[单项选择]The Function of Adrenocorticotriopin
Some people can quite accurately time the end of their night’’s sleep at will, without using an alarm clock, demonstrating that it is possible to voluntarily control a state of consciousness that is characterized by a loss of volition and attentional guidance. Here we show that the expectation that sleep will come to an end at a certain time induces a marked increase in the concentration of the hormone adrenocorticotriopin(促肾上腺皮质激素) in the blood one hour before waking. The regulation of adrenocorticotropin release during nocturnal sleep is therefore not confined to daily rhythms._________(46).
_________(47). Normally, the release of adrenocorticotropin and cortisol(皮质醇) increases during late stages of sleeping, reaching a daily maximum at the time of spontaneous waking. Adrenocorticotropin and Cortisol are also released from the pituitary-adrenal system in a major adaptive response to stress, and are secreted in anticipation of stressful e

[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] The Asian Flu Virus
In 1957, a doctor in Singapore noticed that hospitals were treating an unusual number of influenza-like cases. Influenza is sometimes called "flu" or as "bad cold". He took specimens from the throats of patients in his hospital and was able to find the virus of this influenza.
There are three main types of the influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instruments at the hospital the doctor recognized that the outbreak was due to a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H. 0. published the important news alongside reports of a similar outbreak in Hong Kong, where about 15%-20% of the population had become ill.

[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
A. are central to the medical staff
B. play an important role in caring patients
C. can work effectively without physicians
D. are always in close contact with the patients

[单项选择] Competition
The question of whether war is inevitable is one which has concerned many of the worlds great writers. Before considering this question, it will be useful to introduce some related concepts. Conflict, defined as opposition among social entities directed against one another, is distinguished from competition, defined as opposition among social entities independently striving for something which is in inadequate supply. Competitors may not be aware of one another, while the parties to a conflict are. Conflict and competition are both categories of opposition, which has been defined as a process by which social entities function in the disservice of one another. Opposition is thus contrasted with cooperation, the process by which social entities function in the service of one another. These definitions are necessary because it is important to emphasize that competition between individuals or groups is inevitable in a world of limited reso

[单项选择] Old Mothers’ Children Have Higher Diabetes (糖尿病) Risk
Children of older mothers run a higher risk of developing insulin-dependent (胰岛素依赖型的) diabetes, the British Medical Journal said. "A strong association was found between increasing maternal (母亲的) age at delivery and risk of (insulin-dependent) diabetes in the child. Risk was highest in firstborn children and decreased progressively with higher birth order," Professor Edwin Gale and colleagues at Southmead Hospital in Bristol said. Diabetes is a serious, incurable, lifelong disease characterized (以......作为特性) by all inability to control the amount of sugar in the blood. Insulin-dependent diabetes, which mainly affects children, is treated by administering the hormone insulin. Gale looked into 1,375 families in the Oxford area where one or more children had diabetes and found that the risk of a child developing insulin-dependent diabetes increased by 25 percent for each five-year band of the mothers age.
