There was once a captain who loved money so much that he cheated his sailors at the end of every voyage and took their wages.

    On the last day of one voyage, the ship was in a small port. It was winter time, and the sea was very cold, so the captain said to his sailors, "If one of you stays in the water during the whole night, I will give him my ship. But if he comes out before the sun appears, I shall get his wages."

    The sailors had heard about the captain's cheating, so they didn't trust him. But then one of them, who thought that he was cleverer than the captain, said that he would do it. He got into the water, and, though it was very cold, he stayed in it. When it was nearly morning, some fishermen lit a fire on the shore about half a mile away.

    "You are cheating," the captain said to the sailor. "The fire's warming you."

    "But it's half a mile away!" said the sailor.

    "A fire's fire," answered the captain. "I have won."

    The sailor came out of the water, and said, "Perhaps you think that you are clever because you have won my wages, but you can't cook a chicken."

    "I can," answered the captain.

    "If you cook this chicken," said the sailor, "I shall work for you without wages for seven years, but if you can't, you will give me your ship."

    The captain agreed, took the chicken and said, "Where's the fire?"

    "There it is," answered the sailor. "On the shore."

    "But it's half a mile away," said the captain angrily.

    " A fire's fire, you said," answered the sailor. "If it is enough to warm me in the water, it is enough to cook your chicken."

    Tu Youyou, an 84-year-old female scientist, became the first Chinese to win a Nobel Prize in science on Oct 5. Before that, she ever won the 2011 Lasker Award for finding out artemisinin (Qinghaosu), which saved millions of lives. She was thankful for the Lasker prize, but said, “It is just a scientist' duty. I will go on fighting for the health of all humans.”

    Tu kept her work in the 1960s and 1970s. In that age, Malaria could took away people's health. Scientists all over the world had already tried over 240 000 times but failed. Tu Youyou, a member of the Academy of Traditional Chinese Medicine, Beijing, began to study Chinese herbs.

    Before 2011, people didn't know Tu very much. Many friends played jokes with her “the Professor of Three None's” : no degree, no study experience abroad, not a member of any Chinese national colleges. But she is hard-working. She read a lot of traditional Chinese medicine books and did a lot of researches on the disease.

    In February, 2012, Tu was named National Outstanding Females (One of the Ten) Tu is now a model of Chinese medical workers.

    At thirteen, I was diagnosed with kind of attention disorder. It made school difficult for me. When people else in the class was focusing on tasks, I could not.

    In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hard right away and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it.” She glanced down at me through her glasses, "you are no different from your classmates, young man.”

    I tried, but I didn't finish the reading when the bell rang. I had to take it home.

    In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots（点）,which opened up a whole new world of knowledge to the blind.

    Wasn't I the “blind” in my class, being made to learn like the “sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?

    I didn't expect anything when I handled in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day-with an “A” on it. At the bottom of the paper were these words: "See what you can do when you keep trying?”

    As I begin to tell my friends about the seven days you treated my wife, Laura, in what turned out to be the last days of her young life, they stop me at about the 15th name that I recall. The list includes the doctors, nurses, social workers, and even cleaning staff members who cared for her.

     “How do you remember any of their names?” they ask.

     “How could I not?” I respond.

    Every single one of you treated Laura with such professionalism and kindness and dignity as she lay unconscious. When she needed shots, you apologized that it was going to hurt a little, whether or not she could hear. When you listened to her heart and lungs through your stethoscopes(听诊器)and her gown (长衫)began to slip, you pulled it up to respectfully cover her. You spread a blanket when the room was just a little cold and you thought she'd sleep more comfortably that way.

    You cared so greatly for her parents, helping them climb into the room's awkward recliner(躺椅), fetching them fresh water almost by the hour, and answering every one of their medical questions with patience.

    Then there was how you treated me. How many times did you walk into the room to find me sobbing, my head down and resting on her hand, and quietly go about your task, as if willing yourselves invisible? How many times did you help me set up the recliner as close as possible to her bedside? How many times did you check on me to see whether I needed anything, from food to drink, from fresh clothes to a hot shower.

    Really, I have all of you to thank for it with my eternal gratitude and love.

Research shows that isolation(隔绝，孤立)is bad for us and associated with certain diseases including depression, high blood pressure and heart disease. Yet teenagers seek isolation by using the device of our times—a screen, screens of all kinds. However, in whatever form, screens are addictive, and addictive from an early age. Research has shown that given the chance, six-month-old babies prefer screens to real human faces.

    Hand in hand with this addiction to screens, we are seeing an explosion of teenage mental health problems. Social media claims to be inclusive, keeping you connected. But it's not. It isolates you from real people. Screens have even been described as being poisonous for teenagers.

    Psychologist Jean Twenge, a professor at San Diego State University, believes today's teenagers are “on the edge” of a major mental health crisis and requestes, “do anything that doesn't involve a screen”. The problem is, she claims, children born between 1995 and 2012 have grown up with a smart phone in their hands, and it has “changed every aspect” of their lives. The number of teenagers who actually see their friends frequently has dropped by more than 40% since 2000. In 2015, only 56% of 17-year-old went on a date, down from 85%. Modern teenagers are slower to learn to drive, or earn money and spend more time at home. They're “on their phone, in their room, alone and often depressed”, she says.

    Some critics, however, say we should encourage our children to spend more time online. Robert Hannigan, former director of GCHQ, said in August that Britain is badly short of engineers and computer scientists, and urged children to develop cyber skill to compete in the digital economy.

    I' m not the first to say that social media is inferior to real human contact, and harms mental health. Studies show teens who spend three hours a day online are 35% more likely to suicide(自杀).

    The suicide rate among girls aged 12 to 14 has more than doubled in a decade.

    Mr. Peter Johnson, aged twenty- three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route—through the boot (行李箱).

    Mr. Johnson's car had finished up in a ditch (沟渠) at Romney Marsin, Kent, after skidding on ice and hitting a bank. "Fortunately, the water began to come in only slowly," Mr. Johnson said. "I couldn't force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in."

    Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape.

    Later he said, "It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came."

    It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench (扳手) and began to work on the boot lock. Fifteen minutes passed by. "It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled clear as the car filled up."

    His hands and arms cut and bruised，Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer's wife, Mrs. Lucy Bates. Trembling in a blanket, he said, "That thirty minutes seemed like hours." Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.
