COOL INVENTIONS

From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行進) around the neighborhood has never been better.

Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (電極) inside the water tank. Water contains ions (離子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.

Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流線型的), the driver lies back at a 45-degree angle.

You're having a blast at your friend's birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.

According to the passage, the Venturi Eclectic      .

A. is popular with businessmen     B. is suitable for a long trip

What is the common characteristic of the Venturi Eclectic and the Bedol Water-powered Clock?

C. blowing out a candle D. recording sounds

Which of the following is TRUE according to the passage?

A. The Triops is sensitive to sounds.

Britain’s oldest man made his first visit to London yesterday at the age of 101. Mr John Evans, who spent 60 years working as a miner in South Wales, had never found the time or money to make the trip from his home in Forest–fach, near Swansea. “There was a trip to the White City, but it was ten shillings’ return from Swansea—too much I thought. All my money went to the family then,” he said. But when British Rail offered him an all–expense–paid birthday gift to the capital, he just could not refuse.

He arrived at Paddington Station in his best suit, favorite Panama hat and a red rose in his buttonhole. “It’s very exciting. There’s no doubt about it,” he said.

Until yesterday he had never been far from home. “But I’ve been on the seas to that faraway land called Fracombe 21 miles from home,” he joked. During the next two days Mr Evans will be taken on a short tour of London to see the sights. Top of his list is a visit to the House of Parliament.

The only arrangement he does not like is the wheelchair provided for him if he gets tired. “I don’t like the chair—people will think I am getting old,” he said. His secret for a long and healthy life has been well publicized—no wine, no tobacco and no anger.

Before setting off from Swansea with his 76–year–old son, he said jokingly, “I’m glad to see they’ve given me a return ticket.”

1.Mr. Evans didn’t go to see the world because he                .

A. had already been on the seas to Fracombe                 B. was too busy to go too far away from home

C. couldn’t afford both the time and money   D. believed “East or west, home is the best”

2. Mr Evans didn’t like the wheelchair because                 .

A. he was not used to traveling in it

B. the wheelchair was not easy to operate

C. he preferred walking to sitting in it at home

D. he thought he was still young enough to manage the trip

3.The probable explanation to Mr Evans’ long life lies in                  .

A. his good living habits       B. his hard working for the family

C. his sticking to his hometown D. his living conditions near the Swansea

One of the world's richest men has taken a close interest in one of man's most basic functions: visiting the toilet．Bill Gates’ charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world．
So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount of potential drinking water．Secondly, they are more likely to cause pollution．This is a real problem in many areas of the developing world, where, according to United Nations’ estimates, unsafe sanitation causes half of all hospitalizations．Younger people are particularly at risk．Illnesses which cause diarrhea are responsible for the deaths of about 1．5 million children a year．Finally, standard lavatories simply aren't practical in remote areas．
The challenge set by Bill Gates was to come up with a latrine which works without running water, electricity or aseptic tank．It also needed to operate for less than 5 cents．28 designs were displayed at the recent event of the Toilet Fair in Seattle, USA．Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing．
But the winner was a solar-powered design which generated hydrogen gas and electricity．The team from the California Institute of Technology（CIT）picked up a prize of $ 100,000.
But clearly Bill Gates doesn't feel he's flushing money down the toilet．After the Seattle event he said, "We couldn't be happier with the response we've gotten," Gates has even promised $370 million more to the future toilet project．They hope to field test more prototypes over the next three years．
【小題1】Why is Bill Gates paying people to invent new toilets?
