At midnight Mr. King coughed again. He got up and took some medicine. Before he lay down again, he smoked. And he couldn't go to sleep any longer. He found the medicine book and began to read it. He was afraid he had lung(肺) cancer (癌). He seemed to see death was waiting for him. Tears(眼泪) ran down his face. He didn't see his wife was standing by him.

    “What's wrong with you, dear?” asked the woman.

    “Nothing,” the old man answered and covered his face with his hands.

    The old woman opened the book and understood at once. She said, “You must stop smoking right now.”

    “I began to smoke when I was nine, you know. How can't I do that?”

    “But I think health is more important.”

    Mr. King coughed again and his wife said, “Go to see a doctor tomorrow. He will be able to help you, I think.”

    The doctor told Mr. King to have an Xray examination(检查) of his lungs. And then he looked at the Xray carefully for a long time.

    “Tell me the truth, doctor.” said Mr.King, “Do you see any shadows(阴影)in my lungs?”

    “No, I don't see anything.”

    “Yes?” the old man said happily. “Really?”

    “Yes. Your lungs are turning black. How can I see any shadows?”

    Billy Dengler, a 14-year-old boy, is in the eighth grade. When he was born a month later, Billy's mother, Terri, noticed that his eyes weren't quite as big as a normal baby's. She took Billy to the hospital, and the doctor said Billy would never be able to see.

    Although Billy can't see, he has never let that hold him back or make him different. Billy began teaching himself computer programming by using a screen reader when he was just seven years old. He is a certified Google developer (谷歌认证开发者) now. Google even tried to offer him a job last year when he discovered a problem in one of its systems, but Billy wasn't old enough.

    Billy's dream school would be Stanford University or MIT, where he could get a very good education in computer science. After he leaves school, whether he will go to work at a company like Google or design a software company of his own is still to be decided. However, he says he will definitely (绝对地) do something great.

    "It's a sighted world," Billy said. "You can't let anything get in the way of your dreams, and if you do that, you can't move forward and make your dreams come true."

    Today was quite an amazing day for me. It was the day that my father returned home from Russia. He had been away from us for over a year. I had missed him more than words could ever say. Although we were proud of him, we hoped that he could wake up under the same roof (屋顶) as us. Now the day had finally arrived. He had worked hard and it was now time for him to return home.

    Mom woke us at 6 a.m. to go to the airport. My father's flight (航班) was due to arrive at 9:30. “We don't want to be late!” she kept saying as she woke everyone up. She had no need to remind me! I quickly dressed, washed and had breakfast. I could not take my eyes off the clock all morning. Time was going so slowly. When it was 8:45, my mom told us all it was time to go. We all ran to the car and made our way quickly to the airport.

    We arrived just after 9 and waited patiently. But 9:30 came and went and our father's flight had still not arrived. I kept asking Mom where he was. She just kept smiling and saying he'd be there soon. Another 10 minutes went by, and suddenly a tall man appeared in the crowd. There was my father standing before me. He dropped his bags to the floor and hugged my sister and me. “I've missed you so much,” he said. We all cried together. I never want my father to be away for such a long time.

    Today was pretty perfect.

B

    Most of us have ever imagined the life on a desert island. We sometimes imagine a desert island to be a sort of paradise(天堂) where the sun always shines. “Ripe fruit falls from the trees and you are free to sit around without any work. This is really a beautiful picture, isn't it? However, the other side of the picture is quite the opposite. Life on a desert island is awful. You either starve to death or live like Robinson Crusoe, waiting for a boat which never comes.

    Perhaps there is some truth in both these pictures, but few of us have had the chance to find out. We can only experience it in the story like the following.

    Many years ago, two men spent five days on a coral island and they wished that they could stay there longer. They were driving a badly damaged boat from the Virgin Islands to Miami to have it repaired. During the journey, their boat began to sink(下沉). They quickly put food, matches, and cans of beer into a rubber dinghy(救生筏) and rowed for a few miles across the Caribbean until they arrived at a tiny coral island.

    There were hardly any trees on the island and there was no water, but this did not seem to be a problem. The men collected rainwater in the rubber dinghy. As they had brought a gun with them, they had plenty to eat. They caught lobster and fish every day, and they thought they lived just like a king. Five days later, a tank passed by and saved them. However, they felt sorry that they had to leave
