选项
A、so that
B、providing that
C、in case
D、if
答案
A
解析
本句中前一分句与后一分句构成原因与结果的关系,故选so that。in case,以防;in case 若用于现在时或将来时中,时态正常处理;但若用在过去式中, in case 后面通常接should 引导的虚拟语气。例:I packed a swimsuit in case I should have time to go to the beach.我把泳衣包起来了,说不定有时间会去海滩。in case of 等于if,后接名词,如:In case of fire,break glass.如果失火了,就要马上打破窗户玻璃。in any case 在任何情况下,in most cases在大多时候,这些case 词组用法都很广泛。providing that,providing,provided that,provided意义相同,同等于if
