2、 dont read any of the other questions.直接看第一道题目，不要浪费时间读完全文或每一段的第一句，也不要读其它题目。2. do paragraph questions last. questions that ask you to match headings or statements with paragraphs are much easier if you are already familiar with the passage.最后做匹配段落标题题型。当你对整篇*内容比较了解的时候标题配对题会更加容易。3. dont get stuck on on

3、e question. as soon as you realise that you are having difficulties with a question, leave it and move to the next one. return to difficult questions later if you have time.不要卡在一道题上。一觉得这道题目很难，就放下它去做下一道。如果最后还有时间的话再来做难题。4. remember that the answers to most question sections are in order in the passage

4、. you dont need to go back to the beginning of the passage to search for each answer.记住大多数问题答案都是按顺序在*中出现的。你不用从头开始找每道题。5. only skim or scan for numbers and names. otherwise, read at normal speed.略读或扫读*和名字，其余部分都用正常速度阅读。6. work with an alarm. you cant do this in an exam, but at home you could set the a

5、larm (on your phone) for 2 minutes and try to do each question within this time.学习的时候要使用闹钟。你在考试的时候不允许带闹钟，但是在家你可以给自己设定做一道题目的时间是两分钟，在这个时间之内找到答案。雅思阅读机经真题解析-twin study: two of a kindyou should spend about 20 minutes on question 14-26 which are based on reading passage below.athe scientific study of twin

6、s goes back to the late 19th century, when francis galton, an early geneticist, realized that they came in two varieties: identical twins born from one egg and non-identical twins that had come from two. that insight turned out to be key, although it was not until 1924 that it was used to formulate

7、what is known as the twin rule of pathology, and twin studies really got going.bthe twin rule of pathology states that any heritable disease will be more concordant (that is, more likely to be jointly present or absent) in identical twins than in non-identical twinsand. in turn, will be more concord

8、ant in non-identical twins than in non-siblings. early work, for example, showed that the statistical correlation of skin-mole counts between identical twins was 0.4, while non-identical twins had a correlation of only 0.2. (a score of 1.0 implies perfect correlation, while a score of zero implies n

9、o correlation.) this result suggests that moles are heritable, but it also implies that there is an environmental component to the development of moles, otherwise the correlation in identical twins would be close to 1.0.ctwin research has shown that whether or not someone takes up smoking is determi

10、ned mainly by environmental factors, but once he does so, how much lie smokes is largely down to his genes and while a persons religion is clearly a cultural attribute, there is a strong genetic component to religious fundamentalism. twin studies arc also unraveling the heritability of various aspec

11、ts of human personality. traits from neuroticism and anxiety to thrill- and novelty-seeking all have large genetic components. parenting matters, but it does not determine personality in the way that some had thought.dmore importantly, perhaps, twin studies arc helping the understanding of diseases

12、such as cancer, asthma, osteoporosis, arthritis and immune disorders. and twins can be used, within ethical limits, for medical experiments. a study that administered vitamin c to one twin and a placebo to the other found that it had no effect on the common cold. the lesson from all todays twin stud

13、ies is that most human traits are at least partially influenced by genes. however, for the most part, the age-old dichotomy between nature and nurture is not very useful. many genetic programs are open to input from the environment, and genes arc frequently switched on or off by environmental signal

14、s. it is also possible that genes themselves influence their environment. some humans have an innate preference for participation in sports. others are drawn to novelty. might people also be drawn to certain kinds of friends and types of experience? in this way, a persons genes might shape the envir

15、onment they act in as much as the environment shapes the actions of the genes.ein the past, such research has been controversial. josef mengele, a nazi doctor working at the auschwitz extermination camp during the second world war, was fascinated by twins. he sought them out among arrivals at the ca

16、mp and preserved them from the gas-chambers for a series of brutal experiments. after the war, cyril burt, a british psychologist who worked on the heredity of intelligence, tainted twin research with results that appear, in retrospect, to have been rather too good. some of his data on identical twi

17、ns who had been reared apart were probably faked. in any case, the prevailing ideology in the social sciences after the war was marxist, and disliked suggestions that differences in human potential might have underlying genetic causes. twin studies were thus viewed with suspicion.fthe ideological pe

18、ndulum has swung back; however, as the human genome project and its aftermath have turned genes from abstract concepts to real pieces of dna. the role of genes in sensitive areas such as intelligence is acknowledged by all but a few die-hards. the interesting questions now concern how nature and nur

19、ture interact to produce particular bits of biology, rather than which of the two is more important twin studies, which are a good way to ask these questions, are back in fashion, and many twins are enthusiastic participants in this research.gresearch at the twinsburg festival began in a small way,

20、with a single stand in 1979. gradually, news spread, and more scientists began turning up. this year, half a dozen groups of researchers were lodged in a specially pitched research tent. in one corner of this tent. paul breslin, who works at the monell institute in philadelphia, watched over several

21、 tables where twins sat sipping clear liquids from cups and making notes. it was the teams third year at twinsburg. dr breslin and his colleagues want to find out how genes influence human perception, particularly the senses of smell and taste and those (warmth, cold, pain, tingle, itch and so on) t

22、hat result from stimulation of the skin. perception is an example of something that is probably influenced by both genes and experience. even before birth, people are exposed to flavours such as chocolate, garlic, mint and vanilla that pass intact into the bloodstream, and thus to the fetus. though

23、it is not yet clear whether such pre-natal exposure shapes taste-perception there is evidence that it shapes preferences for foods encountered later in life.hhowever, there are clearly genetic influences at work, as wellfor example in the ability to taste quinine. some people experience this as inte

24、nsely bitter, even when it is present at very low levels. others, whose genetic endowment is different, are less bothered by it. twin studies make this extremely clear. within a pair of identical twins, cither both, or neither, will find quinine hard to swallow. non-identical twins will agree less f

25、requently.ion the other side of the tent dennis drayna, from the national institute on deafness and other communication disorders, in maryland, was studying hearing. he wants to know what happens to sounds after they reach the car. it is not clear, he says, whether sound is processed into sensation

26、mostly in the ear or in the brain. dr drayna has already been involved in a twin study which revealed that the perception of musical pitch is highly heritable. at twinsburg, he is playing different words, or parts of words, into the left and right ears of his twinned volunteers. the composite of the

27、 two sounds that an individual reports hearing depends on how he processes this diverse information and that, dr drayna believes, may well be influenced by genetics.jelsewhere in the marquee, peter miraldi, of kent state university in ohio, was trying to find out whether genes affect an individuals

28、motivation to communicate with others. a number of twin studies have shown that personality and sociability arc heritable, so he thinks this is fertile ground. and next to mr. miraldi was a team of dermatologists from case western reserve university in cleveland. they are looking at the development

29、of skin diseases and male-pattern baldness. the goal of the latter piece of research is to find the genes responsible for making mens hair fall out.kthe busiest part of the tent, however, was the queue for forensic-science research into fingerprints the origins of this study are shrouded in mystery
