每日一詞：開(kāi)綠燈

眾所周知，交通信號(hào)燈(traffic lights/ traffic signals)有“紅燈停，綠燈行(The green light allows traffic to proceed. The red signal prohibits any traffic from proceeding.)”之說(shuō)。

[SIPA]

“開(kāi)綠燈”指交通路口打開(kāi)準(zhǔn)許行人車輛通過(guò)的信號(hào)(give the go-ahead signal，give the green light)，后多用于比喻“允許某事(allow someone to do something or something to happen)”，或“提供方便條件(make easier for)”。

例句：

官僚主義總是為腐敗大開(kāi)綠燈。

Bureaucracy always gives the green light to corruption.

我們永遠(yuǎn)不會(huì)給賭博開(kāi)綠燈。

We'll never give the green light to gambling.
