C Louis Pasteur was born in Dole, France on December 27, 1822. His family was poor, and during his early education Pasteur was an ordinary student who enjoyed art and singing. However, when Pasteur was exposed to science as a teenager, he knew he had found his career. In 1838, Pasteur went to college to become a science teacher. He then became a chemistry professor at the University of Strasbourg. He got married in 1849 and had five children. However, three died young from typhoid fever . It was the deaths of his children that drove Pasteur to investigate the infectious disease in order to find a cure. During Pasteur’s time, people believed that bacteria appeared due to “spontaneous generation . They thought that the bacteria just appeared out of nowhere. Pasteur carried out experiments to see if this was true. Through his experiments he proved that germs were living things that came from other living things. They didn’t just spontaneously appear. This was a major discovery in the study of biology and earned Pasteur the title of Father of Germ Theory. As Pasteur learned more about bacteria, he began to think they may be the cause of diseases in humans. When the French silk market was threatened by a disease to silkworms (蝉), Pasteur decided to investigate. He discovered that this disease was caused by germs. By killing them from the silkworm farms, he was able to cease the disease and save the French silk business. Today Louis Pasteur is known as one of the most important scientists in history. His discoveries led to an understanding of bacteria and diseases that has helped save millions and millions of lives. 53. After his children’s deaths, Louis Pasteur . A. became afraid of infectious diseases B. was frustrated and wanted to do nothing C. decided to find out how to treat the disease D. didn’t know it was typhoid fever that caused their deaths 54. What is implied about Louis Pasteur’s discovery in Paragraph 3? A. It supported what most people thought at that time. B. It revealed that bacteria often appeared out of nowhere. C. It attracted the attention of the Father of Germ Theory. D. It was a very important discovery in the history of biology. 55. What does the underlined word “cease in Paragraph 4 probably mean? A. End. B. Find. C. Develop. D. Spread. 56. What is the text mainly about? A. A disease that killed children easily in history. B. A great scientist in the field of biology in history. C. Some of the most important scientists in history. D. Some of the most important discoveries in history. 查看更多

 

题目列表(包括答案和解析)

Between 10,000 and 15,000 years ago, some humans discontinued their wandering hunting and gathering and settled down to farm. Grain was the first domesticated crop that started that farming process.
The oldest proven records of brewing are about 6,000 years old and refer to the Sumerians. Sumeria lay between the Tigris and Euphrates rivers including Southern Mesopotamia. It is said that the Sumerians discovered the fermentation (发酵) process by chance. No one knows today exactly how this occurred, but it could be that a piece of bread or grain became wet and a short time later, it began to ferment.
The Sumerians were able to repeat this process and are assumed to be the first civilized culture to brew beer. They had discovered a “divine drink” which certainly was a gift from the gods. The word beer comes from the Latin word bibere, meaning “to drink”, and the Spanish word cerveza originates from the Greek goddess of agriculture, Ceres.
A vitamin-rich porridge, used daily, beer is reported to have increased health and longevity and reduced disease and malnutrition (营养不良). The self-medicating properties of alcohol-rich beer also eased the tensions and stresses of daily living in a hostile world. The use of yeast (酵母) was not yet known at that time. The success of the fermentation process was left to chance, as the brewers unknowingly relied on yeast particles in the air.
Considerable scientific research took place in breweries (酿酒厂) in the 19th century. A famous work from 1876 by Louis Pasteur was Studies Concerning Beer where he revealed his knowledge of micro-organisms. By establishing that yeast is a living microorganism, Pasteur opened the gates for accurately controlling the conversion (转换) of sugar to alcohol.
Another discovery in beer brewing was the work of Christian Hansen, a Danish scientist, who successfully isolated a single yeast cell and induced it to reproduce on an artificial culture medium. With the resulting yeast multiplication (繁殖) methods, the purity of the fermenting process has been improved.
【小题1】According to the passage, who was the first to brew beer?

A.The Greeks.B.Christian Hansen.
C.Louis Pasteur.D.The Sumerians.
【小题2】The last two paragraphs mainly talk about        .

Louis Pasteur

Louis Pasteur, one of the world's great scientists, was born in 1822, and died in 1895.While still a young boy, Louis Pasteur made his decision to become a scientist. He spent much of his life time studying the diseases of cattle, chickens and other tame animals. His wife learned to help him with his work. Almost everyone knows that Pasteur is the man responsible for finding a way of preventing milk from spoiling (变质). Not many people know he was the first to imagine and to prove that air we breathe is full of germs (细菌).  One of his greatest successes was finding a treatment for people and animals to prevent a disease called rabies (狂犬病). Louis Pasteur won many honors and could have got large amount of money. But Pasteur preferred to live simply. The real happiness of this unusual man came from his work. Louis Pasteur did so well in his life that the French government took up his work and created the Institute Pasteur in the year 1888.
