单选题 Please ______ yourself from smoking and spitting in public places, since the law forbids them.
  • A. restrain
  • B. hinder
  • C. restrict
  • D. prohibit
【正确答案】 A
【答案解析】[解析] 本题中restrain克制,抑制(不去做某事),与from搭配,可接反身代词;hinder妨碍,阻碍;restrict限制,强调少做某事,与to搭配;prohibit禁止,侧重外部因素如法律、规章制度等,常用被动语态。根据题意和结构,应选A。句意是:请不要在公共场所吸烟和吐痰,因为法律不允许。
