The Netherlands on Monday launched its first?ever “intelligent bicycle”, fitted with a set of electronic devices to help bring down the high accident rate among elderly cyclists in this country.

The intelligent bicycle runs on electricity. Its seat shakes when other cyclists approach from behind, while the handlebars do the same when obstacles appear ahead to inform cyclists to pay attention to the danger. It also has a cradle (置物架) in which a computer can be inserted, to wirelessly connect and “talk” to the bicycle through a particular application. The computer also flashes a bright signal if there is an approaching obstacle in the bicycle's path, like a tree, or if another cyclist comes up from behind intending to pass.

A commercial?available bicycle is expected to be on the market in the next two years and should sell for between 1,700 euros to 3,200 euros per bicycle. It weighs about 55 pounds but researchers are working on making the on?board systems smaller.

“Accidents often happen when cyclists look behind them or get a fright when they are passed at high speed,”said Maurice Kwakkernaat, one of the scientists involved in the project, “The on?board system technology has already been at work in the automotive industry.”

“More and more elderly people are using a bicycle, not only for short distances, but also for longer distances,”Dutch Environment Minister Melanie Schultz van Haegen said.“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 enjoying cycling,” she said.

Where should an adventurous tourist go? After you've done sightseeing in London, shopping in New York, tasted the local food in Paris, and danced to your heart's content at the Brazilian Carnival, where else can you go? What exotic (异国风情的) tourist destination awaits you?

Well, Antarctica sounds like the holiday of a lifetime! It's considered the last great wilderness on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can cope with the low temperatures.

Tourism began in Antarctica in the 1950s and it's still a small scale. About 37,000 tourists are expected there this season, but many won't even leave the boat.

The BBC's Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave footprints and they all go to the same place, the accessible coastline, which is also where the penguins and seals go to breed.

But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.

According to Rix, guidelines are followed when you're about to set foot in Antarctica and tourists have to disinfect (为……消毒) their boots to make sure no alien species are introduced.

And once on land, there's no eating or smoking. Rocks, bone fragments — nothing should be taken as a souvenir and nothing should be left behind. Tourists fortunate enough to visit Antarctica must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.

1.According to the second paragraph, we can learn that ________.

A.Antarctica has become the best place for people to travel

B.only scientists can be allowed to go to Antarctica

C.Antarctica is less affected by human activities

D.no animals can survive in Antarctica except penguins

2.Juliet Rix's travel in Antarctica mentioned in the fourth paragraph indicates that ________.

A.governments should take measures to stop tourists from going to Antarctica

B.whether tourists should go to Antarctica or not should be considered carefully

C.the animals' habitat in Antarctica has been seriously affected by tourism

D.only journalists begin to pay attention to the environmental protection in Antarctica

3.Which of the following statements is TRUE according to Rix?

A.Tourists can eat and smoke in Antarctica.

B.Tourists can take something they like from Antarctica.

C.Tourists can throw away something they don't need in Antarctica.

D.Tourists can enjoy the beautiful scenery in Antarctica.

4.Which of the following is the best title of this passage?

A.Why can't tourists go to Antarctica?

B.How can tourists go to Antarctica?

C.Should tourists go to Antarctica?

D.Are tourists allowed to go to Antarctica?

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.

“Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status,” said Professor Ryan.

Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.

But in a former experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.

Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship.

Professor Ryan’s recent experiment used 62 men and women aged 20 to 37.

Half of the participants(参与者)received oxytocin. The other half received placebo (安慰剂).

After a week, the two groups switched with participants. They went through the same procedure with the other material.

Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.

The results indicated that, after treatment with oxytocin, men’s ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.

Professor Ryan thus concluded: “Our experiment proves that the hormone oxytocin can raise people’s abilities to better distinguish many kinds of social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal.”

1.What causes men and women to behave differently according to the text?

A. Placebo. B. Oxytocin.

C. The gesture. D. The social status.

2.What can we learn from Professor Ryan's former experiment?

A. Oxytocin affects our behavior in a different way.

B. Our body lets out oxytocin when we are deep in love.

C. Our body produces oxytocin when we feel unhappy about others’ success.

D. Oxytocin improves our abilities to understand people's behavior differences.

3.Why did Professor Ryan conduct the recent experiment?

A. To test the effect of oxytocin on the ability to recognize social interactions.

B. To know the differences between friendship and competition.

C. To know people’s different abilities to answer questions.

D. To test people’s understanding of body language.

4.The underlined word “distinguish” has the closest meaning to ______.

A.accept B.discover C.differ D.explore

5.The author develops the text by______.

A. explaining people’s behaviors

B. describing his own experiences

C. distinguishing sexual differences

D. discussing research experiments
