    In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
    Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
    Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged (毁坏). That is because its computer inside simply doesn't know how to make the machine work after its shape has changed.
    To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals to the machine's software. Using this information, the computer can then figure out the machine's shape at any moment.
    The new technology is a big advance in robot-making, scientists say, and it's far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
    “It has been difficult to design robots that can work well when the environment changes or when it's damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”

（1）、Why do robots easily break down when they are damaged?

A、They cannot repair themselves. B、The computer has changed a lot. C、They have no computers inside D、The computer cannot work if the robot changes.

（2）、The new technology(技术) allows the robot to .

A、keep working after being damaged B、tell people where it is C、do house work for humans D、remember a lot of information

（3）、The underlined word “them” in Paragraph 5 refers to .

A、sensors B、robots C、scientists D、arms and legs

（4）、How do the sensors in the robot work?

A、They can replace the computer when it's broken. B、They help the computer learn the robot's condition. C、They can find out where the damage comes from. D、They can send signals to the person who uses the robot.

    When we talk of plants, most of us will think of things that grow from the ground and have green leaves, but there are plants that do not look or act like other plants. Some of these belong to a special class of plants called fungi.
    Fungi may appear almost everywhere. They commonly grow in wet places where they call get food and water easily. Because fungi do not have green leaves to make their own food, but fungi must take their food from animals, other plants or water. Some fungi live on dead or rotting（腐烂的）wood, while others grow on living trees or in dirt or moss（苔藓）. Mushrooms（蘑茹）are the best-known fungi.
    There are many kinds of mushrooms appearing in all shapes and sizes. For example, cauliflower（菜花）mushrooms are found in forests from July to October．They can grow to be as heavy as fifty pounds! They grow at the foot of trees Squirrel's（松鼠）bread is another kind of wild mushroom Its appearance and use Call explain its name. These fungi look like small golden cakes Squirrels can easily eat them or carry them off to their hole to eat later.
    The mushrooms found in food stores are carefully grown by people who know they are safe to eat. People are warned never to touch of taste wild mushrooms because some of them are deadly. Even less dangerous ones cart still make a person very sick..

Indian scientists have designed a new device that they hope will solve one of the biggest problems with the use of solar energy. They call the device a solar tree. Solar trees have metal “branches” which are just from a tall pole at different levels. Each branch holds a solar panel*. These panels have large metal boards that collect energy from the sun and turn it into electricity.

Daljit Singh Bedi is the main scientist at the Council of Scientific and Industrial Research in India. Bedi says the shape of the solar trees makes it possible to fit more solar panels in a space than traditional systems do. This means less land would be needed to produce solar energy. “It takes about four square meters of space to produce energy which may need 400 square meters of space,” he says.

Scientists believe the energy a solar tree collects will be enough to power five homes. The solar tree will make it easier to provide solar energy for homes in cities. The trees will also take less space from farmers in rural areas. Bedi says solar trees will collect more energy than normal solar panels on the tops of buildings. “This design makes the solar panels exposed more towards the sun,” he says. “And that way people are able to use 10 to 15 percent more energy.”

India has promised to reduce its greenhouse gas production. The country's promise depends heavily on increasing solar energy. The cost of solar panels has gone down in recent years. This has increased the possibility of applying solar trees in India.

Amit Kumar is the senior director of the Energy and Resources Institute in New Delhi. He says gaining access to land takes time and increases costs. He adds that it is still not clear how useful these new developments in solar power technology are. “Only when we put those trees on a large scale will we be able to get that answer,” he says.

Food waste is common in many schools. Students at Whitewater Middle School in the US once found 200 pounds (90. 7kg) of food had been thrown away after just one of their school's daily meals. They said it was both unpleasant and educational.

A student said, "You don't realize how much food waste you're making till you see it. " To deal with this problem, Whitewater has added environmental science as a new school program this year. Teachers will lead students to do research about how food connects with the environment, poverty (贫穷) and people's health.

Whitewater teachers make sure students know how their own eating habits are part of bigger problems. In environmental literature (文学) classes, students read books such as Fast Food Nation: The Dark Side of the All-American Meal.

Teacher Lyman says that in language arts classes, students discuss why poor people often have less healthy food. Lyman says she wants students to ask themselves some basic questions: "What do we eat? What do we waste?
