问题 The policemen went into action ______ they heard the alarm.

选项 A、promptly
B、quickly
C、presently
D、directly

答案 D

解析 directly和immediately和instantly意为“一……就……”,弓I导一个时间状语从句,如:In an insulating material,nearly all the electrons will return to their normal position directly the high voltage is removed.在绝缘材料中,高压一消失,几乎所有的电子就都返回原来的正常位置。
