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．

The spider (蜘蛛) is very little and clever. Its body is made up of two parts. It has four pairs of legs and eight little eyes.

The spider loves work. It begins to work as soon as it begins to live. Every spider is a weaver. Even the youngest spider knows how to weave (编织) its web (网) just as well as the oldest.

The silk of which it makes its web comes from its body. It is like hairs. Many of these hairs come out at the same time, but they are all formed into one rope of silk. It is so thin that a hundred of them together are only as thick as a human hair.

First the spider fasten (固定) one end of the silk thread (丝线) to a leaf or to a piece of wood, then it turns and fastens it to the other end.

When the spider fastens both ends, it can run down the silk and fix some more threads. These are the cross ropes of the web. Then it weaves other lines round them, and makes about twenty rings.

Then spider works hard and fast, and it finishes its work in less than an hour. The web is then so strong that the wind cannot blow it away and the rain cannot break it. The purpose (目的) of the spider’s web is to catch insects (昆虫), which are its food.

Insects cannot walk or fly out of the web, because the spider covers it all with something like glue (胶水), which sticks to (粘) anything that touches the web and holds it fast (牢固).

Not all the spiders are the same sort of work to do.

Some spiders are masons(泥瓦匠). They build houses the size of a big thimble (顶针). They make doors in them, which they shut after them when they go in. They can even fasten the door of the house from the inside, so that no robber can get in.

The garden spider lets thread float in the air till they stick to plants or to the branches of trees. It then uses these threads as the roads or bridges to cross from one place to another.
