      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(挨打) 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 allows the robot to            .

A、do housework for humans B、keep working after being damaged C、remember a lot of information D、tell people where it is
(3)、The underline word “them” in Paragraph 5 refers to          .

A、sensors B、robots C、arms and legs D、scientists
(4)、How do the sensors in the robot work?

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

    I am a professor of sports and exercise so I often deal with nervousness in my research with sports people. Actually, most people experience nervousness at some time or another.
    If you are feeling anxious, my advice is to first find the cause or causes. Make s list of those things that are making you nervous and work out which ones you can do something about. Focus all of your efforts on managing the causes that you can control.
    Most people cannot tell the difference between controllable(可控制的) and uncontrollable causes, so things they can't control become a big reason for nervousness. Dealing with this is very important if people want to keep a healthy mind.
    Simply try to accept the uncontrollable causes of nervousness. You might be worried about the weather on a big day, an accident or an attack on the train, or perhaps just things that other people are doing at work. The results may be very important but there is still no use worrying because you can't control any of these things. Accept that you can't control everything. Once you understand this, it becomes easier not to worry.
    If a situation, such as swimming, is causing you to be anxious, try to face it as often as possible so that you can get used to it.
    It can often help to think about yourself doing the thing that make s you nervous—then close your eyes and imagine it going well. Imagine how the flight or job interview is going to happen so that you can get used to it. This will help you understand that the thing you fear most is probably not going to happen.

    Do you look like your name? Scientists say there's a good chance you do.

This comes from a new study published in a magazine. Researchers from Israel found that our given names may have something to do with our facial (面部的) appearances.

    Lead writer Yonat Zwebner of a university, along with her team, did eight different experiments (实验) in Israel and France. The different experiments were set up to answer two main questions: whether people can correctly guess a person's name based only on a photo of a face and what is behind this matching effect.

    During the experiments, researchers asked students to look at photos of people's faces and guess each person's name from a list of four choices. They correctly guessed the right name 38 percent of the time, which was better than the 25 percent of a random (随机的) guess.

    What's more, when the faces the students looked at came from within their own country, they were able to best match the faces to the names. French students were better at matching only French names and faces while Israeli students were better at matching only Hebrew names and Israeli faces.

    Researchers believe it is possible that people change their appearances without paying attention to it, to match their names. One study especially backed up this idea, showing that a hairstyle, something that can be changed by people easily, was enough to guide others in correctly guessing their names.

    “Earlier research has shown there are cultural stereotypes (偏见) carried by names, including how someone should look. For example, people are more likely to imagine a person named Bob to have a rounder face than a person named Tim. We believe these stereotypes can, over time, influence people's facial appearances,” Zwebner said.

    The results of the experiments may even make parents think twice when choosing a name for their children.

    “If a name can influence appearance, it can influence many other things. This research opens an important direction that may suggest how parents should consider better the names for their children,” said Zwebner, who recently had a baby herself.

    “As parents, it was really difficult for us to name our 12-day-old daughter as we know the meanings of names.”

    The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers.However, there is another difference between humans and computers.Computers don't forget information they are given, but humans often do.No one remembers everything, and luckily we don't usually have to.But everyone can improve their memory if they want to.Here are some suggestions.

    Try to use new information immediately.For example, if you meet someone who says "Hi! I'm Carlos."Don't just say "Hello." Repeat the person's name.Say "________"

    Break a big number into smaller parts. For example, it's hard to memorize (记忆) 109244153.But if you break it into three parts  109/244/153--it becomes easier.

    Write out what you need to remember over and over again.This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.

Always review information.If you bring what you've learned back to your mind, it becomes easier to remember. For example, before you go to sleep, it's a good idea to review the new things you learned that day.

    Discuss with a friend.It is always easier to remember things through discussions.You can have a discussion about what's right and what's wrong, and it will lead to the right answer.

    Never tell yourself that you have a bad memory.You can always do something to help improve your memory.And everyone's memory gets better if they use it often enough.

    All the suggestions are helpful.If you follow them, you are certain to improve your memory.

    Developing healthy eating habits starts from childhood, therefore it is important for parents to teach and provide children with a healthy diet.

    DPHSS administrator of the Bureau of Nutrition Services, Charlie Morris said, "A healthy diet for a child always includes a lot of fruits and vegetables in the diet limiting the amount of simple sugars in the diet and high fat food and highly processed* food." This means staying away as much as possible from food such as chips, cookies, candies and sugary drinks, because all children need to have meals and the meals should be a well-balanced diet.

    Community nutritionist* Thelma Romoso said, "The fruit, the vegetable, the grain, the protein, and also the milk, the diary product are all necessary in the diet for a child. Among them, the fruit and the vegetable should come first. It's easy for a mother to go into the two plus three concept* of fruits and vegetables or five a day." This concept means that there are at least two servings* of fruits a day, three servings of vegetables a day which can be served for lunch and dinner.

    Morris also said that the child's hunger level influences how much is eaten and the parent controls what and when the meal is offered, saying, "Mom needs to make sure that the food offered is good food for the child to eat and she also needs to consider how active they are through the day. Snacks* are not a bad thing, so the mom should offer good kinds of snacks as well."

    When it comes to preparing your child's lunch and snacks for school, make sure to keep in mind that the food you provide should not only provide enough energy but also be healthy such as fresh fruits, and whole grain bread. But parents must be sure to remember that a good healthy diet must be balanced with physical activity, that is to say, it is important that children get outside and run around and play and get activity besides eating a good diet.
