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（调查）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.

When you speak in your native language, you don"t have to think about the grammar or the words you use. Correct sentences just come to you. In fact, your brain uses sentences you"ve already seen or heard. If you want to speak a foreign language fluently, you have to learn it the way you learned your native language--- by massive(大量的) input.
Reading and listening will help you develop language intuition(直觉). It"s all about putting lots of correct sentences in your head. Then your brain can imitate them, producing similar sentences to express the meaning you want. When you read and listen a lot, paying attention to useful vocabulary, you will soon start to use new words and phrases in your speaking and writing, and you will develop language intuition. You will start to feel what sounds good and what sounds bad --- just as you do in your native language.
It may seem like you need more time to learn a language by reading and listening, as opposed （相反的）to learning based on grammar rules. For example, to get a good feeling for the use of articles in English you need to read lots of sentences, analyzing them closely. Wouldn"t it be easier to read a unit on articles in a grammar book? Well, the problem is that it takes lots of time to build a sentence when you have to think of grammar rules. When you talk to someone, you don"t have time for that. The input-based approach may seem to be more demanding, but it"s the only way to achieve fluency.
小题1:According to the passage, if you want to speak a foreign language like a native speaker, you must_________.
| A．learn grammar very well |
| B．input many sentences in your head |
| C．read many books in the foreign language |
| D．write many compositions |
| A．Ability to understand a foreign language |
| B．Ability to use a foreign language without thinking about it |
| C．Ability to speak a foreign language |
| D．Ability to imitate a native speaker |
| A．Listening and Reading |
| B．Writing and Listening |
| C．Reading and Translating |
| D．Listening and Translating |
| A．You can speak your native language without think about grammar |
| B．Before you can speak your native you must hear millions of sentences |
| C．The input-based approach is the only way to speak a language fluently |
| D．Grammar is no use at all |
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 fllowed 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 Chery’s show how carmakers are working for cleaner and greener vehicles．It’s like what the@Ant motto says，“Exploring future human beings’lifestyles”．
小题1:The concept car is getting popular because .
| A．it looks like an ant |
| B．it is beautifully designed |
| C．it is exhibited as a top model |
| D．it conveys a new idea for the future |
| A．By connecting each other and running together． |
| B．By driving themselves without man’s control． |
| C．By comparing their destination information． |
| D．By reducing traffic jams on the roads． |
| A．to test the safety of the concept car |
| B．to follow the rules in the car industry |
| C．to show their unique idea of complete freedom |
| D．to see if concept cars can be massively produced |
| A．Concept Cars Are Driving to the Future |
| B．The@Ant Draws a Lot of Attention |
| C．The@Ant Is a Top Model of Concept Cars |
| D．Concept Cars Are Cleaner and Greener |
John Marrit, a psychologist(心理学家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who operates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, he says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the person’s movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the safe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.
小题1:The new kind of machine being introduced in the passage is _______.
| A．in existence | B．only an idea |
| C．being tried out | D．being researched and developed |
| A．follows the person’s order |
| B．is controlled by a computer |
| C．does exactly what the person does |
| D．is controlled by a television on the person’s head |
| A．the new machine is more difficult to make than a robot |
| B．the new machine is more difficult to be controlled |
| C．a robot is controlled by man indirectly |
| D．a robot can’t be used in places too dangerous or faraway |
Thanks to special bacteria in the stomachs，kangaroo flatulence（肠胃气胀）contains no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep which produce large quantities of the harmful gas．
While the usual image of greenhouse gas pollution is a huge factory chimney pushing out carbon dioxide，farm animals’ passing wind contributes to a surprisingly high percentage of total emission（排放物）in some countries．
“Fourteen percent of emissions from all sources in Australia is from methane from cattle and sheep，’’said Athol Klieve，a senior research scientist with the Queensland state government．
“And if you look at another country such as New Zealand，which has got a much higher agricultural base，they are actually up around 50 percent，”he said．
Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers．
But it will take researchers at least three years to isolate the bacteria before they can even start to develop a way of transferring it to cattle and sheep．
Another group of scientists，meanwhile，has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos．And about twenty percent of health-conscious Australians are believed to eat the national symbol already．
“It’s low in fat，it’s got high protein levels and it’s very clean in the sense that basically it’s the free-range（放养的）animal，”said Peter Ampt of the University of New South Wales’s institute of environmental studies．
小题1:The passage mainly talks about ________.
| A．a better way to prevent air pollution |
| B．the danger of methane from farm animals |
| C．possible solutions to protecting environment |
| D．a recent research on global warming |
| A．prevent them from sending out harmful gases |
| B．promote Australian farming |
| C．protect Australian ecosystem |
| D．make the most of the special bacteria |
| A．to reduce the number of animals raised on farms |
| B．to eat more kangaroos rather than keep more sheep and cattle |
| C．to eat more plants rather than beef and mutton |
| D．to grow more trees to absorb carbon dioxide |
| A．it is easy to transfer the bacteria to cattle and sheep |
| B．farm animals are to blame for global warming in some countries |
| C．cattle and sheep produce more methane than kangaroos |
| D．less cattle and sheep are raised in New Zealand |
The 16-year old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute,
has discovered a way to make plastic bags degrade(分解) in as few as 3 months, a finding that won him first prize at the Canada－Wide Science Fair, a $10 000 prize, a $20 000 scholarship, and a chance to revolutionize a major environmental issue.
Burd"s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he ground plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” said Daniel Burd.
小题1:Daniel Burd won first prize at the Canada－Wide Science Fair because________.
| A．he found a new kind of microorganism |
| B．he contributed much to environmental protection |
| C．he found a way to degrade plastics in shorter time |
| D．he could encourage microbes growth in an easier way |
| A．make the live bacteria work better |
| B．test how effective his method was |
| C．know which bacteria worked faster |
| D．control the temperature in the process |
| A．plastics can get hot easily |
| B．microbes can produce heat themselves |
| C．much carbon dioxide is produced |
| D．the temperature can be controlled |
| A．his school textbook | B．the failure of researchers |
| C．his everyday work | D．the practice of other people |
