stangers什么意思

发挥经常发生在不是戏剧的动物。The girl was shy in the presence of stangers.这个女孩在陌生人面前显得腼腆。He was calm in the presence of danger.危险面前他镇定自若。He was clam in the presence of danger.在危险当中他镇定自若。Speak out in the presence of everyone.当着大家谈。
回答：C while在此处当连词使用，可以有两种结构：whille+从句；while+doing sth A项with前面应该有个动词，排除；B项walk for,for很明显是为了……的意思，不合题意；C项train意思是训练，符合题意get的用法：表示让……做……get sb/sth do;get it run让他乱跑，句中表示不要让狗乱跑，所以正确还有呢？
