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.

【廣西玉林市、貴港市2017屆高中畢業(yè)班質量檢測】D
While dog keepers realize their dogs can read their moods accurately,scientists have always been a little doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna,Austria,we finally have some convincing evidence.
For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That’s because the scientists believe humans show their emotions on their entire face.
After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.
They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
1.How did the scientists conduct the experiment?
A. By mixing the selected dogs together.
B. By leaving dogs to women who are either happy or angry.
C. By showing digital pictures of women’s happy or angry faces.
D. By rewarding only half of the dogs touching the screen.
2.Which of the following statements is TRUE about the dogs in the study?
A. The dogs were not all provided with the entire face.
B. The dogs couldn’t read strangers facial emotions.
C. According to their size,the dogs were given either upper or lower halves.
D. The dogs could make out small changes accompanying facial expressions.
3.The underlined word "trepidation" in Paragraph 5 probably means .
A. curiosity B. horror C. excitement D. doubt
4.How might the results change if the dogs with female owners are shown pictures of male faces?
A. They would be scared away at the sight of the pictures.
B. They found it easy to tell the emotions on the entire face.
C. They could only tell emotions on partial faces rather than on entire faces.
D. They found it hard to tell the moods on the faces of a different gender.

Our children and grandchildren may not have a chance to visit many of the most famous places around the world. War, weather, age, traffic and pollution damage these famous places. Looking after these places often costs more than one country can afford.
In the early 1970s, world governments decided that if they joined together, they would be able to preserve our history. If every country paid some money, they said, it would be possible to look after important historic places. Also, if they discovered that a monument needed urgent help, they would have money for repairs. For these reasons, countries around the world united to form the World Heritage Organization in 1972. Today, the organization helps to maintain and restore the most important places from our history.
However, one of the biggest problems for historic places is vandalism. People sometimes enter the sites and destroy or damage the buildings. At some sites, such as Stonehenge(巨石陣)in England, governments have built high fences to protect the site from vandals.
There are many different ideas about how to solve the problem of vandalism. Stone experts say that if guards patrolled the sites, vandals would not be able to get in. Some experts say that if they fixed more television cameras, they would not need so many guards. Other experts say that the best solution is education. If people learned to respect history, they would not destroy or damage it. They would also want to spend money looking after old places. For this reason, the World Heritage Organization helps to spread information about the value of historic sites.
1.Why did countries all over the world unite to form the World Heritage Organization?
A. It would be able to keep our history.
B. It would be possible to take care of important historic places.
C. They would have money to do some repairs if a monument needed help.
D. All of the above.
2.Which of the following shows us the action of vandalism?
A. People enter the sites and cause damage to the buildings
B. Governments build high fences to protect the site from vandals
C. Guards patrolled the sites and they fixed more television cameras
D. They collect as much money as they can to preserve the buildings
3.What’s the best way to solve the biggest problem of preserving our history?
A. Every country spends more money looking after these places
B. To form the World Heritage Organization
C. Too many guards are needed to prevent vandals getting in
D. To make people know more about the value of historic sites
