       Some young engineers from the United States have brought the Internet to several areas of rural Kenya. Their idea was to connect the communities to the Web by satellite. But there was a problem—the areas are not even connected to Kenya’s electric power supply. However, the young engineers offered the answer: solar panels. Energy from the sun powers the satellite by dishes (接收器) and computers that link the areas with the world outside. Kelly Moran, Joan Ervin and Tricia Donajkowski spent ten days in Kenya in November. The three women recently earned master’s degrees in space system engineering from the University of Michigan. People now have access to educational, medical and all kinds of other information. Farmers, for example, can easily find weather, crop and price information online.

The project began back at the college of engineering in Ann Arbor, Michigan in 2007. That was when 25 students in a class taught by Thomas Zurbuchen first talked about the idea. The goal was to test whether Internet stations could be set up, how much they would cost, and how long they could operate. But the engineers also had to consider other things such as social needs. Students from the public health and business schools offered advice. The young engineers also had to design the equipment to survive the heat in Africa. Prof, Zurbuchen praised his former students for “ making something work in a different climate far away from home.” Just 5% of Africans have Internet connections. The International Telecommunication Union says 1/3 of Kenyans have moble phones. But mobile phones may or may not work well with the Internet.

PDAs are very useful．They are like small computers．You can put a lot of information into them． For example．you can put in telephone numbers and e-mail addresses．Many people use PDAs to remember important dates．Some of these super machines can even send and receive e-mails．
PDAs are small and convenient．A few years ago，they were expensive．Now，they are cheap．Many people use them at work and at school．People can carry PDAs in their shirt pockets．
But，it’s important to be careful．These little machines are easy to lose．People put so much important information into their PDAs．It’s really terrible to lose them．
