问题 Safety goggles should be worn at all times______in testing areas.
选项 A、as
B、while
C、during
D、although
答案B
解析 空格后是in testing areas这样的介词词组，这样就排除了同为介词的(C)项during。这句话意在表达“在实验区域一定要带护目镜”，因此(B)项while是正确答案。这句话的完整表达是Safety goggles should be worn at all times while you are in testing areas，此处省略了“主语+动词”(you are)。像这样由when，while，though，wherever等引导的从句省略主语和谓语动词的情况非常多。
