阅读理解      A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through
the year and the temperature rarely dipping below 16℃. Rainforests have a great effect on the world
environment because they can take in heat from the sun and adjust the climate.
     Without the forest cover, these areas would reflect more heat into the atmosphere, warming the rest
of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing
certain natural disasters all over the world.
     In the past hundred years, humans have begun destroying rainforests in search of three major
resources (资源):land forcrops, wood for paper and other products ,land for raising farm animals. This
action affects the environment as a whole. For example, a lot of carbon dioxide (二氧化碳) in the air
comes from burning the rainforests. People obviously have a need for the resources we gain from cutting
trees but we will suffer much more than we will benefit.
    There are two main reasons for this. Firstly, when people cut down trees , generally they can only use
the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of
wood right now,but in the long run it actually reduces the world"s wood supply.
     Rainforests are often called the world"s drug store. More than 25% of the medicines we use today
come from plants in rainforests. However, fewer than l% of rainforest plants have been examined for
their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the
world"s shrinking rainforests.1. Rainforests can help to adjust the climate because they_________.  A.reflect more heat into the atmosphere
B. bring about high rainfall throughout the world
C. rarely cause the temperature to drop lower than 16℃
D. reduce the effect of heat from the sun on the earth2. What  does  the  word "this" underlined in the third paragraph refer to?   A. We will lose much more than we can gain.
B. Humans have begun destroying rainforests.
C. People have a strong desire for resources.
D. Much carbon dioxide comes from buming rainforests.3. It can be inferred from the text that____________.   A. we can get enough resources without rainforests
B. there is great medicine potential in rainforests
C. we will grow fewer kinds of crops in the gained land
D. the level of annual rainfall affects wind patterns4. What might be the best title for the text?  A. How to Save Rainforests
B. How to Protect Nature
C. Rainforests and the Environment
D. Rainforests and Medical Development

      Gadgets (小装置) can be wildly expensive and quickly out-of-date, but Steven Poole is still the
first to buy them. Technological innovations (创新) are often quite stupid. The idea that you might
want to walk down the street holding a mobile phone in front of your face, just to experience the
wonders of video calling, is clearly ridiculous. Luckily for the tech companies, however, there are
some people who jump at the chance to buy into new gadgets before they are fully ready and cheap
enough for the mass-market. They are called early adopters, and their fate is a terrible one. I should
know, since I am one myself.
      Early adopters have a Mecca: it’s Tokyo’s Akihabara district, also known as “Electric City”.
There, in 1999, I bought a digital camera, a gizmo that few people in Britain had heard of. Over the
next few years I watched in great sadness as digital cameras became more popular, cheaper and more
powerful, until better models could be had for a quarter of the price I had paid. Did I feel stupid? What
I actually did was this: I splashed out more money last year for a new one, one that let me feel pleasantly
ahead of the curve once again. But I know that cannot last, and I’ll probably have to buy another in a
few years.
      Thus early adopters are betting on other people eventually feeling the same desires. And it’s worse
if that future never arrives. Early adopters of the Betamax home-video format in the 1970s could only
look on in sadness when their investment was nullified（使无效）by the success of VHS. All sorts of
apparently splendid inventions, such as videogame consoles like the Atari Jaguar have been abandoned
to the dustbin of history right after a few early adopters bought in. Those who invested thousands in a
Segway motorized scooter on the wave of ridiculous advertising campaigns that accompanied its launch
a couple of years ago can join the club.
      You might think we should just stop being so silly, save our money, and wait to see what really
catches on. But the logic of the industry is such that, if everyone did that, no innovation would become
popular. Imagine the third person to buy an ordinary telephone soon after Alexander Graham Bell had
invented it. Who was he going to call? Maybe he simply bought two phones, one for a special friend.
But still, the usefulness and eventual popularity of the device wasn’t clear at the time. Nobody dreamed
of the possibility of being able to speak to any one of millions of people. And yet if he, and the hundreds
and thousands of early adopters after him, had not bought into the idea, the vast communication networks
that we all take for granted today would never have been built.
     The same goes, indeed, for all new technologies. Those guys holding bricks to their ears that we
laughed at in the 1980s made the current mobile phone possible. People who bought DVD players
when they still cost a fortune, instead of today’s cheap one at the local supermarket, made sure that
the new format succeeded. Early adopters’ desire for desires supported the future financially. And
what did they get for their pains? They got a hole in their bank accounts and inferior, unperfected
technology. But still, they got it first. And today they are still at work, buying overpriced digital radios,
DVD recorders and LCD televisions, and even 3G phones, so that you will be eventually be able to
buy better and less expensive ones.
      So next time you see a gadget-festooned geek (满身新潮玩意的土包子) and feel tempted to
sneer (讥笑), think for a minute. Without early adopters, there would be no cheap mobile phones or
DVD players; there would be no telephone or television either. We are the tragic, unsung foot soldiers
of the technology revolution. We’re the desire-addicted pioneers, pure in heart, dreaming of a better
future. We make expensive mistakes so you don’t have to. Really, we are heroes.

     Every kid more or less complains about school. But five to ten percent of kids dislike it so much that
they don"t want to attend. lf a child seems upset or anxious about school, pretends to be sick to stay
home, repeatedly winds up in the nurse"s or principal"s office, or refuses to talk about the school day,
you should be concerned.
     One fear that keeps children from enjoying school is separation anxiety. It most frequently occurs
during times of family problems or when a child is about to enter a new school. With younger kids, watch
how you say good-bye those first few days of school. A firm "Have a great day, and I"ll pick you up at
2: 30!" is more confidence-inspiring than" Don"t worry. I can be there in ten minutes if you need me. "
     You can help your child handle fearful situations-from speaking up in class to taking tests-by
rehearsing at home. Help make large projects less discouraging by breaking them into manageable
pieces. Teach your child to replace thoughts such as "I"m going  to  fail" with" I can  handle this".
     Some kids dislike school because they have no friends. This may be the case if your child is always
alone, fakes illness to avoid class outings or gives away treasured possessions in an attempt to be liked.
Often loneliness problems can be solved by improving social skills. A child may need to learn how yo
look others in the eye when he speaks, or how to talk above a whisper -or below a yell. You might
teach a young child a few "friendship openers", such as "Myname"s Tom. What"s yours? Do you want to
play games?"1. When a school boy has separation anxiety, he is___________ .A. worried about his study
B. uncertain if he can deal with his family
C. eager to go to school
D. unwilling to leave his family for school2. Which of the following is NOT a fearful situation for a new school kid?A. Making a public speech.
B. Taking an examination.
C. Finishing a lot of housework.
D. Doing a big amount of homework.3. When a child gives his beloved toy to an unfamiliar classmate, he must be stuck in___________.A. separation anxiety
B. complaints about school
C. a loneliness problem
D. a fearful situation4. Which of the following best shows the composition of the passage ?
   ( l)-Paragraph 1
    (2)-Paragraph 2
    (3)-Paragraph 3
    (4)-Paragraph 4A. (1)→(2)→(3)→(4)
B. (1)(2)→(3)(4)
      ↗ (2)         ↗ (1)

阅读理解     Even facts " forgotten" by people during a busy day may beretrieved if this is followed by a good
night"s sleep. Researchers from the University of Chicago asked volunteers to remember simple words.
Many found their memories letting them down towards the end of the day, but the following morning,
those who had slept well could recall much more. Reserchers , writing in  the journal  Nature .said  the
brain  coud  " rescue"lost memories during the night.When the brain is first asked to remember something
that memory is laid  down  in  an " unstable " state, meaning that it is possible that it could be lost. At
some point, the brain consolidates those it deems important into a "stable" , more permanent state.
     However, the Chicago researchers suggested that it was possible for a " stable" memory to be made "
unstable" agan.This would  mean  that memories could be modified then filed away again in the face of
new experiences.
The 12 volunteers tested in the experiment were played words created through a speech synthesizer
which were purposely difficult to understand. Initially, the written version of the word was available,but
after wards the volunteers were asked to identify the word from the audio version only. Tests revealed
that the ability to recall the right word tended to tail off as the day ended.
     However,when the volunteers were retested after a good night"s sleep,they were able to recall some
words that they had"forgotten" the previous evening. Dr Daniel, one of the study authors, said : " Sleep
consolidates memories , protecting them against subsequent interference or decay. Sleep also appears
to "recover" or restore  memories. " He said : " If performance is reduced by decay , sleep might actively
recover what has been lost. "
     Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: " Memory
research is undergoing a transformation-no longer is memory thought to be a hard-wiring of" the brain ,
instead it seems to be a process of storage and restorage. "
     Sleep helps some memories " mature" and also prunes out unimportant memories..1. What does the first paragraph implies?

A. A busy day makes people forget things easily.
B. People need a good night"s sleep after a busy day.
C. A good night"s sleep helps memories.
D. A good night"s sleep helps people forget a busy day.

2. The words the 12 volunteers played in the experiment were not_________.A. created through a speech synthesizer
B. hard to understand
C. available at the beginning
D. designed to test people"s ability of understanding3. According to the passage , memory _________.A. is a hard-wiring of the brain
B. is not a process of storage
C. is not a process of restorage
D. will be mature with the help of sleep4. Which of the following is NOT true?A. When people first remember something, the memory is in an" unstable state " .
B. The brain will change those important unstable memories into stable.
C. Once the memory become stable, it will never become unstable again.
D. Sleep can protect memories from being harmed

Toucans(巨嘴鸟), a kind of tropical birds known for its colorful beak, are very smart. In Mexico, my dad became friends with a toucan that was in a "walk in and see the birds" cage. The toucan was so smart that it knew how to get out. It just needed some human to help it. It almost flew out while we were leaving! I also noticed that all toucans have different beaks! They also have very long unique beaks with an extremely long tongue. It struts(大摇大摆地走) around with its chest sticking out and beak pointed forward. The toucan is a beautiful bird! The beak has a red tip (different shades on every one), but sometimes there is a little turquoise on the bottom half. Then, right where the beak separates there is a splotch of yellow. And the rest of the beak is green. The toucan takes very much pride of itself. The toucan eats fruit and seeds. The ramphastidae(the toucan family) is known for its long beak, and 37 species. Toucans also feed on insects, small lizards, bird nestlings and eggs. They nest in hollow trees where they incubate and care for their young.They are found in the woody areas. Of the various toucan facts, here is an odd one. Citizens of Central and South America associate the toucans with evil spirits. They think the birds can be the personification of evils. Where couvades(父代母育) is practiced, the father of a new child must not eat toucan flesh as it is believed to bewitch the new-born child. Yet the toucan can also be a tribal totem(图腾). So the medicine men use it as a symbol to fly to the spirit world. 1.Which of the following words is NOT suitable to describe toucans? A. Intelligent B. Confident C. Dangerous D. Colorful 2.The second paragraph mainly talks about _______. A. where toucans strut around B. how toucans get food C. what toucans look like D. when toucans lay eggs 3.What does the underlined word"incubate"probably mean in paragraph 3? A. Hatch eggs B. Take cover C .Gather strength D. Keep warm 4. We can learn from the last paragraph that _______. A. all citizens of Central and South America are afraid of toucans B. the toucans can also be used as medicine to cure diseases C. a new child must not eat toucan flesh because it is poisonous D. some people believe toucans can bring them misfortune
