    As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.
    Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use information in a different way.One of the world's great thinkers and scientists,Albert Einstein was dyslexic.Einstein said that he never thought in words the way that most people do.He said that he thought in pictures instead.The American inventor Thomas Edison was also dyslexic.Dyslexia first was recognized in Europe and the United States more than 80 years ago.Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia are different.In most people,the left side of the brain一 the part that controls language is larger than the right side.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes this difference.However,research has shown that dyslexia is more common in males than in females,and it is found more often in persons who are left handed.No one knows the cause of dyslexia,but some scientists believe that it may result from chemical changes in a baby's body long before it is born.They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help.After they have solved their problems with language,they often show themselves to be especially intelligent or creative.

    Generally speaking,dyslexia is more common in left-handed males than in right-handed females.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:A
    解析:
    该题提到数字的问题,所以注意文章中含有数字的句子。文章第一段提到:"As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.”美国有多达20%的儿童患有阅读障碍症。问题句中的one out of five的意思是“每五个人中有一个”,即20%的人。
    问题句说“世界上许多伟大的思想家和科学家都患有阅读障碍症。”文章第二段仅提到爱因斯坦和爱迪生是阅读障碍症患者,并未讲许多科学家和思想家也有这种情况。因此选C。
    利用the first cases作为答案线索词,在第二段找到答案所在句:" Dyslexia first was recognized in Europe and the United States more than 80 years ago.”该句说欧洲和美国在80多年以前首次发现阅读障碍症患者,与问题句The first cases of dyslexia in Europe were discovered less than a century ago吻合。
    注意含有“the left side of the brain/the right side of the brain”的句子,可以在第二段找到答案,相关句说:" In persons with dyslexia , the right side of the brain is bigger.”患阅读障碍症的人的右脑比左脑大。所以该题选B。
    注意文章中含有“the left handed/the right handed”的句子。找到答案相关句:“…research has shown that dyslexia is more common in males than in females,and it is found more often in persons who are left handed.”该句说有研究表明男人比女人更易患阅读障碍症,惯用左手者比惯用右手者更易患阅读障碍症,据此我们可以推断该句子是正确的。
    通读全文,根本就找不到关于“婴儿母亲的不良习惯”的信息。况且文章说阅读障碍的成因尚不清楚,因此选C。
    根据intelligent和creative,我们在文章最后一句话找到答案相关句:" After they have solved their problems with language,they often show themselves to be especially intelligent or creative.”该句说解决了语言方面的问题之后,患有阅读障碍症的人往往表现出超人的智慧或创造力。
