2019年6月英语六级阅读理解全真模拟题(13)
The case for college has been accepted without question for more than a generation. All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become “better” people, and learn to be more responsible citizens than those who don’t go.
But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don’t fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere with each other’s experiments and write false letters of recommendation in the intense competition for admission to graduate school. Other find no stimulation in their studies, and drop out—often encouraged by college administrators.
Some observers say the fault is with the young people themselves—they are spoiled and they are expecting too much. But that is a condemnation of the students as a whole, and doesn’t explain all campus unhappiness. Others blame the state of the world, and they are partly right. We have been told that young people have to go to college because our economy can’t absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb an army of trained twenty-two-year-olds, either.
Some adventuresome educators and watchers have openly begun to suggest that college may not be the best, the proper, the only place for every young person after the completion of high school. We may have been looking at all those surveys and statistics upside down, it seems, and through the rosy glow of our own remembered college experiences. Perhaps college doesn’t make people intelligent, ambitious, happy, liberal, or quick to learn things—may it is just the other way around, and intelligent, ambitious, happy, liberal, quick-learning people are merely the ones who have been attracted to college in the first place. And perhaps all those successful college graduates would have been successful whether they had gone to college or not. This is heresy to those of us who have been brought up to believe that if a little schooling is good, more has to be much better. But contrary evidence is beginning to mount up.
1.According to the author, ___.
A.people used to question the value of college education.
B.people used to have full confidence in higher education.
C.all high school graduates went to college.
D.very few high school graduates chose to go to college.

A.high school graduates who aren’t suitable for college education.
B.college graduates who are selling shoes and driving taxis.
C.college students who aren’t any better for their higher education.
D.high school graduates who failed to be admitted to college.

A.young people are disappointed with the conventional way of teaching at college.
B.many people are required to join the army.
C.young people have little motivation in pursuing a higher education.
D.young people don’t like the intense competition for admission to graduate school.
4.According to the passage, the problems of college education partly originate in the fact that___.
A.society cannot provide enough jobs for properly trained graduates.
B.High school graduates do not fit the pattern of college education.

D.Intelligent people may learn quicker if they don’t go to college.

A controversy erupted in the scientific community in early 1998 over the use of DNA (deoxyribonucleic acid ) fingerprinting in criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.
DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.
The controversy in 1998 stemmed form a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.
In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions. And, in April, a National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.
1.Before DNA fingerprinting is used, suspects____.
A.would have to leave their fingerprints for further investigations
B.would have to submit evidence for their innocence
C.could easily escape conviction of guilt
D.cold be convicted of guilt as well
2.DNA fingerprinting can be unreliable when ____.
A.the methods used for blood- cell calculation are not accurate
B.two different individuals of the same ethnic group may have the same DNA fingerprinting pattern
C.a match is by chance left with fingerprints that happen to belong to two different individuals
D.two different individuals leave two DNA samples.
3.To geneticists like Lewontin and Hartl, the current method ____.
A.is not so convincing as to exclude the likelihood that two DNA samples can never come from two individuals
B.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.
C.Is not based on adequate scientific theory of genetics
D.Is theoretically contradictory to what they have been studying
4.The attitude of the Federal Bereau of Investigation shows that ____.
A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNA samples coming from two individual members
B.enough data of DNA samples should be collected to confirm that only DNA samples form the same person can match
C.enough data are yet to be collected from various ethnic groups to determine the likelihood of two different DNA samples coming form the same person
D.additional samples from various ethnic groups should be collected to determine that two DNA samples are unlikely to come from the same person
5.National Academy of Sciences holds the stance that ____.
A.DNA testing should be systematized
B.Only authorized laboratories can conduct DNA testing
C.The academy only is authorized to work out standards for testing
D.The academy has the right to accredit laboratories for DNA testing
