Howling is a behaviour commonly observed among a wolf pack. As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There are different explanations of a wolf’s howl and it appears that there may be more to discover.
One theory is that wolves howl to bond better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behaviour.
Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be “punished” for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status a
mong its members? —Why do wolves howl for sure?
What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves all howl together to report their presence.
小題1:What is the possible similarity between wolves’ howling together and humans’ singing in chorus?A.The act of calling each other. B.The sense of accomplishment. C.The act of hunting for something. D.The sense of belonging to a group.
小題2:Why does Harrington think the “social bond” theory may be wrong?A.Wolves separate from each other after howling. B.Wolves tend to protect their huntin
g grounds. C.Wolves sometimes have quarrels after howling together. D.Wolves of low rank are encouraged to join in the chorus.
小題3:Researchers are sure that wolves often howl to ______.A.show their ranks B.find their companions C.report the missing ones D.express their loneliness
小題4:“Howling… is a contagious behaviour” (in the last paragraph) means _______.A.howling is a signal for hunting B.howling is a way of communication C.howling often occurs in the morning D.howling spreads from one to another

It doesn’t matter when or how much a person sleeps, but everyone needs some rest to stay alive. That’s what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true? The doctors decided to see this strange man themselves.
Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.
The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by his strange continuous sleeplessness. They asked him a lot of questions, hoping to find an answer. They found only one answer that might explain this question. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.
Herpin died at the age of 94.
小題1:The doctors came to Herpin’s home in order to __________.A.treat him for his illness B.find the reason why some old people didn’t need any sleep. C.get some proof to show his sleeplessness was not really true. D.help him to have a rest in some day.
小題2:After watching him closely, the doctors came to believe that Al Herpin ________.A.needed some kind of sleep. B.needed no sleep at all. C.was too old to need any sleep. D.often slept in a chair.
小題3:Al Herpin’s condition could be regarded as ___________.A.a(chǎn)n unusual one B.a(chǎn) common one C.very healthy D.very funny
小題4: The main idea of this passage is that ____________. A.large numbers of people do not need sleep B.everyone needs some sleep to stay alive C.people can live longer by trying not to sleep at all D.a(chǎn) person was found who actually didn’t need any sleep

In the computer age, most of us take a broadband 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 de
veloping 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 challenge B.a(chǎn) desirable plan C.a(chǎn)n efficient device D.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 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.

Scientists warn today that the Atlantic bluefin tuna(金槍魚)faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined.
The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as £ 52,000 in the Tokyo fish markets. “In my lifetime, we’ve brought this big fish to the doorstep of death in the western Atlantic Ocean,” said Barbara Block of Stanford University in California. “The electronic way of tracks provides the best scientific information we’ve ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. ”
Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna—in the Mediterranean and Japan—have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked.
So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. “There are two ways to save the Atlantic bluefin tuna—protect them in their production grounds and in their feeding grounds,” Prof. Block said. “This will need immediate action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna produce as separate populations. ”
小題1: The bluefin tuna in this passage mainly refers to the one _______. A.in the Atlantic B.in the Pacific C.in the Gulf of Mexico D.in the Mediterranean
小題2:Which of the following is NOT true according to this passage?A.The bluefin tuna is a kind of large and heavy fish. B.The number of the bluefin tuna in the sea is getting smaller and smaller. C.Scientists are worried about the future of the tuna. D.Scientists think that the harvest of the seas will remain good.
小題3:According to Professor Block, tuna can be saved by ______. A.finding a new way to protect them B.controlling the catches of them C.reducing the population to eat them D.protecting them in their production and feeding grounds
小題4:The purpose of the passage is to ______. A.tell people a new way has been found to save the bluefin tuna B.call for action to save the bluefin tuna C.warn people not to eat tuna sandwiches anymore D.help scientists to find a new way to save the bluefin tuna

As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治療的) stem cells.
In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(細(xì)胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.
小題1:The best title of this passage probably is _______.A.The importance of clone B.First insects are cloned C.The disagreement in clone D.The advantages of clone
小題2:The scientists cloned flies because________.A.there are fewer and fewer flies in the world B.flies are easy to find and cheap to use C.they can gain some experience before cloning other animals D.it is safe to clone flies
小題3:The failure of most cloned animals is due to _______.A.the difference of other animals’ genes B.the improper technique of clone C.the complex of other animals D.the improper rearrange of the adult gene
小題4:It can be inferred from the last paragraph that ______.A.the clone of insects before used grown-up cells B.the clone of insects were never experimented before C.this time scientists cloned flies successfully and easily D.based on this success, other animals will be cloned in large quantities.
