2014高考英语阅读理解基础全程训练(3)及答案较难题目特训:科普知识类you know eating fruit and vegetables does good. but do you know it can also make you look good? people who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. scientists at st andrews university found eating them slightly increased yellow and red pigments in the volunteers skin. they monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. increasing their intake of greens by 2.9 portions a day was found to make the person look more healthy and an extra 3.3 portions could enhance their attractiveness, when their photographs were rated by others.fruit and vegetables are rich in carotenoids(类胡萝卜素),which are known to protect against cell damage from pollution and uv rays, and can also prevent age-related diseases including heart disease and cancer. but while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange,it was not known a small increase was perceptible(被觉察)to othersand was seen as appealing.a camera measured changes to the skins redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. these changes were not evident in three weeks. using light sensors, the researchers showed these red and yellow hues were linked with the levels of carotenoids in their skin. there are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene(番茄红素)which gives tomatoes and red peppers their red colourand beta-carotene found in carrots as well as broccoli, squash, and spinach. skin colour is also affected by chemicals called polyphenols(多元酚),found in apples, blueberries and cherries, which cause blood rush to the skin surface.31. what do we know from the research?a. if you take in a little more fruit and vegetables, you will obviously look more attractive in three weeks.b. the researchers took the pictures of the 35 people in the research at different stages.c. increasing your intake of greens by 2.9 portions a day can greatly improve your health.d. people who increased their intake of greens by 3.3 portions a day were found the most attractive after six weeks.32. which of the following is not the function of carotenoids?a. they can protect against cell damage from pollution and uv rays.b. they can prevent heart disease and cancer.c. they can prevent age-related diseases.d. they can keep you in good health.33. which of the statements is not true according to the passage?a. weve already known eating extreme amounts of carrots can turn skin orange.b. we knew in the past that eating a few more carrots could make us look appealing.c. the research showed the improvement in skin is linked with the levels of carotenoids in it.d. among hundreds of carotenoids, lycopene is thought to have the most dramatic 34. we can infer from the passage that _.a. skins redness, yellowness and lightness make a person look more healthy and attractiveb. carotenoids have the same effect as lycopenec. it is carotenoids that give tomatoes and red peppers their red colourd. both beta-carotene and polyphenols affect skin colour by causing blood rush to the skin surface35. which can be the best title of the passage?a. eating fruit and vegetables does good. b. fruit and vegetables are rich in carotenoids. c. how to become attractive?d. eating fruit and vegetables makes you look good.【参考答案】3.31-35 bdbad阅读理解-amost musicians agree that the best violins were made in italy. they were made in cremona, italy, about 200 years ago. these violins sound better than any others. they even sound better than violins made today. violin makers and scientists try to make instruments like the old italian violins. but they arent the same. musicians still prefer the old ones. no one really knows why these old italian violins are so special, but many people think they have an answer.some people think it is the age of the violins. they say that todays violins will also sound wonderful someday. but there is a problem here. not all old violins sound wonderful. only those from cremona are special. so age cannot be the answer. there must be something different about cremona or those italian violins makers.other people think the secret to those violins is wood. the wood of the violin is very important. it must be from certain kinds of the trees. it must not be too young or too old. perhaps the violin makers of cremona knew something special about wood for violins.but the kind of wood may not be so important. it may be more important to cut the wood in a special way. wood for a violin must be cut very carefully. it has to be the right size and shape. the smallest difference will change the sound of the violin. musicians sometimes think that this was the secret of the italians. maybe they understood more than we do about how to cut the wood.size and shape may not be the answer either. scientists measured these old violins very carefully. they can make new ones that are exactly the same size and shape. but the new violins still do not sound as good as the old ones. some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny. it also helps the sound of the instrument. no one knows what the italian violin makers used in their varnish. so no one can make the same varnish today.there may never be other violins like the violins of cremona. their secret may be lost forever. young musicians today hope this is not true. they need fine violins. but there arent very many of the old violins left. also, the old violins are very expensive. recently, a famous old italian violin was sold for about us$300,000!1. this passage is about . a. making violinsb. musical instrumentsc. scientific ideasd. the old italian voilins答案解析:答案为d。本题为主旨大意题。 第一段最后一句话 “no one really knows why these old italian violins are so special, but many people think they have an answer.” 引入话题,为什么古老的意大利小提琴如此特别,很多人认为他们知道答案,后文分别给出了不同人的答案,最后一段对问题的答案进行总结 “there may never be other violins like the violins of cremona. their secret may be lost forever.” 意大利小提琴的秘密或许永远消失了,无人知晓。全文都是围绕古老的意大利小提琴展开。故答案为d。2. the best violins .a. are made with modern techniquesb. were lost many years agoc. were made in italy 200 years ago d. were made by scientists答案解析:答案为c。本题为细节题。由第一段第一、二句话 “most musicians agree that the best violins were made in italy. they were made in cremona, italy, about 200 years ago.” 可知,答案为c。3. some people think that modern violins .a. will sound better in the futureb. will sound worse in the futurec. sound wonderful and naturald. will never be as old as those from cremona答案解析:答案为a。本题为细节题。结合第二段和该段第二句话 “they say that todays violins will also sound wonderful someday.” 可知,一些人认为现代小提琴有一天也会演奏出优美的旋律,故a选项正确。b、c选项与文意不符,d选项未提及。4. violins made today . a. look the same as the old onesb. sound the same as the old onesc. are better than the old onesd. have the same varnish as the old ones答案解析:答案为a。本题为推理题。由倒数第二段 “they can make new ones that are exactly the same size and shape. but the new violins still do not sound as good as the old ones.” 可知,科学家可以制作出和意大利小提琴一样大小和形状的小提琴,但是新的小提琴音质就是不如意大利小提琴好,故a正确,b、c错误。由该段最后两句话 “no one knows what the italian violin makers used in their varnish. so no one can make the same varnish today.”可知,d选项错误。社会生活类when women sit together to watch a movie on tv, they usually talk simultaneously(同时地) about a variety of subjects, including children, men, careers and whats happening in their lives. when groups of men and women watch a movie together, the men usually end up telling the women to shut up. men can either talk or watch the screenthey cant do bothand they dont understand that women can. besides, women consider that the point of all getting together is to have a good time and develop relationshipsnot just to sit there like couch potatoes staring at the screen. during the ad breaks, a man often asks a woman to explain the plot and tell him where the relationship between the characters is going. he is unable, unlike women, to read the subtle body language signals that reveal how the characters are feeling emotionally. since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully in order to maintain relationships. for a woman, speech continues to have such a clear purpose:to build relationships and make friends. for men, to talk is to relate the facts. men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a means of bonding. a woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours. there is no convincing evidence that social conditioning, the fact that girls mothers talked to them more, is the reason why girls talk more than boys. psychiatrist dr michael lewis, author of social behaviour and language acquisition, conducted experiments that found mothers talked to, and looked at, baby girls more often than baby boys. scientific evidence shows parents respond to the brain bias of their children. since a girls brain is better organized to send and receive speech, we therefore talk to them more. consequently, mothers who try to talk to their sons are usually disappointed to receive only short grunts in reply. 1. while watching tv with others, women usually talk a lot because they.a. are afraid of awkward silence with their families and friendsb. can both talk and watch the screen at the same timec. think they can have a good time and develop relationshipsd. have to explain the plot and body language to their husbands2. after a vacation with her girlfriend, a woman would talk to her again on the phone for hours in order to.a. experience the happy time againb. keep a close tie with herc. recommend her a new scenic spotd. remind her of something forgotten3. what does the author want to tell us most? a. womens brains are better organized for language and communication. b. women love to talk because they are more sociable than men.c. men do not like talking because they rely more on facts.d. social conditioning is not the reason why women love talking.4. which of the following would be the best title for the passage? a. women are socially trained to talkb. talking maintains relationshipsc. women love to talkd. men talk differently from women【参考答案】59.1-4 cbac 阅读理解-bare you preparing for a big test? if so, you may want to go play some basketball in between hitting the books. doctors are starting to find more and more information that suggests a connection between exercise and brain development. judy cameron, a scientist at oregon health and science university, studies brain development. according to her research, it seems that exercise can make blood vessels(血管), including those in the brain, stronger and more fully developed. doctor cameron is sure that this allows people who exercise to think better. as she says, “ while we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”the effects of exercise on brain development can even be seen in babies. babies who do activities that requires a lot of movement and physical activity show greater brain development than babies who are less physically active. even a little movement can show big results. margaret barnes, a scientist, also believes in the importance of exercise. she thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. “babies need movement that encourages and excites their five senses. they need to set up a connection between motion and memory. in this way, as they get older, children will begin to connect physical activity with higher learning,” says margaret.older people can develop their brains as well. cornell university studied a group of seniors who have a shortterm memory increase of up to 40 percent after exercising just three hours a week. the exercise does not have to be very difficult, but it does have to increase the heart rate. also, just like the motion for babies, exercise for older people should not be too simple. learning some new skills or actions, such as with yoga or tai-chi helps to open up memory paths in the brain that may not have been used for a long time. for most people, any type of physical activity that increases the heart rate is helpful. the main aim is to increase the brains flow of blood. and your brain can benefit from as little as two to three hours of exercise a week.1. what is the main idea of this passage?a. how exercise makes people strong.b. how to get good scores on a test.c. how exercise helps the brain.d. how the brain can change. 答案解析:答案为c。本题为主旨大意题。第一段就点出了全文的中心 “according to her
