更多“Dr. Alexander Fleming was experimenting with a culture of deadly bacteria when he discover”相关的问题
第1题
听力原文： Alexander Fleming was bom on August 6th, 1881 on Darvel, Scotland. He was one of the eight children in the family. As a boy he showed a strong interest in nature.
Just before his 14th birthday he went to London to live with an older brother, Dr. Thomas Fleming. At 16 he went to work as a clerk for a shipping company.
When Fleming was twenty, an uncle died and left him a small sum of money. Determined to use the money wisely, he asked his brother's advice. Dr. Flemning suggested that he take an examination for medical college. He took the exam, and he got the highest score. He then began to study at St. Mary's Hospital in London.
When he completed his medical training, Fleming did not join his brother's practice as he had earlier intended. He decided to spend the rest of his life as a biologist.
It was in the fall of 1928 that Fleming discovered penicillin, the chemical produced by a mold called Penicillum. But it was two years before anyone attempted to produce pure penicillin in quantity. This was achieved by two other scientists, Howard Florey and Ernst Chain, during World War Ⅱ , in time to save the lives of thousands of wounded soldiers.
In 1945, he, Florey and Chain received the Nobel Prize for medicine.
Alexander Fleming died at the age of 71, on March 11th, 1955.

Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.
The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.
Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.
Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3.2 billion.
"We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation's health care costs," Dr. Duane Alexander, who heads the NIH 's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.
The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.
Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.
The people taking part will be from rural, urban and suburban areas, from all in- come and educational levels and from all racial groups, the NIH said.
The aim of the study is to find new ways to______.
A．conduct research
B．track public health
C．prevent or treat illness
D．speed up development
