问题     What impact can mobile phones have on their users’ health? Many people worry about the supposed ill effects caused by radiation from handsets and base stations, (1)_____ the lack of credible evidence of any harm. But evidence for the beneficial effects of mobile phones on health is rather more (2)_____ Indeed, a systematic review (3)_____ out by Rifat Atun and his colleagues at Imperial College, rounds up 150 (4)_____ of the use of text-messaging in the (5)_____ of health care. These uses (6)_____ three categories: efficiency gains; public-health gains; and direct benefits to patients by (7)_____ text-messaging into treatment regimes.
    Using texting to (8)_____ efficiency is not profound science, but big savings can be achieved. Several (9)_____ carried out in England have found that the use of text-messaging reminders (10)_____ the number of missed appointments with family doctors by 26-39%, and the number of missed hospital appointments by 33-50%. If such schemes were (11)_____ nationally, this would translate (12)_____ annual savings of ￡256-364 million.
    Text messages can also be a good way to deliver public-health information, particularly to groups (13)_____ are hard to reach by other means.

     (17)_____, there are the uses of text-messaging as part of a treatment regime. These involve sending reminders to patients to (18)_____ their medicine, or to encourage accordance with exercise regimes. However, Dr. Rifat notes that the evidence for the effectiveness of such schemes is generally (19)_____, and more quantitative research is (20)_____.

选项 A、unscientific
B、real
C、anecdotal
D、legal
答案C
解析 However表转折，说明有关这些手机短信作用效果的例证还不完全可信，anecdotal"多趣闻轶事的，轶事一样的"，如：His findings are based on anecdotal evidence rather than serious research．他的发现只是基于粗浅的证据，而不是严肃的研究。anecdotal evidence在心理学上称为"轶事证据"，即粗浅的证据，经常以故事形式出现：比如"我记得那时…"，"我听说…"，这种证据通常不准确、不可靠，故anecdotal符合题意。unscientific"不科学的"虽然放进句子中也通顺，但需要进一步的定量研究，去证明这些作用是否科学，而不是过早地下定论，故排除。如选real"真实的"或legal"合法的"，说明有关这些作用效果的例证是真实的或是合法的，而这样的例证是不需要进一步定量研究的，故二者不符合题意，排除。
