So you think you know your dog. But how well does your dog know you? She probably recognizes you when she sees you. But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face? Researchers in Austria have taught pet dogs to know the difference.

Dogs are very mindful of sound. When dog owners shout or speak in a strong, harsh(刺耳的) voice, dogs often act guilty and quietly move away from the area. Researchers have found that dogs can look at our faces, and tell the difference between a smile and a frown. The animals were able to recognize a look of approval from one of disapproval.

Researchers performed a series of experiments. They taught dogs to recognize facial expressions. They showed the dogs two pictures of either the upper of lower half of a person’s face. On one picture, the person looked happy. The other appeared angry. The dogs were then shown images of the eyes or mouths of people they had never seen before. They were also shown the left half of the faces used in training. Once the dogs learned to recognize which image was happy or angry, they could easily identify the same expressions in pictures of any face.

Corsin Muller, who led the study, says future studies will try to show whether dogs can learn the meaning of facial expressions—for example, whether a frown shows that someone is angry. “What we can say with our study is that they can tell these ones are different. But what we cannot be sure of at this point is what exact meaning they are associating with these different expressions.”

“Of course it seems likely that they would associate (联系)some positive meanings with the smiley face and they would associate some rather negative meanings with the angry face. But what exactly they are associating with these expressions we cannot know at this point.” Corsin says.

Neither television nor radio nor magazines nor books nor any other medium can begin to match newspapers for depth and breadth of coverage (新闻报道). In fact, all these media themselves depend on newspapers to bring them information that they then process and distribute as their own brand of news.

Now many newspapers are locked in a struggle for survival. If they lose—which is by no means impossible—we all lose.

The great task for editors and publishers is to respond to the competitive challenge caused by online news, and at the same time use their own online news to increase their profits (利润). As yet，they haven't figured out a smooth and sure way to do that.

So they cut some more to get profit. The cuts in size that they are making are in some cases risky and in others without considering the results. With every cut, publishers tirelessly argue that readers won't even know the difference. The trouble is that by the time customers do notice that they are getting less for their money，it will be too late—too late to notice the reduction in the number of readers.

The other big cuts, of course, are in staff (员工). The victims would be the oldest and most experienced workers because they are the highest paid.While there is plenty of tired deadwood among them，there is also a lot of talent.

When experienced staff leave in large numbers—as they often do now—the newspaper loses great professional memory. But the real loser is the readers, who are suddenly robbed of the insights (见识) that only the experienced reporters can bring.

As for the future, there is at least one big, bright sign：intelligent young people will continue to flood into journalism in urgent search of jobs, despite its high demands and modest (不太高的) pay.

1.The underlined word “deadwood” in Paragraph 5 may refer to “ ”．

A. the staff who are going to retire

B. people who are no longer useful or needed

C. workers who are experienced

D. reporters who are tired of covering events

2.According to the passage，which of the following can best describe the author's attitude towards the ways the editors and publishers have adopted to get profit?

A. The author has no objection.

B. The author is against them.

C. The author has not shown it clearly.

D. The author regards them reasonable.

3.The author seems to agree with the view that .

A. experienced workers are the last to be laid off

B. journalism is a job offering highest pay for high demands

C. the challenge of newspapers is that there are not enough intelligent young people

D. it is possible that newspapers may not survive in the end

4.It is stressed by the passage that the most important quality for a journalist is .

A. patience B. selfishness C. insights D. sensitivity

Loch Ness, the largest freshwater lake in the British Isles, is twenty four miles long and, at one point, one mile wide. It has an average depth of four hundred and fifty feet and at times drops close to a thousand. It is cold and murky(浑浊的), with dangerous currents. In short, it is the perfect place to hide a monster from even the sharpest eyes of science.

The Loch Ness Monster, also called Nessie, is supposedly living in this area. The earliest recorded sighting of the Loch Ness Monster was in the biography of Life of St. Columba by Adamnan in the year AD 565. The monster apparently attacked a man who was swimming in the River Ness.

The monster didn’t make headlines again until August 27, 1930, when 3 fishermen reported seeing a creature with 20 feet long approaching their boat, throwing water in the air. In 1933, after a new road was built along the edge of the Loch, the number of reports rose suddenly. Early in 1934, Author Grant, a young student, was out on his motorcycle one evening when he almost ran into the monster as it crossed the road. Grant’s description of the thing — small head, long thin neck and tail with a big body, seemed to match the appearance of the plesiosaur(蛇颈龙), an aquatic(水生的) type of dinosaur that has been extinct(已灭绝的)for 65 million years.

The Loch Ness Investigation Bureau was formed in 1962 to act as a research organization for information about the creature. Even now, efforts have continued to find the monster. A great deal of information was discovered about the Loch, but they haven’t yet to produce any specific evidence of a monster.

Skeptics(怀疑论者) argue that the water in the Loch is too cold for a plesiosaur to live in. They also argue that an air-breathing animal, like a whale or seal, would spend much more time on the surface than the creature seems to, and would be spotted more often.

Some scientists have wondered if the sightings might be caused by an underwater wave which is known to sometimes occur in deep, long, and cold lakes, like Loch Ness. Such a wave might push debris(废弃物)to the surface that might look like a strange animal.

However, none of these is identified.

B. The Loch Ness Monster often stays under the water.

Mr. Black was the manager of a hotel in Atlanta. One weekend all of the hotels were full because of a large business meeting being held in the city. On Sunday night, three men came into Mr. Black’s hotel and asked for rooms. Mr. Black told them that there were no more rooms available. The men didn’t know what to do because they had no place to stay in.

Mr. Black wanted to help them. He remembered that there was an empty room at the far end of the first floor — Room 112. It was a very small room, and had rarely been used as a guest room before. So, he asked the three men if they would mind sharing that small room. They replied that they would be very satisfied so long as there was a room for them to stay in for the night.

Mr. Black then told them that the room would cost them $ 30 in total. On hearing this, each of the three men gave Mr. Black $ 10 before they left for their room.

However, Mr. Black soon began to think that $ 30 was really too much for that small room. He called his assistant over and said, “Here is $ 5. Give it back to the three men in Room 112. Each of them paid me $10. That’s too much.”

The assistant took the money. While he was on the way to that small room, he thought, “How can three men divide $ 5? I’ll give each of them only $ 1 and keep the $ 2 left to myself. The men will be happy to get anything back, and I can also make some money that way. After all, Mr. Black will never know anything about it.” So, the assistant returned only $1 to each of the three men.

Each man had first paid $ 10. After the assistant returned $1 to him, each man had actually paid only $ 9. There were three men. $ 9×3=$27. The assistant kept $ 2. $ 27 + $ 2= $ 29. Where is the missing dollar?

1.Why didn’t Mr. Black offer Room 112 to the three men at first?

A. The key had been lost.

B. It was too small for three men.

C. No one had stayed there before.

D. It was not bright enough.

2.How much did Mr. Black first ask each man for the room?

A. $ 30.B. $15. C. $10. D. $9.

3.How were the manager and his assistant in behavior?

A. The manager was honest but the assistant was not.

B. The manager worked hard, but the assistant was lazy.

C. The assistant was clever but the manager was not.

D. The manager did not know how to make money, but the assistant did.

4.Where is the missing dollar?

A. The three men took it.

B. The manager hid it secretly.

C. The assistant kept it.

D. There is no missing dollar.
