问题 They had to wait fifteen minutes for the anesthetic to______before they stitched up the cut.
选项 A、take turns
B、take charge
C、take offence
D、take effect
答案D
解析 动词词组辨析。take effect表示“(药物)见效，奏效”，如：The medicine quickly took effect and I felt a little sleepy．这种药很快就见效了，我感到有些困意。此词组还可指“(法律)生效，实行”，如：The new system will take effectnext January．新的制度将自明年一月起实施。此外，come／go into effect同样表示“(法律等)开始实施，生效”，如：The government censorship went into effectlast week．上周政府审查制度开始实施。
