问题 单项选择题

维生素E是一种溶解于油中的维生素,它是一种抗氧化剂,能清除氧自由基,从而保护细胞膜上的脂质,而脂质的氧化与冠心病、癌症、衰老等密切相关,总之,维生素E是人体不可缺少的营养成分,但是“需要”并不意味着越多越好。维生素E缺乏在人群中很少发生,只有几种人可能存在问题:胆法缺乏或脂肪代谢困难的人;罕见的基因异常导致缺乏维生素E转移蛋白的人;因早产而体重严重不足的婴儿,这些情况在人群中都不易出现。 这段文字所传达的观点是:

A.正常人没必要补充维生素E 

B.应该正确认识维生素E的作用 

C.人们对维生素E的认识存在误区 

D.要特别注意可能缺乏维生素E的人

答案

参考答案:A

解析:解析 根据提问可知本题属于表面主旨题。 文段前两句介绍了维生素E的定义和作用,得出维生素对人体必不可少的结论。接下来,由关联词“但是”的转折作用可知,文段后半部分更为重要。后半部分阐述了维生素E的需要量较少,而缺乏的情况在人群中不易出现,可以推知,大部分人是不缺乏维生素E的,也就没有补充的必要,故正确答案为A。 B项的叙述正确,但不是文段重点;C项从文段中找不到依据,属于无中生有,D项则延伸过度。 考点:表面主旨题
