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

Hello there,

     I'm writing to ask you for help.It's really urgent because I'm considering running away from

home.I feel like there's no way to fix the problem with my mother.

     Yesterday evening,we had a heated argument at home after I got home a bit late again.

     I had been at my friend's birthday party.I'd explained it to her but she just didn't believe me.

    I do know my mother loves me very much and she wants me around every day,or even every

minute.

     But the fact is that I am 17 years old and I have my own life style.I am my parents' only child

and my mother says she wants me to have the best possible chance of happiness in the future.

She is always telling me to behave well when I leave home or go out.What's worse,whenever

there is a cold war between my mother and me,my father often keeps silent.I am not only

confused but also hurt.I don't know what to say or what to do to make things right.I think they

are out of fashion and too old to know my inner part.

     To tell the truth,I have packed up my backpack but am still at a loss.

                                                                                                                               Kate
