In nature, you may see many insects and animals of different colors. Have you ever wondered why?
Locusts （蝗蟲）are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies（敵人）. The reason is that the colors of locusts change with the colors of crops （莊稼）. When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.
Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies （蝴蝶）and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.
Have you ever noticed some even stranger acts（行為）? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.
小題1:According to the passage, most soil insects ______
A．do not have bright colors
B．change their colors with the soil
C．do not live in a dark and wet environment.
D．eat colorful insects like butterflies and bees.
小題2:What’s the meaning of the underlined word “survive” in the passage?
A．繁殖B．產(chǎn)卵C．覓食D．生存

The smallest animal with a backbone（脊椎） known to science, a fish from the carp family, has been discovered in the peat swamps （沼澤）of Indonesia. Mature（成熟的）females of the fish species （種類）Paedocypris reach just 7.9mm in length.
The species was discovered in the highly acidic (酸性的) peat swamps of the Indonesian island of Sumatra by a team led by Ralf Britz, a zoologist at the Natural History Museum in London.
“This is one of the strangest fish that I’ve seen in my whole career,” Dr Britz said. “It’s tiny, and it lives in acid. I hope that we’ll have time to find out more about them before their habitat disappears completely.”
The species lives in dark tea-colored swamp waters, which are 100 times more acidic than rainwater. Although these swamps were once thought to be inhabited by very few animals, recent research has shown that they are home to a highly different range of species that occur nowhere else.
The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture. The scientists behind the discovery said that several populations of Paedocypris had already been lost.
“Many of the peat swamps we surveyed（調(diào)查）throughout South-East Asia no longer exist,” Dr Britz said. “Populations of all the miniature（微型的）fish of peat swamps have decreased or disappeared.”
Details of the discovery are published today in the journal Proceedings of the Royal Society of London, Series B.
小題1:64.Which of the following would be the best title for the passage?
A．The Strangest Fish
B．Acidic Peat Swamps
C．Strange Species
D．The Smallest Backbone Animal
小題2:65.Where does the smallest backbone animal live?
A．It lives in highly acidic rainwater.
B．The species lives in the acidic waters of dark tea-coloured swamps.
C．It was put in the Natural History Museum in London.
D．Its habitat disappears completely.
小題3:66.According to the passage, the forest fires in 1997 have led to the fact that______.
A．many places where these animals lived have been damaged
B．the population of the specieshas increased
C．there are many animals in the acidic peat swamps today
D．a(chǎn)griculture doesn’t affect the living space of these animals
小題4:67.Dr Britz’s words imply______.
A．the habitat will be more after a period of time
B．many peat swamps that they surveyed have already survived
C．he wants to find more miniature fishes before their habitat disappears
D．he wants to have further research

If your idea of a good time is to sleep in a hut, carry your own rubbish, and eat insects and wild animals, then ecotourism may be just for you. But is it also for people who want to fly over a rainforest sky before checking into a comfortable and expensive hotel in the middle of a national park? Whatever ecotourism is, it is hot--perhaps too hot for its own good.
The World Tourism Organization claims that the industry looked after 592 million travelers last year who spent $423 billion, and of all the types of tourism, ecotourism seems to be the fastest growing. By the broadest measure -- a trip with some sort of nature or wilderness element -- ecotourism already accounts for perhaps a third of these travelers. On a stricter definition favored by the Ecotourism Society, it is “responsible travel that preserves natural environments and keeps up the well-being of local people,” which accounts for no more than 5% of tourism.
Ideally, ecotourism helps both people and nature. Before the disastrous civil war, Rwanda’s Mountain Gorilla Project was one such model. Visits to the gorillas were limited, local guides ensured good behavior or on the part of the humans, and the high admission charge - $170 a day -- paid for salaries and presentation of the gorillas’ living areas. As this made the gorillas worth more alive than dead, poaching (偷獵) decreased. As another example, preservation Cooperation, Africa’s largest ecotour operator, uses only local labor, buys products 5om local farmers, and supports building projects: such as clinics and schools. This contribution to social advance is also good business sense. Projects from which local people benefit directly are less likely to be affected by poaching and theft.
Ecotourism’s biggest problem is labeling. Going on an eco-tour is no guarantee of good ecology. So far, only Australia has an official system to grade tour operators and tourist attractions on the basis of their “greenness”. Another issue is how eco-tourists damage the environment. Dolphin-feeding, for instance, is innocent and enjoyable, but after too many free meals, the dolphins forget how to catch their own dinners.
Keeping prices high is one way to limit enthusiasm. But measuring the effect of ecotourism on human environments is trickier. It is common, for villagers to see ecotourism as a source of new income. Hence, the very tourists who venture in search of traditional cultures end up breaking them up. As ecotourism becomes more popular, it will finally threaten the very things that are good for business.
小題1:According to the passage, ecotourism may _________.
A．harm its own purpose by becoming too popular
B．save the environment by becoming more popular
C．harm its own purpose by becoming less popular
D．save the environment by becoming less popular
小題2:Within the tourism industry as a whole, ecotourism _____________.
A．has no single, clear definition that would satisfy everybody
B．has expanded less rapidly than other types of tourism
C．claims that no comfortable hotels should be used by tourists
D．most often has a negative effect on local culture
小題3:Rwanda’s Mountain Gorilla Project is a good example because ___________.
A．tourists were free to visit the gorillas whenever they wanted to
B．local people’s attitudes toward animals were not affected
C．the gorillas were protected from both tourists and local people
D．the gorillas’ living area was modernized because of the high admission
小題4: _________ most directly benefits the local community.
A．Rwanda’s Mountain Gorilla ProjectB．Preservation Corporation
C．Australia’s grading systemD．Dolphin-feeding

Scientists Alan M．Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology(毒物學(xué))testing．Improvements in cell and tissue culture technologies，for example，allow a growing number of tests to be performed on human cells alone．Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals．
Since the late 1990s，Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration—has become a proving ground for aggressive strategies by animal-rights militants （好戰(zhàn)分子）．At a hearing，a Senate．committee listened to testimony（證詞） against Huntingdon employees and financial institutions providing services to the company．One experimentation witness at the hearing insisted that any means necessary were justified（辯護(hù)） to spare animals’ lives；he has previously accepted the idea of murder to that end．
Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically（倫理道德地）preferable to experimenting on humans or giving up cures that could save human lives．But for the sake of people and animals alike，the development and acceptance of animal substitutes deserve enthusiastic support．
In some instances, substitutes are already thought as good or better than animals，but supervising agencies（監(jiān)督機(jī)構(gòu)）have yet to catch up．In both the European Union and the U．S．，scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals．Thus，animal-loving Americans might turn to persuading the EPA and the FDA to speed validation（確認(rèn)）of new methods so that they can be more widely employed．And animal advocates（保護(hù)者） who want to influence business could consider investing in the small biotech’s and large pharmaceutical（藥品的） companies that are working to develop alternatives to animals in research．
小題1:_____ plays a leading role in replacing the use of animals in testing．
A．Huntingdon Life SciencesB．Improvement in technologies
C．Animal-fights militantsD．Scientists Alan and Thomas
小題2:Accordingly, the animal-rights militants hold the view that_____．
A．a(chǎn)nimals shouldn’t be used in toxicology testing
B．a(chǎn)nimals should enjoy equal rights with human beings
C．a(chǎn)nimals should live wildly and freely
D．we should protect animals from being killed casually
小題3:From the passage，we can find _____．
A．the use of animals in testing has been stopped abruptly
B．a(chǎn)nimal substitutes are not preferable
C．supervising standards contribute to the continued use of animals in testing
D．only Huntingdon Life Sciences is accused
小題4:What’s the main idea of the passage?
A．Saving animals and people．
B．The new trend in toxicology testing
C．The use of animals in testing is against human nature
D．New technology changes the fate of animals
小題5:The writer’s attitude towards replacing the use of animals in toxicology is____．
A．a(chǎn)rbitrary（武斷的，隨意的）B．pessimistic
C．indifferent（不關(guān)心的 ）D．optimistic

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino （厄爾尼諾）. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韋）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication（出版物）Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
小題1:El Nino is known as ___.
A．the changing of the weather in southern Africa
B．the warming of waters in the Pacific Ocean
C．the weather which brings drought（旱災(zāi)）to Africa
D．the weather phenomenon（現(xiàn)象）that brings heavy rains to Africa
小題2:Scientists study El Nino in order that ___.
A．they can provide a kind of early warning to the place that will suffer from drought
B．they can tell why Zimbabwe has little or no rain
C．they can do some research work in this field.
D．they can put all this information into their computers.
小題3:Which of the following is TRUE according to the passage?
A．Scientists come to understand how El Nino appears.
B．Three scientists from the USA work on this subject.
C．Southern Africa suffered a serious drought and many people died from hunger.
D．El Nino has something to do with Zimbabwe’s poor crops.
小題4:Which of the following is NOT true according to the article?
A．The computer is used in this research work.
B．Scientists know when an El Nino appears by means of the computer program.
C．The scientists published their results of the research work.
D．Nature is the name of the article written recently by the scientists.
小題5:What’s the best title for this passage?
A．Appearance of El Nino is Predictable（可預(yù)測(cè)的）
B．Drought in Zimbabwe
C．Early Warning System
D．Weather in Africa

As soon as I saw her, I understood I was in trouble. The tiny 10-year-old girl was staring at me with that specific facial expression which probably only dentists have to enjoy all day long!
Whatever question I asked, whatever activity I suggested, her reaction was pretty much the same — she was frozen with horror. She was sent to our private language school after having been the worst in English at her key school with a pretty strict ELT syllabus(教學(xué)大綱), with her peers teasing her for her mistakes in English. Moreover, her state school teacher called her name. To make things worse, she was under pressure from her family for getting bad marks in English. She was definitely expecting me to carry on the same way with her.
I have to admit that I had been staring at her with probably the same expression for a while before eventually she handed in an absolutely incredible composition which I had previously asked the class to write. It was written in perfect handwriting, was full of clever ideas and had correct paragraphing. The girl got her first excellent mark in English, and I praised her generously and from then on I started using her writing skills to support the others. Before doing an oral retelling of a story, she wrote it down. Before presenting her oral project, she was allowed to do the same thing. The day she first put up her hand to orally answer my question addressed to the class I was incredibly happy.
She taught me how to approach withdrawn students — find the skill which they can excel at, in her case writing, and help the student use it to develop other skills!
小題1:The writer is probably a teacher 　　　. 
A．in a language training center
B．in a private language school
C．in a state school
D．in a key public school
小題2:The writer’s first impression of the little girl was that she was 　　　. 
A．incredibly dullB．hard to cope with
C．far too lovelyD．pretty confident
小題3:The girl came to the school because 　　　. 
A．she had some special skills
B．she was good at writing poems
C．she felt very uncomfortable at her previous school
D．she is poor at her pronunciation

How to Study Smarter, Not Harder
Here are some of our favorite study tips that will help any student study smarter, not harder:
Recite As You Study
Reciting—saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding.
Take Fuller Notes
Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.
Study the Middle
The best time to review is soon after you’ve learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.
Sleep On It
Study before going to bed, unless you are very tired. It’s easier to remember material you’ve just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you’ve fallen asleep.
Combine Memory and Understanding
There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding.
The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again.
小題1: You can notice your mistakes by _______.
A．saying things out aloudB．taking notes
C．studying the middleD．sleeping on it
小題2:When taking notes, you should _______ to better help you with reading.
A．underline important notes
B．write notes in your own words
C．take down every detail
D．write as quickly as possible
小題3:The writer advises you to _______ as it is easier for you to remember material.
A．study after a period of activity
B．do some exercise after studying
C．study as soon as you get up
D．study before going to sleep
小題4:Which of the following is NOT helpful for your understanding?
A．Thinking about an idea in different ways.
B．Relating ideas and concepts with what you already know.
C．Reading from the beginning to the end without stop.
D．Going back to what first made you confused and start again.

Beautiful cars surrounded by even more beautiful models—it’s no secret why the 2012 Beijing Auto Show was popular．
The exhibition was held between April 23 and May 2．Although renowned companies showed off their top models，it wasn’t just their expensive sports cars that grabbed people’s attention．
Concept cars are a way for designers to test out their ideas on the public with complete freedom．They can try out cars with special features that could not be massively（批量）produced easily．
Designers don’t have to follow industry rules；they don’t even need to worry about whether their cars would be followed on the roads．
At the Beijing Auto Show，the@Ant by Chery was one concept car to draw a lot of attention．China Daily called it‘‘the very definition of a concept car”．
The vehicle is powered by electricity and is capable of driving itself．But the magic doesn’t end there．
The@Ant was inspired by actual ants．According to Car News China，with the help of automated telemetric systems，@Ants are able to“see” other@Ants and compare  destination information. If two are heading the same way for a while, the vehicles connect, with one car’s rear (后面的)wheels matching up with the front wheels of another car．Up to 10@Ants can be put together and will automatically connect to form a“train"．This  will help save energy while traveling, as well reducing traffic jams.
The car sounds like a great idea．Further research will be needed to turn this concept  car into something for the market，but concepts like Cherry’s  show how carmakers are  working for cleaner and greener vehicles．It’s like what the@Ant motto says，“Exploring future human beings’lifestyles”．

Another day begins with the call of the phone’s alarm, Where are you? Open your eyes. Turn the alarm off and you will start working out on your apps（應(yīng)用軟件）.
First stop, weather: Sunny day. Look outside the window. Oh, no, it isn’t. Second stop, Air Quality Index: 344, dangerous, Level 6 Severely Polluted. Mental recheck required: It really is a sunny day and the weather app isn’t lying or in need of being replaced, it’s just that you can’t see the sun through the thick fog. Note to self: Cycling to work is out, face mask is in.
Has the world stopped turning? News app merely confirms that it’s business as usual. Another government has fallen, your soccer team has lost again, and China’s economy is still increasing steadily.
Diary app informs you of all the things you failed to do the previous day and loads you up with another half-dozen tasks. Next, browse a couple of social networking apps to determine the status updates of friends.
Another sound from the phone, it’s a message from your significant friend who is already at work, saying the Taobao. com order for Italian cheese is about to arrive.
Apps have become part of our “every-moment” lives. Apps provide so much information. But the dark side to all this connectivity would be lack of privacy, being a slave to the app. The only real problem is that once you lose your smartphone, you lose your life.
Some friends and family do not have smartphones, but prefer the old-fashioned Nokia that merely makes phone calls and sends instant messages. While I respect their purity and desire to be free of the control of technology, it’s obvious they are outsiders, and their lives are loaded up with paper and old devices. They’re still buying books at stores, complaining the lack of CDs on the market, watching TV and missing out on complete news cycles. Though I would add, they have lives that aren’t spent inside small screens.
My phone is a palm-sized one-stop shop and about the only thing it doesn’t do is teleport（心靈運(yùn)輸）. What’s not to like?
小題1:The functions of apps mentioned in the passage can be listed as follows EXCEPT that _______.
A．the apps can show you weather forecast
B．the apps can tell you how to work directly
C．the apps can inform you the latest news
D．the apps can tell you what you failed to do
小題2: According to the passage, the author thinks that _______.
A．people’s life is governed by apps
B．people feel bored about the use of apps
C．people can’t live without apps
D．people hate apps with powerful functions
小題3:It can be inferred from the last paragraph but one that _______.
A．more and more people like Nokia more than apps
B．using Nokia can be free of the control of technology
C．a(chǎn)ll people don’t like the advanced smartphones
D．ordinary people don’t like shopping online
