New Research Lights the Way to Super-fast Computers

(1) New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.<br>

(2)The research by the University of Surrey, in collaboration with the University of Cambridge and the University of Southampton, has found it is possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs.<br>

By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems.<br>

(3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the Internet rely on optical systems; the transfer of information using light. Optical fibers are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signals once they reach a computer, causing a significant slowdown in processing.<br>

(4) "The challenge is to find a single material that can effectively use and control light to carry information arotmd a computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey.<br>

(5) "This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as &39;pn-junction&39; devices. This should enable the material to act as a light source, a light guide and a light detector -- something that can carry and interpret optical information. In doing so, this could transform. the computers of tomorrow, allowing them to effectively process information at much faster speeds."<br>

(6) The researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.<

Paragraph 2 __________ 查看材料

A.Expectation of the discovery

B.The problem of current computers

C.A new finding

D.The purpose of the research

E.Public reaction to the discovery

请根据短文内容,回答题。

Travel to Moon

The National Aeronautics and Space Administration (NASA) has announced plans to return people to the moon by 2018. "And this time," according to a NASA press release, “we&39;re going to stay."<br>

NASA wants to make a new spaceship for the missions using parts from the Apollo program,which first took people to the moon in 1969, and the space shuttle. NASA says the new Crew Exploration Vehicle (CEV) will be "affordable, reliable, and safe".<br>

The CEV will be able to hold four astronauts. The plan is to have the CEV dock (对接) in space with the lunar- the vehicle astronauts will use to land on the moon- which will be launched separately into space. The CEV will then travel to the moon and all four astronauts will walk on the moon.<br>

The first m, oon missions are expected to last up to seven days. Exploration and construction of a moon base will be the astronauts&39; top priorities (最优先考虑的事). NASA hopes to have a minimum of two moon missions a year starting in 2018. This will allow for quick moon base construction, constant scientific study, and training for future missions to Mars.

What is new in NASA‘s plan to return to the moon by 2018? 查看材料

A.People will land find remain on the moon

B.Equipment will be carded and installed there

C.More CEVs will be made regularly

D.A special device will be used in landing

根据下面短文内容,回答题。

New Product Will Save Lives

Drinking water that looks clean may still contain bugs (虫子), which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Parton, who started Genera five years ago. He and his employees have developed the test together with a British water company.

Andy Headland, Genera&39;s marketing director, recently presented the test at a conference in the USA and forecasted good American sales for it. Genera has already sold 11 of its tests at $42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.

Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.

Genera Technologies has developed a method that determines whether water is clean. 查看材料
