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.

　　On May 21, 2000, some American scientists were working at the computers to look for information they needed . Suddenly they saw a lot of very bright red spots crossing the computers’ screens. At the same time the computers were working much slower. To find out what was happening they stopped their work to check some parts of the computers. To their horror, they found out that most of their stored information was got rid of by computer viruses (病毒). Obviously all these computers had been infected by computer viruses.

It is said that the computer viruses were made by two or three Philippine young men fond of playing tricks. They all had excellent education. They created the viruses just to show their intelligence. The kind of computer virus is named I Love You Virus. This virus can hide in computers for long. When the time comes they will attack the computers by lowering the important functions, damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store, what’s worse, it still can reproduce itself in great quantities within a short time.

We come to know that “I Love You” Virus often attacks computers on Mondays and that it is spreading to many computers in the world. Among the countries that suffered computer viruses last year are Britain, Australia, Switzerland and the USA. Those who made the computer muses have been found out slowly and carefully. But till now, how to get rid of the terrible viruses remains a problem.

Would you like to be a king or queen? To have people waiting on you hand and foot? Many Americans experience this royal treatment every day. How? By being customers. The American idea of customer service is to make each customer the center of attention. Need proof? Just listen to the commercials. Most of them sound like the McDonald’s ad: “We do it all for you.” Actually, not all stores in America roll out the red carpet for their customers. But wherever you go, good customer service means making customers feel special.

People going shopping in America can expect to be treated with respect from the very beginning. Most places don’t have a “furniture street” or a “computer road” which allow you to compare prices easily. Instead, people often “let their fingers do the walking” through the store hot lines. From the first “hello”, customers receive a satisfying response to their questions. This initial contact can help them decide where to shop.

When customers get to the store, they are treated as honored guests. Customers don’t usually find store clerks sitting around watching TV or playing cards. Instead, the clerks greet them warmly and offer to help them find what they want. In most stores, the clear signs that label each department make shopping a breeze. Customers usually don’t have to ask how much items cost, since prices are clearly marked. And unless they’re at a flea market or a yard sale, they don’t bother trying to bargain.

When customers are ready to check out, they find the nearest and shortest checkout lane. But as Murphy’s Law would have it, whichever lane they get in, all the other lanes will move faster. Good stores open new checkout lanes when the lanes get too long. Some even offer express lanes for customers with 10 items or less. After they pay for their purchases, customers receive a smile and a warm “thank you” from the clerk. Many stores even allow customers to take their shopping carts out to the parking lot. That way, they don’t have to carry heavy bags out to the car.

By quoting (引用) the McDonald’s ad: “We do it all for you”, the author intends to_______.

A. suggest that customers believe what commercials say deeply

B. show readers the American idea on good customer service

C. express all the stores pay much attention to the customers

D. persuade readers to choose the stores with ads correctly

In the USA, what may you do at first if you want to do some shopping?

A. To visit a professional street with lots of similar stores.

B. To compare prices in many shops in the same street.

C. To make phone calls and get better shopping choices.

D. To receive other customers’ answers to the questions.

The underlined words “a breeze” in Para.3 most probably means _________.

A. an easy job　　 B. a trouble　　           C. a funny thing　　     D. a boring task

Which of the followings shows American stores offer convenience to customers in this passage?

A. The store clerks don’t usually sit around watching TV or playing cards.

B. Some stores offer price bargain to the customers like a yard sale.

C. The clerks give customers a smile and a warm “thank you” after paying.

D. Some stores open new checkout lanes when the lanes are crowded.

Which of the following can be the best title of this passage?

A. Customer Service in America                     B. Excellent Stores in America

C. Shopping Rules in America                           D. Being King or Queen in America

For years experts have argued that poor households are consuming less nourishing food than the rest of the population.

 But a survey of some of the lowest earners in Britain shows the nutritional value of what they eat is little different to everyone else.

 In fact, the same deficiencies in diet were shared by all the population and the findings suggest that poor eating choices are far more widespread than previously suspected - affecting many wealthier families.

 These included low fruit and vegetable consumption, not eating enough oily fish and eating too much saturated fat and sugar.

 “This is a large and significant study and it shows we are all eating just as bad a diet as each other,” said Tim Lang, professor of food policy at City University.

 The poorest families were eating only slightly more sugar and slightly less fruit and vegetables, according to the study of 3,728 respondents in the bottom of the population.

 Alison Tedstone, head of nutritional science at the Food Standard Agency, said: “ Overall, people on low incomes have less than ideal diets, but their diets are only slightly worse than those of the rest of the population.”

 The study also showed that low earners are choosing to eat unhealthily. Their food choices were not linked to their income, their access to shops or their cooking skills.

 The findings appear to contradict assumptions that the poor cannot afford healthier foods or are too far away from shops that sell them.

 The Low Income Nutrition and Diet Survey showed that like the rest of the population, the poor's daily fruit and vegetable intake on average is below the recommended five portions. Fewer than 10 per cent of respondents hit this target, while around 20 per cent ate less than a portion per day.

 More than three quarters (76 per cent) of men and 81 per cent of women did less than one 30-minute session of moderate or vigorous exercise per week.

 Some 45 per cent of men and 40 per cent of women were smokers.

 This compares with 28 per cent of men and 24 per cent of women in the general population.

According to the passage, which of the following is true?

   A. Whether the poor or the rich maybe have a bad diet.

   B. Even the poor can enjoy enough fruit and fish consumption.

   C. Only the poor have a bad diet.

   D. The study was conveyed in both the rich and the poor.

What kind of persons maybe eat most sugar?

   A. The rich.             B. Men.                        C. The poorest.             D. Women

From the passage, we can learn __________.

   A. the poor choose unhealthy food because of low income

   B. having no access to shops also leads to the poor’s bad diet

   C. the poor’s daily fruit intake is as much as general people

   D. the number of smokers in the poor is bigger than that in general people

What’s the best title of the passage?

   A. The poor’s healthy problem.                    B. Keep off junk food.

C. How to have a good diet.                       D. A diet survey.

The True Story of Treasure Island

It was always thought that Treasure Island was the product of Robert Louis Stevenson’s imagination.  ___36___，recent research has found the true story of this exciting work.

Stevenson, a Scotsman, had lived    37    for many years in 1881 he returned to Scotland for a    38    . With him were his American wife Fanny and his son    39     .

Each morning Stevenson would take them out for a long    40    over the hills. They had been   41    this for several days before the weather suddenly took a turn for the worse, Kept indoors by the heavy rain. Lloyd felt the days    42    . To keep the boy happy Robert asked the boy to do some   43   .

One morning, the boy came to Robert with a beautiful map of an island. Robert   44   that the boy had drawn a large cross in the middle of   45   . “What’s that?” he asked “That’s the    46   treasure “said the boy Robert suddenly   47   something of an adventure story in the boy’s   48   While the rain was pouring, Robert sat down by the fire to write a story. He would make the   49    a twelve-year-old boy just like Lloyd.  But who would he the pirate（海盗）?

Robert had a good friend named Henley, who walked around with the   50   of a wooden leg. Robert had always wanted to   51   such a man in a story  52   Long John Silver the pirate with a wooden leg, was   53   .

So thanks to a    54   .September in Scotland a friend with a wooden leg and the imagination of a twelve-year-old boy we have one of the greatest   55   stories in the English language.
