问题 All specialists agree that the most important consideration with diet drugs is carefully ______ the risks and benefits.

选项 A、valuing
B、evaluating
C、estimating
D、weighing

答案D

解析 本题的空格处意为“要仔细权衡减肥药物的危险和好处”。weigh“仔细考虑某事物的相当价值或重要性,权衡,斟酌”,如:weigh the pros and cons(权衡正反两方面的意见)。value的意思是estimate the money value of something,即给某物估价,而 value sth./sb.是“重视某物或某人”的意思;evaluate“评估,估价”,evaluate sth.一般只是单独地评估某物,不含比较的意思;estimate(粗略)估计成本、大小、价值等。所以D项最恰当。
