only show the results of clever, careful training.
小題1:The author refers to Gilbert’s book in paragraph 1 in order to_______.
A.support the idea that animals can count
B.show attitudes have changed since 1786
C.prove that some animals are aware of quantities
D.indicate that more research is needed in this field
小題2:The author mentions all of the following are aware of quantities in some way EXCEPT _______.
A.caterpillarsB.bees

(The Guardian):              More UK universities should be profiting from ideas
  A repeated criticism of the UK's university sector is its noticeable weakness in translating new knowledge into new products and services.
  Recently, the UK National Stem Cell Network warned the UK could lose its place among the world leaders in stem cell research unless adequate funding and legislation could be assured, despite an annual £40m spent by the Department of Health on all kinds of research.
  However, we do have to challenge the unthinking complaint that the sector does not do enough in taking ideas to market. The most recent comparative data on the performance of universities and research institutions in Australia, Canada, USA and UK shows that, from a relatively weak starting position, the UK now leads on many indicators of commercialization activity.
  When viewed at the national level, the policy interventions (interference) of the past decade have helped transformed the performances of UK universities. Evidence suggests the UK's position is much stronger than in the recent past and is still showing improvement. But national data masks the very large variation in the performance of individual universities. The evidence shows that a large number of universities have fallen off the back of the pack, a few perform strongly and the rest chase the leaders.
  This type of uneven distribution is not strange to the UK and is mirrored across other economies. In the UK, research is concentrated: less than 25% of universities are receiving 75% of the research funding. These same universities are also the institutions producing the greatest share of PhD graduates, science citations, patents and license income. The effect of policies generating long-term resource concentration has also created a distinctive set of universities which are research-led and commercially active. It seems clear that the concentration of research and commercialization work creates differences between universities.
  The core objective for universities which are research-led must be to maximize the impact of their research efforts. Their purpose is not to generate funds to add to the bottom line of the university or to substitute other income streams. Rather, these universities should be generating the widest range of social, economic and environmental benefits. In return for the scale of investment, they should share their expertise (expert knowledge or skill) in order to build greater confidence in the sector.
  Part of the economic recovery of the UK will be driven by the next generation of research commercialization spilling out of our universities. On the evidence presented in my report, there are three dozen universities in the UK which are actively engaged in advanced research training and commercialization work.
  If there was a greater coordination(協(xié)調(diào))of technology transfer offices within regions and a simultaneous (happening at the same time) investment in the scale and functions of our graduate schools, universities could, and should, play a key role in positioning the UK for the next growth cycle.
小題1:What does the author think of UK universities in terms of commercialization?
A.They have lost their leading position in many ways.
B.They still have a place among the world leaders.
C.They do not regard it as their responsibility.
D.They fail to change knowledge into money.
小題2:What does the author say about the national data on UK universities’ performance in commercialization?
A.It masks the fatal weaknesses of government policy.
B.It indicates their ineffective use of government resources.
C.It does not rank UK universities in a scientific way.
D.It does not reflect the differences among universities.
小題3:We can infer from Paragraph 5 that “policy interventions (in Paragraph 4)” refers to _____.
A.concentration of resources in a limited number of universities
B.compulsory cooperation between universities and industries
C.government aid to non-research-oriented universities
D.fair distribution of funding for universities and research institutions
小題4:What dose the author suggest research-led universities do?
A.Fully use their research to benefit all sectors of society.
B.Generously share their facilities with those short of funds.
C.Advertise their research to win international recognition.
D.Spread their influence among top research institutions.

Honey from the African forest is not only a kind of natural sugar, it is also delicious.
Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper - a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always fall to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
小題1:Why is it difficult to find a wild bees' nest?
A.It's small in size.B.It's hard to recognize.
C.It's covered with wax.D.It's hidden in trees.
小題2:What do the words "the follower" in Paragraph 2 refer to?
A.A bee.B.A honey seeker.C.A bird.D.A beekeeper.
小題3:The honey guide is special in the way ________.
A.it goes to churchB.it gets its food
C.it sings in the forestD.it reaches into bees' nests
小題4:What can be the best title for the text?
A.Wild BeesB.Wax and Honey
C.Beekeeping in AfricaD.Honey-Lover's Helper

Is language, like food, a basic human need? Judging from the extreme experiment of Frederick in the 13th century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue he told the nurses to keep silent.
All the babies died before the first year. But clearly there was more than language deprivation (剝奪,喪失). What was missing was good mothering. Without good mothering, in the first year of life especially, the ability to survive is seriously affected.
Today no such extreme deprivation exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to signals of the baby, whose brain is programmed, to mop up language rapidly. There are critical times, it seems when children learn more rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again.
Linguists suggest that speech milestones are reached in a fixed order and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ.
Recent evidence suggests that a baby is born with the ability to speak. What is special about man’s brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a teddy bear with the sound pattern “teddy bear”.
But speech has to be developed, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child’s babbling, clinging, grasping, crying, smiling, and responds to them. Insensitivity of the mother to these signals reduces the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s nonverbal (非語言的) signals is basic to the growth and development of language.
小題1:Frederick’s experiment was extreme because _________.
A.he wanted to prove children are born with ability to speak
B.he wanted his nurses to say another language
C.he was unkind to the nurses
D.he ignored the importance of mothering to the babies
小題2:The reason that some children are backward in speaking is most likely that _________.
A.they do not listen carefully to their mothers
B.their mothers do not respond to their attempts to speak
C.their brain has to absorb too much language at once
D.their mothers are not intelligent enough to help them
小題3:In paragraph 3, by “critical times” the author means _________.
A.difficult periods in the child’s life
B.moments when the child becomes critical towards its mother
C.important stages in the child’s development
D.times when mothers often neglect their children
小題4:If a child starts to speak later than others, he will _________ in future.
A.have a high IQB.be less intelligent
C.not necessarily be backwardD.be insensitive to verbal signals
小題5:If the mother seldom responds to her child’s signals, _________.
A.the child will be able to speak properly
B.the child will continue to give out signals
C.the child will invent a language of own
D.the child will make little effort to speak

What do butterfly wings have to do with computer screens? What do birds have to do with high speed trains?
These may sound like strange things to put together. But scientists, inventors, and designers are doing just that. They are learning from nature to create new technology.
The word biomimicry (仿生學) combines two words: biology and mimicry. So people using biomimicry try to use examples in nature to design new technology.
Biomimicry is not a new idea. People have been studying nature for hundreds of years. Leonardo DaVinci used birds as models to invent his flying machine. And when the Wright Brothers made the first successful airplane, they also studied birds. In 998, Janine Benyus, a natural science writer and teacher, wrote a book about biomimicry. To develop her interest in the subject, Janine Benyus started the Biomimicry Institute.
The Biomimicry Institute is a non-profit organization. It brings together scientists, designers, inventors and many other people. It offers classes to teach people biomimicry. It provides money for people to research and test new technologies. And it wants all people, from children to adults, to think about new ways to learn from nature.
People involved with the Biomimicry Institute believe that biomimicry can help solve many of the world’s problems. Often, new technologies can harm nature, but this is not true for biomimicry. Let’s look at some examples.
Butterflies have colorful wings because light shines off them in a special way. Scientists want to copy these same ways to make light shine off computers. They hope this will make for more colorful screens.
Another example of biomimicry is the bullet train. It travels at speeds of over 250 kilometers per hour! But it had a problem: it made too much noise!
Through the observation of birds, scientists thought about a kind of bird, the kingfisher(翠鳥). The kingfisher can dive into water without making any noise because of the shape of its beak(喙). Researchers thought that if they could design the front of the train like this beak, the train would be quieter. Well, it worked!
小題1:The first paragraph is written to_____.
A.start a discussion B.make a brief summary
C.introduce the topic of the text D.test readers' knowledge on science
小題2:Why did Janine Benyus set up the Biomimicry Institute?
A.To honor the Wright Brothers.
B.To show her recent inventions.
C.To gather talented people for her research.
D.To explore the link between nature and technologies.
小題3:We know from the text that the Biomimicry Institute _____.
A.earns a lot by giving classes on biomimicry B.tells people about their technologies
C.gives free support to scientists D.teaches children about birds
小題4:The author gives the two examples at the end of the text to show _______.
A.biomimcry works harmoniously with natureB.the fast development of modern technology
C.how biomimcry changes our lifeD.how nature inspires scientists
小題5:What’s the main idea of the text?
A.Biomimicry is widely used in the world.
B.People copy nature to create new technologies.
C.The Biomimicry Institute was set up for science.
D.Birds play an important part in new technologies.

Anne Whitney, a sophomore (大學二年級學生) at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go in to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer. My low grades on the tests did not show what I knew to the teacher. “Another student in biology had similar experiences. He said, "My first chemistry test was very difficult. Then, on the second test, I sat down to take it, and I was so nervous that I was shaking. My hands were moving up and down so quickly that it was hard to hold my pencil. I knew the material and I knew the answers. Yet I couldn't even write them down!"
  These two young students were experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the extreme tension and nervousness. Contrary to people’s common belief that poor grades are often a result of poor study habits, sometimes test anxiety plays a role in students’ achieving low grades. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.
  Special university advising courses try to help students. In these courses, advisors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the tests show their anxiety is high, the students can take short courses to help them deal with their tensions. These courses teach students how to relax their bodies. Students are trained to become calm in very tense situations. By controlling their nervousness, they can let their minds work at ease. Learned information then comes out without difficulty on a test.
  An expert at the University of California explains, " With almost all students, relaxation and less stress are felt after taking our program. Most of them experience better control during their tests. Almost all have some improvement. With some, the improvement is very great. "
小題1:To "blank out" is probably______.
A.to be like a blanket B.to be sure of an answer
C.to be unable to think clearlyD.to show knowledge to the teacher
小題2:Poor grades are usually believed to be the result of______.
A.poor sleeping habit B.laziness
C.test anxiety D.inability to form good study habits
小題3:Test anxiety has been recognized as______.
A.a(chǎn)n excuse for lazinessB.the result of poor study habits
C.a(chǎn) real problem D.something that cannot be changed
小題4:A University of California advisor said______.
A.a(chǎn)ll students could overcome the anxiety after taking a special test anxiety program
B.a(chǎn)lmost all students felt less stress after taking a University of California advising course
C.students found it difficult to improve even though they had taken a special test anxiety course
D.students found it easy to relax as soon as they entered a University of California advising course
