单选题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 Hiderbrattd"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 the University 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 (氦气) 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 carefully.

单选题There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among "situations vacant", although it does not offer anyone a job, and sometimes it appears among "situations vacant", although it is not placed by someone looking for a job either. What it does is to offer help in applying for a job. "Contact us before writing your application," or "Make use of our long experience in preparing your curriculum vitae or job history," is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as art form in its own right. There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams," was about the average lever of advice offered to young people applying for their jobs when I left school. The letter was really just for openers, it was explained, and everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest. Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. "Your search is over. I am the person you are looking for," was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job in view. There is no doubt, however, that it is the increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.

单选题 Whenever I see anyone buying a National Lottery ticket I want to stop them and ask if they know just where their money is going. The lottery money is supposed to go to charity—but it makes me angry to see some of the socalled "good causes" it's being used to support. Also, Camelot, the organizers, have made a profit of ￡3 10.8 million in five months. We hear now that a lot of that money is boosting the pay packets of the company's bosses. For the past 10 years I've been helping to raise funds for a cancer research charity called Tenovus. My husband, Sandy, died from cancer 11 years ago—he was only 51. There's been a long line of deaths in our family through cancer and it's been devastating. I've also lost two sisters-in-law, my brother, Michael, my father-in-law and my father. That's apart from several close friends. The charity is 50 years old now and raises money mainly for breast cancer research. It also runs a support line for the families of cancer sufferers. Our local group raises money through dances, sales and coffee morning, and all the funds go directly to cancer research. In 1993 Tenovus raised 1￡3 million--and half that money came from sales of our own lottery tickets at supermarkets. But out income has dropped by half since the National Lottery was introduced. I'm not against people playing the National Lottery, but they should think about what they're doing. The chances of winning the jackpot are so small; they might as well throw their money away. The Government tells us that the proceeds are going to things like the arts and sports, but what about the National Health Service? They should give some cash to that, too. How can they justify spending ridiculous amounts of cash on so-called works of art—like displays of potatoes—or buying up Winston Churchill's papers at a cost of ￡12 million? So who really are the winners in the National Lottery? When I think of all that money people could be donating to cancer research, I could weep. It's time people realized bow charities across the country are suffering because of the National Lottery. It's disheartening and so infuriating.
