For better eyesight, doctors advise limiting the hours of screen time and encourage having enough eye resting time.
However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia（近視）. An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.
The research team found that the prevalence（流行）of myopia among children in Sydney was lower than children in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore.
Indoor and outdoor sports activities both make the eyes focus on more distant objects, which prevents the eyes from changing shape. But outdoor activities may better help avoid myopia than indoor sports activities.
Jane Gwiazda, who does research in sight problems, says: “Natural light is good for eye growth. And extra vitamin D from the sun might contribute to eye growth.”
Many doctors suggest that every child get its first eye test done when he/she is about two and half years old, and even if his/her sight seems perfect.
It is necessary for myopic children to wear glasses to prevent headaches, trouble reading or injuries. It is also important that schools invite doctors to test their students’ eyes.
If that is not possible, school teachers should at least encourage parents and children to have regular eye examinations and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors.
小題1:What’s the aim of the study by the Australian research team ?
A．To find the reasons for myopia.
B．To find the ways to treat myopia.
C．To prove the bad effects of myopia.
D．To prove the prevalence of myopia.
小題2:Why are there fewer children with myopia in Sydney than in Singapore ?
A．Because Sydney children watch less TV.
B．Because Sydney children have more eye resting time.
C．Because Sydney children use computers less.
D．Because Sydney children do more outdoor sports.
小題3:What conclusion can we draw from the passage ?
A．Sydney children don’t study hard.
B．Singapore children do few exercises.
C．Outdoor activities do more good to eyes.
D．Room light does harm to children’s eyes.
小題4:Which of the following statements is TRUE ?
A．Children should have eye tests as soon as they reach school age.
B．Doing outdoor activities with no glasses is good for myopia children.
C．Focusing on distant objects can help the eyes keep their original shape.

Why texting harms your IQ
The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.
It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.
Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 per cent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.
The effects on IQ were studied by Dr Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”
小題1:We can learn from the passage that “infomania” ______.
A．has a positive influence on one’s IQ
B．results in the change of part of the brain
C．lies in the problem of lack of concentration
D．is caused by too much use of modern technology

[1] What do you do to take care of the books in your library? Some collectors(收藏者) refuse to read the books in their collection; so the books remain in good condition. Others buy two copies of a book: they read one, and leave the other untouched. However, many readers must read their books, but they still want to protect and care for the volumes. Here are some tips to remember if you want your books to remain in good condition.
[2] Avoid Writing. You may have been told to write in your books, or even to underline words, phrases, and paragraphs. But if you plan to keep the book, add it to your library, or even sell it — don't write in the book. The ink may damage your book forever. Use a notebook to take notes or use pieces of paper. If you are required to write in your book, use a pencil, and remove the markings later.
[3] Avoid Food and Drinks. Food and drinks are things that may be dangerous to your books, so the best way is to avoid eating or drinking while you read. If you need to read while you eat, make sure your fingers are clean and dry as you hold the book or turn the pages. Also, keep the book well away from the food and drinks.
[4] Take Care. When you handle your book, hold it with care. When you read the book, don't fold down the corners of the pages (use a bookmark instead). Don't place your book with the book open, face-down. You'd better use a book cover to keep your book in the best condition.

New findings suggest that brainy card games such as contract bridge may temporarily(臨時(shí)地) raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune(免疫) cells, according to the research reported last week.
A researcher, Diamond, studied bridge players from a women’s bridge club. She chose bridge players because the game includes skills stimulating(刺激) a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system.
The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland(胸腺) and used by the immune system against diseases.
The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology(神經(jīng)免疫學(xué)), whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated(獨(dú)立的) systems. What isn’t clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses.
小題1:Playing bridge can help one to fight off diseases because it can _______.
A．raise production of a key blood cell B．make people joyful
C．a(chǎn)id digestionD．make break away from the bad habits
小題2:Diamond chose to study bridge players for the research because _______.
A．the players are good friends of hers
B．she loves playing bridge
C．this game stimulates a part of the brain that has something to do with immune system
D．she is a clever manager, who operates her bridge club well
小題3:A T cell is _______ cell.
A．a(chǎn) brainB．a(chǎn) white blood
C．a(chǎn) red blood D．a(chǎn) kind of dangerous blood
小題4:Which of the following is true according to this article?
A．The immune system and the brain system used to be considered separate and isolated systems.
B．The help to the immune system that is brought about by playing bridge can last for a long time.
C．Cortex is a kind of blood cell.
D．The new findings are impossible.

People who are hit by lightning and survive often have long-term effects. These may include memory loss, sleep disorders, muscle pain and depression(郁悶).
Experts tell people to seek(尋找) the safety of a building or a hard-top vehicle any time they hear thunder, even if it is not raining. They say lightning can strike as far as sixteen kilometers from any rainfall. Lightning can travel sideways. And at least ten percent of lightning happens without any clouds overhead that you can see.
People who are outdoors should make sure they are not the tallest thing around. Bend(屈身) low to the ground, but do not lie down. And do not stand near a tree or any tall object. Get away from water and anything made of metal. A car is safe, but do not touch any metal inside.
Safety experts say people in buildings should stay away from anything with wires or pipes that lead to the outside. The National Weather Service says if you plan to disconnect any electronic equipment, do so before the storm arrives. Do not use a wired telephone. Do not use water. All these can carry electricity.
Some people think a person struck by lightning carries an electrical charge （電荷） afterward. Experts say this is not true. It is safe to begin emergency treatment.
Each year about four hundred people in the United States are struck by lightning. Last year forty four people died. The average(平均) is close to seventy. The National Weather Service says that is more than the number of people killed by severe storms.

What is your favorite color? Do you like yellow, orange, and red? If you do, you must be an optimist(樂觀者), a leader, an active person who enjoys life, people and excitement. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference(愛好), and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing(壓抑). Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.
Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.
小題1:According to this passage,           .
A．one can choose his color preference　　
B．one is born with his color preference
C．one’s color preference is changeable

Howling(吼叫) is a behavior commonly observed among a wolf pack(狼群). As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There’re 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 behavior.
Indeed, there have been times when wolves have been seen one moment howling in a chorus(合唱), 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 (地位) among its members? Why do wolves howl for sure?
What is clear, however, is that howling is often used among pack mates 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 behavior. 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
小題1:What is the possible similarity between wolves’ howling together and human’s 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 hunting 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 onesD．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
