Question

in an emergency和in emergency一样吗 emergency到底可不可数

Answer 1

两者的中文意思的确差不多,可理解为“在紧急的时候、在紧急情况下”.
in an emergency中的“emergency”属于名词,举例：It is important to keep calm in an emergency.（情况紧急的时候,保持镇静是重要的）；In an emergency phone 999 for help.（遇上紧急事件立刻拨999求救）.
in emergency中的“emergency”多属于形容词,举例：In emergency he assumes exceptional powers .（在紧急情况下,他还拥有特殊权力）；They were in emergency accommodation last night.（昨晚他们就住在紧急避险的住所）； I only drop it in emergencies.（我只在紧急时刻才会掉）.
emergency既是形容词,也是可数名词,举例（名词）：He deals with emergencies promptly.（他迅速处理突发事件）.
