　　For a long time Chester Carlson carried around his little black box--the invention over which he had worked and struggled for years. He showed it to the directors of twenty-one large American corporations, such as “General Electric, International Business Machines（IBM）. Lockheed and RCA.”

　　Nobody wanted it.

　　Nobody wanted to invest a penny in it.

　　It must be painful for those directors to think of Chester Carlson now. For the little black box is the heart of the multi-billion-dollar Xerox Corporation. Carlson is the inventor of “xerography”（from two Greek words meaning “dry writing”）, the dry-printing process used in thousands and thousands of offices, businesses, industries, shops, and government agencies around the world.

　　Thanks to Carlson, it now takes minutes to copy a document which, twenty years ago, would have kept a secretary busy for a whole day. And for a few pennies anyone can have a copy of anything from cooking recipes to Greek poetry. More than thirty billion such copies are made each year.

　　When Chester Carlson went to work in a patent office in 1930, the copying methods were slow, dirty, and expensive. In his job, Carlson had to make many copies of patents for inventions. One night, after working late and painfully, he decided that somebody had better find an easier way to do it. He went to work in the kitchen of his apartment with measuring cups and cooking pots. By 1937, having developed a simple form of xerography, he applied for（申请）his first patent on the Process.

　　Then began Carlson's famous unsuccessful search for investors. Only in 1944 did the Battelle Memorial Institute of Columbus, Ohio, agree to spend $ 3,000 for research on Carlson's invention. According to the agreement, Carlson was to receive25 percent of all profits; his share would rise to 40 percent if he could repay Battelle the $ 3,000 within five years. This part of the agreement later brought millions of dollars to Carlson who, by borrowing from his family, had managed to repay his debt in time.

　　Even with Battelle's help, it took another year to find a company willing to buy Carlson's process. In 1945, Dr. John H. Dessauer, director of research of the Haloid Company（maker of copying machines）, decided to adopt and market the process, which was then named “Xerox.” Three years later, the Haloid Company had changed its own name to become the Xerox Corporation. It is now the thirty-ninth largest corporation in the United States, with sales of over four billion dollars a year.

Answer 1

答案：B;A;C;A
解析：

这篇记叙文讲述了Carlson的专利产品复印机的推销及投资研究情况. (1) 这是一道综合分析判断题.综观全文，尤其是根据短文第五自然段中 Thanks to Carlson，it now takes minutes to copy a document which，twenty years ago, would have kept a secretary for a whole day.就可以判断出，B是最佳选项. (2) 这是一道考查是否准确掌握文中所提供信息的题目.那时候，复印机还没有面世，他不可能操作复印机，所以B项有误；文中未提及C、D项的内容.根据短文倒数第三段中In his job，Carlson had to make many copies of Patents for inventions.可以看出，Carlson在专利办公室的工作是复制发明专利，故答案选A. (3) 这是一道正误辨认题.从短文倒数第三段中the copying methods were slow, dirty and expensive及after working late and painfully, he decided that somebody had better find an easy way to do it.可以判断出,A和B项都是有道理的，D项在原文出现过.只有C项在原文中无任何根据，为最佳选择. (4) 这是一道推理判断题. 根据短文倒数第二段中Only in 1944 did the Battelle Memorial Institute of Columbus，Ohio，agree to spend $3, 000 for research on Charlson's invention. 可以判断出，Carlson并未卖掉他的专利，只是获得了3000美元的投资，用以继续研究.B，C项的意思与此矛盾，短文未涉及D项内容，故最佳答案选A.
