Traffic problems are an everyday concern in many cities, including Washington, D. C. A growing number of Washingtonians are turning to bicycles to get to and from work. In fact, the number of commuters who use bicycles has doubled in the city since 2007.

Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University,popularly known as Virginia Tech. He has written a book about urban biking, called City Cycling. He says there is a reason why urban bike tiding is now becoming more popular.

“Over the last 60 to 70 years, cities in America have been adapted to the automobile.”

“Most cities took advantage of the money coming for the interstate (洲际)highway system, from the federal government, starting in 1956. There was a 90 percent federal match(补贴)so the cities only had to put up 10%. It was very tempting.(临时的).”

In the years after World War Two, many Americans moved to suburban communities, just outside major cities, They decided to travel great distances to and from work in exchange for a home in the suburbs. Their cars became a symbol of freedom.

But today, many people believe they can save money by living in the city.

Greg Billing is with the Washington Area Bicyclist Association. “When a person makes a change from using a car to using a bike, he/she is saving anywhere between 8 or$9,000 a year.”

Ralph Buehler says governments save money when people use bicycles. “Building bicycling facilities(设施) is much cheaper than building and maintaining road facilities or public transport.”

Washington, D.C has also taken steps to protect bike riders. It approved a safe passing law and created areas on the road between cars and bikes.

The United States Census Bureau says 4% of the city’s workers ride to work by bike. The only city on the East Coast with more bike commuters is New York.

3.In the years after World War Two, many Americans prefer to_____.

4.What do Ralph Buehler and Greg Billing agree with?

People are being lured(引诱)onto Facebook with the promise of a fun and free service without realizing they’re paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Facebook, because people don’t really know what their personal details are worth.

The biggest problem, however, is that the company keeps changing the rules. Early on, you could keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends’ names—were set, by default(默认), to be shared with everyone on the Internet.

According to Facebook’s vice-- president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information, they have a “less satisfying experience.”

Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they’re online connecting with their friends?

The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Commission to set guidelines for social-networking sites. “I think the senators rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.

I suspect that whatever Facebook has done so far to invade our privacy, it’s only the beginning, which is why I’m considering deactivating(撤销)my account. Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t know. That is too high a price to pay.

D. It profits by selling its users’ personal data

A. Setting guidelines for advertising on websites

B. Banning the sharing of users’ personal information

C. Removing ads from all social—networking sties

D. Formulating (制订)regulations for social—networking sties

4.Why does the author plan to cancel his Facebook account?

A. He is dissatisfied with its current service

B. He doesn’t want his personal data abused

C. He finds many of its users untrustworthy

D. He is upset by its frequent rule changes

When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.

Now, houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock(家畜).During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.

People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy-saving.

House-building becomes a great challenge(挑战)to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy-saving houses.

1.What did people begin to consider as electricity was no longer cheap?

A. The climate of their areas. B. The energy for their houses.

C. The fashions for their houses. D. The building materials for their houses.

2.People in some areas gain a source of heat by _________.

A. keeping their livestock downstairs

B. protecting their livestock from the cold

C. sharing their houses only with their cows

D. living on the second floor with their livestock

3.The underlined words “natural law” in the third paragraph refer to the fact that ________.

A. heat raises the temperature in the houses

B. heat goes in the upward direction

C. heat goes up if temperature is raised

D. heat increases the temperature of rocks

4.From the passage, we can conclude that __________.

A. people will no longer consider building materials in the future

B. energy-saving buildings will become more popular in the future

C. almost all people will move into the houses heated by large rocks

D. energy engineers will devote themselves only to modern technology

The ride-sharing company Uber has removed its self-driving cars from the streets of San Francisco,California. The action came after a dispute between Uber and state officials over whether the vehicles needed special permits to operate.

Uber recently launched testing of its self-driving service in San Francisco.But shortly after the launch, California's Department of Motor Vehicles (DMV) told the company to stop the self-driving vehicles.State officials said the Uber cars needed the same special permit given to about 20 other companies testing self-driving technology in California.Uber argued that its technology does not make vehicles fully autonomous,and so the special permit was not needed.It added that all of Uber's "self-driving" cars have a driver sitting in the passenger seat to take over if needed.

The head of Uber's self-driving technology,Anthony Levandowski,explained the company's position in a blog post.He said the self-driving Uber vehicles do use high-technology tools to assist drivers.But they are not fully autonomous and require a driver to be at the controls at all times..He compared the technology to solar carmaker Tesla's advanced driver assist tools.Telsa's Autopilot system allows its cars to steer in a lane,change lanes,and speed up or slow down based on nearby traffic.The company tells drivers that,when using Autopilot,they should still always be ready to take control of the vehicle.Vehicles equipped with these high-tech driver assist tools do not need a special permit to operate in California.

It's hard to understand why the DMV would seek to require self-driving Ubers to get permits when it accepts that Tesla's autopilot technology does not need them,"Levandowski wrote.San Francisco's mayor,Ed Lee,praised the DMV for stopping Uber's self-driving vehicles.He said he supports self-driving development and testing.But only under conditions that put human bicyclists' and pedestrian safety first."

1.What does the underlined word "dispute" in Paragraph 1 mean?

A. Discussion. B. Disagreement.

C. Fighting. D. Meeting.

2.Why does Uber say that the special permit was not needed?

A. Because Uber's "self driving" cars are fully autonomous.

B. Because there are passenger seats in Uber's "self-driving" cars.

C. Because no drivers are needed in some Uber's "self-driving" cars.

D. Because Uber's "self-driving" cars can be operated by humans when necessary.

3.What can we know from the passage?

A. Uber's self-driving cars need human drivers.

B. Telsa's Autopilot needs special permits too.

C. Uber's self-driving cars are completely autonomous.

D. Telsa's Autopilot system is better than Uber's self-driving technology.

4.What can we infer from Ed Lee's words?

A. He doesn't think DMV is right.

B. Uber's self-driving cars should he supported.

C. Uber's serf-driving cars are not safe enough.

D. One should be careful while walking or cycling in streets.
