Do your children always sit still and watch TV? If so, you should be very alert!
Nowadays, children watch television for long hours. They often spend evenings watching their favorite programs on TV. Sometimes they might stay up late to watch TV. Their addiction to television results in their not having time to play or do exercise. They should go outside with friends or spend time reading books. Moreover, watching television too much is harmful to their eyesight.
Researchers claim that attention deficit disorders in children are a result of watching too much television. They say that watching television leads to a developmental disorder in the part of the brain which is responsible for language skills. Children who watch television more and read less have greater difficulty paying attention and concentrating. Children that spend long hours watching television are more likely to be affected by attention deficit disorders.
Television is one form of media which is used to show all kinds of products. Watching too much television can lead to early exposure to a wide variety of things. Television advertisements may cause children to behave incorrectly or damage themselves. Advertisements about fast food, cold drinks or other such products that are not good for children’s health can have a bad effect on them. Some TV shows and films also affect how children think and behave.
Studies in psychology have shown that certain programs can have a long-lasting effect on children’s minds. Horror scenes and other frightening shows can have a negative effect on the minds of children watching them.
Television is a means of recreation but watching it too often is harmful to children’s physical and mental health. You need to help you children deep a balance of everything in life.

Most earthquakes occur within the upper 15 miles of the earth’s surface, but earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much.
The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set (堅立架), it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir was not strong, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.
There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic (地震的) sea waves, or tsunamis (海嘯). These are often called tidal waves, but the name is incorrect. They had nothing to do with tides. In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them “tsunamis” meaning “harbor waves”, because they reach a sizable (相當(dāng)大的) height only in harbors.
Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An earthquake warning system is in use to warn all shores likely to be reached by the waves. But this only enables people to leave the threatened shores for higher ground: There is no way to stop the oncoming wave.
小題1:Which of the following can NOT be concluded from the passage?
A．The number of earthquakes is closely related to the depth.
B．Roughly the same number of earthquakes occur each year.
C．Earthquakes are impossible at depths over 460 miles.
D．Earthquakes are most likely to occur near the surface.
小題2:The destruction of Agadir is an example of       .
A．faulty building construction
B．a(chǎn)n earthquake’s strength
C．widespread panic in earthquakes
D．ineffective instruments
小題3:According to the passage, the waves caused by submarine earthquakes are not noticeable out at sea because of       .
A．their high speed
B．the wide shores
C．their silent movements
D．their long wave length
小題4:The significance of the slow speed of tsunamis is that people may      .
A．help reduce fear
B．find ways to stop them
C．be warned early enough
D．develop warning systems
小題5:According to the passage, the number of factors that may determine the extent of the disaster in an earthquake is      .
A．two B．fiveC．four D．three

In the computer age, most of us take a broadband（寬帶）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “l(fā)ast mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纖電纜) promise to bring extremely fast Internet connections to more users.
Still, the “l(fā)ast mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (跡象), it may not be too long before an Internet connection simply follows you wherever you go.
小題1:The underlined part “a catch” (in Paragraph 2) probably means “_____”.
A．a(chǎn) rare challengeB．a(chǎn) desirable planC．a(chǎn)n efficient deviceD．a(chǎn) hidden problem
小題2:What can we know from the third paragraph?
A．Internet connection has not been popular in most cities.
B．Internet service providers care about rural（農(nóng)村的）customers.
C．Computer is popular in developing countries.
D．It is hard to bring Internet access to users in remote areas.
小題3:Paragraph 4 mainly tells us that technological advancements _____.
A．make TV and telephone available everywhere
B．bring great change to people’s everyday life
C．make it possible for more people to use the Internet
D．bring faster Internet connections to users
小題4:What may eventually settle the “l(fā)ast mile” problem?
A．The broadband connection’s getting faster.
B．More and more Internet users.
C．more and more Internet connections.
D．The rapid progress in cell phone technology.

What will man be like in the future—in 5000 or even 50, 000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago , was shorter than he is today. Now, on average,  men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modem world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’ s capacity(容量). As time goes on , however , we shall have to use our brains more and more,  and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact , we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’ s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however , our fingers will grow more sensitive（敏感的） because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. …
小題1:The passage mainly tells us that _______.
A．man’s life will be different in the future.
B．future man will look quite different from us.
C．man is growing taller and uglier as time passes.
D．human’s organs’ functions will become weak “
小題2:The change in man’s size of forehead will probably be because ___________.
A．he makes use onIy20% of the brain’s capacity.
B．his brain has grown larger over the past centuries.
C．the other 80% of his brain will grow in due time
D．he will use his brain more and more as time goes on :
小題3:What will be true about a human being in the future?
A．He will be hairless because hair is no longer useful.
B．He will have smaller eyes and will wear better glasses.
C．His fingers will grow weaker because he won’t have to make use of them.
D．He will think and feel in a different way.
小題4:It is implied that ________.
A．human beings will become less attractive in the future
B．less use of a bodily organ may lead to its degeneration(退化,)
C．human beings hope for a change in the future life
D．future life is always predictable

Throughout seafaring history, ships and sailors have been lost to storms, accidents and war. Until recently, most of these ships were weak wooden sailing vessel (船只), their skeletons(骨架) quickly eaten away by sea creatures. Now, large vessels made of steel float on the seas. Thousands of these huge ships have been lost in times of war and in times of peace.
The bones of great metal ships, unlike the wooden vessels of old, survive the destruction of the sea long enough to become home and harbor for underwater life of all kinds. Shipwrecks(殘骸) often provide the only hard surface and structure at the sandy bottom of the sea, something many sea creatures need.
The ship has been underwater for only five days. Its surface is still clean. Six weeks later, the wreck is covered with a slimy layer of algae(海藻), but it is still recognizable as a ship. Soon, animals that need to attach themselves to a hard surface, like the feather duster worms, make the wreck their home.
In warm waters, coral polyps(珊瑚蟲) settle on the wreck and begin the process of building a rock-like crust on the ship. Small fish are attracted on all of these creatures. Larger fish come to feed on these small fish that hide in the wreckage. Eventually, the largest animals are attracted to the rich life on the shipwreck.
Shipwrecks give us valuable information about how sea plants and animals develop. We know exactly how long this wreck has been under water and how long sea life has been growing on it. Yet even the strongest steel shipwreck will finally be destroyed by the flows of water. But long after this wreck has been broken apart, it will still act as a reef (礁石). Layer upon layer of sea life has formed a structure that is now more natural than artificial, and will remain an island of life under the sea.
小題1:Which of the following is NOT TRUE about shipwrecks?
A．Most ships in ancient times sank easily and become shipwrecks.
B．Shipwrecks, for scientists, are worth researching to get valuable information.
C．The skeletons of old wooden shipwrecks will exist for quite a long time.
D．Some sea animals tend to seek food on the shipwrecks.
小題2:The writer’s purpose in writing the article is to tell us_____.
A．the differences between the ancient vessels and the modern ones
B．how the ships become shipwrecks at sea
C．how coral polyps live on the wreck in warm waters
D．the value of studying shipwrecks at the bottom of the sea
小題3:Which of the following is closer to the underlined “crust”?
A．a(chǎn) hard outer coveringB．the skin of a rock
C．a(chǎn) hole in a shipD．a(chǎn) small house
小題4:What will happen to shipwrecks in the end?
A．They will be pulled out of the sea for research.
B．They are likely to disappear and form reefs.
C．They will become an island under the sea.
D．They will be like works of art.

For all dinner tables, a glass of milk seems to be a must. At least it was when I was growing up. It is widely believed that milk is a must in building strong bones and teeth. There’s no doubt that dairy products, especially milk, are high in protein and calcium, and Vitamin D and Vitamin A are added to most milk products.
While it’s well known that our bones need calcium, some studies suggest that high calcium intake doesn’t necessarily lower a person’s risk for fractures（骨折）. A Harvard study found that people who drank two or more glasses of milk had no greater protection from breaking a bone than those who drank a glass or less a week.
There is no doubt that we need calcium. Some anti-dairy supporters claim dairy products can lead to heart disease. Much of this claim is based on high-fat dairy products, like cheese and cream, which may indeed lead to some health problems. Some studies have linked high milk intakes with a risk of prostate cancer; this seems also to be caused by high-fat dairy products, but not by dairy products in general.
Although milk has always been regarded as the most important thing we need for our bones, one of the most important things in strengthening bones and reducing the risk of osteoporosis（骨質(zhì)疏松）is weight-bearing exercise, such as jogging, walking, and weight lifting.
Perhaps we should think of dairy products as less like a nutrient and more like a food. If you like it, eat it. If not, find something else to eat. Some claims may not be completely true. When I eat cream, I’m not thinking about calcium, protein, or any such thing. I’m thinking it is delicious.
小題1:What is the best title for this passage?
A．Milk: is it really necessary for children?B．The disadvantages of drinking milk.
C．Milk causes health problems.D．Milk: is it really good for the body?
小題2:For people who want to reduce the risk of osteoporosis, we can infer that the writer may suggest that they ________.
A．a(chǎn)void milk with Vitamin D and Vitamin A added
B．spend some time exercising
C．take in as much calcium as possible
D．drink more than two glasses of milk every day
小題3:Based on the passage, we learn the writer may agree that ________.
A．milk is the most important thing that we need for our bones
B．children should not be permitted to eat cream
C．milk should be considered more like a food than a nutrient
D．children should drink milk whether they like it or not
小題4:What can we learn from the passage?
A．Some dairy products may harm our health.
B．Milk has the highest level of protein of any food.
C．The writer seldom drank milk when he was young
D．People who drink milk every day are at a high risk of getting a heart disease.
