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.

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 _________.

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.

Scientists have found that human eyes are more likely to be damaged by UV rays while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper.

The researchers at Kanazawa Medical University, Japan and American company Johnson & Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District.

They found that on the beach, eyes are exposed to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered areas.

The findings are supported by the Japan Meteorological (气象的) Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.

Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes.

If your eyes are exposed to large amounts of UV radiation over a short period of time, you may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes.

Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of eye damage, which could lead to total blindness.

1.You would most likely find the article in .

A. a doctor's diary B. a travel journal

C. a medical magazine D. a physics textbook

2.Which of the following statements is TRUE according to the passage?

A. Too much eye exposure to UV rays may cause total blindness.

B. Short-time exposure of the eyes to UV rays doesn't harm them at all.

C. Most people know that UV rays harm the eyes as well as the skin.

D. The study was conducted by researchers from Japan, the USA and the UK.

3.Human eyes are more likely to be damaged by UV rays while skiing in the snow-covered areas than sitting on the beach because .

A. Snow produces more UV light than water.

B. People don’t wear sunscreen while skiing as they do while sitting on the beach.

C. The reflection rate of UV light in snow-covered areas is much higher than that on the beach.

D. Human eyes are exposed longer to UV light in the snow- covered areas than on the beach.

4.What will the passage most probably talk about next?

A. Never ski on newly fallen snow in Japan.

B. Go to hospital to have your eyes examined.

C. Wearing a hat can provide protection while skiing in new snow areas.

D. Take some measures to protect your eyes while skiing in new snow areas.
