职称英语卫生类A级真题及答案 1
Screen Test
1. Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough, the disease can often be treated successfully. According to a, survey published last year, 21 countries have screening programmes. Nine of them, including Australia, Canada, the US and Spain, screen women under 50.
2. But the medical benefits of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser.
3. Researchers at the Polytechnic University1 of Valencia analysed the effect of screening more than 160, 000 women at 11 local clinics. After estimating the women’s cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause.
4. The mathematical model recommended by Britain’s National Radiological Protection Board (NRPB)predicted that the screening programme would cause 36 cancers per 100,000 women, 18 of them fatal. The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers.
5. The researchers argue that the level of radiation-induced cancers is “not very significant” compared to the far larger number of cancers that are discovered and treated. The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 women screened.
6. But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45, because they would be exposed to less radiation. The results of their study, they suggest, could help “optimise the technique” for breast cancer screening.
7. “There is a trade-off between the diagnostic benefits of breast screening and its risks,” admits Michael Clark of the NRPB. But he warns that the study should be interpreted with caution. “On the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life. That’s why radiation exposure should be minimised in any screening programme.”

答案与题解：
1.A A说的是：用X射线检查可能对年轻女人不好。下面是第二段讲的意思：但是。用X射线检查年轻女人，就医学上的好处而论，是有争议的，部分原因是辐射有诱发癌症的小小的危险。另外，年轻女人乳房组织紧密。给予的X射线的剂量要多一些。
2.B B说的是：调查用X射线检查的结果。第三段的第一句话是这么说的：Valencia理工大学的研究人员分析了11个社区诊所用X射线检查16万以上女人的结果。
3.C C说的是：两种不同的模型预测的结果。第四段讲的是，两种不同的数学模型在预测用X射线检査女人诱发癌症的结果是不一样的。C概括了这段话。
4.D D说的是：辐射诱发癌症的危险是很小的。第五段的第一句话是这么说的：The researchers argue that the level of radiation-induced cancers is “not very significant” compared to the far larger number of cancers that are discovered and treated.研究人员争辩说，与发现后接受治疗的癌症数字相比，由辐射诱发癌症的数字是很小的。
5.C C与题干生成：Early discovery of breast cancer may save a life.乳腺癌发现得早也许能挽救生命。答案可以从第一段中找到。
6.D D 与题干生成：Advantages of screening women under 50 are still open to debate.对50岁以下的女人用X射线检查的好处仍然是有争议的`。第二段的第一个句子是这么说的：But the medical benefits of screening these younger women are controversial... 但是，用X射线检查年轻女人，就医学上的好处而论，是有争议的……这两个句子用词有些差别，基本意思是相同的。
7.E E与题干生成：Delaying the age at which screening starts may reduce the risk of– radiation triggering a cancer.延缓用X射线检查的年龄也许能减少辐射诱发癌症的危险。答案在第六段。
8.F F与题干生成：Radiation exposure should be reduced to the minimum.应把接受福射降低到最小的程度。答案在文章的最后一句。
职称英语卫生类A级真题及答案 2
Young Female Chimps Outlearn Their Brothers
Young female chimps are faster and better learners than young male chimps, suggests a new study, echoing learning differences seen in human girls and boys.
While young male chimps pass their time playing. Young female chimps carefully study their mothers. As a result, they learn how to fish for tasty termite snacks over two years before the boys.
Elizabeth Lonsdorf, now at Lincoln Park Zoo in Chicago, US, and colleagues at the University of Minnesota, Saint Paul spent four years watching how young chimpanzees in the Gombe National Park in Tanzania learned “cultural behavior”.
The sex differences in learning behavior were “consistent and strikingly apparent”, says the team. The researchers point out that similar differences are seen in human children with regard to skills such as writing. “A sex-based learning differences may therefore date back at least to the last common ancestor of chimpanzees and humans.” they write in the journal Nature.
Chimps make flexible tools from vegetation and then them into termite mounds, extract them and then munch the termites clinging onto the tool. The researchers used video cameras to record this feeding behavior and found that each chimp mother had her own technique, such as how she used tools of different lengths.
Analysis of the six infants whose ages were known showed that girl chimps were an average of 31 months old when they succeeded in fishing out their termites, where the boy chimps were aged 58 months on average. Females were also more skillful at getting out more termites with every dip and used techniques similar to their mothers while males did not.
Instead of studying their mothers, the boy chimps spent a significantly greater amount of time frolicking around the termite mound. Behaviors such as playing or swinging might help the male infants later in life when typically male activities like hunting or fighting for dominance become important, suggest the researchers.
Lonsdorf adds that there just two main sources of animal protein for chimps — the termites or colobus monkeys. “Mature males often hunt monkeys up trees, but females are almost always either pregnant or burdened with a clinging infant. This makes hunting difficult,” she says .“Adult females spend more time fishing for termites than males.” So becoming proficient at termite fishing could mean adult females eat better, “They can watch their offspring at the same time. The young of both sexes seen to pursue activities related to their adult sex roles{10} at a very young age.”
练习:
1. Why do young female chimps learn faster than young male chimps at fishing for termites? A Because young female chimps don’t play with their brothers. B Because young female chimps begin to study their mothers earlier. C Because young male chimps never learn to fish for termites. D Because young male chimps are not interested in termites.
2. What are the tools with which chimps fish for termites? A Tree branches. B Vegetation. C Fruits. D Grass.
3. Which of the Following is true about chimps fishing for termites according to paragraph 6? A Males often compete with females in fishing for termites. B Males could get out more termites with every dip. C Females could get out more termites with every dip. D Males are good at mastering technique for fishing for termites.
4. How did the researchers explain the fact that boy chimps spent more time on playing? A They like hunting. B They enjoy fighting. C It helps them to stay fit. D It will make them good fighters and hunters in the future.
5. According to the last paragrnph, which of the following is NOT true? A Adult chimps hunt monkeys while young chimps fish for termites. B The main source of animal protein for male chimps is colobus monkeys. C The main source of animal protein for female chimps is termites. D Female chimps fish for termites while watching their children.
答案与题解 :
1. B 根据第二段的内容，雄性小猩猩将时间用来玩要，而雌性小猩猩则研究她们母亲的行为，因此，她们比雄性小猩猩早两年学会捕食白蚁。 A、D文中没有提到， C与问题没有关系。
2. B第五段的第一个句子告诉我们，猩猩用植物作成方便的工具，用来捕食白蚁。 A、C和 D均是错误的。
3. C 该段告诉我们，对六只小猩猩的分析表明，雌性小猩狠不但较早学会捕食白蚁 .而且能比雄性小猩猩更为熟练地捕食到更多的白蚁。所以， B和 D都不是正确选项。 A项内容文中没有提到。
4. D A、B和 C都是错误的，因为文中没有捉到雄性小猩猩喜欢猎食和打斗，也没有提及玩耍能使他们更健康。D是正确答案。第七段昀后一句说，他们喜欢玩耍的.行为有助于他们长大后的生活，因为，到那时，他们要猎食和争权夺位。
5. A 根据昀后一段的内容，成年雄猩猩主要猎食生活在树上的一种叫做 colobus（疣猴）的猴子，而雌性猩猩捕食白蚁。所以 A是正确选项。 B、C和 D的内容均可在该段中找到。
