The Netherlands on Monday introduced its first-ever intelligent bicycle, fitted with electronic devices to help bring down the high accident rate among elderly cyclists in the bicycle-mad country.

Developed for the government by the Netherlands Organization for Applied Scientific Research (TNO), the intelligent bicycle, runs on electricity.A commercial-available bicycle is expected to be on the market in the next two years and should sell for between 1, 700 to 3, 200 euros per bicycle.

The devices on the bike are linked through an onboard computer with a vibrating (震動(dòng)的) warning system fitted in the bicycle's saddle and handlebars to warn cyclists of the coming danger.

The saddle vibrates when other cyclists approach from behind, while, the handlebars do the same when barriers appear ahead.

“Accidents often happen when cyclists look behind them or get a fright when they are passed at high speed, ”said Maurice Kwakkernaat, one of TNO's research scientists involved in the project.“The onboard system technology has already been at work in the car industry, ”he said.

“More and more elderly people are using a bicycle, not only for short distances, but also for longer distances, ”Dutch Environment and Infrastructure Minister Melanie Schultz van Haegen told AFP.“This type of bicycle is truly needed in the Netherlands because it will help us bring down the number of elderly people who are injured every year and allow them to continue to enjoy cycling, ”she said.

In the Netherlands, bicycles outnumber the population of 17 million by at least one million and there are some 25,000 km of bicycle path in the country.Those statistics are set to grow as more and more people take to two-wheeled transport, leading to an increased risk of injury.

Last year, 184 cyclists died in the country, of which 124, or 67%, were older than 65, according to the Central Statistics Office.The year before, 200 cyclists died, the majority of victims also being elderly.

The current model weighs 25 kilograms but researchers are working on making the onboard systems smaller.

1.The intelligent bicycle is aimed to ________.

A.protect the environment

B.help reduce traffic pressure

C.popularize the use of bicycles

D.improve safety for elderly cyclists

2.Which part of the intelligent bicycle will vibrate when another cyclist was suddenly found ahead ?

A.The handlebars.

B.The wheels.

C.The saddle.

D.The onboard computer.

3.We can learn from the passage that ________.

A.the elderly ride bicycles wherever they go

B.the accident rate among elderly cyclists is high

C.the number of elderly cyclists is decreasing

D.the elderly are planning to give up cycling

4.Which is the best title for the passage?

The Enigma(謎)of Beauty

The search for beauty spans centuries and continents.Paintings of Egyptians dating back over 4,000 years show both men and women painting their nails and wearing makeup.In 18th-century France, wealthy noblemen wore large wigs (假發(fā)) of long, white hair to make themselves attractive.Today, people continue to devote a lot of time and money to their appearance.

There is at least one good reason for the desire to be attractive: beauty is power.Studies suggest that good-looking people make more money, get called on more often in class, and are regarded as friendlier.

But what exactly is beauty? It’s difficult to describe it clearly, and yet we know it when we see it.And our awareness of it may start at a very early age.In one set of studies, six-month-old babies were shown a series of photographs.The faces on the pictures had been rated for attractiveness by a group of college students.In the studies, the babies spent more time looking at the attractive faces than the unattractive ones.

The idea that even babies can judge appearance makes perfect sense to many researchers.In studies by psychologists, men consistently showed a preference for women with larger eyes, fuller lips, and a smaller nose and chin while women prefer men with large shoulders and a narrow waist.According to scientists, the mind unconsciously tells men and women that these traits—the full lips, clear skin, strong shoulders—equal health and genetic well-being.

Not everyone thinks the same way, however.“Our hardwiredness can be changed by all sorts of expectations—mostly cultural,” says C.Loring Brace, an anthropologist at the University of Michigan.What is considered attractive in one culture might not be in another.Look at most Western fashion magazines: the women on the pages are thin.But is this “perfect” body type for women worldwide? Scientists’ answer is no; what is considered beautiful is subjective and varies around the world.They found native peoples in southeast Peru preferred shapes regarded overweight in Western cultures.

For better or worse, beauty plays a role in our lives.But it is extremely difficult to describe exactly what makes one person attractive to another.Although there do seem to be certain physical traits considered universally appealing, it is also true that beauty does not always keep to a single, uniform standard.Beauty really is, as the saying goes, in the eye of the beholder.

1.People’s ideas about beauty _______.

A.have existed since ancient times

B.can be easily described

C.have little influence on a person’s success

D.a(chǎn)re based upon strict criteria

2.In Paragraph 3, the babies in the study _______.

A.were rated for their appearance

B.were entered in a beauty contest

C.were shown photos of a group of college students

D.were able to tell attractive faces from unattractive ones

3.The underlined word “traits” in Paragraph 4 probably means _______.

A.Qualities

B.measurements

C.Judgments

D.standards

4.We can learn from the passage that _______.

A.the ideas of beauty vary as people grow up

B.the search for beauty is rooted in lack of confidence

C.the standards for beauty are based on scientific researches

D.the understanding of beauty depends on cultural backgrounds

Laws that would have ensured pupils from five to sixteen received a full financial education got lost in the “wash up". An application is calling on the next government to bring it back.

At school the children are taught to add up and subtract(減法) but, extraordinarily, are not routinely shown how to open a bank account-let alone how to manage their finances in an increasingly complex and demanding world.

Today the parenting website Mumsnet and the consumer campaigner Martin Lewis have joined forces to launch an online application to make financial education a compulsory element of the school curriculum in England. Children from five to sixteen should be taught about everything from pocket money to pensions, they say. And that was exactly the plan preserved in the children,schools and families bill that was shelved by the government in the so-called ¨wash-up" earlier this month-the rush to legislation before parliament was dismissed. Consumer and parent groups believe financial education has always been one of the most frustrating omissions of the curriculum.

As the Personal Finance Education Group (Pfeg) points out, the good habits of young children do not last long. Over 75% of seven to ll-year-olds are savers but by the time they get t0 17, over half of them are in debt to family and friends. By this age, 26% see a credit or overdraft(透支)as a way of extending their spending power. Pfeg predicts that these young people will “find it much harder to avoid the serious unexpected dangers that have been fallen many of their parents' generation unless they receive good quality financial education while at school".

The UK has been in the worst financial recession(衰退)for generations. It does seem odd that-unless parents step in-young people are left in the dark until they are cruelly introduced to the world of debt when they turn up at university. In a recent poll of over 8,000 people, 97% supported financial education in schools, while 3% said it was a job for parents.

1.The passage is mainly about

A. how to manage school lessons

B. how to deal with the financial crisis

C. teaching young people about money

D. teaching students how to study effectively

2.It can be inferred from the first two paragraphs that

A. the author complains about the school education

B. pupils should not be taught to add up and subtract

C. students have been taught to manage their finances

D. laws on financial education have been effectively carried out

3.The website and the consumer campaigner joined to

A. instruct the pupils to donate their pocket money

B. promote the connection of schools and families

C. ask the government to dismiss the parliament

D. appeal for the curriculum of financial education
