News item 1
原文：
Beidou, which means the Big Dipper in Chinese, has been providing accurate and stable services to Asia-Pacific users since China launched it a year ago. It has improved its accuracy to an error margin as low as five meters, down from 10, and can be further improved to be within centimeters. That will make it competitive with the US Global Positioning System.
Ran Chengqi, director of the China Satellite Navigation Office, says Beidou has functionality and performance “comparable” to the GPS system, but is cheaper.
It is estimated that the market for transportation, weather, and telecom spin-off services from Beidou could be worth 200 billion yuan, or more than 30 billion US dollars, by 2015.
Meanwhile, China is encouraging other countries in Asia to adopt the free service.
问题：
1. What will make Beidou competitive with the US Global Positioning System?
2. How much is Beidou’s estimated market worth by 2015?
News item 2
原文：
University of Washington researchers said they used a laser to turn hot water into cool water. Five engineers from the university are the first in the 50-year history of the laser to refrigerate liquids under normal conditions with light beams.
The group used a simple approach to the experiment. Lasers are known for producing hot temperatures. University of Washington said they “essentially ran the laser phenomenon in reverse.”
The discovery has a future in the computer and medical fields. Computer interiors could be cooled by lasers. In a medical laboratory, individual cells could be cooled to see how they react.
“Few people have thought about how they could use this technology to solve problems because using lasers to refrigerate liquids hasn’t been possible before,” said researcher Peter Pauzauskie.
The cool laser concept can also be used in manufacturing, telecommunications or national defense.
The group has an interest in hearing from businesses or scientists who may have everyday applications of the cool laser.
The findings were published this month in the Proceedings of the National Academy of Sciences.
问题：
1. What is the news mainly about?
2. How can the new discovery be used in the computer field?
3. What fields can the cool laser concept be used in?
News item 3
原文：
Three university students in Santiago, Chile have developed a plant-powered device to charge their mobile phones.
The three engineering students got the idea for the device while sitting in their school’s courtyard. Their invention is a small biological circuit they call E-Kaia. It captures the energy plants produce during photosynthesis.
A plant uses only a small part of the energy produced by that process. The rest goes into the soil. E-Kaia collects that energy. The device plugs into the ground and then into a mobile phone.
One of the student inventors, Camila Rupcich, says the device changes the energy released from the plant into low-level power to charge phones.
The E-Kaia is able to fully recharge a mobile phone in less than two hours.
问题：
1. How does E-Kaia produce power?
2. How long does E-Kaia take to fully recharge a mobile phone?
练习过后，和小编一起看一下科技类短新闻语言特点吧！
1. 英语科技新闻大量使用直接引语或间接引语。
这类新闻经常会引用当事人、专家或行家的原话来报道科学发现或技术发明的经过以及科学发现或技术发明的意义，且多用长句。
