A Battery’s Nightmare

Portable electronics that can be carried about easily are only as good as their batteries (电池) and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go.

The engine---about the size of a ten-cent coin---starts with a combustion chamber (燃烧室) that burns hydrogen. Its tiny parts are etched (蚀刻) onto silicon wafers (硅片) in the same manner that computer parts are etched onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.

But the devil in all this nice detail is efficiency. Tiny engine parts don’t always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.

The scientists’ goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t likely until at least the end of the next ten years.

1.According to the passage, the title suggests that _______ .

A. batteries should be greatly improved

B. petrol will be used instead of batteries

C. the time of batteries will be gone forever

D. pollution problems caused by batteries must be solved

2.What’s the meaning of the underlined word “devil” in paragraph 3?

A. Problem     B. Advantage     C. Invention     D. Technique

3.What can we infer from the passage?

A. The new invention doesn’t need any fuel.

B. The new engine has been produced in large quantities.

C. The new invention is much cheaper than the battery.

D. The new engine needs to be improved before it’s on sale.

In South Korea, children get used to the Internet at an early age. A survey last year by the Ministry of information and Communication showed that nearly half of children between the age of 3 and 5 use the internet.

“In south Korea, the Internet has become a babysitter, said Lee Kyong Ko, a professor at Duksing, Women’s University in Seoul.

Online role-playing games, where participants make friends and band together, have a strong appeal to Koreans,“One problem with those games is that you build your online person through countless hours of battles, and you develop a huge emotional attachment to your game character,”said Chang Woo Min, a one-time online gamer.

Parents report that their children steal money and do not come home for days and even weeks, practically living in Internet Cafes, and sometimes they refuse to look for jobs and play games all night and sleep during the day.

The authorities require Internet cafes to keep their distance from schools, and they open camps for teenage addicts and distribute booklets(小册子) on the dangers of game addiction. In addition, they are training hundreds of counselors, who visit schools and Internet Cafes.

In the 28,000 Internet Cafes in South Korea, persons under 18 are banded from entry after 10 p.m.. The authorities have even discussed reducing the points of gamers who play for more than three consecutive (连续的) hours, But such talks have produced no agreement, amid concerns that such restrictions would put a high-growth industry in danger and worse the problem of teenagers stealing adult online identification numbers,“Sooner or later we will be able to announce our measures,”the minister of Information and Communication, Rho Jun Hyoung, said at a news conference in May.“Since South Korea is one of the most active and developed countries in the Internet, the world is paying great attention to What policy we will adopt on this problem.”
