tipster

1.We couldn't hear the starting announcement above the hubbub of bettors, speculators, tipsters, and touts.

在打赌者、投机者、密者及出售赛马者们的喧嚣声中我们无法听到开始的宣告。

2.The occasional anonymous tipster and the eminent autobiographer may each claim to be serving the cause of truth.

停滞不前的村落社会和完 全 没有活力的农业；

3.One tipster told the tech blog Boing Boing that he was “told by a friend” that slaughterhouses in Iraq sometimes dump blood in canals.

一位知，一位朋友告诉他，伊拉克的屠宰场把血倒入这个湖里。
