George Washington Carver showed that plant life was more than just food for animals and humans. Carver’s first step was to【S1】______plant parts to find out what they were made of. He then combined these【S2】______isolated substance with other substances to create new products.
The branch of chemistry that studies and finds ways to use raw【S3】______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. Each day people【S4】______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 for the【S5】______substances being used up by humans.
Carver never cared about getting credit for the new products he created. He【S6】______tried to patent(获取专利)his discoveries or get wealthy from them. He turned down offers to leave Tuskegee Institute to become a【S7】______scientist in a private industry. Thomas Edison, inventor of the electric light, once offered him a laboratory in Detroit to carry out food【S8】______. Later, he became【S9】______of the Mycology and Plant Disease Survey of the Department of Agriculture. At the peak of his career, Carver’s【S10】______and influence were known on every continent.
A)depend I)research
B)always J)materials
C)director K)complex
D)factory L)natural
E)simpler M)analyze
F)never N)wealthy
G)fame O)compounds
H)farmer
【S2】
选项
答案
E
解析
考查形容词的使用。根据句法分析,这里缺少定语,通常为形容同;再看意思,Carver将分解出来的物质与其他物质结合在一起来合成新产品。这些分解出来的物质相对于植物原先的部分来说,显然要“简单”“单一”一些,而不是更“复杂的”。综上所述,我们可以确定[E]simpler为该题答案。
