Reading and Thinking： A Pioneer for All People 第一遍：词汇短语过关斩将A Pioneer for All PeopleYuan Longping, known as the “father of 1. h_______(杂交植物) rice”, is one of China’s most famous scientists. Yet, he considers himself a farmer because he continually works the land in his research.

His parents wanted him to pursue a career in science or medicine. However, what concerned him most was that farmers often had poor harvests and sometimes even had a serious 3. s__________(短缺) of food to eat. To 4. t________(解决) this 5. c________(危机), he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing. After graduating in 1953, he worked as a researcher. Yuan Longping realised that larger fields were not the solution. Instead, farmers needed to 6. b______(使增长) 7. y_______(产量) in the fields they had. How this, could be done was a challenging question at the time. Yuan was 8. c________(使相信) that the answer could be found in the creation of hybrid rice. A hybrid is a cross between two or more varieties of a species. One 9. c_______________(特征) of hybrids is that they usually 10. a________(获得) a higher yield than 11. c_______________(传统的) crops. However, whether it was possible to develop a hybrid of 12. self-p_________(授粉) plants such as rice was a matter of great debate. The common 13. a___________ (假定) then was that it could not be done.

Yuan’s innovation has helped feed not just China, but many other countries that depend on rice as well, such as India and Vietnam. Because of his invaluable contributions, Yuan Longping has received numerous awards both in China and abroad. Given that Yuan’s hybrids have made him quite wealthy, one might think he would retire to a life of 24. l________(闲暇). However, this is far from the case. 25. ______________(本质上), Yuan is still very much a farmer at heart. As a man of the 26. s______ (泥土), he cares little for 27. c________(名望) or money. Instead, he makes large donations to support agricultural research. What impresses people most about Yuan Longping is his ongoing ability to fulfill his dreams.

Indeed, his slim but strong body is just like that of millions of Chinese farmers, to whom he has devoted his life.(确实，他瘦削但结实的身躯看起来和他为之奉献了一生的千百万中国农民一样。) Yuan Longping was born in 1930 in Beijing. His parents wanted him to pursue a career in science or medicine. 2. However, what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage of food to eat.(然而，最让他担心的是，农民经常歉收，有时甚至严重缺乏食物。) To tackle this crisis, he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing.  After graduating in 1953, he worked as a researcher.

A hybrid is a cross between two or more varieties of a species. One characteristic of hybrids is that they usually attain a higher yield than conventional crops. However, whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate. The common assumption then was that it could not be done. 5. Through intense effort, Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974.(通过不懈的努力，袁隆平克服了巨大的技术难题，于1974年研制出了第一批可用于农业生产的杂交水稻。) This hybrid enabled farmers to expand their output greatly. Today, it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan’s hybrid strains, and his strains have allowed China’s farmers to produce around 200 million tons of rice per year. 6.Yuan’s innovation has helped feed not just China, but many other countries that depend on rice as well, such as India and Vietnam.(袁隆平的创新不仅帮助养活了中国，也养活了许多其他依赖大米的国家，如印度和越南。) Because of his invaluable contributions, Yuan Longping has received numerous awards both in China and abroad.   7.Given that Yuan’s hybrids have made him quite wealthy, one might think he would retire to a life of leisure.(考虑到杂交水稻使袁隆平变得相当富有，人们可能认为他会退休享受闲适的生活。) However, this is far from the case. 8.

Instead, he makes large donations to support agricultural research.(作为一个土生土长的人，他不太在乎名利。相反，他大量捐款支持农业科学研究。)   10.What impresses people most about Yuan Longping is his ongoing ability to fulfil his dreams.(袁隆平给人印象最深的是他不断实现梦想的能力。) Long ago, he envisioned rice plants as tall as sorghum, with each ear of rice as big as a broom, and each grain of rice as huge as a peanut. He succeeded in producing a kind of rice that could feed more people at home and abroad. His latest vision for “seawater rice” has also become a reality, and potentially opened up nearly one million square kilometres of salty land in China for rice production. 11.

O_______(有机的) FarmingC________(化学的) 3. p_________(杀虫剂) and artificial 4. f_________(肥料) have been in 5. w_________(普遍的) use in farming since the middle of the 20th century. When they were first introduced, many farmers welcomed them as a great way to fight crop disease and increase production. Over time, however, what some scientists have found is that their long-term use can sometimes harm both the land and people’s health. For example, pesticides can damage the land by killing not only harmful 6. b_______(细菌) and insects, but also helpful ones. In addition, these chemicals can stay in the soil and underground water sources for a long time. This affects the crops grown on the land and, 7. _________(转而), the animals and humans who 8. d______(消化) them. Many people worry that these chemicals may make them ill and even cause cancer. In fact, some pesticides like DDT have been prohibited in most countries because of the damage they cause to people and the environment. As for chemical fertilisers, crops grown with them usually grow too fast to be rich in 9. n________(营养). They may look beautiful on the outside, but inside there is usually more water than 10. e________(极其重要的) 11. m_________(矿物质), and they often have less flavour as well. As an 12. a___________(可供选择的事物), some farmers have switched to organic farming, and many customers have turned to organic food when they shop at the local 13. g________(食品杂货店). Organic farming is simply farming without using any chemicals. Organic farmers focus on keeping their soil rich and free of disease through natural means. For example, many organic farmers use natural waste from animals as fertiliser. This makes the soil in their fields richer in minerals. It also keeps the air, soil, water, and crops free of chemicals. Organic farmers also use many other methods to produce rich soil. They often change the kind of crop grown in each field every year. For 14. i________(实例), they may grow corn or wheat in a field one year, and then grow beans there the next. Why different crops are grown is because they put important minerals back into the ground, making it ready for the next batch of crops. Organic farmers also plant diverse crops that use different 15. d_______(深度) of soil to help keep it rich. For example peanuts grow on the ground’s surface, but many other vegetables put down deep 16. r_____(根茎). The goal of using different organic farming methods is to grow good food while avoiding damage to the environment or to people’s health. Some people would prefer to stop the use of man-made chemicals in agriculture 17. e________(完全地). What keeps them from doing so is the fact that chemical farming serves the high demand for food around the world. Organic farming is nowhere near able to meet that need. Therefore, there is still a long way to find a suitable solution that puts sufficient food on the dinner table while keeping people and the environment as healthy as possible.OrganicChemicalpesticidesfertiliserswidespread bacteriain turndigest  nutritionessentialminerals   alternativegrocery   instance  depthsroots    entirely    第二遍：基础语法披荆斩棘 Chemical Versus Organic FarmingChemical pesticides and artificial fertilisers 1.________ (be) in widespread use in farming since the middle of the 20th century.
