Question

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.

Adaptive glasses

Do you wear glasses? If so，can you imagine life without them? In 1985，Joshua Silver，a professor at Oxford University，asked himself，“Can I invent a pair of glasses that could be changed by the wearer？”He designed two plastic lenses(透鏡) that are filled with a special liquid.Using syringes(注射器) you change the liquid between the lenses until you can see clearly.The glasses are not beautiful but they are easy to use and cheap to make.

The wind­up radio

When you switch your TV on tonight，think about all those people without electricity.Thinking about this，Trevor Baylis came up with the idea of designing a radio that could be powered by hand.In common with Joshua Silver he wanted his invention to be cheap and easy to use.He wanted even the poorest people in developing countries，who don't have electricity and cannot afford batteries，to use it.The radio has a generator(發(fā)電機(jī)) which is powered by turning a handle.In 1996 it won the BBC Design Award for Best Product and Best Design.

The Dyson vacuum(真空) cleaner

In many homes around the world you can see a cleaner that looks like a spaceship.This is the Dyson vacuum cleaner which uses something called “cyclonic，separation” to separate the dirt.You do not need a bag for your cleaner and it does not get blocked so it is very practical.The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner.He decided he could design a better one and in 1993 he opened his own factory.The Dyson is now one of the bestselling cleaners in the UK and Dyson is believed to have earned over a billion pounds.

The Zapata Flyboard

Have you ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a flyboard，built by water sports enthusiast Frank Zapata.With it you can dive back in the water and out again.It's possible to jump to incredible heights out of the water—over 30 feet.The basic flyboard model comes in at ￡4，200.

So keep dreaming and inventing.One day you might get it right.

Answer 1

本文通過向大家介紹近期英國(guó)的幾項(xiàng)發(fā)明來(lái)鼓勵(lì)大家積極思考，發(fā)明新事物。

16．D　主旨大意題。根據(jù)文章內(nèi)容可知，作者意在通過介紹英國(guó)最近的幾項(xiàng)發(fā)明來(lái)鼓勵(lì)人們創(chuàng)新思維并進(jìn)行發(fā)明創(chuàng)造，故D項(xiàng)作為本文的標(biāo)題最合適。

17．D　細(xì)節(jié)理解題。根據(jù)“Adaptive glasses”介紹中的最后一句“The glasses are not beautiful…”可知，這種眼鏡并不美觀。

18．B　細(xì)節(jié)理解題。根據(jù)“The wind­up radio”介紹中的最后一句“In 1996 it won the BBC Design Award for Best Product and Best Design.”可知答案為B項(xiàng)。

19．A　推理判斷題。根據(jù)“The Dyson vacuum (真空) cleaner”介紹中的“The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner.”可推知，發(fā)明者Dyson之所以有這樣的創(chuàng)意是由于以前他自己在使用真空吸塵器時(shí)感到很不方便，故答案為A項(xiàng)。
