A. have lessons every day B. have their examinations C. help their parents pick coffee beans D. help their parents decorate their houses 60. This passage is mainly about ______. A. Christopher Columbus B. Costa Rica C. some products from Costa Rica D. the education of Costa Rica B Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beriberi. He was going there to try and find a cure. At first, Eijkman thought some kind of germ (細(xì)菌 ) caused beriberi. He raised some chickens. He didn39。t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精煉米 ). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (維生素 ). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person39。s food. Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don39。t, they can also take vitamin pills. 61.

A. beriberi was caused by chickens B. the Javanese didn39。t like vitamins C. Christian Eijkman39。s experiment was successful D. the Javanese39。s disease was caused by a kind of germ C America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may bee lifelong feelings, extending (延伸 ) sometimes deeply into both families. Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy weling us and be pleased if we accept their hospitality (好客 ) easily. Another difficult point for us C
