五、阅读理解
Fleming saw many soldiers (士兵) die from infections (感染) in their wounds as he worked in a hospital during World War Ⅰ. This made Fleming decide to find a way to help the body fight infections.
In September 1928, Fleming left some glass dishes on a bench in his lab for two weeks. When he came back, he noticed something amazing.
Bacteria (细菌) were growing on all the glass dishes except one. On this dish mould (霉菌) had started to grow — the kind found on old bread.
The mould seemed to be giving off something that stopped the bacteria from growing. Fleming called it “mould juice”. He tried it on other bacteria, and it killed them too. Fleming became wild with joy and named it penicillin (青霉素).
Fleming did a few more experiments (实验) with penicillin, and he also wrote about it so other scientists could learn about it. However, no one seemed interested in his discovery. Fleming's boss thought he was wasting his time and it was impossible to kill bacteria. So he forgot about penicillin and started to work on other things.
In 1939, Ernest Chain, a scientist, and his boss, Howard Florey, were looking for medicines that could kill bacteria. They discovered Fleming's notes and decided to test penicillin. In 1940, they gave penicillin to some sick mice, who survived later. But those who didn't get it died. Florey shouted excitedly, “It looks like a wonder!” By 1943, the final tests on humans were finished successfully and the world had its first antibiotic (抗生素) medicine.
( ) 1. Why did bacteria stop growing on one of the dishes?
A. Because the “mould juice” killed them. B. Because some old bread was on the dish.
C. Because there was something special in the lab.
D. Because the dish was on the bench for two weeks.
( ) 2. Fleming had to give up his study on penicillin because ________.
A. something else was worth doing B. doing experiments cost much money
C. it couldn't kill bacteria D. his boss didn't believe his new discovery
( ) 3. What is Paragraph 4 mainly about?
A. The discovery of penicillin. B. The great work of Chain and Florey.
C. The tests on sick mice and humans. D. Fleming's notes about penicillin.
( ) 4. Which might be the best title for the text?
A. The Life of Fleming. B. The Story of Ernest Chain.
C. The Science of Fighting Against Infections.
D. The Birth of the World's First Antibiotic Medicine.
