閱讀下面短文并回答問題，然后將答案寫到答案卡相應(yīng)的位置上。

[1] Scientists in the United States are working on a technology that uses human energy to power devices like cell phones, laptop computers, and GPS systems.

[2] Tom Krupenkin, who teaches electrical engineering at the University of Wisconsin and his team want to reduce dependence on costly and polluting batteries. Instead of using batteries for power, they have turned to human beings and have placed a device in a shoe that collects and stores energy from human motion and turns it into electricity. One part of this device is an energy harvester. It has two small containers filled with thousands of very small drops of liquid. These droplets get pushed back and forth as a person walks and can directly convert it into electric power. Output of this energy is stored in a regular rechargeable tiny battery of the style that we have in cell phones.

[3] The team has also developed a system to permit use of the stored energy by common mobile devices. It does not require connections with wires, and can be used to create a wireless signal. A cell phone that uses the wireless “hotspot” from the shoe would use much less power if   __________   a wireless telephone network. The devices are about the size of a credit card. Professor Krupenkin says the system is always powered. So unlike a traditional battery, this energy harvester never needs to be recharged.

[4] The professor says he does not expect this invention to replace traditional batteries. But it will help reduce dependence on them. He says there are a huge number of possible uses for this technology. Professor Krupenkin thinks the technology would be useful for people in rural areas where there is no electrical power.

[5] He stresses that it makes a lot of sense for people who depend on devices like mobile phones and laptop computers. And he says the technology could be used by soldiers who must carry battery–powered electronic devices into difficult territory(地區(qū)).
