河北省石家庄市2015高考英语 阅读、完形填空四月选练5阅读理解。阅读下列短文, 从给的四个选项 (a、b、c和d) 中, 选出最佳选项。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 agerelated 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 colour and betacarotene 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.4 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.2 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 agerelated diseases.d they can keep you in good health.3 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 effect on the skin.4 we can infer from the passage that _askins redness, yellowness and lightness make a person look more healthy and attractivebcarotenoids have the same effect as lycopenecit is carotenoids that give tomatoes and red peppers their red colourdboth betacarotene and polyphenols affect skin colour by causing blood rush to the skin

defense system against infection（感染）. doctors at brigham and womens hospital in boston, massachusetts, did the study. the team studied a chemical found in black, green, oolong and pekoe tea. this chemical is an amino acid（氨基酸）called l-theanine. the scientists say it may increase the strength of gamma delta t cells. thats the letter t, not the drink. gamma delta t cells are part of the bodys defenses.first, the researchers mixed some of these cells with antigens（抗原）found in the amino acid. antigens help the body react to infection. then the scientists added some bacteria（细菌）. within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. cells not mixed with the antigens did not produce interferon.in the second part of the study, eleven people drank five to six cups of black tea every day. ten other people drank the same amount of instant coffee. that is dried coffee mixed with hot water.two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. they also looked at what happened when they added bacteria to the blood cells. they found that the tea drinkers produced five times more interferon after they started drinking tea. the coffee drinkers did not produce interferon.doctor jack bukowski led the study. he says the antigens added to the gamma delta t cells were responsible for the increased reaction to the bacteria. he says the study also showed that the cells were able to remember the bacteria and fight them again the next time.earlier research already has found that tea can help prevent heart disease and cancer. doctor bukowski says the new study must be repeated with more people. if the findings prove to be true, he says, then tea drinking might also help protect against bacterial infections. he says the amino acid l-theanine could be removed from tea and used as a drug to strengthen the bodys defenses.1. we may know from the text that _ can be found in different kinds of tea.a. gamma delta t cellsb. l-theaninec. interferond. bacteria 答案解析：答案为b。本题为推理题。由第一段 “the team studied a chemical found in black, green, oolong and pekoe tea. this chemical is an amino acid called l-theanine.” 可知，在black, green, oolong and pekoe tea里面发现了叫做l-theanine的化学成分。故答案为b。2. tea may help strengthen the bodys defense system because it helps _.a. the body to produce more interferon b. the body to produce more gamma delta t cellsc. to add some bacteria to the blood cells d. to mix antigens with some of the cells in the body答案解析：答案为a。本题为推理题。由第二段 “within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection.” 可知，细胞产生interferon，它可以抵抗感染，故可推断，茶能增强身体的抵抗能力因为它能帮助身体产生更多的interferon。故答案为a。3. according to dr bukowski, _.a. the findings of the study have already proved to be trueb. he has taken some amino acid l-theanine from tea and made a drug with itc. further study is needed to prove the findings true来源:d. he is not sure whether tea can help prevent heart disease and cancer 答案解析：答案为c。本题为推理题。由最后一段首句 “earlier research already has found that tea can help prevent heart disease and cancer.” 可知，d选项错误。由该段的后文 “doctor bukowski says the new study must be repeated with more people. if the findings prove to be true”可知，a选项错误，c选项正确。由最后一句 “he says the amino acid l-theanine could be removed from tea and used as a drug to strengthen the bodys defenses.” 可知，dr bukowski认为可以从茶中提取amino acid l-theanine来制药，b选项与文意不符，故错误。4. what would be the best title for this text?a. tea is better than coffee.b. tea may help fight infectionc. tea can help prevent cancer.d. our body needs tea 答案解析：答案为b。全文都是围绕第一段首句 “american researchers say drinking tea may help strengthen the bodys defense system against infection.” 展开，故标题为b选项。完形填空。i tend to accept any idea put forward by experts on tv. one day，a sociologist proposed that the _1_ society has been consuming modern humans little by little. for fear that i would
