每日一词学英语(15): once bitten, twice shy

这个和“一朝被蛇咬，十年怕井绳”对应。例子如下：

This has resulted in a feeling of "once bitten, twice shy" among certain investors, while the lack of a dividends from three major banks has been a further reason to avoid the shares.
一些投资者由此产生“一朝被蛇咬，十年怕井绳”的心理，缺少红利更让这些人不敢碰这三家银行的股票。

类似的说法还有：the burnt child dreads the fire；the scalded dog/cat fears cold water等，例子暂时没见到。
