        Food and Cancer
            Medical Experts have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of developing cancer. A team of Chinese and American scientists did the study. They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study. They were form the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.
            Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus. Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate. Researchers divided those into eight groups. Seven of the groups received different mixtures of vitamins and minerals daily. The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed. The eighth group received sugar pills that had no effect. Those who seemed to fain the most received a mixture of a form of vitamin A called ß-carotene, vitamin E and the mineral selenium. The vitamin and mineral are believed to prevent damage to cells caused by cancer-causing substances. Researchers reported a 13 percent drop in cancer rates in those who took ß-carotene, vitamin E and selenium. They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels.
            Scientists warn that it is too soon to know if the effect would be the same among people in other countries. They note that the people in Linxian eat foods that lack necessary vitamins and minerals. Chinese officials will continue to record the health records of the people in Linxian for many years. For now officials reportedly are considering using the results of the study. They want to find a way to improved the health of people in Linxian and other small towns in China.

            參考答案:
            1. B。分析問題句:問題句說:新的研究結(jié)果出乎人們的意料之外。
            確認(rèn)線索詞:new study, 因為該詞是句子中的核心詞。
            答案相關(guān)句:
            Medical Experts have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of developing cancer. 該劃線句說“他們(醫(yī)學(xué)專家)一項新的研究提供了第一個證據(jù)..”,該句前面說“醫(yī)學(xué)專家很多年一直懷疑人們的飲食和癌癥之間有直接的聯(lián)系”,因此可見新的研究結(jié)果不是意料之外,而是意料之中的。
            2. C.分析問題句:問題句說:在做那項研究的科學(xué)家中,中國人比美國人多。
            確認(rèn)線索詞:Chinese 和 American, 因為它們是句子中的核心詞,也是特征詞。
            答案相關(guān)句:
            A team of Chinese and American scientists did the study. They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study. They (30000名研究對象)were from the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.
            包含到線索詞的句子和周圍的句群都沒有涉及到美國科學(xué)家和中國科學(xué)家人數(shù)的比較,因此判斷問題句的說法為“沒提到”。
            3. A。分析問題句:問題句說:研究持續(xù)了大約5個小時。
            確認(rèn)線索詞:five years,因為該詞是特征詞。
            答案相關(guān)句:
            They were from the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.該句說“大部分研究對象每天服用維他命和礦物質(zhì),服用了5年”,因此可以推斷出“研究持續(xù)了大約5年”。
            4. C。分析問題句:問題句說:寧夏胃癌和食道癌的發(fā)生率是中國的。
            確認(rèn)線索詞:cancer of stomach and esophagus (食道),因為該短語是特征結(jié)構(gòu)。
            答案相關(guān)句:
            Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus. 該句只是說“寧夏胃癌和食道癌的發(fā)生率是極高的”,并沒有說是中國的,而后句(Researchers believe that fungus(菌類) and molds(霉) in local foods may be partly responsible for the high cancer rate./該句講述造成胃癌和食道癌的高發(fā)生率的原因)引出的是新的話題,沒有進(jìn)行胃癌和食道癌的發(fā)生率的比較,因此判斷問題句的說法為“沒提到”。
            5.A.分析問題句:問題句說:當(dāng)?shù)厥澄镏械木惡兔咕赡苁窃斐蓪幭陌┌Y高發(fā)率的原因。
            確認(rèn)線索詞:Fungus 和 molds,因為它們是特征詞語
            答案相關(guān)句:
            Researchers believe that fungus(菌類) and molds(霉) in local foods may be partly responsible for the high cancer rate.該句的說法與問題句的說法一致。
            6. B。 分析問題句:問題句說:所有參加研究的人都服用維他命和礦物質(zhì)
            確認(rèn)線索詞:vitamins and minerals, 因為它們是該句的核心詞。
            答案相關(guān)句:
            Researchers divided those into eight groups. Seven of the groups received different mixtures of vitamins and minerals daily. The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed. The eighth group received sugar pills that had no effect. 原文說“研究對象有8組,其中7組每天服用維生素和礦物質(zhì),而第8組服用的是對健康沒有影響的糖丸”,因此可見“不是所有的研究對象都服用維他命和礦物質(zhì)”,所以問題句的說法錯誤。
            7. B。分析問題句:問題句說:研究結(jié)果對世界各地的人都具有很大的意義。
            確認(rèn)線索詞:因為該句是概括總結(jié)句,所以很可能與該句相關(guān)的內(nèi)容會在文章中間接的出現(xiàn),而且因為該句是談及研究的意義,因此推斷答案相關(guān)句很可能會出現(xiàn)在文章的最后部分。
            答案相關(guān)句:
            (最后一段) Scientists warn that it is too soon to know if the effect would be the same among people in other countries. 該句說“目前太早了還不能知道是否這個影響對其他國家的人們是一樣”.. (最后一句)They want to find a way to improved the health of people in Linxian and other small towns in China. 在最后一句中提到仍然是寧夏和中國的其他小城市的問題。因此判斷問題句的說法不正確。
