Time is very important in our lives. It organizes our everyday moments. However, time never had any importance in my life until I  16  a watch from my father, which organized my life and made me more responsible. It’s round in the center with two silver bands(带) that   17 around my wrist and all of it is made of silver.

I received this   18 on a gray – sky day. I had to go to the airport at 9:00 am to  19  up my Uncle Ali and take him to my father’s house.  20  , I was late because I was   21 out with my friends. Later on that day, around 11:00 am, I   22 my uncle, but I was very late for him. He had   23 the airport and taken a taxi to my father’s house.

I got to my father’s house at 2:00 pm that day and felt ashamed of myself at that moment. After I said hi to my   24 father and tired uncle, my father asked me to sit next to him and handed me this watch as a gift from him. Then he said, “Peter, did you have   25 with your friends today?” I answered, “Yes, father, and   26  apologized for not meeting my Uncle Ali.” He said, “What you   27  was not very nice and you should be sorry for your action.” I was ashamed and said, “Father, I’ll never do it again . I promise.” He said, “I hope today you learned something important, and this watch will be a   28  for you.” He told me to take this watch and use it as an organizer of my  29  .

I learned a very important lesson from my father: to respect time and never to be late to get someone. This watch is   30  to me, not because of its price, but because of the lesson that I learned from it.

One in 400 children in the United States has diabetes(糖尿病). And the most difficult thing for the young diabetic patients is that many of them don’t have a clear idea when they need to take insulin(a drug used in treating diabetes).The parents of one Long Island boy found the perfect solution—Hero, a specially trained dog that can discover when a diabetic is in trouble and find help.

Johnny Pion, eight years old, is a poor kid that was told he was a diabetic in 2008. He can’t do without insulin. His blood-sugar levels should be closely checked. He even can’t go out to play without his mom or dad fearing he might need help.

With Hero in her new home, Johnny’s parents may worry a little less. They received the news about Hero on the newspaper. The dog cost around $20,000. With the help of friends and family, the Pions brought Hero home from Warren Retrievers in Virginia. Mary Campbell. Hero’s trainer, said the dog could discover the slightest changes in blood sugar by her sense of smell.“Humans have 5 million smell receptors(感受器)； dogs have 5 billion smell receptors,”she said.

When the dog discovers something’s wrong, she’ll rub(蹭)her head against Johnny’s legs. If he doesn’t answer her, Hero knows to look for Johnny’s mom and dad. Hero even could ring up 911.

On their first night, Johnny’s was comfortably sleeping in his own bed with Hero and not with his parents for the first time. Night time is very important because blood sugar goes unchecked while sleeping. Now Hero is a round-the-clock nurse.

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.
