There are two types of twins: identical and non-identical twins. Identical twins are formed from a single egg in mother's body which divides to form. two separate babies. Identical twins look the same and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs at the same time, both of which grow to form. babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.There is a third type of twins, but it is a very unusual one. Twins who are joined together at birth are known in western countries as Siamese twins.(1)It is difficult to tell identical twins because ____________.A、they are dressed in the same clothesB、they are dressed in the same colorC、they are very alikeD、they are standing side by side(2)If the twins are easy to tell from each other, they are ____________.A、very probably non-identical twinsB、surely non-identical twinsC、surely identical twinsD、always a brother and a sister(3)Which of the following is NOT true according to this passage?A、In the 1970s and 1980s a scientist did some research into the two main types of twins.B、In the week of tests, he tested their speed of thinking, their speech, their memory and some other things.C、There were twins who had been separated from each other as soon as they were born.D、Very often, separated twins were found to choose things of the same kind, the same shape and the same color.(4)According to the passage, how many types of twins are there actually?A、oneB、twoC、threeD、four(5)This passage mainly tells us ____________.A、the main types of twinsB、what has been found out about twinsC、how twins are formedD、how a scientist studied twins

Passage TwoThere are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual the sort of environment in which he is reared (抚养). If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster (收养) homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's IQ was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.36. This selection can be titled ______.A. Measuring Your IntelligenceB.

第一篇UlcersEven though ulcers appear to run in families,lifestyle plays more of a role than genetic （基因的）factors in causing the illness, according to a report in the April 13th issue of Journal of Internal Medicine. In particular,smoking and stress in men and the regular use of pain-releasing medicines in women were linked with an increased risk of developing an ulcer（溃疡）.Overall,61% of ulcer risk appears to be due to environmental factors,such as smoking,and the remaining 39% is due to genes,according to Dr. lsmo Raiha of the University of Turkey and colleagues at the University of Helsinki,Finland.Some researchers had suggested that families may spread Helicobacteria pyloni（幽门螺旋菌）, the bacteria（细菌）that can cause ulcers. However, the new study suggests this is unlikely,according to the report.Raiha and colleagues studied data from more than 13,000 pairs of twins to examine the roles of genetic and environmental factors in the origin of ulcer. Both twins were more likely to develop an ulcer if the pain were genetically the same as compared with a pair of fraternal（由两受精卵发育而成的）twins , suggesting that there must be some genetic susceptibility（敏感性）to ulcer development.However,the risk was no greater in twins living together compared with twins living apart,suggesting that shared exposure to H.pyloni was not to blame." Environmental effects were not due to factons shared by family members,and they were related to smoking and stress in men and the use of pain-releasing medicines in women,"the authors write in their report. In the last paragraph,the word"suggesting"could be best replaced byA:assuming. B:implying.C:proposing. D:believing.

There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.
The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college.

问答题Practice 9 Think carefully about the issue presented in the following excerpt and the assignment below. How valuable is history for our generation? On the surface this question is not as easy as it once might have been, for there is a widespread belief that history may no longer be relevant to modem life. We live, after all, in an age that appears very different from the world that came before us. Adapted from Stephen Vaughn, History: Is It Relevant? Assignment: Is knowledge of the past no longer useful for us today? Plan and write an essay in which you develop your point of view on this issue. Support your position with reasoning and examples taken from your reading, studies, experience, or observations.
