The doctor came out and said the operation was well finished. The parents smiled ________ and the nervousness disappeared from their faces.A.in reliefB.in dangerC.in peaceD.in reality

A解析试题分析：A. in relief如释重负般地 B. in danger处于危险中 C. in peace和平地D. in reality事实上；句意：医生出来了说手术非常的成功。父母亲如释重负般的微笑了一下，那种紧张感也烟消云散了。故选A考点：in +抽象名词点评：“in +抽象名词”是英语中用途非常广泛的表达，完全可以用于作文中，表示主语所处的某一种状态，而“of +抽象名词”相当于这个抽象名词同根的形容词形式，如of great use =useful这个短语也是非常常用的，学生要牢记。
