[单项选择] The Gene Industry
Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls "metal—hungry microbes that might be used to mine valuable trace metals from ocean water". They have already demanded and won the right to patent new lifeforms.
Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of "microbe spills" that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination
A. using metal-hungry microbes .
B. making use of enzymes.
C. adjusting the engine.
D. patenting new life forms.

[单项选择]Ice Cream For Dogs
1. Humans not only love eating ice cream, they enjoy feeding it to their pets(宠物). Market studies show that two-thirds of all dog owners give ice cream to their dogs. Unfortunately, says William Tyznik, an expert on animal nutrition(营养)at Ohio State University, ice cream is not good for dogs. "It has milk sugar in it," he says," which dogs cannot digest very well. "
2. Bothered by that knowledge but aware of the desire of dog owners to please their companions, Tyznik invented a new frozen treat for dogs that, he says, is more nutritious than ice cream—and as much fun to eat. The product, called Frosty Paws, is made of a liquid by-product (副产品) of cheese and milk with the sugar removed. Frosty Paws also contains refined soy flour, water, vegetable oil, vitamins and minerals. It took Tyznik, who has also invented a horse feed (called Tizwhiz)and another dog food (named Tizbits), three years to perfect the Frosty Paws formulas, and two attempts to commercialize it

[单项选择] Flu Shots Or Not
It sounded like a good idea when New York City’’s mayor, Rudollph Giuliani, advised New Yorkers recently to get a flu shot. After all, 20,000 Americans each year die of influenza. And this year in particular, the mayor suggested, getting a flu shot might be an especially good idea, since it could help doctors distinguish between flu and the deadly inhalational (吸入的) form of anthrax (炭疽). How Both anthrax and flu exhibit strikingly similar symptoms—fever, chills and muscle aches—in the early days of the infection. Physicians would be quick to suspect anthrax in anyone who was vaccinated (接种疫苗) against flu and still developed fever and chills. That would give them a better chance to identify any new victims of terror while their infection was still in its earliest, most treatable stages.
Or so the mayor’’s reasoning went. Unfortunately, there are a couple of problems with his logic. For one thing, getting vaccinated against inf

[单项选择] Heart Attack
In the United States, and especially in big cities and rural areas, tens of thousands of people with hearts that should be good 【51】 to keep them alive die each year for lack of adequate first aid. In New York City, for example, a new study has shown that only one person in 100 outside of hospitals 【52】 after the heart suddenly stops pumping. In contrast, in Seattle, the survival 【53】 after such heart attacks is one in five.
"The difference can be traced 【54】 the effectiveness of the chain of survival", Dr. Joseph P. Ornato said. " Each link in the 【55】 must be strong enough for many lives to be 【56】 ".
The chain begins with an immediate telephone 【57】 for emergency help and the start within four minutes of the process needed for restarting the 【58】 working, by a family member or bystander (旁观者).
It continues with the prompt arrival-------within eight 【59】 ten minutes of a rescuer equipped with a special instrument that

[单项选择] How to Be a Nurse
The physicians in a hospital form the core of the medical staff. But they could not provide effective medical care to their patients without the help of numerous other medical employees. From the view point of the patients, the nursing staff is particularly important. Nurses are usually in close contact with patients as long as they are in the hospital.
A nurse does not study for as many years as a doctor. However each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night.
Under the supervision of the head nurse, the nursing staff must provide nursing services on a 24-hour basis and attend to patients’ needs. This responsibility continues around the clock, and so nurses must work in shifts. A shift is a period of duty usually eight in length. The nurses on the ward rotate their shifts. Some ta

[单项选择] Regeneration of Limbs
Most people would agree that it would be wonderful if humans could regenerate limbs. Those who have lost their arms or legs would be complete again. The day is still far off when this might happen. But in the last 10 years, doctors have reported regeneration in smaller parts of the body, most often fingers.
Regeneration is not a newly-discovered process. For centuries, scientists have seen it work in some kinds of animals. Break off a lizards (蜥蜴的) tail, for example, and it will grow a new tail. Scientists now are looking for a way to turn on this exciting ability in more highly-developed animals, including humans. Their experiments show that nerves, cell chemistry and the natural electric currents in the body all seem to have a part in this process.
The body of every animal contains general purpose cells that change into whatever kind of cells the body needs. Animals such as the lizard or salamander (蝾螈) use these cells
A. humans can never regenerate limbs
B. human limbs may be regenerated on some animals first
C. humans might be able to regenerate limbs in the future
D. regeneration of human limbs will soon become a reality

[单项选择]A New Method to Kill AIDS Virus
_________(46). But researchers won’’t know for a year or more whether it will work, scientist David Ho told journalists here Wednesday for the Fourth Conference in Viruses and Infections.
"This is a study that’’s in progress," said Ho, head of the Aaron Diamond AIDS Research Center, New York.
The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the disease, within 90 days of their infections. They’’ve been treated for up to 18 months. Four others have dropped out because of side effects or problems complying with the exacting drug system.
The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients. And, in the latest development, scientists have now tested lymph nodes (淋巴结) and semen (精液) from a few patients and found no virus reproducing there._________(47).
Ho has calculated that the drugs should be able to wipe out remaining viruses—at
