Dogs can be worried and pessimistic just like people, researchers report in a new study in Current Biology. And they aren’t talking about basset hounds (短脚猎狗): those dogs just look as if they expect the worst.

What the scientists say is that dogs that exhibit anxiety when left home alone by their owners may have bigger problems - they may be in a permanent bad mood.

This pessimistic outlook may not otherwise be easily apparent in a dog’s other characteristics, like running speed or learning ability, the study reports.

Dogs are similar to humans in the role that emotional state plays in decision making, said Michael Mendel, a veterinary scientist at the University of Bristol and the study’s lead author. The study’s researchers looked at 24 dogs in shelters in Britain.

They placed the dogs in isolated settings and observed their reactions - many barked, jumped on furniture and scratched at the door.

Then they placed bowls in two rooms. One bowl contained food, while another was empty. After training the dogs to understand that bowls can sometimes be empty, and sometimes full, they began to place bowls in ambiguous locations.

Dogs that quickly raced to the locations were more optimistic, and in search of food. Those that did not were deemed pessimistic.

The more separation anxiety a dog expressed while in isolation, the more likely the dog was to have a pessimistic reaction, the researchers found.

The study carries an important message for dog owners, Dr. Mendel said.

Dogs that express serious anxiety when alone may need treatment, as it could be a sign of unhappiness and instability.

答案：43-46 DAA B

D

On my first trip in the United States , I went to San Antonion . I was on foot . So I went to only three places there : the Alamo , the River Walk , and the Art Gallery . I especially enjoyed visiting the Alamo , a well- known building in America .

When I arrived at the Alamo , I was deeply impressed because it was well kept and in good shape . The Alamo was erected in about 1722, was later used as a fort(保垒) , and has been kept as a state monument(纪念馆) to the Texan War of Independence against Mexico . During the battle , all of the Texan defenders were killed . I was surprised at the exhibition of rifles , guns , cannons and swords .

I was especially attracted by the paintings of a war . The paintings expressed the feelings of a painter very well . Even thought about 160 years have passed since the Battle of the Alamo , the exhibit is well kept . When I came out after seeing the exhibition , I felt as if I had a victory . The outer wall of the Alamo was destroyed here and there . When I touched the wall , I could feel the damage . After the war , little remained of the Alamo . All of the windows and doors were destroyed . The top part of the gate way disappeared without a trace(遗迹) . I will remember the Alamo forever . It is one of the best places to visit in San Antonio .
