We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant (持續(xù)的）darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense(感覺) time does not depend on information from the outside world. It is inside them: a kind of "inner (內(nèi)部的）clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control（控制）the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, itaffectssuch things in our life as our need for sleep or need for food.
小題1:Before the experiment arrived at a conclusion, people had thought that the flowers would____.
A．never open in constant darkness
B．change their usual time to open
C．open ahead of the time as they usually did
D．continue to open at usual time
小題2:The sense of time that flowers have is connected with_____________.
A．its age and size
B．light and temperature
C．a(chǎn) kind of strange power(力量）inside them
D．some unknown information from the outside world
小題3:What will happen if we make good use of the "inner clock"
A．We'll need less sleep or food.
B．We'll be able to sleep as long as we wish to.
C．We'll be able to change our work time when necessary.
D．We'll have more energy to do our work better.
小題4:What's the Chinese meaning of the underlined word" affects"
A．產(chǎn)生B．影響C．給予D．依賴

小題1:A
小題2:C
小題3:D
小題4:B

When it comes to success in business and success in life, there are few qualities as important as confidence．
People naturally have different levels of confidence．Some have a higher level of confidence than others do, but even those whose confidence is lacking can learn to build their level of confidence and reach their most important goals．Increasing self confidence is one of the most common reasons people give for seeking the help of psychologists and other professionals．
One of the many places where a greater level of confidence is useful is in the workplace．We all know how difficult it can be, for instance, to ask the boss for a raise．This process can be extremely difficult for those who lack confidence in their own abilities．After all, if you are unsure about your own abilities, how will you ever convince your boss that you deserve more money for the work you do?
Even if you are not asking for that big raise, having plenty of confidence in your abilities is important to success．If you are certain of your abilities, chances are that those around you, whether they are your coworkers, your colleagues or your superiors, will see that confidence, and that will help to assure them that you are the best at what you do．
Being thought of as the person to go to, and being seen as an expert in your chosen field, is naturally very important to success on the job．If you can make yourself the person people go to for guidance and advice, you will help to protect yourself from the ever present danger of downsizing（裁員）．After all, if you are a recognized expert at the office, you will be regarded as an indispensable member of the team．
Having a high level of confidence, after all, does not mean overlooking the places where you could improve．Knowing what you do well and where you need help will help you enjoy increased success and confidence．

According to US research, it can take up to ten years to become a near-native English speaker. Asian and Spanish students took between five and ten years to reach native speaker performance in English-only schools. Fluency obviously doesn’t happen overnight. But time can definitely make you a better speaker.
After testing his own memory, German psychologist Hermann Ebbinghaus discovered that humans forget most of what they learn in the first 20 minutes.
So cramming right before a speaking exam is not likely to be as effective as practicing regularly over time. The more you practice, the more familiar new words will become. In the classroom, studies have also shown that repeating oral tasks improves a speaker’s performance.
One of the best repetition exercises is the 4/3/2 technique. Speakers give the same talk to three different listeners with a progressive decrease in delivery time, starting at four minutes, then three, and finally two minutes. This exercise has been proven to help learners speak faster. It can also result in less hesitation and more grammatical accuracy. While time dose make a difference when it comes to speaking perfect English, it would not hurt to brush up on your other language skills.
Studies have also shown that reading can increase your speaking vocabulary. After one month of an extensive reading program, a 27-year-old student of French became more familiar with 65 percent of the new words.
Aside from choosing the right learning methods, having certain personality traits may also help. US linguistics expert Stephen Krashen believes those with high motivation, self-confidence and a low level of anxiety are better equipped for speaking success.
Krashen says students who don’t have these qualities are more likely to have a “mental block”. “Even if they understand the message, the input will not reach the part of the brain responsible for language acquisition,” he writes in his book Principles and Practice in second Language Acquisition.
小題1:According to the passage, if you want to be a near-native speaker, you need _____.
A．long-term speaking practice and much reading
B．speaking practice for ten years only
C．long-term speaking practice, much reading and certain qualities
D．cramming new words every day
小題2:The author put forward the 4/3/2 technique just to show that _____.
A．you should speak to 3 different people
B．you should speak to 3 different people at 3 different times
C．it can prevent you from making grammar mistakes
D．it is really a good way to make you a better speaker
小題3:The example of a 27-year-old student of French in the passage mainly means that _____.
A．reading can enlarge your vocabulary for your speaking
B．reading can make you memorize just 65 percent of the new words
C．the 27-year-old student of French is very clever
D．in one month, you can improve your speaking ability
小題4:The underlined phrase “l(fā)inguistics expert” means a person who is quite expert at _____.

Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback. Simply speaking, it means the longer kids are out of school, the more they forget. The only thing they might gain is weight.
Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.
But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, "Year-round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year."
Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.
But calling them "summer school" could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like "summer camp," "enrichment," "extra time" and "hands-on learning."
小題1:According to the first paragraph the summer learning gap         .
A．helps children to gain weight
B．leads children to work harder
C．improves children’s memories
D．a(chǎn)ffects children’s regular studies
小題2:Compared to traditional schools, students in the year-round ones          .
A．perform better and have more learning gains
B．have much less time for relaxation every year
C．have generally the same number of class days
D．hold more classes with more free weeks off
小題3:Which of the following statements is true?
A．Students from poor families often fall behind after the vacation.
B．Year-round schools can solve the problem of the learning gap.
C．There are schools in each state following a year-round calendar.
D．Nothing can help the students who fall behind after the vocation.
小題4:Why did almost all parents dislike the term “summer school”?
A．They cherish the children’s rights of freedom very much.
B．They are worried about the quality of the “summer school”.
C．They want their children to be forced to make up the gap.
D．They can’t afford to the further study during vacation.
小題5:What would be the best title of this passage?
A．Opening Summer Camps
B．Forbidding Summer Schools
C．Spreading Year-Round Education
D．Minding the Summer Learning Cap

Have you wondered why different animals or pests have their particular colors? Colors in them seem to be used mainly to protect themselves.
Birds, especially seagulls are very fond of locusts, but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves, bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the color much like the barks(樹皮) of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.
小題1:This passage mainly talks about ______.
A．the change of color in locusts
B．the protective coloration of animals and pests
C．how a certain sea fish protects itself
D．a(chǎn)nimals or pests can dye themselves different colors
小題2:Locusts are ______ but they aren’t easily wiped out(消滅)by their enemies because _______.
A．a(chǎn)nimals; they are powerful enough
B．beasts; they are dangerous to their enemies
C．pests; they take on the same colors as crops
D．birds; they fly very fast
小題3:What does the underlined word “invisible” in Paragraph 3 mean?

What would life be like without rich, creamy, mouthwatering, melt-in-your-mouth chocolate?
Life would be bitter for most Americans. They spend about $13 billion a year buying all sorts of chocolate treats.
However, for the African children who toil under slavelike conditions on cacao plantations, life is not sweet. The cacao bean is the main ingredient in the chocolate. According to a 2002 survey by the International Institute of Tropical Agriculture and the US Agency for International Development, about 284,000 children work in dangerous conditions on cacao farms in western Africa.
More than half those children are younger than 14. Many were sold into forced labor to work 12 hours or more a day on the cacao plantations.
A number of international organizations, including several African governments, recently began a program to eliminate(消除) child labor on cacao plantations. Under the program, government officials will remove children from abusive working situations while teaching farmers about child labor issues.
The program will also make borrowing money easier for cacao farmers. Officials hope farmers will use the money to invest in their farms and hire paid laborers.
小題1:The cacao bean is the main ingredient in _______.
A．treats
B．coffee
C．chocolate
D．cigarettes
小題2:How many children under 14 work on cacao farms in western Africa?
A．About 284,000.
B．About 142,000.
C．About 467,000.
D．About 876,000.
小題3:From the passage, you can reasonably conclude that _______.
A．cacao farms in western Africa rely heavily on child labor
B．children in Africa know how to make the best chocolate
C．candy bars sold in the United States are made on plantations in Africa
D．eating too much chocolate is bad for your health

A new era is upon us. Call it what you will: the service economy, the information age, the knowledge society. It has changed the way we work. Already we’re partly there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the breadth (廣度) of the economic transformation can’t be measured by numbers alone, because it also is giving rise to a basic new way of thinking about the nature of work itself. Long-held concepts about jobs and careers, the skills needed to succeed, even the relation between individuals and employers — all these are being challenged.
We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip (芯片), would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more important, and the people who possess it, whether they work in manufacturing (制造業(yè)) or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information services will be predominant (最重要的). It will be the way you do your job.
小題1:One of the great changes caused by the knowledge society is that ______.
A．most people have to take part-time jobs
B．people have to change their jobs from time to time
C．people’s traditional concepts about work are no longer completely true
D．the difference between the employee and the employer has become unimportant
小題2:The future will probably belong to those who ______.
A．have more brains
B．a(chǎn)re involved in the service industries
C．cast their mind ahead instead of looking back
D．possess and know how to make use of information
小題3:Which of the following would be the best title of the passage?
A．Computers and the knowledge society
B．Features and meanings of the New Era
C．Service Industries in the Modern Society
D．Rapid Advancement of Information Technology

When most people think of giant pandas, the pictures of the cute, black-and-white bears from China that eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are interested in what they leave behind: their poop(排泄物). At a recent meeting in Denver, Professor Brown at the university presented her research showing how panda poop could inspire a new way to obtain energy from plants, which are a renewable energy source. Usually, plants can be called biomass(有機(jī)燃料) when they are used as an energy source.
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists something about breaking down biomass. Pandas—or at least the bacteria in their stomachs—are very good at getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two pandas, YaYa and LeLe living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break down biomass, including one that had never been found in pandas. Brown says that because the poop contains bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn biomass—like grass or other plants—into fuel.
Brown says she doesn’t mind handling panda poop. “It’s probably the most pleasant material to work with,” she says, “My colleagues and I have been working with other poop for a long time, and we can assure you it has a fairly pleasant smell associated with it.”
小題1:The importance of studying panda poop is _______.
A．to create a renewable energy from plants
B．to explore a new way to get energy from plants
C．to learn a lesson of energy from panda poop
D．to figure out how the bacteria work for us mankind
小題2:The process of the panda poop project can be described as ______.
a. Identify the chemicals helpful to break down biomass.
b. Find the bacteria in panda poop which break down bamboo.
c. Reproduce the chemicals in the lab to turn biomass into energy.
d. Analyze how the bacteria in panda poop work in panda’s stomach.
A. a, b, d, c          B. a, d, c, b          C. b, a, d, c          D. b, d, a, c
小題3:What does the author mainly want to express in the 2nd paragraph?
A．Pandas don’t digest bamboo the same way as cows.
B．Pandas are capable of getting energy using stomachs.
C．Pandas can get energy from bamboo more efficiently.
D．Scientists have learnt something new from panda poop.
小題4:What does Professor Brown think of working with panda poop?
A．SickB．ChallengingC．InspiringD．Enjoyable

Have you ever wondered why the roots of the plants always know which way to grow—into the soil but not above it? Some British scientists have recently solved this mystery.
It turns out that roots have special hairs that tie them into the soil and help them grow their way past obstacles, a team at the John Inners Center in Norwich reports in the February 29 issue of Journal Science.
“The key is in the fuzzy(有絨毛的)coat of hairs on the roots of plants,” says professor Liam Dolan. “We have found a growth control system that enables these hairs to find their way and to become longer when their path is clear.”
Root hairs explore the soil in much the same way a person would feel their way in the dark. If they come across an obstacle, they make their way around until they can continue growing in an opening. In the meantime, the plant is held in place as the hairs grip(緊緊抓住)the soil.
The hairs are guided by a clever chemical trick. A protein(蛋白質(zhì)) at the tip of the root hairs called RHD2 helps them to take calcium(鈣) from the soil. Calcium makes the hairs grow, and produce more RHD2, and take more calcium.
But when an obstacle blocks the hair’s path, or the hair reaches the surface of the soil, the cycle is broken and growth starts in another direction.
This system gives plants the flexibility to explore a complex environment and to live in even the most unpromising soils, says Dolan.
In poor soils such as in parts of Australia and Africa, native plants have adapted by producing enormous numbers of root hairs. A better understanding of this adaptation will allow scientists to develop hairy rooted crops that can grow in unfriendly environments.
According to Dolan, “Research in the John Inners Center is taking a breeding approach to increase hair length in wheat but it will be some time before new cultivars(栽培變種) are developed.”
小題1:The passage is mainly about _______.
A．why the roots of plants grow into the soil but not above it
B．how the roots of plants grow into the soil but not above it
C．the process of plants growth
D．a(chǎn) growth control system of plants
小題2:How does the circle work?
A．RHD2 takes calcium from the soil, which makes hairs grow, and produce RHD2 and take more calcium
B．Roots take RHD2 and calcium from the soil and produce RHD2
C．Roots make hairs grow, and produce RHD2, and take more calcium
D．RHD2 takes protein, which makes hairs grow, and produce RHD2, and take more calcium
小題3:We can infer from the last paragraph that ________.
A．hairy rooted crops can grow better in unfriendly environments
B．a(chǎn) new cultivar of wheat with long hair has been developed by scientists
C．a(chǎn) new cultivar of wheat with long hair is still on test
D．the roots of plants always know which way to grow
