A doctor entered the hospital hurriedly after being called in for an important surgery（外科手术）. He found the boy's father in the hall waiting worriedly.

On seeing him, the father cried out. "Why did you take all this time to come? Don't you know that my son is in danger? Don't you have any sense of duty?"

The doctor smiled and said, "I am sorry. I wasn't in the hospital and I came as fast as I could after receiving the call and now. I wish you'd calm down so that I can do my work."

"Calm down? What if your son was in this room right now? Would you calm down? If your own son dies while for a doctor, then what will you do?" said the father angrily. The doctor smiled again and replied. "We will do our best and you should also pray for your son's healthy life."

The surgery took some hours after which the doctor went out happily. "Thank goodness! Your son is saved!" And without waiting for the father's reply he carried on his way running by saying, "If you have any questions, ask the nurse."

"Couldn't he wait some minutes so that I can ask about my son's state?" shouted the father when seeing the nurse minutes after the doctor left.

The nurse answered tears coming down her face. "His son died yesterday in a road accident. He was at the burial when we called him for your son's surgery. And now that he saved you son's life, he left running to finish his son's burial."

"A cold can disappear in two days. Seventy percent of people who catch a cold feel better within a week, but it is unusual to have the common cold for as long as two weeks," says Gary Rogg, a medicine specialist（专家）at Montefiore Medical Center in New York

Why does your cold seem to be staying for longer than it should? Here are some possible reasons.

Getting Less Sleep

Sleep plays an important role in our system. In fact, a study proved that people who got less than seven hours of sleep per night were nearly three times more likely to catch a cold than people who slept for eight hours or more.

Drinking less water

Water plays an important part in your body. If your cold won't go away, consider drinking more water.

Treating the Wrong Illness

The common cold sat easily be mixed with other illnesses. Often, people believe they've had a cold for a few weeks and may not realize that they aren't getting better because they've been treating the wrong illness.

Exercising Too Hard

"People ask me all the time." Should I exercise when I have a cold?" Katona says. "My answer is usually 'yes', but do it at a lower level. If you do it at a high level, you may get even worse."

What does Katona consider to be a lower level? The answer is taking a walk, not running five miles.

Sometimes I really doubt whether there is love between my parents. Every day they are very busy trying to make money for my schooling.

One day, my mother was sewing（缝）a quilt. I silently sat beside her.

"Mum, is there love between you and Dad?" I asked in a very low voice.

With surprise in her eyes, she stopped her work for a while. Then she said, "Susan, look at this thread（线）. It can hardly be seen, but it's really there. It makes the quilt strong. If life is a quilt, love should be a thread. Love is inside."

I couldn't understand her until the next spring. At that time, my father suddenly got sick seriously. My mother had to stay with him in the hospital for a month.

After they were back, my mother helped my father walk slowly on the country road every day. They were so kind to each other and it seemed that they were the happiest couple.

After two months my father still couldn't walk by himself.

"Dad, how are you feeling now?" I asked him one day.

"Susan, don't worry about me," he said. "I just like walking with your mum. I like this kind of life." Reading his eyes, I knew he loves my mother deeply.

Now I understand that love is just a thread in the quilt of our life. Love is inside, making life strong and warm.

A group of young people, who had succeeded in their work, got together to visit their old university professor. Their conversation soon turned to complaining (抱怨) about the stress in work and life. The teacher went to the kitchen and returned with a large pot of coffee and many cups. Some of the cups are expensive and lovely, but some are cheap and not beautiful. The teacher told them to help themselves to the coffee.

When all the students had a cup of coffee in hand, the teacher said, "Have you noticed all the nice looking expensive cups were taken, leaving behind the cheap ones? It's OK for you to want only the best for yourselves, but that is why you have the stress in your work and life even if you're very successful now. What all of you really wanted, was coffee, not the cups, but you choose the best cups and were eyeing others cups."

"Now think about the life is the coffee, and the jobs, money and position in society are the cups. They are just tools to hold life. They do not change the quality (质量) of life. Sometimes, we just care about the cups, and we fail to enjoy the coffee. So, don't let the cups drive you; enjoy the coffee instead."

Friends play a very important part in everyone's life. Friendship usually develops during childhood. New friends are made when you progress through school. Those friends that you make as a student can usually last long. Friends influence your development, maturity (成熟) and sense of responsibility. A familiar expression is "You can tell a lot about a person by knowing who his friends are."

Friendship is based on common interests. If you like sports, most of your friend are likely to be athletic (竞技的). If you enjoy reading and shopping, most of your friends do the same.

Some people call you're their friends for the wrong reasons. These people are not really friends. They are only "superficial (表面上的) friends" on the outside, not the inside where it counts. Superficial friends only want to be your friends if it is to their advantages. True friends are there if you are rich or poor. It is easy to have many so-called "friends" if you are rich. By this time you should be able to separated (分开) your friends into the real or the "phoney".

True friends are most special. They are also difficult to find. You can consider yourself very lucky if you have one true friend. This friend is eager (渴望) to help you whenever necessary. He or she knows you would do the same for them. A true friend is someone you can talk to about any subject or problem. You and your true friends have good understanding of each other. True friends support you, take your side, and built up your confidence.

When I started working at Xinhua High School three years ago, I was     41       (introduce) to Gina Smith, the school's headmistress.

Her smart appearance and warm, friendly expression made me like her at     42    . She is a small-boned, smiling lady in her early fifties. She has     43       (shine) blue eyes and soft silver hair. She is a very fair-minded person who     44       (treat) everyone at the school in the same way. Even when she is upset, she is actually very calm, which is shown by her ability to control her     45       (feel) in the most difficult situations. Her quiet voice and gentle, polite manner make her popular w    46    the children.

Ms. Smith has no children of     47       (she) own, however, she says that she feels like a mother to all of the children in her school. Besides     48       (deal) with different leading tasks every day, she always spends time talking to the teachers and parents     49       (patient).

To my mind, Gina smith is an education expert     50    is a wonderful role model, not only for the children but for the teachers as well.
