Question

George Washington Carver showed that plant life was more than just food for animals and humans. Carver’s first step was to analyze 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(合成纖維織物). Each day people depend on and use synthetics made from raw materials. All his life Carver battled against the disposal of waste materials, and warned of the growing need to develop substitutes(代用品) 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(申請專利) his discoveries or get wealthy from them. He turned down many offers to leave Tuskegee Institute to become a 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 in the Mycology and Plant Disease Survey of the Department of Agriculture, he accepted the position with the understanding that he wouldn’t leave Tuskegee. An authority on plant disease—especially of the fungus(真菌) variety—Carver sent hundreds of specimens(標(biāo)本) to the United States Department of Agriculture. At the peak of his career, Carver’s fame and influence were known on every continent.

A. It mainly tells us about Gorge Washington Carver, a great chemurgist.

B. It mainly tells us about chemurgy.

C. It mainly tells us about the research made in Tuskegee.

D. It mainly tells us about the development of making synthetics.

The underlined word “disposal” in the second paragraph mean “________”.

C. management      D. keeping

Which of the following is NOT mentioned in the passage?

A. Make a study of plant parts.

B. Make new products out of farm products.

C. Carver helped the United States Department of Agriculture.

D. Make a study on animal disease.

Which of the following is NOT true according to the passage?

A. Carver never patented what he discovered.

B. Carver refused many offers to work in private companies.

C. Carver made little money out of his discoveries.

D. Carver helped Edison invent electric light.

Answer 1

【小題1】A

【小題2】B

【小題3】D

【小題4】D

解析:

【小題1】A  主旨大意題。從文章的第 1 句 George Washington Carver showed that plant life was more than just food for animals and humans 和文章的最后一句 At the peak of his career, Carver’s fame and influence were known on every continent 以及全文的內(nèi)容可看出，全文是在介紹 Carver 在植物方面的研究對世界所產(chǎn)生的影響。故答案選 A。

【小題2】B 詞義猜測題。根據(jù)上文的 battled against 以及下文的 of waste materials, and warned of the growing need to develop substitutes for the natural substances being used up by humans  可推知答案為 B，意思是“對廢物不恰當(dāng)?shù)奶幹谩薄?/p>

【小題3】D  事實細(xì)節(jié)題。根據(jù)文章第 1 段的第 2 句 排除選項 A；根據(jù)文章第 2 段的第 1 句 排除選項 B；根據(jù)文章最后一段的倒數(shù)第 2 句 排除選項 C；從而得出答案為 D。

【小題4】D  推理判斷題。根據(jù)文章最后一段的第 2 句 排除選項 A；根據(jù)文章最后一段的第 3 句排除選項 B；根據(jù)文章最后一段的第 2 句 排除選項C；從而得出答案為 D。
