"Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. Don’t read in dim (暗的)light! This is one of the “pearls of wisdom” that are supposed to help us live a healthy life. Such common beliefs, however, lack scientific basis, according to a paper published recently in the British Medical Journal.
Do you believe in the following everyday wisdom?
Reading in dim light ruins your eyesight.
In dim light, you might blink (眨眼) more, feel discomfort from drying and have trouble focusing. But the majority of eye experts believe it is unlikely to do any permanent damage.
We must drink at least eight glasses of water a day
In 1945, the Nutrition Council in US suggested that people need to consume 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total.
We only use 10 percent of our brains.
This myth arose as early as 1907. People have long argued about our power of self-improvement and our brains’ potential abilities. But detailed imaging shows that no area of the brain is silent or inactive.
Shaving your legs causes hair to grow black faster and thicker.
This theory is also illusion. Shaving has no effect on the thickness or rate of hair growth,
studies say. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer (更細). So hair that is newly grown gives the impression of darkness.
小題1:What does the paper say about some common beliefs?
A．They are pearls of wisdomB．They help us live in healthy ways
C．They are well-known theories.D．They do not have scientific basis.
小題2:Which of the following is true according to the passage ?
A．Reading in dim light does harm to one’s eyes.
B．People need a total of 2.5 litres of water a day
C．People use 90 percent of their brains.
D．Shaving your legs will give you thicker hair.
小題3:This passage is most likely to be found in __________ ?        
A．a(chǎn) newspaperB．a(chǎn) science fiction

Bertie knew there was something in the wind. His mother had been sad in recent days, not sick，just strangely sad. The lion had just lain down beside him，his head warm on Bertie’s feet，when Father cleared his throat and began, “You’ll soon be eight, Bertie. A boy needs a proper education. We’ve found the right place for you, a school near Salisbury in England. ”
His heart filled with a terrible fear, all Bertie could think of was his white lion. “But the lion,” he cried, “What about the lion?”
“I’m afraid there’s something else I have to tell you, ” his father said. Looking across at Bertie’s mother, he took a deep breath. Then he told Bertie he had met a circus owner from France, who was over in Africa looking for lions to buy. He would come to their farm in a few days.
“No! You can’t send him to a circus!” said Bertie. “People will come to see him. He’ll be shut up behind bars. I promised him he never would be. And they will laugh at him. He’d rather die. Any animal would! ” But as he looked across the table at them, he knew their minds were quite made up.
Bertie felt completely betrayed (出賣). He waited until he heard his father’s deep breathing next door. With his white lion at his heels，he crept (躡手躡腳地移動) downstairs，took down his father’s rifle (步槍) and stepped out into the night. He ran and ran till his legs could run no more. As the sun came up over the grassland, he climbed to the top of a hill and sat down, his arms round the lion’s neck. The time had come.
“Be wild now”，he whispered. “You’ve got to be wild. Don’t ever come home. All my life I’ll think of you. I promise I will. ” He buried his head in the lion’s neck. Then, Bertie climbed down the hill and walked away.
When he looked back, the lion was still sitting there watching him; but then he stood up, yawned, stretched, and sprang down after him. Bertie shouted at him, but he kept coming. He threw sticks. He threw stones. Nothing worked.
There was only one thing left to do. With tears filling his eyes and his mouth，he lifted the rifle to his shoulder and fired over the lion’s head.
小題1:Bertie’s mother was sad probably because she _____.
A．had been seriously ill recently
B．had decided to send Bertie to school
C．knew Bertie would hate to go to England
D．knew selling the lion would upset Bertie
小題2:The underlined word “they” in Para. 4 probably refers to _____.
A．other animalsB．some audienceC．Bertie’s parents D．circus owners
小題3:In the last paragraph, the boy lifted the rifle to _____.
A．threaten the lion back to the wildB．kill the lion out of fear
C．protect himself from the lionD．show his anger towards his father
小題4:The passage intends to show that _____.
A．a(chǎn)nimal-hunting is popular in Africa
B．parents are sometimes cruel to their children
C．people and animals can be faithful to each other
D．a(chǎn)nimals usually lead a miserable life in circuses

閱讀下面短文并回答問題,然后將答案寫到答題卷相應(yīng)的位置上(請注意問題后的字數(shù)要求)。
Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It’s wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn ____________：butterfly, backstroke, breaststroke, and crawl. I feel that one of these—the breaststroke—is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming, there are certain rules every swimmer should follow:
(1) Never swim alone! No matter how good you are in the water, don’t risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble.
(2) Don’t go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach. Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive.
(3) Don’t smoke. Swimming depends on a healthy body; good lungs are part of it.
(4) Work at any activity that builds muscles.
小題1:What is the main idea of the passage? (no more than 10 words)
___________________________________________________________ 
小題2:Please complete the following statement with proper words. (no more than 5 words)
__________________________and the recognition of its danger are sensible.

I fell in love with Yosemite National Park the first time I saw it, when I was 13 . My parents took us there for camping.

That has been my life’s passion ever since— 38  the rocks and mountains of Yosemite. I’ve long made Yosemite my  39 .

Learning to drive is important to the independence of teenagers, but it is also a great responsibility．Although having a law that keeps 16-year-old drivers from having more than one teenager in the car with them at first seems unfair, there are convincing reasons for this requirement．
The Insurance Institute for Highway Safety reports that teens are four times more likely than older drivers to be involved in an automobile accident．It also reports that 16-and 17-year-old drivers are twice as likely to have an accident if they have two teenage friends in the car and four times as likely to have one if they have three or more teenage friends in the car with them．Fatal （ 致命的） crashes of 16-year-old drivers involve the highest percentage of speeding, driver error, and number of passengers．This information is enough to cause any reasonable person to wonder about the wisdom of allowing new teen drivers to take a carload of friends anywhere, even if the law permits it．
A study at the National Institutes of Health indicates that the part of the human brain that controls judgment and evaluates the consequences of our actions might not be fully formed until the age of 25．Until this study, researchers had placed the age at 18．If this is true, it could explain the reckless （魯莽的） behavior of many teens, behavior that often extends into their twenties．It also could be a strong reason for being cautious about the driving circumstances of young people．
This is not the only study that indicates such caution is necessary．One study at Temple University in Philadelphia examines the results of peer（同齡人） pressure in risky driving situations．The study, which uses a driving game, has an individual guide a car through a course, both alone and in the presence of friends．Three different age groups participated in the study: 13-16, 18-22, and 24 and older．Members of the oldest group showed caution whether driving alone or with friends present, but the two younger groups took more chances when they were with their friends．Furthermore, because these drivers were accustomed to the noise and distraction of many passengers, they were unable to see their own mistakes．Once again, this is a good indication that a law restricting the number of teenagers in the car with a young driver is a good idea．
小題1:What does the author mainly tell us in Paragraph 2?
A．Many deaths have occurred because of inexperience and overconfidence．
B．It' s reasonable to severely limit the passenger number of teen drivers．
C．New teen drivers have to ask permission before driving with friends．
D．There are many causes behind the teens' driving accidents．
小題2:From the two studies, the author probably suggests that ______．
A．different age groups have different peer pressure
B．teenagers often give wrong judgments above passengers' noise
C．underdeveloped brain makes teens ignore their mistakes
D．driving circumstances are bound up with（與…密切相關(guān)） the risk of accidents
小題3:We can infer that the law restriction can probably ______．
A．protect teens on the highway
B．raise teens' sense of responsibility
C．reduce the number of fatal crashes
D．force teens to drive with caution
小題4:With which statement would the author most likely disagree?
A．Some teenagers have risky behavior while driving．
B．Certain laws treat teenagers and adults differently．
C．We still need more studies on teen driving．
D．Driving is important to a teenager' s sense of independence．

Every American family has its own traditions on Thanksgiving Day, and mine is no difference. Once the national holiday arrives, my mom rises early to make the meal. She puts a turkey in the oven, chops carrots and bakes pies. I’m sorry to say that the men in the family – my dad, my younger brother and myself – rarely pitch in to help. Our job is to wash the mountain of dirty dishes after the meal is over.
Around 2 pm every Thanksgiving Day, family members seat themselves around the kitchen table. Plates of turkey, vegetables, salad, rolls and pies cover it. At this point, we can hardly keep ourselves from drooling (流口水) all over our fancy clothes, but it’s not yet time to eat.
First, we must bow our heads, close our eyes and say a prayer of thanks aloud to God for giving us everything we have. Under normal circumstances, I would have no problem making a list of things I am thankful for. I grew up in a loving family. My parents, who aren’t wealthy, took out loans to help me pay for university.
But, the funny thing is, every time I sit down for Thanksgiving dinner and try to say a prayer of thanks, my mind usually goes blank. I think it has something to do with my growling (咕咕叫) stomach and all of that food sitting right there under my nose.
Eventually, though, we all finish our short prayers and dig in. To be sure, the day includes other highlights – visiting with family and watching football. But usually around 6 pm we are all ourselves stuffed like turkeys and thankful to have a nice warm bed to sleep in.
小題1:The purpose of the text is to ________.
A．tell what the family do for Thanksgiving Day
B．tell how the family spends Thanksgiving Day
C．introduce foods served on Thanksgiving Day
D．introduce the American Thanksgiving Day
小題2:On Thanksgiving Day the author’s family do the following except ________.
A．watching a movieB．making visits
C．having a big mealD．watching football
小題3:Why does the author’s mind usually “go blank” when saying a prayer of thanks?
A．He is too thankful to say a word.B．His mind is on the food before him.
C．He feels too excited to speak.D．He is shy to speak in public.
小題4:The underlined phrase “dig in” in the last paragraph is closest in meaning to “________”.
A．chat with othersB．make a hole
C．mix things upD．start eating

One year ago, I traveled 15,000 kilometers from Australia to the US. I am from a beachside town in the   16  of Sydney, and thought there would be almost no   17  differences between my home country and my 18  . I was surprised at how wrong I was, and at  19  different the two countries could be.
The United States is   20  in almost every aspect. The buildings are gigantic (巨大的) and so are the people who   21  and work in them. At mealtimes, the portions (份額) often   22  to me to be big enough for three or four people. I once   23  a baked potato which turned out to be bigger than my head! This was a big   24  for me.

Despite this, certain stereotypes about places did seem to   32  true for me. There is an immense (強烈的) sense of speed in New York.

Are you a media addict who would go mad after two hours without TV, friend requests, exciting online games and your mobile – or would you easily survive?
Recently, university students around the world were asked to volunteer in a global experiment called Unplugged. It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours.
Unplugged is being run by Dr Roman Gerodimos, a lecturer in Communication and Journalism at Bournemouth University. The experiment is now over but he doesn’t yet know the full findings. However, during the experiment, Dr Gerodimos said there were already signs of how much the exercise affected volunteers. He said: “They’re reporting withdrawal symptoms(癥狀), overeating, feeling nervous, isolated and disconnected.” During their 24-hour painful experience, three of the experiment’s guinea pigs had to endure one intrusion(侵擾) from the media: a BBC reporter plus cameraman who followed them around for the day. They were asked to write down 100 lines about their day offline, but of course, they all waited until the next day when they had access to their laptops. Elliot Day wrote: “Today, my whole morning routine was thrown up into the air. Despite being aware of the social importance of the media, I was surprised by how empty my life felt without the radio or newspapers.” From Caroline Scott, we read: “I didn’t expect it, but being prevented from the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual… I didn’t break out in a cold sweat like our lecturer expected us all to, but it’s not something I would like to do again!” And Charlotte Gay wrote: “I have to say the most difficult item for me to be without has been my mobile; not only is it a social tool, it’s my main access point of communication.”
Earlier in the year, a UK government study found that in the UK we spend about half our waking hours using the media, often plugged into several things at once. And a recent study by Nielson found that on average, US teenagers send and receive over 3,000 texts per month ---that’s about six texts per waking hour. So, with technology continuing to develop at an alarming rate, how much time will you set aside for sleep in the future?
小題1:What’s the purpose of the first paragraph?
A．To ask for information.B．To entertain the readers.
C．To lead to the topic.D．To present an idea.
小題2:About Dr. Roman Gerodimos’ experiment, we know that ________.
A．volunteers felt uncomfortable in it.
B．volunteers didn’t want to eat anything.
C．the experiment was still going on.
D．volunteers were allowed to take their laptops.
小題3:Which of the following is true according to the passage?
A．Three pigs were included in the experiment.
B．A BBC reporter discussed the experiment.
C．During the 24 hours’ experiment the volunteers wrote out their experiences.
D．The lecturer had expected sweat would suddenly appear on the volunteers through fear.
小題4:What does the sentence “…was thrown up into the air” most probably means?
A．went on normally.B．was completely disturbed.
C．turned out perfect.D．was badly designed.
小題5:Which of the following can best serve as the title of the passage?
A．Surviving without the Media.B．Unplugging Your Life.
C．Valuing Social Communication.D．Setting Aside Time for Sleep.

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to schools, shops and anywhere else. Therefore, China is known as “the kingdom of bicycles”. In China, many families have one or two bicycles.
Compared with cars, bicycles have many advantages. First, they are much cheaper than cars. Most Chinese can’t afford cars, but they can afford bicycles. Second, bicycles are small enough to park anywhere, while cars need a larger piece of land to park. What’s more, with lower speed, bicycles are safer than cars.
However, bicycles also bring some problems. Some riders don’t obey the traffic rules and some riders don’t think about others safety. So they ride too fast. During the rush hour, too many bicycles may cause traffic accidents. We still have a long way to solve the problem.
