我們大多數(shù)人都知道，人們?cè)诠?jié)日或游樂(lè)園里會(huì)放飛豐富多彩的氣球。但在飛機(jī)發(fā)明之前的19世紀(jì)，氣球在戰(zhàn)時(shí)被用來(lái)對(duì)敵人位置進(jìn)行偵探。
Most of us know balloons from festivals and fun fairs, where they are colorful and amusing, but in the 19th century, before airplanes were invented, balloons were used in wartimes to spy on the enemy position.
一到兩個(gè)人會(huì)帶著望遠(yuǎn)鏡進(jìn)入氣球，升到空中，而氣球則綁在地面的繩子上。

So before men would go up in a balloon, they would first float (or send up) a trial balloon without any men in it to test the situation.
如果敵人試圖攻擊這個(gè)試探性氣球，偵查人員就不會(huì)再坐上去了。
If the enemy tried to shoot that trial balloon, the men would not go up.
正是來(lái)源于此，在我們給某個(gè)項(xiàng)目投入金錢(qián)或精力之前對(duì)公眾的反應(yīng)或意見(jiàn)進(jìn)行試探的情況下，都可以使用這個(gè)成語(yǔ)。
From this origin, today we use this idiom in any situation where we want to measure public reaction or opinion before committing a lot of money and effort to some project.
