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”．

| 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 |

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 |
A polar bear"s dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July．
The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals．"From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it． However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone．"
Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals． That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April．
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change．
The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．
小题1:How did Stirling know the reason for the death of the polar bear?
| A．By the food he ate． | B．By doing further experiments． |
| C．By observing other polar bears． | D．By his lying position in death． |
| A．easily hurt | B．difficult to hunt |
| C．dangerous | D．amazing |
| A．Favorable． | B．Uncaring． |
| C．Doubtful． | D．Concerned． |
| A．A novel． | B．A guidebook． |
| C．A news report． | D．An advertisement． |
1. Protect wildlife habitat.
Perhaps the greatest threat that faces many species is the widespread destruction of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare species live, habitat destruction can quickly force a species to extinction. By protecting habitat, entire communities of animals can be protected together naturally. Parks and reserves are now all too often the only habitats that are left untouched by habitat destruction.
2. Reduce the threat of invasive (入侵的) species.
The spread of non-native species has greatly reduced native populations around the world. Invasive species compete with native species for resources (资源) and habitat. They can even prey on native species directly, forcing native species towards extinction.
3. Place decals (贴花纸) on windows.
It is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.
4. Slow down when driving.
Many native animals have to live in developed areas and this means they must move in human-living areas. One of the biggest obstacles (障碍) to them is that created by roads. Roads divide habitat and present a constant risk to any animal attempting to cross from one side to the other. So when you’re out and about, slow down and keep an eye out for wildlife.
小题1: What would be the best title for this passage?
| A．How animals go to extinction |
| B．The importance of protecting wildlife |
| C．What to do to help save wildlife |
| D．How to protect wildlife habitat |
| A．more parks and reserves should be built |
| B．we should have more habitats free of destruction |
| C．there is a need for improvement in parks and re-serves |
| D．parks and reserves are good examples of protecting wildlife |
| A．decorate the houses and beautify the environment |
| B．protect the windows from birds hitting |
| C．attract more birds to make homes nearby |
| D．avoid birds hitting the windows by mistake |
| A．drive away | B．live with | C．kill for food | D．fight with |
