Eyesight problems are common among all ages and if they are left untreated, they can cause serious headaches or other problems. The good news is that most eyesight problems can easily be sorted out by wearing glasses.
Regular eye tests are important for everyone. Children and teenagers, under the age of 16 and up to the age of 19 for those full-time education, have the right to have eye tests for free in Britain. As the eye test is free, there’s no excuse for not having a regular eye test. Doctors suggest that it’s better to have an eye test about once a year.
Wearing glasses isn’t always regarded as all that cool and teens who suddenly need to wear glasses may find it difficult to accept. If they’ve grown up wearing glasses, then they may be more used to it. However, if your eyes are in poor health, not wearing glasses can put even more pressure on your eyes and could make them even worse.
Thankfully, the days of little choice of glasses frames (框架) for teenagers are gone and there’s now a wide selection of frames. If a teen does need to wear glasses, then it’s good to let him or her choose the type, as he or she will be able to choose something he or she feels comfortable. Don’t forget to be guided by the experts on glasses too.
小題1: According to the text, teens in the UK ______.
A．have few eyesight problems
B．can design their own glasses
C．change their glasses very often
D．can check their eyes without paying
小題2:How often do doctors suggest teens to have an eye test?
A．Once a month.B．Once every six months.

Here is an astonishing and significant fact：Mental work alone can’t make us tired.It sounds absurd.But a few years ago，scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲勞)．To the amazement of these scientists，they discovered that blood passing through the brain，when it is active，shows no fatigue at all! If we took a drop of blood from a day laborer，we would find it full of fatigue toxins(毒素) and fatigue products.But if we took blood from the brain of an Albert Einstein，it would show no fatigue toxins at the end of the day.
So far as the brain is concerned，it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning.The brain is totally tireless.So what makes us tired?
Some scientists declare that most of our fatigue comes from our mental and emotional(情感的) attitudes.One of England’s most outstanding scientists，J.A.Hadfield，says，“The greater part of the fatigue from which we suffer is of mental origin.In fact，fatigue of purely physical origin is rare.”Dr.Brill，a famous American scientist，goes even further.He declares，“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored，anger，anxiety，tenseness，worry，a feeling of not being appreciated－those are the emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.
小題1:What surprised the scientists a few years ago?
A．Fatigue toxins could hardly be found in a laborer’s blood.
B．Albert Einstein didn’t feel worn out after a day’s work.
C．The brain could work for many hours without fatigue.
D．A mental worker’s blood was filled with fatigue toxins.
小題2:According to the author，which of the following can make sitting workers tired?
A．Challenging mental work.
B．Unpleasant emotions.
C．Endless tasks.
D．Physical labor.
小題3:What’s the author’s attitude towards the scientists’ ideas?
A．He agrees with them.
B．He doubts them.
C．He argues against them.
D．He hesitates to accept them.
小題4:We can infer from the passage that in order to stay energetic，sitting workers need to ________.
A．have some good food
B．enjoy their work
C．exercise regularly
D．discover fatigue toxins

(2013·高考安徽卷，B)Using too much water or throwingrubbish into our rivers are clear ways that humans can put our water supply in danger，but we also affect our water supply in less obvious ways.You may wonder how paving(鋪砌) a road can lead to less useable fresh water.A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It comes from underground.The more roads and parking lots we pave，the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺)．Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall，but in any case，good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference，too.In the United States，a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there’s a lot we can do to lower the number.
You can take steps to save water in your home.To start with，use the same glass for your drinking water all day.Wash it only once a day.Run your dishwasher (洗碗機(jī))only when it is full.Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
小題1:Which of the following is most likely to lead to less groundwater?
A．Using river water.
B．Throwing batteries away.
C．Paving parking lots.
D．Throwing rubbish into lakes.
小題2:What can be inferred from the text?
A．All water shortages are due to human behavior.
B．It takes a lot of effort to meet our water needs.
C．There is much we can do to reduce family size.
D．The average family in America makes proper use of water.
小題3:The last paragraph is intended to________.
A．show us how to fix leaks at home
B．tell us how to run a dishwasher
C．prove what drinking glass is best for us
D．suggest what we do to save water at home
小題4:The text is mainly about________.
A．Why paving roads reduces our water
B．how much we depend on water to live
C．why droughts occur more in dry climates
D．how human activity affects our water supply

Cloud seeding is a method of artificially causing clouds to produce precipitation （降水） in the form of rain or snow．Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes．The effectiveness of cloud seeding remains controversial （有爭議的）．but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production．
Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War II．Their work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplane．In this form, the carbon dioxide is called dry ice．On November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground．
For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperatures．Their theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vapor．Their theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snow．As the snow reached the warmer temperatures closer to the ground, it melted and became rain．
Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide （碘化銀）．He used particles of silver iodide because its crystal structure resembled that of ice in clouds．Silver
iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature
and did not require an airplane as a delivery mechanism．Instead, silver iodide crystals could be fired by
cannons （大炮） high into the air, where wind carried them into the clouds．
小題1:According to the text, Langmuir and Schaefer had intended to deal with__
A．how to freeze carbon dioxide                      
B．how to remove ice on plane wings
C．how to make weather forecast for the war             
D how to hide planes in clouds at war
小題2:What is the CORRECT order of the course for cloud seeding with dry ice?
a．snow becoming rain in wanner temperatures             b．crystals attracting more water vapor
c．crystals falling in the form of snow                     d．crystals becoming very heavy
e．freezing tiny droplets of water vapor into crystals
f．putting small grains of dry ice in the cloud
A．a(chǎn)-c-f-d-b-eB．b-f-e-a-c-d
C．f-e-b-d-c-aD．e-a-d-c-b-f
小題3:Bernard chose silver iodide as a method of cloud seeding because___．
A．it is much cheaper than dry iceB．it can be stored at any rooms
C．it can be sent into clouds by windD．it is similar
小題4:The best title for the passage may be "____"．
A．Cloud Seeding
B．Artificial Raining
C．Weather Changing
D．Cloud Gathering
小題5:How many methods of cloud seeding are mentioned in the passage?
A．three B．twoC．oneD．four

Move Earth—It’s Not Science Fiction

LONDON—Scientists have found an unusual way to  prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets(彗星)in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA)engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun, ”Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so“seriously compromise” our biosphere(生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation(誤算)in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is“most likely the Moon would be stripped away from Earth”. This would greatly change our planet’s climate.
小題1:What makes the scientists plan to move Earth?
A．A few comets are moving to the direction of Earth.
B．Earth’s working life is coming to an end soon.
C．Earth will become too hot for mankind to keep alive.
D．The moon is moving farther and farther away from Earth.
小題2:If the plan is successful, Earth will have a working life of　　　years.
A．12 billion　B．6 billion
C．18 billion　D．24 billion
小題3:What serious problems might the plan cause according to the passage?
A．The comet might hit Earth and man might lose the Moon.
B．Earth might be moved too far away and man might be frozen to death.
C．The comet might hit Jupiter or Saturn and never return to Earth.
D．Earth’s working life might be greatly shortened.
小題4:What does the underlined word“compromise”mean?
A．Provide. B．Benefit.
C．Share. D．Endanger.

You have some great ideas. But they don’t come out because of what your friends say or because you think that only a few people can be creative geniuses(天才). And, you, of course, think that you couldn’t be one of them. But actually, this is not true at all.
Anyone who is a creative genius will tell you that creativity is very much like a muscle that needs to be developed. If you don’t learn how to develop creative thinking, this skill, just like a muscle, will become poor and useless. On the other hand, keep working at it, and this skill will soon be ready for action whenever you need it. So how do you develop your own personal style of creative thinking?
You should realize that your brain has a greater capacity (容量) and a higher speed than the world’s biggest and fastest computer. So it’s important to get as much information as you can every day. Read, watch and listen to everything around you —good and bad. The more you know, the more you’ll want to know, and the more your brain will be exercised.
Try something new every day and let your experiences show you more about the world and people around you. You need to step out of your comfort zone (舒適地帶) more and more each day.
Follow these suggestions, and begin thinking beyond your "limits" from today. You’ll soon have a life full of interesting and exciting adventures. Who knows, your idea might be the next great idea to change the world.
小題1:Most people can’t be creative geniuses because they _______.
A．don’t have great ideas
B．don’t want to develop their ideas
C．a(chǎn)re too shy to talk about their ideas
D．don’t believe they can be

American researchers found females are the more talkative sex because of a special “l(fā)anguage protein(蛋白質(zhì))” in the brain.
The study, conducted by neuroscientists (神經(jīng)學(xué)家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy. “Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals. “
小題1:From the second paragraph, we can learn that ________.
A．women always speak more words than men
B．men and male rats have low levels of language protein
C．women and male rats have similar levels of Foxp2
D．McCarthy isn’t the first to find females more talkative
小題2:The underlined phrase “fussed over” in the third paragraph probably means______.
A．paid attention toB．related toC．put pressure onD．counted on
小題3:The researchers carried out the experiments on rats in order to _______.
A．test which part of the brain is key to language in rats and humans
B．prove the levels of Foxp2 protein in humans and rats are different
C．determine the reason why female rats are more talkative than male rats
D．discover the association between Foxp2 protein and vocal communication
小題4:Which of the following can be the best title for the passage ?
A．Tests on humans and rats
B．Why women are the talkative sex
C．Sex differences in Foxp2 protein
D．Foxp2 protein determines oral ability

We are always told that TV is not good for us. If it is true, how come the TV-addicted kids of our young generation nowadays are much smarter than we are? In my family, the only persons who can work the TV remote control well are the children.
Probably TV really educates us. For example, we can learn a very useful medical fact: A man that has been shot always has time to speak a broken sentence when he is dying. “The killer was…” (dies)
But I suppose the biggest things that we learn from TV can be regarded as “Life Skills”. Bad things simply happen on either stormy or dark nights. Emotional breakdowns make people wander in the heavy rain without raincoats or umbrellas. And contrary to the scientists, the crack of lightning and the accompanying flash come on at exactly the same time, wherever the scenes are.
I’ve even got to know useful geographical facts from science-fiction shows: Aliens only speak the language of English no matter which planet they come from.
To make good use of something that we learn from TV can make our security better. Consider these truths. When you are really attacked by 20 bad guys, you needn’t worry about your being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
TV often teaches us a lot of important information as well about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
Be warned, however, if your name card says “henchman” (幫兇) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
小題1: When the writer says “A man that has been shot always has time to speak a broken sentence when he is dying” (Paragraph 2), he shows his________.
A．humorB．sympathyC．deep concernD．medical knowledge
小題2: We can learn from Paragraph 3 that in the real world________.
A．bad things cause people to break down in the rain
B．bad things never happen on dark and stormy nights
C．people with emotional problems like to walk in the rain without umbrellas
D．you can’t hear the crack of lightning and see the accompanying flash exactly at the same time
小題3: On TV what usually happens when a person turns it on?
A．The program shown is always about the importance of TV.
B．The person always turns off the TV when it’s time for news.
C．The news shown is always about someone the person knows.
D．TV always shows news about famous people.
小題4: What’s the main idea of this passage?
A．Life skills can be learned from TV.
B．What happens in TV is quite different from reality.
C．Watching TV makes people more creative.
D．TV plays an important role in society.
小題5: The writer of this passage takes a(n) ________ attitude towards TV plays.
A．positiveB．casualC．negativeD．indifferent
