Some scientists now believe it to be a matter of biology, though many believe the answer cannot be wrapped up in such a neat little packet. Meaning: Some scientists now believe that human happiness is a

23、 biological matter, though many believe that the answer is not that simple.2. Geneticist John Hamer believes there are genes that make some people happier or sadder than others. Meaning: Geneticist John Hamer believes that there are genes that make some people happier while making some people sadder

24、.3. Hamer reviewed twin studies of this nature.Please notice the figurative use of "twin" in this sentence. "Twin" is a pun: on the one hand, it means that the objects of the study are twin brothers and sisters; on the other hand, it implies that there are two studies: one is on

25、identical twins and the other on twins who are not identical.4. In the first study, David Brown and George Yule a psychologist and a geneticist, respectively tried to measure happiness in 1,500 sets of twins, half of which were identical. Please notice that: "identical twins (同卵双胞胎)" are t

26、wins of the same sex who look exactly like each other. 5. Upon receipt of the completed surveys, it became clear that the responses, or happiness scores, of the twins who were not identical were almost no different than the responses of unrelated pairs of people. Meaning: The results of the survey s

27、howed clearly that the twins who were not identical gave the same responses, or got the same happiness scores, as those pairs of people who were not related.6. Since identical twins have genes that are complete copies of one another, the researchers believed this revealed a physical link to happines

28、s. Meaning: Because identical twins have exactly the same genes as each other, the researchers believed that this proved that happiness was a biological or physical matter.7. Hamer viewed the research on twins as strong proof that people's basic personality is a matter of biology, passed down as

29、 a row of interacting genes. Meaning: Hamer believed that the study of twins has strongly proved that people's basic personality is biological, passed down from parents to children in the form of genes that influence one another. 8. Likewise, medical researchers believe that depression and anxie

30、ty are caused by an imbalance of such chemicals, and often prescribe them in tablet form to patients who cannot produce enough.Meaning: Similarly, medical researchers believe that depression and anxiety occur because the amount of such chemicals is not balanced. So they often prescribe tablets to th

31、e patients who cannot produce enough of such chemicals.9. Many researchers believe that while the underlying ability to experience pleasure may be physical, much happiness can come from other things, such as family, friends, and accomplishments.Meaning: Many researchers believe that although the bas

32、ic ability to feel happiness may be related to genes, much happiness can come from other things, such as family, friends, and achievements.10. On the other hand, opponents of Hamer's theory note that any number of factors may have affected the researchers' studies, and warn against attaching

33、 great importance to these results. Meaning: On the other hand, those who are against Hamer's theory point out that many factors may have affected the researcher's studies, and warn people not to attach too much importance to these results.11. Others say that these studies provide a mere ske

34、tch of a much larger and complicated picture.Meaning: Others say that these studies only give a very simple description of a much greater and complicated situation.12. Research that has been done in prisons, nursing homes, and other places where people are highly controlled, has all conveyed the dep

35、ressing effects of a life without personal freedom.Meaning: Research that has been carried out in prisons, nursing homes, and other places where people are highly controlled, has all showed that a life without personal freedom has bad effects which make people depressed.13. Ultimately, torches still burn brightly on both sides of this debate, with no real settlement in sight.Meaning: Finally, the debates between the two sides will go on, with no possibility of reaching a conclusion in the near future.exerciseUSING THE RIGHT WORDC
