for animals and humans. Carver's first step was to study plant parts to find out what they were made of. He then combined these simpler isolated substances with other substances to create new products. The branch of chemistry that studies and finds ways to use raw materials from farm products to make industrial products is called chemurgy. Carver was one of the first and greatest chemurgists of all time. Today, the science of chemurgy is better known as the science of synthetics(人造合成)。 Each day people depend on and use synthetic materials made from raw materials. All his life Carver battled against the disposal of waste materials and warned of the growing need to develop substitutes (fam) for the natural substances being used up by humans. Carver never cared about getting credit(#) for the new products he created. He never tried to patent(申请专利) his discoveries or get wealthy from them. He turned down many offers to leave Tuskegee Institute to become a rich scientist in private industry. Thomas Edison, inventor of the electric light, offered him a laboratory in Detroit to carry out food research. When the United States government made him a collaborator (A fEt) in the Mycology and Plant Disease Survey of the Department of Agriculture, he accepted the position with the understanding that he wouldn't have to leave Tuskegee. An authority on plant diseases-especially of the fungus variety-Carver sent hundreds of specimens to the United States Department of Agriculture. At the peak of his carreer Carver's fame and influence were known on every continent. 16. The passage is mainly concerned with A. the use of plants as a source of nutrition B. the research conducted at Tuskegee Institute C. the progress of the science of synthetics D. the work and career of George Washington Carver 17. In Line 2, the word"step"could best be replaced by A. footprint B action C. scale D stair 18. According to the passage chemurgy can be defined as the A development of industrial products from farm products B. research on chemistry of the soil C study of the relationship between sunlight and energy D combination of chemistry and metallurgy 19.
