第三篇 IQ-gene In the angry debate over how much of IQ comes from the genes that children inherit from parents and how much comes from experiences, one little fact gets overlooked: no one has identified any genes (other than those that cause retardation) that affect intelligence. So researchers led by Robert Plomin of London’s Institute of Psychiatry decided to look for some. They figured that if you want to find a "smart gene", you should look in smart kids. They therefore examined the DNA of students like those who are so bright that they take college entrance exams four years early--and still score at Princeton--caliber levels. The scientists found what they sought. "We have," says Plomin, "the first specific gene ever associated with general intelligence." Plomin’s colleagues drew blood from two groups of 51 children each, all 6 to 15 years old and living in six counties around Cleveland. In one group, the average IQ is 103. All the children are white. Isolating the blood cells, the researchers then examined each child’s chromosome 6 of the 37 landmarks on chromosome 6 that the researchers looked for, one jumped out: a form of gene called IGF2R occurred in twice as many children in the high-IQ group as in the average group--32 percent versus 16 percent. The study, in the May issue of the journal Psychological Science, concludes that it is this form of the IGF2R gene that contributes to intelligence. Some geneticists see major problems with the IQ-gene study. One is the possibility that Plomin’s group fell for "chopsticks fallacy". Geneticists might think they’ve found a gene for chopsticks flexibility, but all they’ve really found is a gene more common in Asians than, say, Africans. Similarly, Plomin’s IQ gene might simply be one that is more common in groups mat emphasize academic achievement. "What is the gene that they’ve found reflects ethnicity" asks geneticist Andrew Feinberg of Johns Hopkins University. "That alone might explain the link to intelligence, since IQ tests are known for being culturally sensitive and affected by a child’s environment. "And Neil Risch of Standford University points out that if you look for 37 genes on a chromosome, as the researchers did, and find that one is more common in smarter kids, that might reflect pure chance rather than a causal link between the gene and intelligence. Warns Feinberg, "I would take these findings with a whole box of salt." In the beginning of paragraph one we are told that scientists can not agree______.
A. how much of IQ comes from intelligence
B. how many children inherit genes from parents
C. how much of IQ comes from genes
D. how many children learn by experience
阅读下面的短文,文中有15处空白,每处空白给出了4个选项,请根据短文的内容从4个选项中选择1个最佳答案。 Scientists Develop Ways of Detecting Heart Attack German researchers have (1) a new generation of defibrillators and early warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest. In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart’s rhythm. Those most at risk are Patients who have (4) suffered a heart attack and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions such as that of pacemaker. Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with all implanted defibrillator (7) of generating a six-channel electrocardiogram(ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders the evaluation of ECG data (9) . The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only (11) into account a linear correlation of the data. We are, however, making use (12) a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system." Hagen Knaf says." (13) changes in the heart beats over time can be monitored and individual variations in patients taken into account." An old study of ECG data, based (14) 600 Patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show (15) the new software evaluates the data considerably better.
