When he died in April of 1993, Dr. Jeol Hiderbrand was 101 years old, had been married for seventy years, and had taught freshmen chemistry to over 40,000 students. In addition, he had published a popular textbook and dozens of articles, had managed the U. S. Olympic ski team, and had discovered a way to allow deep-sea divers to stay underwater longer. In his own way, Dr. Jeol Hiderbrand was certainly a genius.
Dr. Jeol Hiderbrand’s interest in chemistry began at an early age. In an interview, he once said that his interest formed because he was fortunate enough to be born before there was a television, so he had to make his own decisions about what to pay attention to. Even as a student in high school, Dr. Jeol Hiderbrand had the reputation as the one who learned more chemistry than his teacher knew. As a result he was given the keys to the high school chemistry lab, and there he discovered that the correct formula for a certain chemical compound was not the one given in his chemistry book but a totally different one. Dr. Jeol Hiderbrand went on to teach at theUniversity of California at Berkeley and remained there for almost forty years.
During that time, Dr. Jeol Hiderbrand discovered that the gas helium could be combined with oxygen for use as diving gas to allow divers to dive deeper and take the great pressure of the water without the physical discomforts that had been experienced when they used another gas, nitrogen. The use of helium for deep-sea diving is now standard practice.
Dr. Jeol Hiderbrand was also valuable to his country during both World Wars. In World War I he analyzed the poisonous gases used on the battlefield and helped develop a truck that could clean and treat soldiers’ clothes which had been contaminated by poisonous gases during fighting. In World War II, he helped develop a type of the snowmobile, a vehicle used to carry soldiers through the snow in northern countries.
Dr. Jeol Hiderbrand’s retirement from teaching at the age of seventy was required by state law in California. He objected to this, joking that he thought a teacher’s time of retirement ought to be determined not by age but by how many of that teacher’s students were still awake after the first fifteen minutes of class! Dr. Jeol Hiderbrand’s career continued, however, and was still going strong at the age of 100, when he published an article on the theory of chemical solutions. Dr. Jeol Hiderbrand’s love of life and his interest in it were an inspiration to all who knew him. When asked once how he could have such ageless energy and vigor, he said, " I chose my ancestors(祖先)carefully. "
The use of helium for deep-sea diving______.
选项
A、helped to overcome the physical discomforts the divers experienced when nitrogen was used
B、was found by Dr. Jeol Hiderbrand
C、is still universally acknowledged as standard practice up to now
D、All that is included in A, B, and C
答案
D
解析
细节题。句子主语是“深海潜水中氦气的使用”,所提供的几个选项谓语A:“有助于克服潜水埙使用氮气潜水时身体的不适。”此陈述与原文第三段第一句话意义相符;B:“是由Jeol Hiderbrand博士发现的”,也是正确陈述。再看C,与原文第三段最后一句含义一致;因此可见三项陈述都对。因此,正确选项为D。
