Pete took his seat this day on his usual bench in Union Square．Every Thanksgiving Day for nine years Pete had taken this same seat exactly at one o'clock, and each time the same pleasant thing had happened．But this time Pete had come here more from habit than from hunger．Certainly today Pete was not hungry．Two rich old ladies gave him a Thanksgiving dinner of everything he could eat．

Pete sat on the bench now, hardly able to move．The buttons on his ragged shirt and coat were about to burst．The November breeze and the first light fall of snow felt cool and pleasant to his face．He happened to look to the left and there in the distance he saw the old Gentleman coming toward him．He wanted to get up and run, but he was so full of food he stayed right there．Every Thanksgiving Day for nine years, the Old Gentleman had come there, found Pete on this same bench, and then taken him to a restaurant and bought him a Thanksgiving dinner．It was a kind of tradition which the Old Gentleman, who had no family and lived alone, had tried to continue．

"How do you do' "said the Old Gentleman．" Glad to see that the changes of another year have permitted you to move in health through this beautiful world．"

Each time the Old Gentleman had said exactly this same thin? It was part of the tradition．Pete, too, began to feel as though he himself was now a part of the tradition, and he therefore did not have the courage to tell the old man that he had already eaten．This dinner seemed to mean so much to the Old Gentleman.

"Thank you, sir, " said Pete at last. “I’ll go with you gladly. I’m very hungry, sir.” Together the Old Gentleman and Pete walked south to the same restaurant where each year Pete had his Thanksgiving dinner. The Old Gentleman seemed pleased and happy. When the waiter brought dish after dish of food to Pete, the Old Gentlenman sat quietly and smiled．Under the circumstances, Pete had to eat．It was part of the tradition, and so he ate like a hero, although when he entered the restaurant even the smell of food almost made him sick．At last Pete leaned back with the battle won．

" Thank you, sir, " he said, with some effort, " for a fine dinner．"

They parted as they did each year at the door, the Old Gentlemen going south, Pete north．

Around the corner, Pete stopped for a moment, felt a terrible pain in his stomach, and then fell to the sidewalk unconscious．A little time later an ambulance came．In the hospital they discovered that he had had an attack of indigestion （消化不良）.

An hour later, another ambulance brought the Old Gentleman to the same hospital．At first they thought it was also indigestion but later one of the nurses said, "That nice old gentleman over there—you wouldn't think that it was a case of hunger．"

For several years, scientists have been testing a substance called interferon(干扰素), a possible wonder drug that is proving to be effective in treating a variety of diseases, including virus infections, bacterial infections, and cancers. To date, the new drug has no side effect of great influence to discourage its use. But in spite of its success, last year only one gram was produced in the entire world.

The reason for the shortage lies in the structure of interferon. A special protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so effective that the amount given to each patient each time is very small.

Unlike antibiotics (抗生素), interferon does not attack germs directly. Instead, it protects healthy cells from being infected, and prevents the reproduction of viruses within cells.

As you might conclude, one of the most special uses of interferon has been in the treatment of cancer. Dr. Hans Strander, a research physician at Sweden’s famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who had received operations for advanced cancer, half were given traditional treatments and the other half were given interferon. Among those treated with interferon 70 percent of them remained alive over three years, as compared with only 10 to 30 percent among those who had received the traditional treatments.

In the United States, a large-scale project supported by the American Cancer Society is now under way. If the experiment were successful, interferon could become one of the greatest medical discoveries of our time.

1.What is the difference between antibiotics and interferon?

A. Interferon has serious side effects, while antibiotics do not.

B. Antibiotics kill germs by attacking them directly, while interferon does not.

C. Antibiotics are very effective, while the effect of interferon is limited.

D. They are different in structure, although they are both proteins.

2. According to the passage, if 170 cancer patients received interferon treatment, how many of them would remain alive over three years?

A. About 30.

B. About 50.

C. About 120.

D. About 70.

3. The passage tells us that ________.

A. it is difficult to produce interferon in large quantities because of its special structure.

B. interferon is produced widely in lots of countries.

C. few of the patients who had received traditional treatments remained alive.

D. most of the patients who received interferon also needed traditional treatments.

认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

注意：每个空格只填1个单词。请将答案写在答题卡相应题号的横线上。

The most serious health problem in the world used to be infectious(传染的)diseases such as typhoid fever, flu, bubonic plague(黑死病). In the 14^th century, for example, bubonic plague killed roughly one-third of the population of Asia and about half of the population of Europe. A flu epidemic（流行病） in 1918 killed millions of people around the world. Today, however, vaccines and antibiotics have prevented the spread of many serious diseases. In fact, in many parts of the world today, infectious diseases are no longer considered to be the most serious health problem. In the United States, the number one health problem is the new epidemic of obesity.

What does it mean to be obese? Most doctors and researchers use the body mass index（指数）, or BMI, to determine whether someone is overweight or obese. The BMI equals a person’s weight in kilograms divided by the square of the person’s height in meters. A normal BMI is between 18.5 and 24.9. a person with a BMI of 25.0 to 29.9 is considered to be overweight, while a person with a BMI of 30 or above is said to be obese.

What is causing the epidemic of obesity? One obvious contributing factor is the sedentary lifestyle that many people in the 21^st century are leading. Getting around by car and working at a desk don’t demand much physical activity.

A second cause of obesity epidemic is an increase in the availability and consumption of junk food. The Centers for Disease Control and Prevention defines junk foods as “foods which provide calories primarily through fats or added sugars and have minimal amounts of vitamins and minerals.” Studies have shown that people are consuming a lot more calories daily than they used to, and they are consuming many of those calories outside of regular meals.

The popularity of fast-food restaurants over the past 30 years has also contributed to be the obesity epidemic. The goal of most fast-food restaurants is to make high profits by producing meals cheaply and efficiently, with little concern for the nutritional content of food. As a result, much of the food served in fast-food restaurants is high in saturated fats, sodium, and sugar. The “great taste” of the food comes from artificial flavorings(调味品) created in science laboratories. For example, roughly 50 artificial ingredients are used to make strawberry milkshake sold in one popular fast-food restaurant. High-quality meat has been replaced by low-quality meat that is full of preservatives to make it taste good. While the nutritional content of much fast food is declining, the serving sizes have been getting larger, encouraging people to consume more calories.
