Air is an odorless (無氣味的), invisible (看不見的) gas that surrounds the earth. It is everywhere on the planet. An “empty” drinking glass and an “empty” room, to give two examples, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite (明確的) shape, but, because it is matter, it takes up space. It is easy to prove that air is something that takes up space. Stuff a dry handkerchief into the bottom（底部） of a glass so that it will not fall out when the glass is turned upside-down. Push the upside-down glass; hold it straight into a jar of water till the glass is completely covered. When the glass is taken out of water, the handkerchief will be dry. The air inside the glass takes up space and keeps the water from coming in.
小題1:What does the underlined word “Stuff” (in Paragraph 2) mean?

A．Press tightly.	B．Take out.
C．Put down.	D．Turn fully.

小題2:The writer tells us that _______.

A．the experiment is done in the laboratory

B．the experiment is done outside the room

C．the experiment is easily done

D．the experiment is carried out indoors

小題3:Which of the following pictures gives us the correct result?
( W—water; A—air; H—handkerchief )

小題1:A
小題2:C
小題3:C

試題分析：文章介紹了空氣的特點，用實驗證明空氣是占據空間的。
小題1:猜詞題：從后面的句子：so that it will not fall out when the glass is turned upside-down.杯子倒過來手帕不會掉，說明是緊緊的按壓。選A
小題2:細節題：從第二段的句子：It is easy to prove that air is something that takes up space.可知這個實驗很容易做。選C
小題3:細節題：從最后一段的句子：Push the upside-down glass; hold it straight into a jar of water till the glass is completely covered. When the glass is taken out of water, the handkerchief will be dry. The air inside the glass takes up space and keeps the water from coming in.可知杯子倒過來的時候，手帕在杯子底部，杯子的其余部分是空氣。選C。

John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”
A farmer can map his fields on GPS, spotting where soil turned out to be least fertile（肥沃的） and using more fertilizer the next year in those areas where corn didn’t grow as well.
Although Ohio farmers produced more corn, it was grown on less land than in the past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit. Consumers(消費者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.
小題1:Most people usually use the GPS system for ______.

A．driving their cars

B．telling the position

C．mending the car

D．supplying the sunshine

小題2:The farmers in Ohio use GPS to ______.

A．check if the soil is fertile in some areas

B．control the rain of the place

C．water the crops if the weather is dry

D．draw the map of all the crops

小題3:Why did Ohio farmers produce more corn?

A．Because they expanded more land to grow corn

B．Because they turned to technological advances

C．Because they used more and more fertilizer.

D．Because they supplies themselves with more money.

小題4: From the passage, we can know _____.[

A．John Davis hadn’t expected a good harvest.

B．farmers grew less land than in the 1930s

C．improved seeds cost much more money

D．the output of corn in the same field is increased.

The life-long benefits of teaching children how to take care of their money make it well worth the effort. Children who are not taught these lessons pay the consequences for a life time. Some parents don’t teach children about money because they think they shouldn’t talk about money with children, don’t have the time, or think they don’t have enough money. Parents should take the time to teach children about money regardless of their income and should start when children are young.
Most people have strong feelings and opinions about money, based on childhood experiences and the values and beliefs of their families. Most often, these experiences, values, and beliefs are different for each parent. Parents should talk about these feelings and opinions and establish an unchanging approach（方式） to teaching children about money. This is important for the healthy development of children.
Here are some tips that parents can keep in mind as they begin teaching their children to manage money:
★ Guide and advise your children how to spend their money, rather than tell them what they can and cannot do.
★ Encourage and praise children rather than criticize their actions.
★ Allow children to learn by mistakes and by successes.
★ Be consistent（前后一致的） while taking children’s differences into consideration.
★ Include all family members in money management discussions, decision making, and activities that are suitable for their age. As children get older include them in discussions of limits and consequences.
★ Expect all family members to do some everyday chores based on their abilities without being paid.
★ Express your desire to have things you can’t afford. Children need to know that parents say “no” to themselves, too.
小題1:It is _____ for parents to teach their children about money management in their childhood.

A．easy

B．useless

C．too early

D．beneficial

小題2:15-year-old Harry isn’t good at managing his money. His mother is advised to _____.

A．explain to him how to manage his money better

B．pay him more money to deal with his chores

C．praise him for what he has done

D．allow him to buy what he wants

小題3:When parents discuss how to manage the family finances, they should _____.

A．include their children in the discussion

B．express their desire to have some valuable things

C．pay more attention to their children’s differences

D．try to meet their older children’s needs first

Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water—whether for drinking, agriculture, industry or the raising of fish—will always have to be met. Given this premise (前提), there are two basic routes we can go; more equal access to water or better engineering solutions.
Look at the engineering solutions first. A lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river—the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuses for their ignorance.
The engineers’ ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛區) agriculture, none of which were expected. And there average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.
The challenge for the future is to find new means of controlling water. Although GM technology(轉基因) will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?
小題1:What’s the main idea of this passage?

A．The engineering solutions to water resource and their limitation.

B．The challenge for the future.

C．The basic means of controlling water.

D．The challenge for developing crops.

小題2:The author suggests that governments will have no excuse for their careless ignorance in the future because _____.

A．The ecological destruction will be known to the public by researchers

B．The ecological destruction will no longer be a problem in the future

C．The future is an information age

D．Governments will face greater challenge in the future

小題3:Which of the following statements is NOT true for meeting our basic needs for water?

A．Water resource should be used more reasonably.

B．More dams should be built in river basins.

C．More wetlands should be protected from destruction.

D．More dry-land crops could be developed in Africa.

小題4:The last sentence probably implies that _____.

A．No one will invest in developing locally appropriate crops in Africa

B．Researchers have no interest in developing dry-land crops

C．Research on locally appropriate crops in the Third World may be profitable

D．There is less water resource in the Third World

(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（協調）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.

The art of reading fiction is largely a matter of inferring meanings. To infer means to understand facts which are not directly stated---only suggested. Inference is one of the commonest ways of knowing things: a child holds his knee and cries; this action implies his feeling; an observer infers that the child is hurt. To infer accurately in everyday life requires caution in observing; to infer skillfully in fiction requires caution in reading; both require disciplined imagination.
The short-story reader can expect to find certain basic elements in any story. For example, all stories involve a person or persons, in a particular setting, faced with a demand for a response. The response called for may be a physical action, such as defeating an adversary(對手) or escaping from a danger; or it may be a mental action, such as adjusting to others or within oneself. In either case, the short story is a description in two ways: first, it shows the motives for a given human action; second, it makes a point about the general human situation. Such descriptions, however, rather than being stated directly, usually are implied by the elements of the story.
When the reader of a story understands all the facts and their interrelationships, he is ready to infer the significance of the story as a whole---its comment on the human situation. This comment, or theme, is the seed from which the story grew. It is also the idea by which all the separate elements of the story are governed, while these in turn further shape and modify the theme. In addition to action, character, and setting, these elements include structure, mood, tone, and point of view.
Fiction reading requires an awareness of all the ways in which a story communicates. It also requires attention to detail. What the author provides is a network of points which serve as clues to his meaning. He invites the reader to develop the meaning by inference, actually to create much of the story himself and so make it part of his own experience.
小題1:According to the author, "infer" means ________ .

A．knowingfactsbeyondthestatement

B．lookingformoreevidencesforthestatement

C．findingoutadifferentmeaningfromthestatement

D．addingsomefactstothestatement

小題2:What is inferring in fiction based on?

A．Readers’guessing.	B．Thebasicelementsofthestory.
C．Thesettingofthestory.	D．Theinterrelationshipsbetweenpeopleinthestory.

小題3:What is the implied meaning of the last sentence?

A．Inferringcanreallyhelpthereaderdevelopimaginationandenrichhimself.

B．Inferringcanhelpthereaderwriteastoryofhisown.

C．Thereadershouldlookforanexperiencedescribedinthestoryhereads.

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 church	B．it gets its food
C．it sings in the forest	D．it reaches into bees' nests

小題4:What can be the best title for the text?

A．Wild Bees	B．Wax and Honey
C．Beekeeping in Africa	D．Honey-Lover's Helper

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 nature	B．the fast development of modern technology
C．how biomimcry changes our life	D．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.
