Do you know that a cold could lead to serious infection or even death in the past? The Last Leaf , was written by O.Henry (1862-1910). At that time, people couldn’t treat pneumonia(肺炎). So the story The Last Leaf is based on this background. The Last Leaf Johnsy became very ill, with a 40-degree fever. At first, it looked like a flu, but it turned out to be pnuemonia. “Her only chance,” the doctor said, “is for her to want to live.” Johnsy was very plae, and she was looking out of the window and counting. “Six. There goes another one. There are only five left now. I want to see the last one fall. Then I will die.” Old Behrman was a painter, but he is a nobody. He was past 60 and earned a little money by being a model. Sue had to hand in a painting and asked Behrman to be her model. And she told him what Johnsy had said. The next morning, there was only one ivy leaf left. It is the last one and it will fall soon. At night, it got very cold and the rain froze as it hit the ground. However, the next morning, the leaf was still there. “Something has made that last leaf stay there. It is wrong to want to die, please bring me a little porridge now.” A few days later, the doctor said to Sue, “She is out of danger.” But Mr Behrman died. He was wet and icy cold from being out all night. Don’t you wonder why the leaf never moved? The Last Leaf He painted it on the wall the night when the last leaf fall. In 1928, something amazing happened A world-changing discovery appeared By accident! Cross-curricular connection / Medical science* Look and answer. Cross-curricular connection 05 An accident is not always a bad thing. Sometimes, it may contribute to a great discovery. Penicillin: an accidental discovery that changed the world Q: What’s this? Penicillium mould sample box. Q: Look at the title and pictures. What is the passage about? Pre-reading Title Penicillin: an accidental discovery that changed the world Predict & Discuss How was penicillin discovered? Why is it called a world-changing discovery? 1.7.2013 ‹#› Penicillin: an accidental discovery that changed the world Many people consider the discovery of penicillin to be a major turning point in the history of the world. Before penicillin, a simple cut or insect bite could lead to serious infection and even death. Similarly, diseases caused by bacteria were likely to kill patients within weeks or even days. Doctors tried their best, but their treatments often failed and many patients died. It is hard to believe that this world-changing discovery happened by accident! In 1928, a scientist in London called Alexander Fleming came back from holiday to find his laboratory in a bit of a mess. He noticed there was mould growing in some of the laboratory dishes left lying around. As he sorted through them, he noticed something extraordinary. There were no bacteria in areas around the mould. Fleming found that a substance in the mould was killing the bacteria. He called it “penicillin” and was excited about using it to fight infections in humans. Sadly, Fleming did not have the money or equipment to develop his research further. It was only in the 1940s that scientists in the United States were able to produce penicillin in large quantities. Other antibiotics were also developed during this period. Since then, antibiotics have been widely used to treat infections. However, in recent years, some people have become infected by bacteria that are able to survive antibiotic treatments. Because of these “superbugs”, it has become clear that we cannot rely completely on antibiotics in the future. Scientists are therefore working hard to find new ways to fight infections.

Why was the discovery of penicillin a major turning point? Before penicillin, a simple cut or insect bite could lead to serious infection and even death. Similarly, diseases caused by bacteria were likely to kill patients within weeks or even days. Doctors tried their best, but their treatments often failed and many patients died. Penicillin changed this situation and saved millions of lives, so it became a major turning point in medical history. 1.7.2013 ‹#› While-reading Discuss the questions in groups. 2.

We can learn that great scientific discoveries may happen by accident. We should also observe carefully and think deeply in our daily lives and studies. 1.7.2013 ‹#› Post-reading Using antibiotics wisely How should we use antibiotics wisely? We should not rely completely on antibiotics. We must use them properly and avoid overusing them in order to prevent the emergence of “superbugs”. 1.7.2013 ‹#› Homework 基础作业 1. 复述青霉素的发现与发展的历程，要求不少于 80 个词。 2. 口头回答以下问题： 1) Why was penicillin considered a “world-changing discovery”? 2) What are “superbugs”, and why are they a problem? 拓展作业 小组合作，完成介绍“介绍一位伟人”的展示项目。欣赏其他小组的作品，修改和丰富本小组的作品。有条件的班级可以把优秀作品真实发布在本班的公众号上。 26 Blues 143392.3 $
