 ♣ danger, hazard, peril, risk
　这组词都有“危险”的意思。danger是普通用语，含义很广，泛指任何可能发生的伤害或不良后果，适用于一切危险，如受害的遭遇、受害、受伤或丧命的可能性等；risk也属常用词，与danger相比，一般指难以预料的危险，常作“风险”解；hazard是正式用语，也指难以预料又无法控制的危险，但远不如danger和risk使用广泛；peril也属正式用语，常指严重而紧急的危险，多见于文学作品中。例如：
　High flood waters put the town in danger.　汹涌的河水使这个城市岌岌可危。
　In war a soldier's life is full of danger.　在战争中，士兵的生命是充满危险的。
