Be careful what you say around your dog. It might understand more than you think.

A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).

In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.

In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.

The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked

out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          

Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.

It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

As we all know sewing-machine(缝纫机) repair is one of the fastest growing businesses in the world today. Newspapers, women’s magazines, high schools and colleges are all encouraging millions of American women to do their own sewing, not only to make their own shirts and sweaters, but also to make nice clothes for their husbands, sons, or boyfriends. The lattes figures(数字) show that over 89 million American women, because of the high costs of ready-to-wear clothing are now making almost all of their families’ clothes. Most of these women get great satisfaction from making the family clothes on their own sewing machines. So it is natural that the demand(要求) for excellent service of sewing machines is growing.

Think of it! 89 million or more sewing machines, not including another 10 million sewing machines in schools of all kinds, need service at least once a year, and quite possibly four or more times each year. I know some women who return their sewing machines to repairmen time after time to get them fixed properly. I’ve seen sewing machines come out of repair shops in worse condition than they were when they went in.

So I’ve decided to write an introduction book to sewing-machine repair and teach people how to repair their own sewing machines at home. It’s not that difficult. In the book, I will teach you everything you need to know about how to repair your sewing machine.

  A. they cannot buy the clothes they see in magazines

  B. their husbands or boyfriends want them to do so

We learn from the passage that sewing machines        .

  A. aren’t very difficult to be repaired

  B. cannot work well after one year

  C. don’t easily get broken

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease – especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.

The field of medicine has not traditionally distinguished between someone who is merely “ not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise and they make a point of monitoring their body's condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap may be "well," in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. "Wellness" may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.

Today medical care is placing more stress on______.

    a. keeping people in a healthy physical condition   

b. monitoring patients' body functions

c. removing people's bad living habits            

d. ensuring people's psychological well-being

In the first paragraph, people are reminded that_____.

    a. good health is more than not being ill           

b. drinking, even if not to excess, could be harmful

c. regular health checks are essential to keeping fit  

d. prevention is more difficult than cure

     Traditionally, a person is considered "well" if he ______.

     a. does not have any unhealthy living habits     

b. does not have any physical handicaps

c. is able to handle his daily routines           

d. is free from any kind of disease

According to what the author advocates, which of the following groups of people would be        considered healthy?

a. People who have strong muscles as well as slim figures.

b. People who are not presently experiencing any symptoms of disease

c. People who try to be as possible, regardless of their limitations.

d. People who can recover from illness even without seeking medical care.
