俚语：go overboard
英文释义：to do something too much, or to be too excited and eager about something
本意为从船上掉到水中，就像一个粗心大意的水手，专心致意地忙着工作，一不小心，手没抓紧就掉下水去了。引申为鲁莽地采取行动。

例句：I wouldn't go overboard and buy a lot of stock in that company right now. I hear their profit is down from what it was last year.
我现在决不会太轻率地大量买那个公司的股票。我听说他们今年的利润比去年的低了。
