14．　　"I spent my whole life doing one thing, " Gu Fangzhou once said. Known as "the father of sugar pills (糖丸)", Gu passed away at age 92 on January 2, 2019. Eight months later, he received a national honorary title (荣誉称号) "the People's Scientist" for his polio (脊髓灰质炎) research.
　　Gu Fangzhou, a famous medical scientist, was born in June, 1926. Gu's family faced a difficult time with the sudden death of his father. He studied hard and finally entered Peking University as a medical student in 1944. After graduation, Gu made the decision to work;to help, improve public health.
　　In 1955, polio broke out in Nantong, Jiangsu Province. It paralyzed (使瘫痪) 1, 680 people, mostly children aged below seven. It spread to neighboring areas, and resulted in 466 deaths. Gu was asked to lead polio research in 1957. "At that time the only way to prevent polio was to invent a vaccine (疫苗), "said Gu.
　　In 1959 Gu succeeded in developing the first polio live vaccine. Later, he developed the "sugar﹣ coated pill" vaccine in the early 1960s. It not only tasted better but was more affordable and easier to keep. In order to test the vaccine, Gu himself tried the vaccine. and later his one ﹣ month ﹣ old son was vaccinated. This inspired his team to vaccinate their kids. They became the first group of people in China to try a polio vaccine.
　　Gradually, the sugar﹣coated polio vaccine was made available in China. It saved millions of people, especially kids, from being disabled. In 2000, the WHO announced that China was already a polio ﹣ free country. "We feel satisfied. I can tell people that I tried my best, and your kids will no longer get polio, " said Gu. "That's all we hoped for. "

15．　　Formal dining (正式就餐) can be an enjoyable experience. However, an invitation to a formal meal can make many people nervous. Here are some ideas that can help you to be. a well ﹣ behaved guest.
　　Basic table manners should be kept in mind first. Keep your elbows off the table, and chew (咀嚼) with your mouth closed. Never pick your teeth at the table. While it's OK to use your fingers when eating bread or sandwiches, most foods should be eaten with' utensils (餐具) .
　　Thinking more of others is necessary to a pleasant dining experience. Be polite, eat slowly and take time to converse with those around you. Laughter is perfectly fine, but never shout across the table to make yourself heard. Moreover, keep your phone on silent, and check it as little as possible during the meal.
　　If you don't know what to do at the table, just begin with your napkin. When you sit down, open the napkin at once and place it over your knees. Whenever you need to excuse yourself, leave it in your seat.
　　When you sit down, you'll find forks on your left as well as knives and spoons on your right. These utensils will be in different shapes and sizes, but don't be worried ! Just begin with the outer utensils and work towards the middle. Still, if you're uncertain what to do, simply follow your host's lead, and you can't go wrong.
]　　When the meal is over, tidy up your napkin and put it down to the left of you. Before you leave, be sure to express your thankfulness to your host.

16．　　When people think of life in Europe hundreds of years ago, they often think of castles (城堡) built of stone, with huge towers. (1)       . Hundreds of their relatives, soldiers and workers also lived there.
　　(2)       It was busy all day and every day. Usually there was a good distance (距离) between a castle's kitchen and other rooms and buildings, especially. the great hall, a large room where people came together for meals and other activities. (3)       The kitchen workers needed to use fire for cooking, but sometimes kitchen fires accidentally grew out of control and could spread to other parts of the castle. That's why the kitchen was usually far away.
　　Each kitchen also had a garden to grow vegetables. (4)       People stored some vegetables underground, but not for long, so most vegetables were picked fresh from the castle garden as they were needed.
　　Of course, a king's dinner included many other dishes like bread, meat, and fish. (5)       So the castle kitchen had a whole team of people to make different dishes. The chef (主厨) was like a head manager. He was responsible for making sure that the team of kitchen workers did their job right. Although chefs would also cook some dishes of the meal, their main task was to supervise (管理) the whole team.

17．　　Imagine that you are driving down a road late at night. You look to the side of the road and find that there is a car accident. There are people in the car, and they, are probably hurt. What would you do in that situation? Would you ignore (忽视) the people and keep driving? Or would you stop your car and try to help them?
　　In the past, most people didn't think of it as a problem. They would stop to help the injured without thinking twice. But people think differently now. Lots of people don't want to give help. One of the reason is that sometimes they might hurt the people they are trying to save, and the injured might sue (控告) them. Sometimes, the people who try to help have to pay lots of money just for doing good to others. Many people do not want to get sued for being nice. So they ignore others in need of help.
　　Because so many people are afraid of getting into trouble, a few countries have passed a special law. The law provides protection for people who try to help others. Thanks to the law, the injured can't sue anyone who gives a helping hand, In countries with this law, people are not afraid to help out anymore.
