1、BFT阅读(综合)模拟试卷 38及答案与解析 一、 Part 3 0 What will it mean to know the complete human genome. Eric Lander of MITs Whitehead Institute compares it to the discovery of the periodic table of the elements in the late 1800s. “Genomics is now providing biologys periodic table. “ says Lander. “Scientists will kn
2、ow that every phenomenon must be explainable in terms of this measly list“ which will fit on a single CD-ROM. Already researchers are extracting DNA from patients, attaching fluorescent molecules and sprinkling the sample on a glass chip whose surface is speckled with 10,000 known genes. A laser rea
3、ds the fluorescence, which indicates which of the known genes on the chip are in the mystery sample from the patient. In only the last few months such “gene expression monitoring“ has diagnosed a muscle tumor in a boy thought to have leukemia, and distinguished between two kinds of cancer that requi
4、re very different chemotherapy. But decoding the book of life poses daunting moral dilemmas. With knowledge of our genetic code will come the power to reengineer the human species. Biologists will be able to use the genome as a parts list much as customers scour a list of china to replace broken pla
5、tes and may well let prospective parents choose their unborn childs traits. Scientists have solid leads on genes for different temperaments, body builds, statures and cognitive abilities. And if anyone still believes that parents will recoil at praying God, and leave their babys fate in the hands of
6、 nature recall that couples have already created a frenzied market in eggs from Ivy League women. Beyond the profound ethical issues are practical concerns. The easier it is to change ourselves and our children, the less society may tolerate those who do not; warns Lori Andrews of Kent College of La
7、w. If genetic tests in uterus predict mental dullness, obesity, short stature or other undesirable traits of the moment will society disparage children whose parents let them be born with those traits? Already, Andrews finds, some nurses and doctors blame parents for bringing into the world a child
8、whose birth defect was diagnosable before delivery; how long will it be before the same condemnation applies to cosmetic imperfections? An even greater concern is that well-intentioned choices by millions of individual parents-to-be could add up to unforeseen consequences for all of humankind. It ju
9、st so happens that some disease genes also confer resistance to disease: carrying a gene for sickle cell anemia, for instance, brings resistance to malaria. Are we smart enough, and wise enough, to know how knocking out “bad“ genes will affect our evolution as a species? 1 The main similarity betwee
10、n the biologys periodic table and the periodic table of the elements is _. ( A) they are both lists ( B) they can be used to explain every phenomenon in their own fields ( C) they can be used to diagnose diseases ( D) they are both used to cure diseases 2 In the second paragraph, “the book of life“
11、refers to _. ( A) a book written by a prophet ( B) a book written by a biologist ( C) the periodic table of the elements ( D) the human genome 3 We can infer that some couples are eager to get eggs from Ivy league women because _. ( A) they cant give birth to children ( B) they want to have a good-l
12、ooking child ( C) they want to have a clever child ( D) curiosity drives them to do that 4 What is mainly discussed in the passage? ( A) The biologys periodic table. ( B) The possible influence of decoding human genome on humans life. ( C) Moral dilemmas posed by decoding human genome. ( D) Gene exp
13、ression monitoring. 5 What result might it lead to for all of humankind when parents could choose their unborn childs traits in the future? ( A) Desirable. ( B) Perfect. ( C) Unpredictable. ( D) Immoral. 6 It can be learned from the passage that _. ( A) gene expression monitoring is helpful in curin
14、g diseases ( B) all of the disease genes are harmful to human beings ( C) short people may be more looked down upon in future ( D) scientists are encouraged to do research on human genome 7 The authors attitude towards knowing the complete human genome can be described as _. ( A) critical ( B) objec
15、tive ( C) positive ( D) indifferent 7 The Planning Commission asserts that the needed reduction in acute care hospital beds can best be accomplished by closing the smaller hospitals, mainly voluntary and proprietary. This strategy follows from the argument that closing entire institutions saves more
16、 money than closing the equivalent number of beds scattered throughout the health system. The issue is not that simple. Larger hospitals generally are designed to provide more complex care. Routine care at large hospitals costs more than the same care given at smaller hospitals. Therefore, closure o
17、f all the small hospitals would commit the city to paying considerably more for in-patient care delivered at acute care hospitals than would be the case with a mixture of large and small institutions. Since reimbursement rates at the large hospitals are now based on total costs, paying the large ins
18、titutions a lower rate for routine care would simply raise the rates for complex care by a comparable amount. Such a reimbursement rate adjustment might make the charges for each individual case more accurately reflect the actual costs, but there would be no reduction in total costs. There is some e
19、vidence that giant hospitals are not the most efficient. Service organizations and medical care remains largely a service industry frequently find that savings of scale have an upper limit. Similarly, the quality of routine care in the very largest hospitals appears to be less than optimum. Also, th
20、e concentration of all hospital beds in a few locations may affect the access to care. Thus, simply closing the smaller hospitals will not necessarily save money or improve the quality of care. Since the fact remains that there are too many acute care hospital beds in the city, the problem is to dev
21、ise a proper strategy for selecting and urging the closure of the excess beds. However many it may turn out to be. The closing of whole buildings within large medical centers has many of the cost advantages of closing the whole of smaller institutions, because the fixed costs can also be reduced in
22、such cases. Unfortunately, many of the separate buildings at medical centers are special-use facilities. The relocation of which is extremely costly. Still a search should be made for such opportunities. The current lack of adequate ambulatory care facilities raises another possibility. Some floors
23、or other large compact areas of hospital could be transferred from in-patient to ambulatory uses. Reimbursement of ambulatory services is chaotic, but the problem is being addressed. The overhead associated with the entire hospital should not be charged even pro rate to the ambulatory facilities. Ev
24、en if it were, the total cost would probably be less than that of building a new facility. Many other issues would also need study, especially the potential overcentralization of ambulatory services. The Planning Commission language seems to imply that one reason for closing smaller hospitals is tha
