The policemen went into action ______ they heard the alarm.
A.promptly
B.quickly
C.presently
D.directly

参考答案

正确答案: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。
