Relax. He is the same little boy you loved yesterday. I smiled trying to hold back the tears. “No, he isn’t. Yesterday I dreamed he would be an astronaut. Today I am hoping he will learn to talk.”
It was like some sort of cosmic joke. I could still recall the day that determined my fate. It was October in Ottawa and the summer breezes had given way to the autumn rainfall of leaves. The snow would begin soon. The crispness (清爽) of coming frost was in the air. My casually mentioning Wyatt’s behavior to Dr. Martin aroused his worries. He started asking me questions about Wyatt’s activities speech pattern and emotions. I still see clearly in my mind the cleanness of the room and all its belongings when the doctor turned to me and said, “He almost sounds autistic (自閉) .”
I couldn’t face that picture in my mind. I had to run to get away from this all too painful place that was reminding me of what was to be my child’s life-being strange.
I could not remember how many times I told myself, “This is normal. He is a little boy who is not talking yet,” when my asking questions met with his blank-eyed response in a restaurant; how many times I would tell myself, “He loves to play on his own for hours at a time and he never gets into trouble,” when Wyatt was playing games that no one else could imagine, let alone join in while other boys in the park were playing together or in small groups played around a sand pail(桶) or toy truck. My life was changing direction. So was Wyatt’s.
I started to hide Wyatt from my friends and neighbor especially from a good friend. It was too painful to let others know about my boy acting strange.
It was a Thursday afternoon and I found one half of a great pair of kitchen scissors was missing. They were unbelievably sharp and could be taken apart so they could be washed or the blades (刀片) sharpened. I knew Wyatt had taken the missing blade.
“Wyatt,” I began as patiently as I could, “Do you see this?” I held up the blade. “Do you know what this is?”
Wyatt put a bunch of Fruit Loops in his mouth. No response.
“Wyatt!” I forced eye contact with him. “Where are the other scissors? See these.” I showed him the half pair.
He smiled big. Ate Fruit Loops. Turned the TV on and off. Still no response.
I didn’t know what to do. It was really hard. “Wyatt,” I tried once more, “Mommy wants these scissors. Can you go get them for Mommy? It will make Mommy so happy if you bring me the scissors.”
“Watch Spongebob.” Wyatt asked as he slid down from his kitchen stool and ran off, leaving me shaking my head and wondering in exactly which way this situation was going to end badly.
Five minutes later, I turned my head to see Wyatt coming downstairs, his favorite doll in one hand, the missing half pair of kitchen scissors in the other. I immediately ran over and took it from him.
“Wyatt!” I hugged him. “Thank you for bringing me the scissors! Good job! You did it! These scissors need to stay in the kitchen. These are Mommy’s scissors!”
Wyatt laughed, looked at me straight in the eye and said, “Mommy so happy!”
I came close to tears. A realization dawned on me that he was the best gift I had ever gotten even though he was not as normal as other children. And why did I hide him from others as if he were some dark and terrible secret. No! He was my pride. It was a long, hard battle to get him to this point, expressing his wants and needs without turning to violence in embarrassment. With love and patience I have found the beautiful, happy boy who would teach me more about life.
And that is the solution.

(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)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

Imagine you’re in a dark room, running your fingers over a smooth surface in search of a single dot the size of this period, How high do you think the dot must be for your finger to feel it?
Scientists have determined that the human finger is so sensitive it can detect a surface bump just one micron(l0-6m)"high. The human eye, by contrast, can't tell anything much smaller than100 microns.No wonder we rely on touch rather than eyesight when faced with a new roll of toilet paper.
Biologically, touch is the mother of all sensory(感覺的) systems.It is an ancient sense in evolution: even the simplest single-celled living things can feel when something brushes up against them and will respond by moving closer or pulling away. It is the first sense aroused during a baby’s development and the last to weaken at life's peak. Patients in a deep coma (昏迷)who seem otherwise lost to the world will show skin reaction when touched by a nurse.
“Touch ,is so central to what we are that we almost cannot imagine ourselves without it,” said Chris Dijkerman.“It's 'not like eyesight, where you close your eyes and you don't see anything. You can't do that with touch.It's always there."
Long ignored in favor of the sensory heavyweights of eyesight and hearing, the study of touch lately:: has been gaining new concern among scientists.They're exploring the effects of recently reported false touch impressions, of people being made to feel as though they had three arms, for example, with the hope of gaining the true understanding of how the mind works.
Others are turning to touch for more practical purposes: to build better touch screen instruments and robot hands, a more well-rounded virtual life.。“There's a fair amount of research into new ways of offloading information onto our sense of touch," said Lynette Jones. "To have your cell phone buzzing (making a low sound) as opposed to ringing turned out to have a lot of advantages in.some situations."
Touch is our most active sense, our means of seizing the world and experiencing it 'first hand. Dr.Susan Lederman pointed out that while we can become aware of something by seeing or hear,ing7;-.from a distance and without really trying, if we want to learn about something by means of touch, we must make a move.We must rub the cloth, or pet the cat. Touching is a two-way street, and that's not true for seeing or hearing. If you have a soft object and you squeeze it, you change its shape. The physical world reacts back."
Our hands are smart and can do many tasks automatically - button a shirt, fit a key in a lock, play the; piano for others.Dr.Lederman and her colleagues have shown that blindfolded subjects can easily recognize a wide range of common -objects placed.in their hands.But on some feeling tasks, touch is all thumbs (very clumsy). When people are given a raised line drawing of a common object, they're puzzled.“If all we've got is outline information;" Dr.Lederman said,.“no weight, no texture, no temperature information, well, we're very, very bad with that."
Touch also turns out to be easy to fool, Among the sensory tricks now being investigated is something called the Pinocchio illusion. Researchers have found that if they shake the band of the biceps(二頭肌), many people report feeling that their forearm is getting 'longer, their hand floating ever further from their elbow(肘). And if they are told to touch the forefinger of the shaken arm to the tip of their nose, they feel as though their nose was lengthening, too. 
小題1:Which of the following statements is true according to the passage?   
A.Our eyes are more sensitive than our fingers.
B.Our fingers are more sensitive than our eyes.
C.Our eyes are more sensitive than our ears.
D.Our noses are less sensitive than our ears.
小題2:The sense that is firstly awaked during a child's development is the sense of        
A.sightB.tasteC.hearingD.touch
小題3:The underlined sentence “You can't do that with touch” here means “You can't        ”.
A.close your skinB.close your eyes ' C.touch anythingD.see anything

A.living a well-rounded virtual life
B.understanding how the mind works
C.favoring eyesight and hearing

Most parents and teachers would get angry when they hear that teenagers listen to their iPods while preparing for exams. But pupils who listen to music when doing their homework may be, in fact, working hard.
Thirty three schools have downloaded specially written pop and rock songs for their 10,000 pupils who are studying for GCSE (初級畢業(yè)證書). The professionally recorded music, based on texts in English literature, teaches teenagers about themes in the GCSE curriculum (課程). Two young men set up “Revise”, the company that produced the songs, and worked with teachers to make sure the lyrics (歌詞) reflected the curriculum. Some of the songs were written by Geraint Brown, a director, and they are performed by professional singers and musicians.
Songs for the GCSE science and maths lessons are also being developed in 36 schools. They have also started using the program, called, “LearnThruMusic”.
Dave Matthews, the head of Hawthorn High School in the South Wales valleys, said the program aimed at helping teenagers who are unwilling to study. He said, “There are lots of pupils who don’t have a high level of home support. It’s almost cool to say you have no need to find a support and we have got to change that. With this, they don’t have to be sitting at their desk at home. They can be outside, walking around or even listening to it on the bus, which is very convenient for them.” Everyone has a phone, MP3 or CD player, and they’re more likely to listen to these than pick up a book. “I think everyone would agree that music had an important influence on us when growing up. Both boys and girls are very good at remembering the words and dancing to the music in the charts. There’s no one thing that will successfully engage (使…產(chǎn)生興趣) every child, and some of them will make little or no use of this. But the fact that they don’t have to do any extra work makes this a very good deal for a kid,” Dave Matthews added.
小題1:The pop and rock songs used in 36 schools ________.
A.were written for the students to relax themselves
B.made most parents and teachers angry
C.were specially written for hardworking students
D.were closely related to the curriculum
小題2:Which benefit of the program is NOT mentioned in the passage?
A.It saves students much extra work.
B.It offers different ways of learning.
C.It makes remembering easier.
D.It improves family support to kids.
小題3:Which of the following can be inferred in the passage?
A.The program is not expected to have equal effect on every student.
B.Some students used the song as an excuse for not reading textbooks.
C.It’s more difficult to create songs for science and maths lessons.
D.Students involved in the program needn’t go to school every day.
小題4:Which of the following might be the best title for the passage?
A.Special-written Songs — A Reason Why Students Should Listen to IPods.
B.Special-written Songs — A New Way to Learn the Curriculum.
C.Special-written Songs — A Substitution for Textbooks.
D.Special-written Songs — Mothers’ New Concern.

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.

A smart phone (智能手機) is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation (導航) units to form one multi-use device. Many modern smart phones also include touchscreens and web browsers (瀏覽器) that display web pages.
A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn’t mean making calls, but playing phone games and browsing the Web.
Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It’s no secret that our lives are being affected by our smart phones obsession.
However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen.
Ironically, YouTube’s data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones.
The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it.
小題1:People prefer a smart phone to a common one, because the latter only can help us ______.
A.check emailsB.send messagesC.find the destinationD.watch a video
小題2:The underlined word “obsession” in the third paragraph most probably means “______”.
A.devotionB.contribution C.a(chǎn)ddictionD.emotion
小題3:Which of the following is right?
A.People spend as average of two hours and 40 minutes each day using smart phones.
B.The film hasn’t been put on in the cinema.
C.The film is written by an actor named Charlene Deguzman.
D.The film has already been viewed more than 105 million times in the first few days.
小題4:When the writer mentions the number of people watching the film from mobile devices in the fifth paragraph, he mainly feels ______.
A.encouraged B.depressedC.proudD.satisfied

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

Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment. Animals become endangered for a variety of reasons.
Some animals become endangered when their habitats contain resources for humans. For example, commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups. Land itself is an important resource to humans since it provides us with living space, and when people replace animal habitats with human habitats, it can lead to larger loss of natural species.
Commercial and industrial operations may reduce land or water for animals and pollute their environment. Due to water pollution, the baiji, a fresh water dolphin native to China, was declared extinct, meaning it’s unlikely the population can recover. Even noise pollution from human activities can lead to the disorder of animal behavior.
Another cause that makes animals become endangered is over-fishing or over-hunting. Over-hunting whales led to near extinction of many species of whales.
The introduction of a non-native species to a habitat may make animals become endangered. The native species may not defend against a new one, and the effects can be dangerous. In Australia, the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals.
Introduced species can also bring new diseases with them. As a result, animals become endangered. Native animals may not have the power to fight against non-native diseases, and population levels can suffer. Another cause of disease is human-introduced chemicals. The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction.
When animals become endangered, the entire food chain can be affected. For example, in 2008 disease seriously harmed the honeybee, which is largely responsible for pollinating(授花粉)  plants, including many fruits and vegetables. Without their pollination, a very large part of the human diet could be reduced. In fact, if the honeybee should become extinct, our life would be affected and billions of dollars would be lost. Therefore, many people argue that when animals become endangered it is in man’s own self-interest to protect them.
小題1:The passage is mainly about ______.
A.ways of protecting animals’ habitats
B.effects caused by species endangerment
C.dangers of bringing in non-native species
D.reasons why animals become endangered
小題2:Which of the following examples shows that environmental pollution may cause species endangerment?
A.The extinction of the whales.
B.The extinction of the red-fronted parakeet.
C.The decreasing population of the dolphin.
D.The effect of the honeybee on the human diet.
小題3:Why is it dangerous to introduce a non-native species to a habitat?
A.Native species are likely to die from the new diseases.
B.It’s hard for non-native species to survive.
C.Non-native species will take up more space.
D.Native species are so powerful for non-native species.
小題4:The California Condor is in danger of dying out because of ______.
A.loss of habitatB.harmful chemicals
C.forest cuttingD.unfamiliar diseases
小題5:We can infer from the last paragraph that ______.
A.humans are to blame for species extinction
B.small animals mean little to the whole food chain
C.protection of the honeybee has cost billions of dollars
D.humans protect animals for the benefit of themselves
