     Do dogs understand us?
     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 the 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 (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!

Do you have a sore throat, a running nose and a headache? Do you keep coughing and sneezing? If you do, the chances are that you have a cold or perhaps flu---but which one? Although both colds and flu are caused by viruses, they are very different illnesses.

Colds, which usually last about a week, affect the nose most. They commonly cause a running nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.

Flu is a much more serious illness and is caused by different groups of viruses. People with flu usually get all the symptoms(症状) described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the characteristic symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.

Flu can be a deadly disease. The elderly(年长的), who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection(预防针) before the start of winter when flu is most common. This injection is inexpensive and definitely（明显地）worth it.

If you have a cold or flu, you must always deal with used tissues(手巾纸) carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze! You don’t want to see the small drops of liquids blown(喷) out of your nose and mouth when you sneeze, do you? Disgusting(令人作呕), eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!

In paragraph 4, we learn that ________.

A. flu injection can cause death B. most old people die from flu

C. flu can kill old people easily D. flu is most common in summer

Dealing with used tissues properly(正确地) is important because ________.

A. it helps keep your classroom tidy B. it prevents the spread of colds and flu

C. people hate picking up dirty tissues D. picking up lots of tissues is hard work

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

A. Both colds and flu last the same time.

B. Both colds and flu can be prevented by injection.

C. Both colds and flu are caused by the same viruses.

D. Both colds and flu have an aching symptom.

Which is probably the best title for the passage?

A. Colds and Flu B. The Different Symptoms of a Cold and Flu

C. Prevention Is Better Than Cure

D. Cover Your Nose and Mouth When Sneezing
