These seem to be the most important basic needs in their lives. However, it39。s far from enough. We have to e up with better ideas. A man called Nicholas Negroponte invented a cheap laptop puter, which he decided to invent after he visited a school in Cambodia. The laptop which Mr. Negroponte has designed is not the same as the normal one that you can buy in the shops. One difference is that it will be covered in rubber so that it is strong and won39。t be damaged easily. As an electricity supply can be a problem in developing countries, the puter also has a special handle in order that children can wind the puter up to give it extra power when needed. This special laptop puter will cost less than 100 US dollars and Mr. Negroponte wants to produce as many as 15 million laptop puters in the first year. The idea is that these puters will help the children39。s education as they will be able to access the Internet. These puters might not benefit the people in developing countries immediately, but by improving children39。s education they should help people to find their own solutions to their problems in the long term. Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK. And probably in many other countries too, millions of mobile phones are thrown away every year. The waste crested by throwing away thee old phones is very bed for the environment, so it seems to be an excellent idea to achieve two important goals at the same time. We will reduce the waste we produce and help others. In other words, we will be able to kill two birds with one and that is always a good thing. （1）The underlined phrase wind up in paragraph 2 means .
