【正确答案】 A

【答案解析】[解析] 文章第三段末尾指出：If it hears you coming，it will normally get out of the way as quickly as it can，but adders cannot move very rapidly and may attack before moving if you are very close．意思是：当蝮蛇听到人类走近它的时候，它会很快地让开路，但是由于它们不能爬得特别快，所以万一它觉得自己离对方很近的时候就会在爬走之前先发起进攻。所以答案选A，move out of your path意思相当于get out of the way。
