The Netherlands on Monday launched its first-ever “intelligent bicycle”, fitted with a set of electronic devices (设备) 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 (插入), 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 frightened 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 (自动的) 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．
1.What does the text mainly talk about?

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 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 other cyclists approach it from behind?
A. The saddle. B. The wheels.
C. The handlebars. D. The onboard computer.
3.We can learn from the passage that ________.
A. the elderly ride bicycles wherever they go
B. the elderly are planning to give up cycling
C. the number of elderly cyclists is decreasing
D. the accident rate among elderly cyclists is high

WASHINGTON, D.C. --- The FBI on Monday released new data about hate crimes. It showed that more hate crimes were carried out in the United States last year. There was an increase in incidents motivated by intolerance against Jews, Muslims and LGBT people, among others. The term LGBT includes lesbian, gay, bisexual and transgender people.
There were more than 6,100 reported incidents of hate crimes in 2016, up from more than 5,800 the year before. The FBI made this report based on data submitted by law enforcement(执行) agencies across the country. The new data follows a trend from 2015. The trend shows that the largest share of victims last year, nearly six in 10, were targeted(为目标) due to intolerance against the victim's race or ethnicity.
The number of hate crimes caused by intolerance against a person's race or ethnic background rose to 3,489 from 3,310 a year earlier, the FBI report said. Half of those hate crimes were caused by racism against African-American people. One in five victims were targeted because of their religion. One in six were due to sexual orientation, the report said.
The FBI data gains a general look at hate crime in the nation. But this report is considered incomplete because not all areas report their hate crimes. According to the FBI, 88 percent of agencies choosing to participate in the hate crime statistics program “reported that no hate crimes occurred” in their areas last year.
Speaking earlier this year after a series of threats targeting Jewish schools and community centers, former FBI director James B. Comey admitted this. He said that the bureau needs "to do a better job of tracking and reporting hate crime." Only then can we understand what is happening and how to stop it.
“Hate crime is different from other crime,” Comey said in prepared remarks delivered in May. “They damage at our sense of self, our sense of belonging. The end result is loss: loss of trust, loss of dignity, and in the worst case, loss of life.”
The FBI report, which collects information on the offenders in the hate crimes tallied(总计) last year, found that the largest share, nearly half were white. About a quarter of the people who carried out hate crimes were African-American.
Four in 10 of the people identified as “known hate crime offenders” committed simple assault. This could mean a threat of violence or causing a minor injury. Nearly a quarter committed aggravated(=serious) assault, which is more serious and often involves the use of a deadly weapon. The report also identified more than 1,600 people who committed hate crimes by damaging, vandalizing or trying to destroy property.
1.The author emphasizes the situation of hate crimes mainly by using ________.
A.examples B.statistics
C.comparison D.quotation
2.Why is hate crime different from other crimes in the article?
A.The article highlights that hate crimes are more likely to end with injuries.
B.The article emphasizes that hate crimes target people’s sense of belonging.
C.The article explains that hate crimes are tracked more often than other crimes.
D.The article shows that hate crimes occur more often in minority communities.
3.Which of the following are the results of hate crimes? ______.
①violence or injuries ②loss of dignity or life ③damage to property ④ use of deadly weapons
A.①②③④ B.②③④
C.①③④ D.①②③
4.What’s the genre of this passage?
A.News report. B.Argumentation.
C.Description. D.Research report.

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins. The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.

A spaceship is flying to the sun in summer 2018! It will be the first-ever to a star and will be one of the biggest achievements space exploration (探险) in human history. The purpose is to study the sun’s outer atmosphere and better understand how stars work.
The spaceship, with no man inside, will fly within 4 million miles of the sun’s surface - right into the solar atmosphere, where the temperature is over 4,500°C. To protect the spaceship, it is covered with a 12cm-thick coating.
The spaceship is called Parker Solar Probe and it is named after Eugene Parker, a professor from the University of Chicago. It’s the first NASA spaceship to be named after a researcher who is still alive. In 1958, Eugene Parker first created the term “solar wind”-the sun sending out a flow of particles (颗粒) and energy.
“The spaceship is going where it has never been before. It’s very exciting that we’ll finally get to know more about the solar wind. I’m sure there will be some surprises. There always are,” said Professor Parker.
Parker calls it a heroic scientific space adventure, and he means that the spaceship will have to experience high temperatures and sun radiation (辐射). “The spaceship is going to do the hottest and fastest work. I love to call it the coolest hottest work under the sun,” said Scientist Fox Nasa.
1.Why is a spaceship flying to the sun?
A. To make a human history record.
B. To take the first-ever trip to the star.
