I have been very lucky to have won the Nobel Prize twice. It is, of course, very exciting to have such an important recognition of my work, but the real pleasure was in the work itself. Scientific research is like an exploration of a voyage of discovery. You are continually trying out new things that have not been done before. Many of them will lead nowhere and you have to try something different, but sometimes an experiment does work and tells you something new and that is really exciting. However small the new finding may be, it is great to think “ I am the only person who knows this” and then you will have the fun of thinking what this finding will lead to and deciding what will be the next experiment. One of the best things about scientific research is that you are always doing something different and it is never boring. There are good times when things go well and bad times when they don’t. Some people get discouraged at the difficult times but when I have a failure, my policy has always been not to worry but to start planning the next experiment, which is always fun.

It is very exciting to make a new discovery. Some people will do the strangest things for this excitement, such as going round the world in a balloon or walking to the North Pole. There are not many new places to explore but there is a lot of new information to be discovered in science and a journey into this unknown area can be much more worthwhile and just as exciting.

I am sometimes asked, “What do you have to do to win a Nobel Prize?” My answer is: “I don’t know. I have never tried.” But I know of one way not to win one. There are some people whose main reason for doing science is to win prizes and they are always thinking about how to do it. Such people don’t succeed. To do good science you must be interested in it and enjoy doing experiments and thinking out problems. And, of course, you must be prepared to work hard and not to be too discouraged by failure.

B.You can make as much money as possible by doing the scientific research.

C.You may continue doing with something different and exciting, so you can never be tired of doing the scientific research.

B.He used to be worried about it for several days and never forget it.

C.He always gave up his study as the result of the failure.

材料一:埃及面积100.145万平方千米。人口达7950万。埃及受自然条件制约,资源和物产比较单一,工农业生产有待发展。可耕地只占全国总面积的3%,农产品产值占GDP的18%;工业基础薄弱,行业发展也不平衡,2001年工业生产占其国内生产总值的18.4%。埃及政府非常重视发展旅游业。旅游业已成为埃及第一大创汇来源, 大大高于其他几个外汇收入来源——石油出口收入、苏伊士运河通行费收入和海外劳工汇款。旅游业已成为埃及最重要的支柱产业。旅游业从业人员与农业、工矿业从业人员三分天下,各占30%左右。
