Now the smelly chemicals from the sweat of these lucky people have been identified by researchers, who are testing its effectiveness as a natural mosquito repellent (驱蚊剂 ). Everybody produces a mixture of chemicals with smells in their sweat, some of which attract biting insects. But people who do not get bitten also produce smelly chemicals that appear to mask the smells of the attractive chemicals. This masking is very effective in avoiding a mosquito’s bite, explains James Logan, a scientist who carried out the research with his colleagues. These helpful chemicals probably occur naturally in everybody’s sweat but some people have a much higher ratio (比例 ) than others. “It’s very exciting,” Logan says, “because these are totally natural chemicals with an effectiveness that pares favorably to other chemicals such as DEET, which is the best repellent available but has unwanted side effects.” A key chemical identified by Logan as a repellent is also “a natural food additive which has been proven safe”. He says, “And because it can be made by plants, it may one day be possible to massproduce it cheaply.” The repellent is currently being tested by 16 volunteers in Africa. Meanwhile, the researchers are testing the repellent against other biting insects. 49． Which can be concluded from this passage? A． Mosquitoes like to suck attractive people.

D Nursing at Beth Israel Hospital produces the best patient care possible. If we are to solve the nursing shortage, hospital administration and doctors everywhere would do well to follow Beth Israel’s example. At Beth Israel each patient is assigned to primary nurse who visits at length with the patient and constructs a fullscale health account that covers everything from his medical history to his motional state. Then he writes a care plan centered on the patient’s illness but which also includes everything else that is necessary. The primary nurse stays with the patient through his hospitalization, keeping track with his progress and seeking further advice from his doctor. If a patient at Beth Israel is not responding to treatment, it is not unmon for his nurse to propose another approach to the doctor. What the doctor at Beth Israel has in the primary nurse is a true colleague. Nursing at Beth Israel also involves a decentralized nursing administration。 every floor, every unit is a selfcontained anization. There are nurse managers instead of head nurses。 in addition to their medical duties they do all their own hiring and dismissing, employee advising, and they make salary remendations.
