答案:
B解析试题分析:考查固定词组,make difference意思“有不同”,make different意思“将某物与某物区分”,makes a difference意思“有影响”,句子意思“万一有紧急情况,是否知道怎样提供急救对于关系像红肿手腕、骨折、烧伤、刀口等创伤有很大影响”,所以选B考点:考查固定词组点评:注意固定句型In case of意思“万一”,句子 whether knowing how to apply first aid or not really…,是whether引导的主语从句,主语从句中又含有how引导的宾语从句。动名词concerning做名词matters后置定语。
