Even as Google plans to test its fleet（车队）of self-driving cars on public roads this summer, its business model remains a bit of a mystery. By 2025, as many as 250,000 self-driving vehicles could be sold each year globally, according to a study by an industry research firm.

"Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people," said Chris Urmson, director of Google's self-driving car project. For now, Google has no plans to sell any of its self-driving cars. They are strictly for research. But they will hit public roads this summer near Google's headquarters in Mountain View, California. Previous testing has taken place only on closed courses.

The cars are built to operate without a steering wheel, accelerator（油门）or brake pedal. "Our software and sensors do all the work," Urmson said. "The vehicles will be very basic—we want to learn from them and adapt them as quickly as possible—but they will take you where you want to go at the push of a button." The prototype（雏形）are the first of a 100-car fleet the tech giant is building.

In the long run, Urmson sees a future of safer roads—the majority of auto accidents are caused by human error—and fewer traffic jams. Robotic cars could also shuttle people who can't drive because of age or illness.

Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own. The company has already tested other types of self-driving cars on public streets, including modified Lexus sport-utility vehicles, under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls.

The state has issued six other companies permits to operate such cars, including Delphi, Mercedes-Benz, Volkswagen, Tesla, Bosch and Nissan. The vehicles that will be tested on open roads this summer will have removable steering wheels, accelerators and brake pedals to allow "safety drivers" to take control if needed.

Google says the cars are safe. The vehicles have sensors that "can detect objects out to a distance of more than two football fields in all directions, which is especially helpful on busy streets with lots of intersections," Urmson said. "We're looking forward to learning how the community understands and interacts with the vehicles, and to uncovering challenges that are unique to a fully self-driving vehicle," Urmson said.

A. will probably decrease traffic jams

The Calgary Public Library has some great resources to beat boredom and keep your children busy over the summer, whether at home or on the road．

Not only is reading a pleasurable way to pass the time, it will also help children keep their skills up over the summer, so they are prepared to go back to school in the fall．

If you are taking a trip this summer, why not let the kids help out with the planning? Borrow a children’s atlas (地图集) to choose your way together and check out some books about your destination before departure.

Some individuals are born with a gift for public speaking.1.Do you want to be a good public speaker? Here are some principles you must master.

People want to listen to someone who is interesting, relaxed and comfortable. Too often when you stand up to give a speech, you focus on the “public”at the expense of the”speaking. “ 2. Focus on the speaking. Talk directly to your audience, be yourself and make a connection.

Even the most successful public speaker will make mistakes. Yet, the only one who cares about any mistake is the one who is speaking. People’s attention wanders constantly. In fact,most people only absorb about 20 percent of a speaker’s message. So, don’t stop speaking when you make a mistake unless it’s a truly serious one.3.

Your goal is not to be a perfect public speaker.4.And like everything else in life, that takes practice. Remember, even world champion athletes practice their skills on a consistent basis.

5.It’s rare to hear someone say, “I wish that speaker had spoken longer. “On the other hand, you probably can’t count the times that you’ve thought, “I’m glad that talk is over. It seemed to go on forever! “So surprise your audience. Always make your presentation just a bit shorter than anticipated. It’s better to leave your listeners wishing for more than shifting restlessly in their seats waiting for your speech finally to end.

A.Do the opposite.

B.You want to be an effective public speaker.

C.You don’ t need to apologize for a minor slip.

D.When it comes to public speaking, less is usually more.

E.The objective of most speeches is to benefit the audience

F.Take the fear out of public speaking by focusing on your listeners

G.However, the majority of people are effective speakers because they train to be.

iPhone owners are vainer (虚荣) and spend more on clothes and grooming(仪容) than those who have BlackBerrys and Android phones, new research claims.

BlackBerry owners earn the most and are more likely to have long-term relationships, while people with Android handsets are most creative and the best cooks.

The study, carried out by TalkTalk Mobile, surveyed 2,000 owners of the three major smartphone brands to determine whether the choice of handset was an extension(延伸) of their personality. The study rated users in various walks of life using a point scoring system including personalities, daily habits and the type of industries they work in.

Other results from the study found that people with an iPhone are more image conscious and generally rate themselves more attractive than those with other handsets. They are most likely to describe themselves as adventurous, bright and are most likely to work in media, publishing and education. They also believe their boss rates them highly. Apple owners also tend to have done more travelling and are the most active on social media sites.

BlackBerry owners were found to be the least punctual(准时的) ,but despite putting in the least hours at work they are the most active phone user—sending more texts and making more calls in the average day than any other phone user. They are more social and have more friends overall. They also earn nearly two and a half thousand pounds a year more than other smarphone owners, with an average salary of $27,406. BlackBerry users classed themselves so loud and mainly work in the health, finance or property sectors. They were also found to drink more tea and coffee each day than any other phone user.

Android owners were found to watch more TV than others and drink the most alcohol—consuming more in an average week than iPhone and BlackBerry drinkers. They have the most jobs in engineering, the government and public services and environmental services. They have the best manners and are more shy and relaxed than their counterparts.

Dan Meader, Director of Mobile at TalkTalk, said, “Many of us have our mobile phones on us almost constantly so they do become an extension of us in many ways. It’s interesting to see then how the choice in handset may reflect different aspects of personality and the results do show some unusual differences.”

1.What do we know about BlaceBerry users?

A. They work latest.                        B. They drink most alcohol.

C. They are the highest earners.            D. They are values most by their bosses.

There are a growing number of pet owners who feed their pets on raw, which means, “uncooked” meat and bones.　 William Burk, a pet food specialist from the Food and Drug Administration （FDA）, believes that feeding raw meat to pets is against its goal of protecting the public from health dangers, and that raw meat and bones do not have all the required nutrition that a pet needs every day.

Recognizing how popular these foods are, the FDA has provided guidelines for producers of pet foods which contain uncooked meat for dogs, cats and other pets. The guidelines give rules to protect pet owners and pets from dangers about food safety and lack of nutrition.

Pet owners who feed raw meat and bones to their pets should deal with these products very carefully to protect themselves against possible dangers, says Burk.　 Just as when you are preparing foods for human beings, use hot water and soap to wash your hands, containers, and surfaces that come into contact with the food. Don’t put your hands near your mouth until you have washed them, and don’t allow your pet to touch your face right after it has eaten raw meat.

“If pet owners choose to feed bones to their pets, they should watch their pets carefully when they are eating bones,” Burk says. “If a pet eats a big piece of bone that won’t pass through its digestive system（消化系统）, it is likely to kill the pet.”

1.What does William Burk think of feeding pets on raw meat?

A. It’ll make the pet owners sick.

B. It’ll keep the pets’ wild nature.

C. It’s against the policy of tile FDA.

D. It’s dangerous and lack of nutrition.

2.The FDA has provided guidelines for producers of pet foods with raw meat because ________.

A. pet safety is a serious problem

B. most pets are lack of nutrition

C. feeding pets on raw is popular

D. the quality of pet foods is dropping

3. Those who feed pets on raw should do some necessary cleaning when ________.

A. preparing raw meat for pets

B. touching the food containers

C. taking their pets out for a walk

D. preparing foods for human beings

4.What suggestion is given to pet owners in the last paragraph?

A. Pets should be forbidden to eat raw bones.

B. Pets should be kept away from the raw meat.

C. Pets should be checked on their digestive system.

D. Pets should be watched carefully while eating bones.
