单选题Passage2 Questions 6 to 10 are based on the following passage. Salt is as necessary to life as water. In many areas of Africa people once drank the urine（尿）of animals because they had no other source of salt. Without salt, human beings die. The human body demands that the amount of salt in the blood always stay the same. When the body does not get enough salt, it protects itself by letting less salt leave the body in. urine and sweat. But it cannot reduce this output to zero. Some salt is always escaping. On a completely saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys（肾） and sweat glands(腺). It then tries to adjust to this loss by speeding up its secretion(分泌) of water. (78) In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and, finally, death. The person dies of thirst. In cases where there is little or no water to drink, the body tries to do the opposite thing.Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of. salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant.6 Some African people once drank animal urine______.A when they were going to dieB because they were thirstyC because there was little saltD because they were short of water

共用题干第三篇Animal Testing ControversyTo paraphrase 18th-century statesman Edmund Burke,"All that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research.Scientists need to respond forcefully to animal rights advocates,whose arguments are confusing the public and thereby threatening advances in health knowledge and care.Leaders of the animal rights movement target biomedical research because it depends on public funding,and few people understand the process of health care research.Hearing allegations of cruelty to animals in research settings,many are perplexed that anyone would deliberately harm an animal.For example,a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is animals一no meat,no fur,no medicines.Asked if she opposed immunizations,she wanted to know if vaccines come from animal research.When assured that they do,she replied,"Then I would have to say yes."Asked what will happen when epidemics return,she said,"Don't worry,scientists will find some way of using computers."Such well-meaning people just don't understand.Scientists must communicate their message to the public in a compassionate,understandable way一in human terms,not in the language of molecular biology.We need to make clear the connection between animal research and a grandmother's hip replacement,a father's bypass operation,a baby's vaccinations,and even a pet's shots.To those who are unaware that animal research was nee-- ded to produce these treatments,as well as new treatments and vaccines,animal research seems wasteful at best and cruel at worst.Much can be done.Scientists could"adopt"middle school classes and present their own re-search.They should be quick to respond to letters to the editor,lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth.Research institutions could be opened to tours,to show that laboratory animals receive humane care.Finally,because the ultimate stakeholders are patients,the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper,who has made courageous statements about the value of animal research,but all who receive medical treatment.If good people do nothing there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.The author begins his article with Edmund Burke's words to________. A:call on scientists to take some actionsB:criticize the misguided cause of animal rightsC:warn of the doom of biomedical researchD:show the triumph of the animal rights movement
