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.

     (17)_____, there are the uses of text-messaging as part of a treatment regime.

选项 A、rise
B、boost
C、produce
D、encourage
答案B
解析 整句话的理解。这一段的第二句举了英国的几项试验：短信提醒功能将手机用户同家庭医生的约会错过率降低了26%到39%，同医院的约会错过率则减少了33%到50%，由此可以推断编发短信可以提高工作效率，boost"增强(某事物)的力量，提高(某事物)的价值"符合题意。rise具有很大的迷惑性，它也有提高的含义，但其是不及物动词，后应接介词，所以排除。produce"生产"和encourage"鼓励"均不符合题意。
