Most schools forbid chewing gum, but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores.
This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (腸) can.
That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and more. Scientists might even create antimicrobial (抗菌的) gums that cure bad breath.
Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake.
Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes.
The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use.
For now, Stay Alert is available only to the military (軍隊(duì)). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.
小題1: The passage mainly talks about _____.
A．the rule of forbidding chewing gum in school
B．new research on chewing gum
C．different kinds of chewing gum
D．the relationship between chewing gum and medicine
小題2: What does the underlined word “hits” in Paragraph 6 probably mean?
A．Touches.B．Attacks.C．Takes effect.D．Affects badly.
小題3:According to the passage, Stay Alert is a gum which can help people _____.
A．stay awakeB．fight colds
C．cure headachesD．overcome nervousness
小題4: It can be inferred from the passage that _____.
A．stay Alert is not easy to store
B．stay Alert needs water to swallow
C．stay Alert is available to the public now
D．we can’t buy gums that cure bad breath now

In today's world of cell phones, mini laptops and MP3 players, most people have at least one time-telling tool with them. Since these devices are so common, is time running out for the 500-year-old watch? According to some consumers, yes. New Jersey teenager Charlie Wollman says a watch is "an extra piece of equipment with no necessary function." Many young adults agree ─ and use their cell phones to tell time. Louis Galie, a senior vice president at Timex, said that fewer young people wear watches today than five years ago. As a result, some people claim that the watch industry is at a crossroads.
However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality timepiece that doesn't just keep good time. Fifty years ago, watchmakers boasted(自夸) about their products' accuracy. But in recent years, the watch industry has transformed itself into an accessory(附件，配件) business. And for many today, the image(外形) a watch communicates has become more important than the time it tells.
"Complications" ─ features that go beyond simple timekeeping ─ are an important part of a watch's image. Today's watches offer a host of features that suit almost any personality. These features include altitude trackers(追蹤器), compasses(指南針), lunar calendars, USB drives, and even devices that measure the effectiveness of golf swings!
Creativity is also a key element in today's watches. For example, Japanese watchmaker Tokyoflash makes watches that don't even look like watches. The company's popular Shinshoku model uses different color lights to tell the time. It looks more like a futuristic bracelet(手鐲) than a watch. Another Japanese watchmaker, EleeNo, makes a "handless" watch. Using a ring of circles to keep time, this watch makes an excellent conversation piece.
Whether a watch communicates fashion sense, creative flair or a love of sports, consumers want their timepieces to stand out. Nowadays, everyone has the same kind of gadget in their bags, so people want to make a statement with what's on their wrists(手腕). Will this interest in wrist fashion last? Only time will tell!
小題1:Why aren’t watches popular with young people as before?
A．Because watches cannot keep good time as cell phones, mini laptops and MP3 players.
B．Because watches are featured by the disadvantages of simple function
C．Because watches are too expensive to afford.
D．Because watches don’t have beautiful appearance as other modern time telling tools.
小題2: What does the underlined sentence in Paragraph 1 mean?
A．Watching-making is facing a survival crisis challenge.
B．Watching-making is faced with the developing opportunity.
C．Watching-making becomes the sun rising industry.
D．Watching-making has a specific development target.
小題3: It can be implied that ____________________.
A．people will gradually lose interest in watches as they grow older
B．watchmakers hardly change the development strategy for watches
C．today’s watches are better than those in the past in quality
D．customers used to be more concerned with the quality of a watch than with its image.
小題4:The following qualities can make a watch popular EXCEPT _________.
A．multifunctionB．a(chǎn)ccuracyC．nice designD．low price
小題5:What’s the best title of the passage?
A．Watches and TeenagersB．The History of Watches
C．The Accuracy of WatchesD．Watches Tell More Than Time

Are some people born clever and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both questions is yes.To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random (隨意地) from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that integigence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates (表明) that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who lives in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
小題1:Which of the following best describes the writer’s point in Paragraph One?
A．To some extent, intelligence is given at birth.
B．Intelligence is developed by the environment.
C．Some people are born clever and others born stupid.
D．Intelligence is fixed at birth, but is developed by the environment.
小題2:In the first paragraph,“no amount of special education can make a genius out of a child born with low intelligence” suggests that       .
A．no environment can change the least able into the most able
B．the difference in men’s intelligence depends on the amount of their education
C．if a person is born clever, he is certain to be a genius
D．if a person is born stupid, nothing can change him into an educated person
小題3:The last paragraph mainly shows       .
A．the importance of education
B．the relationship between environment and birth
C．the writer’s final conclusion
D．the relationship between intelligence and environment
小題4:The best title for this passage would be       .
A．Dependence on EducationB．Intelligence
C．SurroundingsD．Effect of Education
小題5:Which statement about the passage is true?
A．All twins have similar degrees of intelligence.
B．A man who is educated in university must make greater achievements than a man who works in a boring factory.
C．Proper education can change one’s intelligence at some degree.
D．Education can’t make a child born with low intelligence cleverer.

Nuclear radiation （核輻射）has a certain mystery, partly because it cannot be detected （探測(cè)）by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being at once by killing plenty of cells in important organs(器官). Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed at once. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治療) and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.
小題1:According to the passage, the danger of nuclear power lies in       .
A．nuclear mysteryB．radiation detection
C．radiation levelD．nuclear radiation
小題2:Radiation can lead to serious trouble even at the lowest level        .   
A．when it kills a few cells
B．because the killed cells can’t be replaced
C．if it damages a few cells
D．unless the damaged cells can reproduce themselves
小題3:What does the author want to tell us?
A．Radiation can hurt us.B．Radiation is a subject scientists work on.
C．Radiation is a mystery.D．Radiation is the source of cancer.

Googlefight is a simple service available on the Internet which offers you the chance to compare two different items and see how many hits they get on the Google search engine. The seemingly simple device has proved invaluable to users, especially to help win arguments.
For example, imagine that you and your friends are arguing about who are the most popular music or movie stars, you can decide the argument by writing the names in the Googlefight boxes. Let’s say that you are arguing about Jackie Chan and Jet Li. You will quickly discover that Jet Li is mentioned 16 million times on Google pages, whereas Jackie Chan is mentioned a mere 12 million times! In this unscientific way, you can claim victory for one Star over another.
But teachers have come up with ways of using Googlefight which are much more useful from an academic point of view, particularly when it comes to studying languages. You can, for example, find out the frequency of two words with the same meaning, and deduce (推斷) from the answers which one is more common. For example, let’s take the words “buy” and “purchase”, which mean the same thing (although “buy” is only a verb and “purchase” is both a verb and a noun). It is immediately clear from Googlefight that “buy” is much more commonly used, with a massive three and a half billion hits, compared to only one billion occurrences for the more formal word.
But the real value of Googlefight to the language learner is in determining which is the more common of two phrases. For example, “raining cats and dogs” is an old-fashioned English expression about the weather. Do English speakers still use it? Or are they more likely to say “pouring down”? Googlefight suggests the latter. “Pouring down” has 898,000 Google hits, whereas “raining cats and dogs” only has 326,000.
With phrases, it’s important to remember that you need to use quote marks to make the search more accurate. For example, if you type in the similar phrases “l(fā)ook after” and “take care of “ without quote marks, the second phrase seems to be more common, but with quote marks, the result is reversed.
小題1:What is Googlefight?
A．A fight between two people on Google.
B．A way to make sure you win an argument.
C．A website showing how many hits two different things have.
D．A list of all the websites on Google.
小題2:Language teachers find it useful because _______.
A．there are a lot of words on Googlefight
B．it can tell them which of the two words with the same meaning appears more often
C．some words mean the same thing
D．common words have a billion hits
小題3:What must you remember to do if you are checking phrases by Googlefight?
A．Make sure they mean be same thing.
B．Make sure they are different.
C．Remember to put quote marks round the phrase.
D．Don’t put quote marks round the phrase.
小題4:Which statement is NOT true according to the passage?
A．Googlefight is effective to determine the more common of two phrases.
B．Googlefight is a scientific way to decide an argument.
C．Quote marks can make the search more accurate.
D．Googlefight is invaluable to help win arguments.

It’s hard to track the blue whale, which has almost been killed off by commercial whaling. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior.
So biologists were delighted early this year when, with the help of the US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy’s former top secret system of underwater listening devices across the oceans.
Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.
Earth scientists announced at a news conference recently that they had used the system for closely observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. Different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope(聽(tīng)診器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.
小題1:The underwater listening system was originally designed _________________.
A．to trace and locate enemy ships
B．to observe deep sea volcanic eruptions
C．to study the movement of ocean currents
D．to replace the global radio communications network
小題2:The deep-sea listening system makes use of __________________.
A．the ability of sound to travel at high speed
B．the top-level technology of focusing sounds under water
C．the unique characteristic of layers of ocean water in carrying sound
D．low-frequency sounds traveling across different layers of water
小題3:What can we infer from the passage?
A．New radio devices are developed for tracking the blue whales.
B．Blue whales are no longer endangered with the new system.
C．Opinions differ on the use of military technology.
D．Military technology has great potential in civilian use.
小題4:What is the passage chiefly about?
A．An effort to protect an endangered marine species.
B．The civilian use of a military detection system.
C．The exposure of a US Navy top-secret weapon.
D．A new way to look into the behavior of blue whales.

Psychologists tell us that there are four basic stages that human beings pass through when they enter and live in a new culture．This process begins with the “honeymoon stage”．This is the period of time when we first arrive in which everything about the new culture is strange and exciting．We may be suffering from “jet lag” but we are thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kinds of food．This stage can last for quite a long time because we feel we are involved in some kind of great adventure．
Unfortunately, the second stage can be more difficult．After we have settled down into our new life, we can become very tired and begin to miss our homeland and our family, friends, pets．All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture．This period of cultural adjustment can be very difficult and lead to rejecting or pulling away from the new culture．
The third stage is called the “adjustment stage”．This is when you begin to realize that things are not so bad in the host culture．Your sense of humour usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place．Things are still difficult, but you are now a survivor!
The fourth stage can be called “at ease at last”．Now you feel quite comfortable in your new surroundings．You can cope（deal） with most problems that occur．You may still have problems with the language, but you know you are strong enough to deal with them．
小題1:This passage mainly talks about ________．
A．culture and foreign language learningB．a(chǎn)dventures in a foreign land

At one time, computers were expected largely to remove the need for paper copies of documents (文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. "I feel in my bones this revolution is causing more trees to be cut down," says Ted Smith of the Earth Village Organization.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.
Does all this mean environmental concerns (環(huán)境問(wèn)題) have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. " I guess people believe that the problem is taken care of, because of recycling (回收利用) " said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
小題1: The growing demand for paper in recent years is largely due to ________.
A．the rapid development of small businesses
B．the opening up of new markets
C．the printing of high quality copies
D．the increased use of the Internet
小題2:Environmentalists believe one possible way of dealing with the paper situation is ________.
A．to encourage printing more quality documents
B．to develop new printers using recycled paper
C．to find new materials for making paper
D．to plant more fast-growing trees
小題3:Hewlett-Packard Co. has decided to develop new technologies because _______.
A．people are concerned about the environment
B．printers in many offices are working overtime
C．small companies need more hard copies
D．they see a growing market for printers
