问题 Which of the following can be concluded from the first paragraph?
Which of the following may best Summarize the text?

选项 A、People shouldn’t worry about the supposed ill effects of mobile phones.
B、Text-messaging should be widely used in all walks of life.
C、Conventional treatment should be supplanted by new treatments.
D、The medical uses of mobile phones show the healthy benefits.

答案D

解析本题是主旨题。本文开篇由问句引出人们有关“手机对人类健康影响”的观点：负面影响缺乏可靠证据；对健康有益的证据越来越多．之后提到Rifat Atun汇总的“150条手机短信用于提供医疗保健服务的事例”。然后指明短信的三种用途，并本别在第二，三段、第四段、第五段对这三种用途进行具体说明。第五段第三句指出“有关这些作用效果的例证一般都是道听途说来的，尚需进一步定量研究——这也正是里法特研究小组本周着眼于阐明手机对卫生保健的作用所发表的3篇论文的出发点”，之后对他们的定量研究进行了具体说明。由此可见，本文结构是总分结构，开篇提出主题，然后分项进行阐述，因此主旨就是首段提到的the beneficial effects of mobile phones on health，后面内容是用“手机短信对健康的作用”来论证该论点的，故 [D]为答案．本文只论证了“手机对健康的好处”，没有说明对健康的负面影响，排除[A]。末段提到“短信的很多医疗用途由于太过新颖，还没有接受临床试验，即便是已被证实的用途，也尚未得到系统性推广”，但本文只是谈到医疗领域，并未涉及其他领域，[D]中的all walks of life(各行各业)为过度推断。此外，conventional treatment是作者在介绍定量研究“少年糖尿病患者的”实验中提到的细节，非主旨，排除[C]。
