No one knows why we sleep, but it’s certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻覺(jué)).?
There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. If you feel all right, you’re probably getting enough sleep. The important thing is not to worry how much other people get—their needs may be different. Exercise doesn’t seem to increase the need for sleep—office workers, for example, sleep for about as long as people doing physically active work.?
Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns also tend(傾向) to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.
小題1:According to the passage, some people are unable to think clearly because ___________ .
A.they have hallucinations
B.they feel sleepy during the working hours
C.they don’t have enough sleep
D.they are certain to be kept from going to bed
小題2:Which of the following is TRUE?
A.All grown-ups must have at least eight-hour sleep.
B.Most of grown-ups sleep for seven or eight hours.
C.Quite a few people need only 5 hours or less for them to sleep.
D.No grown-ups sleep more than ten hours.
小題3:Whether you have got enough sleep is judged by__________.
A.how many hours you have slept
B.how many hours you need to sleep
C.whether you do exercise and physical work
D.whether you feel fresh and energetic
小題4:According to the passage, a boy of 14 years old sleeps__________.
A.a(chǎn)s long hours as a grown-up
B.much longer hours than a grown-up
C.for 14 hours each night
D.for less than 8 hours per night

A woman was walking her dog along a beach in New Zealand in late June when she saw something that looked like a white ball in the sand. It turned out to be a young Emperor penguin that was lost. At his age, he should have been close to Antarctic, swimming for fish and playing on the ice floes(冰川). But this penguin started swimming north and just kept going.
The penguin attracted a lot of attention in New Zealand. It has been 40 years since an Emperor penguin was last seen there. Researchers at the Department of Conservation were called in. They decided to watch the penguin closely, but not to disturb it in any way. Many New Zealanders came to Peka Peka Beach to look at the elegant penguin. They were careful to keep their dogs away from it so it wouldn’t be frightened.
The public nicknamed the animal Happy Feet. Researchers started to notice that Happy Feet didn’t seem well. It turns out that he had been eating the sand from the beach, likely thinking it was snow.
The public raised more than 11,000 pounds for an operation to get the sand out of his stomach. The operation was a success, and Happy Feet was taken to a zoo in Wellington, NZ. A group of experts met to decide how to help Happy Feet return to the wild.
Last Sunday, they put him on a boat called the Tangaroa, in a specially built ice-filled box and took him out into the Southern Ocean, southeast of New Zealand. There, they released him into the ocean, which is his natural habitat. He took one last look at his human helpers and then dived into the ocean.
“Emperor penguins spend their first five years at sea,” said Peter Simpson of New Zealand’s Department of Conservation. “ What happens now is up to the penguin.”
Happy Feet was fitted with a satellite transmitter(發(fā)射機(jī))so they can monitor his progress using the Internet. So far, the trackers shows that he swam northeast for a little while before getting his bearings and heading south.
小題1:Where is the young penguin supposed to appear?
A.On the sunny beach.B.Near the Antarctic.
C.Inside the hole in the ice.D.In the depths of the ocean.
小題2:The public collected some money to______.
A.build a home for the penguin
B.get the sand out of the penguin’s belly
C.do some research on the penguin
D.return the penguin to his habitat
小題3:What does Peter Simpson mean by saying “ What happens now is up to the penguin.”?
A.The penguin needs no protection from human.
B.Human beings can do noting to help penguins.
C.No one knows what will happen to the penguins.
D.Whether the penguin can survive depends on himself.

Brenda Linson never goes anywhere without an empty spectacles case. It is as vital to her as her purse. Yet, she doesn’t wear glasses. The reason she cannot do without it is that she cannot read and she cannot write. If ever she gets into any situation where she might be expected to do either of these things, she fishes around in her bag for the spectacles case, finds it’s empty, and asks the person concerned to do the reading for her. Until a few months ago hardly anybody knew about her problem. Her husband didn’t know and her children didn’t know. The children still don’t.
She had many tactics for hiding her difficult—for example, never lingering near a phone at work, in case she had to answer it and might be required to write something down.
It has never occurred to the children that their mother cannot read. She doesn’t read them stories, but then their father doesn’t either, so they find nothing surprising in the fact. Similarly they just accept that Dad is the one who writes the sick notes and reads the school reports. Now that the elder boy Tom is quite a proficient reader, Brenda can skillfully get him to read any notes brought home from school simply by asking,“What’s that all about, then?”
Brenda’s husband never guessed the truth in ten years of marriage. For one thing, he insists on handling all domestic correspondence and bills himself. A salesman for a large company, he travels a great deal and so is not around so much to spot the truth. While he’s away Brenda cores with any situations by explaining that she cannot do anything until she’s discussed it with her husband.
Brenda was very successful in her job until recently. For the last five years she had worked as waitress at an expensive restaurant, and had eventually been promoted to head waitress. She kept the thing a secret there too, and got over the practical difficulties somehow.
小題1: Brenda’s children have never found out about her problem as__________.
A.she isn’t often at home.
B.they are too young to guess the truth.
C.they find it normal to ask their father for everything.
D.they think it natural that short-sighted people like their mother don’t do much reading or writing.
小題2:What most probably made Brenda try hard to hide her difficulty?
A. Her desire to be successful in her job.          
B. Her fear of losing face.
C. Her deceitful nature.                        
D. Both A and B.
小題3:Of the following suggested titles, which is the most appropriate?
A.Brenda and Her Family
B.A Woman Who Doesn’t Wear Glasses
C.A Woman with an Empty Spectacles Case
D.The Miserable Life of a Waitress

It all began with a stop at a red light.
Kevin Salwen was driving his 14-year-old daughter, Hannah, back from a sleepover in 2006 . While waiting at a traffic light, they saw a black Mercedes Coupe on one side and a homeless man begging for food on the other.
“Dad, if that man had a less nice car, that man there could have a meal.”Hannah protested. The light changed and they drove on, but Hannah was too young to be reasonable. She pestered (糾纏)her parents about inequity, insisting that she wanted to do something.
“What do you want to do?” her mom responded. “Sell our house?”
Warning! Never suggest a grand gesture to an idealistic teenager. Hannah seized upon the idea of selling the luxurious family home and donating half the proceeds to charity, while using the other half to buy a more modest replacement home.
Eventually, that’s what the family did. The project —crazy, impetuous (魯莽的) and utterly inspiring — is written down in detail in a book by father and daughter scheduled to be published next month: “The Power of Half.” It’s a book that, frankly, I’d be nervous about leaving around where my own teenage kids might find it. An impressionable child reads this, and the next thing you know your whole family is out on the street.
At a time of enormous needs in Haiti and elsewhere, when so many Americans are trying to help Haitians by sending everything from text messages to shoes, the Salwens offer an example of a family that came together to make a difference — for themselves as much as the people they were trying to help. In a column a week ago, it described neurological evidence from brain scans that unselfishness lights up parts of the brain normally associated with more primary satisfaction. The Salwens’ experience confirms the selfish pleasures of selflessness.
Mr. Salwen and his wife, Joan, had always assumed that their kids would be better off in a bigger house. But after they downsized, there was much less space to retreat to, so the family members spent more time around each other. A smaller house unexpectedly turned out to be a more family-friendly house.
小題1:The best title for the passage should be “______”.
A.The Less, the Better
B.An Expected Satisfaction
C.Something We Can Live Without
D.Somewhat Crazy but Inspiring
小題2:What does the underlined word “inequity” most probably mean in Paragraph 3?
A.Unfairness.B.Satisfaction.
C.Personal attitude.D.Reasonable statement.
小題3: What does the underlined sentence “Never suggest a grand gesture to an idealistic teenager.” means? ______
A.Never give a quick answer to an idealistic teenager.
B.Unless a child is realistic, never give an answer immediately.
C.Give an answer if the child is reasonable.
D.Don’t respond to a child's demands firmly without consideration.
小題4: What can we learn from the last paragraph?
A.The Salwens regretted selling their house.
B.The relationship between the family members of the Salwens is much closer.
C.Small houses can bring happiness.
D.The Salwens intend to buy another big house.
小題5:Which of the following statements is TRUE according to the passage?
A.Mercedes Coupe is only an ordinary car which is quite cheap.
B.Unselfishness has nothing to do with people’s primary satisfaction.
C.Hannah asked her parents to do something charitable and they sold their house.
D.The writer’s children asked him to sell their house.

I have only once been in trouble with the law. The whole process of being arrested and taken to court was a rather unpleasant experience at the time, but it makes a good story now. What makes it rather disturbing was the arbitrary circumstances both of my arrest and my subsequent  fate in court.
It happened in February about twelve years ago. I had left school a couple of months before that and was not due to go to university until the following October. I was still living at home at the time.
One morning I was in Richmond, a suburb of London near where I lived. I was looking for a temporary job so that I could save up some money to go traveling. As it was a fine day and I was in no hurry, I was taking my time, looking in shop windows, strolling in the park, and sometimes just stopping and looking around me. It must have been this obvious aimlessness that led to my downfall.
It was about half past eleven when it happened. I was just walking out of the local library, having unsuccessfully sought employment there, when I saw a man walking across the road with the obvious intention of talking to me. I thought he was going to ask me the time. Instead, he said he was a police officer and he was arresting me. At first I thought it was some kind of joke.
But then another policeman appeared, this time in uniform, and I was left in no doubt.
“But what for?” I asked.
“Wandering with intent to commit an arrestable offence.” he said.
“What offence?” I asked.
“Theft.” he said.
“Theft of what?” I asked.
“Milk bottles,” he said, and with a perfectly straight face too!
“Oh,” I said.
It turned out there had been a lot of petty thefts in the area, particularly that of stealing milk bottles from doorsteps.
Then I made my big mistake. At the time I was nineteen, had long untidy hair, and regarded myself as part of the sixties’ “youth counterculture”. As a result, I wanted to appear cool and unconcerned with the incident, so I said, “How long have you been following me?” in the most casual and conversational tone I could manage. I thus appeared to them to be quite familiar with this sort of situation, and it confirmed them in their belief that I was a thoroughly disreputable (品行不端的)character.
A few minutes later a police car arrived.
“Get in the back,” they said. “Put your hands on the back of the front seat and don’t move them.”
They got in on either side of me. It wasn’t funny any more.
At the police station they questioned me for several hours. I continued to try to look worldly and familiar with the situation. When they asked me what I had been doing, I told them I’d been looking for a job. “Aha,” I could see them thinking, “unemployed”.
Eventually, I was officially charged and told to report to Richmond Magistrates’ Court the following Monday. Then they let me go.
I wanted to conduct my own defense in court, but as soon as my father found out what had happened, he hired a very good lawyer. We went along that Monday armed with all kinds of witnesses, including my English teacher from school as a character witness. But he was never called on to give evidence. My “trial” didn’t get that far. The magistrate (法官) dismissed the case after fifteen minutes. I was free. The poor police had never stood a chance. The lawyer even succeeded in getting costs awarded against the police.
And so I do not have a criminal record. But what was most shocking at the time was the things my release from the charge so clearly depended on. I had the “right” accent, respectable middle-class parents in court, reliable witnesses, and I could obviously afford a very good lawyer. Given the obscure nature of the charge, I feel sure that if I had come from a different background, and had really been unemployed, there is every chance that I would have been found guilty. While asking for costs to be awarded, my lawyer’s case quite obviously revolved (回轉(zhuǎn)) around the fact that I had a “brilliant academic record”.
Meanwhile, just outside the courtroom, one of the policemen who had arrested me was gloomily complaining to my mother that another youngster had been turned against the police. “You could have been a bit more helpful when we arrested you,” he said to me reproachfully (責(zé)備地).
What did he mean? Probably that I should have looked outraged and said something like, “Look here, do you know who you’re talking to? I am a highly successful student with a brilliant academic record. How dare you arrest me!” Then they, probably, would have apologized perhaps even taken off their caps, and let me on my way.
小題1:Judging from the first paragraph, the writer’s attitude towards his story is _______.
A.a(chǎn)ngryB.sad
C.a(chǎn)musedD.more than just one of the above
小題2:The first man who came up to him was ______.

Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu, which we all get now and then.

However, bird flu is a completely different story.
Ten years ago, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.
The“H”and“N”in the virus’ name refers to two kinds of proteins on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(變異). Most of the mutations only affect birds, such as chickens and pigeons, and don’t normally spread to humans. But once they do, the results can be disastrous.
“Any time an animal influenza virus crosses to humans, it is a cause for concern, ”Malik Peiris, virologist(病毒學(xué)家)at the University of Hong Kong, told Nature magazine. Take the SARS epidemic(傳染病)10 years ago as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete“stranger”to human bodies, which hadn’t developed an immunity against it.
But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地)since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.
The good news is that there’s so far no sign that the virus is spreading from person to person. But since there is no vaccine for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.
小題1:Which of the following statements is TRUE according to the text?
A.The H5N1 bird flu turned out to have something to do with the SARS epidemic.
B.More than 600 people across the world died from the H5N1 bird flu ten years ago.
C.Most of the mutations of the proteins in the bird flu virus are harmful to both birds and humans.
D.The name, H7N9 bird flu, shows that there have been new mutations of the proteins in the virus.
小題2:With the example of the SARS epidemic in Paragraph 5, the author intends to   .
A.introduce where the SARS virus came from
B.inform us of the harmful effects of the SARS epidemic ten years ago
C.show the horrible effects an animal influenza virus can have once it spreads to humans
D.compare the differences between the SARS epidemic and the H7N9 bird flu
小題3:What makes the H7N9 bird flu more frightening than the H5N1 bird flu according to the text?
A.It can cause severe sickness in birds.
B.It can spread from person to person.
C.It affects a greater number of birds.
D.It doesn’t sicken birds and thus can spread unnoticed.
小題4:What are people advised to do to protect themselves against the H7N9 bird flu?
a. To get vaccinated for the disease.
b. To keep away from birds and their eggs.
c. To stop eating chickens and ducks.
d. To avoid meeting with sick people.
e. To wash hands thoroughly and regularly.

From Avatar to Lord of the Rings, plants are no strangers to playing big movie roles. However, no one has ever shot a film that plants themselves can watch until now. In a New York art gallery, seven house plants have spent the last seven weeks watching Strange Skies, the first travel documentary for a vegetable audience. All the plants sat in the cinema in rows, enjoying themselves in Italian sunshine.
The movie was made by American artist Jonathon Keats. It consists of Italian skies recorded over two months and made into a six-minute-long movie. The film shows the clear dawn(黎明), high clouds, amazing dusk and then beautiful night. The movie has no sound and the plants, of course, do not applaud. But Stephen Squibb, a professor from Harvard University, said these plants could benefit from it—the light of the movie keeps them alive because they can continue the process of turning light into energy.
“I realized there was a much larger audience—plants—that were not being serviced, ”Keats said. “I wanted to provide plants with entertainment that companies such as Disney provide for humans. ”Meanwhile, Keats also wants to explore plants’ sensibilities(敏感性)further. He plans to open a“restaurant for plants”at a Californian museum.
One visitor, photographer Abbas Ebrahimi, admired(羨慕)the green audience, “Plants are better than us. We die and go, while in spring they come back each time. ”But when talking about the movie, he said after thinking for a few minutes, “It doesn’t mean anything to me at all. It’s just about light. For some people, it might mean something. ”
小題1:What can we learn about Keats according to the passage?
A.He is an artist from Harvard University.
B.He opened a restaurant for plants.
C.He made the film Strange Skies.
D.He liked recording Italian skies.
小題2:It can be learned that Strange Skies   .
A.has already created beautiful sound
B.was shot from dawn to dusk
C.made plants play roles in it
D.is the first travel film for plants
小題3:What did Stephen Squibb think of Strange Skies?
A.He thought it had explored plants’ sensibilities.
B.He thought it meant nothing to him.
C.He thought it could keep plants growing.
D.He thought it offered entertainment to plants.
小題4:Why did Abbas Ebrahimi admire the green audience?
A.Because they die and re-grow in spring.
B.Because they mean something to him.
C.Because there are more plants than people.
D.Because they can enjoy the movie.

The New York Philharmonic(愛(ài)樂(lè)樂(lè)團(tuán)) came to an unexpected stop on Tuesday night when an audience member’s cell phone started ringing and wouldn’t stop.
Conductor Alan Gilbert was nearing the end of Mahler’s Ninth Symphony(交響樂(lè)) when the interruption began. As eh New York Times writes, the symphony, “contains some of the most spiritual and peaceful music ever written.”
As the cell phone continued to ring, the iPhone’s signature ringtone, Gilbert stopped the entire performance. And yet shockingly the phone continued to ring. “Nothing happened,” Gilbert told the Times, “Nobody was to blame for it. It was unbelievable.”
Gilbert said minor cell phone interruptions have become common and rarely interfere with a live performance. The Philharmonic does what it can to remind to audience to turn off their cell phones before the performance begins. But the audience and performers stood by in astonished silence as Gilbert asked the offender(肇事者) to silence the phone, only to hear it continue.
Mr Gilbert said audience pointed out two people sitting where the sound was coming from. “They were staring at me firmly,” he said of the couple. Eventually, the man put his hand in his pocket and the ringing stopped.
The conductor said he asked the man if he was sure the phone was quieted. “Then he nodded his head,” Mr Gilbert said.
People in the hall had been shouting for the sound to stop. Mr Pelkonen reported that they yelled: “Thousand-dollar fine!” “Kick him out!” “Get out!”
Once the phone was finally silenced, Gilbert apologized to the audience. They responded with cheers and applause(掌聲). And the performance continued.

Starting in l972,the National Park Service established a policy for forest fires calle Natural Burn.It was acknowledged that some forest fires,such as those caused by lightning were necessary for forests to maintain balanced ecosystems,so the fire should be allowed to burn.However, a big fire in Yellowstone National Park in l988 caused this policy to be abandoned since the fire was initially allowed to burn yet soon out of control.As a result,the fire of l988 destroyed much of Yellowstone,which is America’s oldest and most beloved national park.Massive areas of plants were destroyed,and large empty spaces and acres of burned and blackened trees greeted visitors.The rivers and streams were choked with ash,and the ecosystem of the park was changed beyond repair.
In addition,great numbers of animals were killed by the fires that bumed out of control. The fires were driven by high winds,moving as many as ten miles a day.Many small animals died in the flames.The fires’ rapid advances gave the wildlife little chance to escape. Even today,few of these small forest animals have returned to live in the park. In the years immediately following the fires,the numbers of visitors declined rapidly.No one was interested in seeing a blackened and treeless park on vacation.Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America's wonder is damaged permanently.
小題1:Natural Burn was adopted because some forest fires were        
A.hard to put out
B.started by lightning
C.good for the balance of nature
D.a(chǎn)pproved by National Park Service
小題2:The big fire in Yellowstone in 1988         .
A.became out of control at first
