    China has its first Nobel Prize in Science. And the winner, 84-year-old Chinese scientist Tu Youyou, also became the first Chinese woman to win the Nobel Prize. She won the 2015 Nobel Prize in Physiology or Medicine with William C. Campbell, an Irish-born researcher, and Satoshi Omura of Japan. The three winners will share the prize of 8 million Swedish crowns ($920,000).

    Half of the Prize was given to William C. Campbell and Satoshi Omura for their new treatment against illness caused by roundworm parasites (寄生虫). Tu Youyou won the other half of the Prize for developing a medicine, Artemisinin(青蒿素), which can help people fight malaria(疟疾). More than 240 million people in Africa have benefited from the treatment, according to the WHO (World Health Organization), and more than 1.5 million lives have been saved since 2000, thanks to the medicine.

    Tu Youyou started her research in 1969 when she was chosen as the director of a government project to find anti-malaria medicines. She and her workmates studied ancient Chinese medicine books and many different traditional treatments. They did nearly 200 experiments before they finally succeeded in getting the material Qinghaosu, later known as Artemisinin, in the 1970s. This medicine became the standard treatment for malaria in the WHO's list of important medicines.

    Premier Li Keqiang congratulated Tu for winning the Prize. He said, "Tu's winning the prize shows China's progress in scientific and technological field, and marks a great contribution of Traditional Chinese Medicine (TCM) to human health."

    Although it's a late honor for Tu and the world's recognition of Traditional Chinese Medicine, Tu's winning the first Nobel Prize in Physiology or Medicine makes Chinese scientists encouraged and confident to achieve more success in the future.

    Bill is only fifteen years old，but he's already very rich．Two years ago，Bill began a football website（网站）for young people. "I became interested in computers when I was 8 years old  because my father's job is with computers．As a little boy，I also loved football and so I decided to make a website，especially for people of my age．"

    Bill started the "Football OK!" website two years ago，and now more than 20,000 people visit it every day．

    Bill is a schoolboy and a businessman as well．He usually gets up at six o'clock and looks at his e-mails．Then he goes to school from nine to four．In the evenings，he always works for about four hours on his website．

    Bill's next plan is a new website." At the moment I am thinking about a new website on American football，maybe for next year．"

    And is Bill the same person that he was three years ago? "'No，I am very different now．I have met a lot of interesting people on the website and I have traveled all over the world．" Bill doesn't know about the future．"Maybe I will sell the websites. I really don't know．I'll just wait and see."

    Some people say that when he is 21，Bill will be a millionaire（百万富翁). He always says, “Anything is possible”!

    The mystery(悬疑) stories of Sir Arthur Conan Doyle are famous all over the world.

    The detective in his stories is called Sherlock Holmes. He solves mysteries in a most surprising way. Through it all, his assistant, Dr Watson, watches with admiration(钦佩). Watson then writes up the story of the mystery afterwards.

    This is a useful story writing skill. Because Watson is not very clever, the story remains a mystery until the end. The readers can sometimes pick up some clues before he does! Then, to make Watson understand the mystery, Holmes has to explain it all, step by step. So we, the readers, get to see it step by step too. Watson is almost as good a character in the story as Sherlock Holmes!

    The very first time they meet, Holmes greatly surprises Watson. When they are first introduced, Holmes says to Watson, "How do you do? I see you have been to Afghanistan.”

    Watson is too amazed by this to ask Holmes how he knows this. Watson has, indeed, been to Afghanistan. Later, he asks Holmes about it. Holmes explains that there is nothing magical about what he does. He gets to know it all by very, very careful observation (观察).

Observation One

    Watson was introduced to Holmes as a doctor. Yet Holmes thought that the way he stood and walked made him seem like a soldier. So, this meant he was probably an army doctor.

Observation Two

    Watson's face was quite dark skinned. But his wrists(手腕) were pale. So his dark face was probably sunburnt. This meant that he had been to a hot, sunny country. As he was a working doctor, this was not a holiday. He must have gone with the army.

Observation Three

    At the time, the British army had soldiers at bases in many parts of the world. So there were still a lot of places to choose from. However, Holmes saw that Watson looked very tired and he was always holding his left arm, as if it was painful. So, he had probably been with the army to a place where they were fighting. There was only one place where the British army was fighting at that time: Afghanistan.

    Have you ever thought about what our food will be in the future?

{#blank#}1{#/blank#}

    More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. {#blank#}2{#/blank#}Instead, people will eat more fruit and vegetables. In this way, people may be healthier.

    {#blank#}3{#/blank#}Only about 29%of the Earth's area is land and the rest is sea, so some think maybe we can get more food from the sea.

    Besides, though rice supports more than half the world's population, it needs a lot of water to grow. {#blank#}4{#/blank#}Therefore, it might be impossible to grow rice in the future. Some farmers are experimenting with new crops. {#blank#}5{#/blank#}The soybean (黄豆) makes a good substitute (替代品) for rice and meat.
