问题 单项选择题

下列不属于二次文献的是()。

A.《中国药学文摘》(CPA.

B.《中国药学杂志》

C.《国际药学文摘》(IPA.

D.《医学文摘》(EM)

E.《医学索引》(IM)

答案

参考答案:B

解析:本题考查药学信息的分类。药学信息分为三类:①一级文献,即原始资料,包括国内外期刊、药学科技资料等药学资料,如《中国药学杂志》、《中国医院药学杂志》、《中国执业药师》、《中国新药》等杂志;②二级文献,即将原始资料加工后而成的目录、索引和文摘,如《中国药学文摘》(CPA)、《中文科技资料目录:医药卫生》、《中文科技资料目录:中草药》、《国际药学文摘》(IPA)、《化学文摘》(CA)、《生物学文摘》(BA)、《医学索引》(IM)、《医学文摘》(EM)等;③三级文献,即在一级、二级文献的基础上归纳、综合、整理后的出版物。包括药品集、药典、百科类、专著类及工具书。可以看出A、C、D、E选项均属于二级文献的范畴,而B选项属于一级文献范畴。

Philo Farnsworth was a man who made it possible for one of the most important communication devices — television to be created. Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah. He attended a very small school near his family’s farm. He did very well in school. He asked his teacher for special help in science. The teacher began helping Philo learn a great deal more than most young students could understand.

One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world’s best scientists were using special machines to try to make a kind of device to send pictures.

14-year-old Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic. Philo knew electrons could be made to move extremely fast. All he would have to do was to find a way to make electrons do the work.

Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it “light in a bottle”.

Several days later, Philo told his teacher about a device that could capture pictures. He drew a plan for it, which he gave his teacher. Philo’s drawing seemed very simple, but it clearly showed the information needed to build a television. In fact, all television equipment today still uses Philo’s early idea.

Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. In fact, experts say that probably only ten scientists in the world at that time could have understood his idea.

On September 7th, 1927, Philo turned on a device that was the first working television receiver. In another room was the first television camera. Philo had invented the special camera tube earlier that year.

The image produced on the receiver was not very clear, but the device worked. In1930, the United States government gave Philo patent documents. These would protect his invention from being copied by others.

56. Before he was 14 years old, _______________.

A. Philo had formed the idea of sending pictures and sound through the air

B. Philo had learned a great deal in science from his father

C. Philo had helped his parents on their family’s farm

A. a container sending pictures and sound through the air

B. a light box with a line of electrons in a bottle

C. a receiver that held light and sent it on a line of electrons

D. a way to make electrons send pictures

59. We can infer from the passage that _________________.

A. without his teacher’s help, he would never have become interested in science

B. he made the first working television receiver and the first television camera himself

C. Philo’s early ideas about the television could not be understood by most people of that time

D. his invention was recognized and protected immediately he made it
