The Netherlands on Monday introduced its first-ever " intelligent bicycle , fitted with electronic devices to help bring clown 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 (震动的) 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

There is a lot of talk these days about how kids should be interested in science. Here’s an area of science for everyone, and these cool new books might inspire you to discover your inner scientist.
Scaly Spotted Feathered Frilled by Catherine Thimmesh, 58 pages, ages 9-12
Seeing a picture or a model of a dinosaur, do you wonder how anybody knows what they look like? After all, nobody has seen a living dinosaur. This book explains how scientists and artists work together to re-create dinosaurs. As scientific discoveries have been made, the models have changed. Scientific tests may one day expose what a dinosaur’s coloring was, but now artists have to use their imagination to determine how these huge creatures looked.
Beyond the Solar System by Mary Kay Carson, 128 pages, ages 10-13
This book takes readers back to the beginnings of space exploration—thousands of years ago, when people began star observation—and forward to today’s search for planets in distant parts of the Milky Way. Along with history lessons, readers get 21 activities, such as making a black hole and creating a model of Albert Einstein’s universe using a T-shirt. The activities are perfect for cold winter days.

A
An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.
In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起)the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.
In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighbourhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.
The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity can be achieved .Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.
Ultimately as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
1.What is the purpose of the project launched by Nancy?
A. To invite authors to guide readers.
B. To encourage people to read and share.
C. To involve people in community service.
D. To promote the friendship between cities.
2.According to the passage, where would the project be more easily carried out?
A. In large communities with little sense of unity
B. In large cities where libraries are far from home
C. In medium-sized cities with a diverse population
D. In large towns where agreement can be quickly reached
3.The underlined words “shared a word” in Paragraph 5 probably mean_____.
A. exchanged ideas with each other
B. discussed the meaning of a word
C. gave life experience
D. used the same language
4.According to Nancy, the degree of students of the project is judged by ______.
A. the careful selection of a proper book
B. the growing popularity of the writers
C. the number of people who benefit from reading.
D. the number of books that each person reads.

What’s on Your Pet’s Mind?
In 1977, Irene Pepperberg of Harvard University began studying what was on another creature’s mind by talking to it. Her first experiments began with Alex. Alex was a one-year-old African grey parrot and Irene taught him to produce the sounds of the English language. “I thought if he learned to communicate, I could ask him questions about how he sees the world.”
At the time, most scientists didn’t believe animals had any thoughts. They thought animals were more like robots but didn’t have the ability to think or feel. Of course, if you own a pet you probably disagree. But it is the job of a scientist to prove this and nowadays more scientists accept that animals can think for themselves.
“That’s why I started my studies with Alex,” Irene said, “Some people actually called me crazy for trying this.”
Nowadays, we have more and more evidence that animals have all sorts of mental abilities. Sheep can recognize faces. Chimpanzees (黑猩猩) use a variety of tools and even use weapons to hunt. And Alex the parrot became a very good talker.
Thirty years after the Alex studies began. Irene was still giving him English lessons up until his recent death. For example, if Alex was hungry he could say “want grape”. Alex could count to six and was learning the sounds for seven and eight. “He has to hear the words over and over before he can correctly say them.” Irene said, after pronouncing “seven” for Alex a few times in a row. Alex could also tell the difference between colors, shapes, sizes, and materials (e.g. wood and metal). Before he finally died, Alex managed to say “seven”.
Another famous pet that proved some animals have greater mental skills was a dog called Rico. He appeared on a German TV game show in 2011. Rico knew the names of 200 different toys and easily learned the names of new ones. When Rico became famous, many other dog owners wanted to show how clever their pets were. Another dog called Betsy could understand 300 words.
One theory for dogs’ ability to learn a language is that they have been close companions to humans for many centuries and so their ability to understand us is constantly evolving (进化). While animals can’t do what humans do yet, some scientists believe that examples like Alex and Rico prove that evolution develops intelligence, as well as physical appearance.
1.Irene wanted to find out __________.
A. what a parrot thinks
B. why a parrot can speak
C. how parrots make sounds
D. if parrots speak English
2.Alex learnt new words by __________.
A. singing them
B. reading them
C. writing them
D. rehearing them
3.The two dogs mentioned in the article could _______.
A. understand some words
B. recognize strange voices
C. copy human gestures
D. tell different colors
4.The article concludes that ___________.
A. our pets understand what we say
B. dogs may speak to humans one day
C. humans are related to chimpanzees
D. mental ability can evolve in animals

Many people turn to doctors or self-help books, but they ignore(忽视) a powerful thing that could help them fight illness: their friends.
Researchers are only now starting to pay attention to the importance of friendship in health. A 10-year Australian study found that old people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk(风险) for obesity (肥胖) among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could improve brain health as we age.
“In general, the role (作用) of friendship in our lives isn’t well realized,” said Rebecca, a professor at the University of North Carolina. “Friendship has a bigger effect on our psychological (心理的) health than family relationships.”
While(尽管) many friendship studies are about the close relationships of women, some research shows that men can benefit, too. In a six-year study of 736 middle-aged men, having friendships reduces the risk of heart attack. Only smoking was as important a risk factor (因素) as having little social support.
Exactly why friendship has such a big effect isn’t entirely(完全) clear. While friends can send a sick person to the hospital or pick up medicine, the benefits go well beyond physical assistance. Friendship clearly has a big psychological effect. “People with stronger friendships feel like there is someone they can turn to,” said Karen, a doctor. “The message of these studies is that friends make your life better.”
1.The three studies in the second paragraph show that ______.
A. old people need friends the most
B. friends can help us lose weight
C. social ties are connected to health
D. more friends make us healthier
2.What do Rebecca’s words in the 3rd paragraph mean?
A. Friendship is more important to women than to men.
B. What people need most is a friend’s care.
C. Friendship is more important than family relationship.
D. The value of friendship hasn’t been fully understood.
3.The author mentioned smoking in the 4rd paragraph to discuss ______.
A. the cause of heart attack B. the risk of having no friends
C. smoking is bad for men D. friends’ influence on habits
4.What would be the best title of the text?
A. Friends are better than medicine
B. Friends are as important as a family
C. Having good friends leads to a healthier life
D. Friendship makes people happy
