    Robots in class

        Over 600,000 children in the United States spend their long time in hospital each year．Many of them say that they have difficult in returning to school after hospital stays．Thanks to technology，kids who are sick in the hospital no longer have to miss time in the classroom．

        A program called PEBBLES makes it possible for kids in hospital to take part in classroom discussions by using robot．PEBBLES(Providing Education by Bringing Environments to Students)supplies robots to help kids who are staying in hospital keep up with their classmates．

        For Achim Nurse，a 13-yers-old patient at Blythedale Children’s Hospital in Valhalla，New York，PEBBLES helped him so much．When he first learned about the program，he wasn’t so sure it would work．    

       “When I first saw it，it looked difficult，”said Achim．

        However，after 30 minutes of working with the robot，Achim discovered that he had gotten good at operating it．

        The robots work in pairs—一one in the hospital with the student，the other in the classroom．

        The robot in the classroom gives the student in the hospital a feel of“tele-presence．”A live picture of the students is shown on a video screen in the classroom．Meanwhile，in the hospital room，the student knows clear about what is going on in the classroom．

        The robot at the school has four wheels．so it can move around from class to class．Its“face” is an auto-focus(可以自动调焦的)camera．By using a control box，the student call turn the robot’s head，raise its hand，and adjust the volume(音量)．It is even equipped with a scanner(扫描器)and printer，so if the teacher want to have an exercise or testing class，the student can participate from the hospital．

       “The robot is greeted by students in the classroom．It is also greeted by the sick student。”said Andrew Summa，national director of the robot project．

    根据短文内容完成下面各题。

    1．Try to use the phrase underlined in the first paragraph to make a sentence．

    2．Guess the Chinese meaning of“keep up with”．

    3．The robot is greeted by students in the classroom．It is also greeted by the student in the hospital．(改写为同义句)

    4．According to the passage，we can know that____

      A．We can operate this kind of robot easily．   

      B．the student in hospital cannot adjust the volume by using control box．

      C．The teacher wants to have a test in the class now. Although the student in the hospital has this kind of robot，he also cannot participate it．

    5．What do you think of the robot project in the United States? Do you think it can help sick students? What do you think are its limitations?

    根据短文内容，判断正误。正确填(A)错误填(B)。
    What would the future life be like? I think we can travel faster and safer around the world and into space. Maybe one day we can work in Beijing, sleep in Chengdu and visit the moon for a holiday.
    We will have new energy(能源) that doesn’t make pollution. Possibly, people will find ways to use cleaner things, such as sea water, to make energy without polluting the earth.
    We will have machines that can copy everything in the future. Put a cake on the machine and it makes a new one. Of the machine is like a fax-machine, we can send food and presents to our friends easily.
    We will have clever robots that work for us, and the robots can bring us useful things and take away our trash. Now we have to press a key or type a word to make a machine work. But in the future, if we think of something, the machine can make it for us. The machine can understand our ideas.
    We can go into computer games and films, and everything will feel real. We can make our homes like forests or sunny beaches or anything we want. Maybe, one day we can collect our dreams and put our dreams on DVDs

    Have you ever seen people building houses? To build a house , you need workers. They use their hands , tools(工具) and machines to put things together. Building the ISS（国际太空站） is the same. The difference is that the workers are astronauts. They walk in space and use robots’ arms and hands to do their work.

    In the space station ,astronauts are comfortable. The temperature there is about 21℃.But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(阴暗处)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes----spacesuits.

    Spacesuits also keep astronauts safe from flying rubbish(垃圾)in space.Each time people go into space , they leave rubbish there. So astronauts should be careful because there’s a lot of rubbish, some rubbish goes many times as fast as a plane !

    Space walking is not easy , and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900man-hour of work.

    1.What’s the temperature in the space station?

    A. 21℃             B120℃              C. -85℃                D.-21℃

    2.The astronauts work in space with

    C.robots’ arms and hands                D.workers’ hands

    3.Which of following is TRUE according to the passage?

    A.Space walking is very comfortable                   

    B.Space walking is difficult

    C. Astronauts needn’t wear spacesuits when walking in space.

    D. Space walking is very safe

    4.What does the underlined word“spacesuit”mean in Chinese?

    A.太空服            B.防暴服                C.羽绒服                D.雨衣

    5.Which of following is not TRUE according to the passage?

    A.Spacesuits can keep astronauts warm

    How do you remember the way to your house? Where do dreams come from?
    It is your brain (大脑) that does these things. A British scientist showed that sleep can improve one’s memory. It’s not a dream for students to study when they sleep. In fact, your brain is working day and night. If you learn words before bed, a certain part of your brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(按钮)” in the human brain. It might make a person more talented(有才能的).
    There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning（打哈欠）keeps your brain “cool”, which makes us think quicker.
    Here are some pieces of advice to keep a good brain:
    ● Eat healthy food.
    ● Get a lot of playtime or exercise.
    ● Don’t drink or smoke.
    ● Use your brain a lot.
    【小题1】A British scientist found out that               .

    A．drinking could affect our memories.
    B．dreams could affect our memories.
    C．sleep could improve our memories.
    D．bananas could improve our memories.
    【小题2】According to the passage, if we want to have a good brain, we should  .
    A．use our brains more
    B．sleep fewer hours
    C．work longer hours
    D．remember fewer things
    【小题3】Which of the following is TRUE according to the passage?
    A．Our brains only work in the daytime.
    B．Our brains need much energy every day.
    C．Smoking can keep our brains healthy.
    D．Getting exercise is good for our brains.
