Threshold

香港5月1日起放寬非香港居民的入境限制,而且會同步調整放寬航班的熔斷機制,確診乘客的門檻(threshold)將由3人提高到5人。

名詞threshold用作描述程度時,解「門檻、界限、起點」,即是某事情開始發生或者開始體驗到某事情的水平。例如,Young children normally have a very low boredom threshold.(幼兒通常容易感到無聊乏味。)

The government should lower the threshold for applying for the Elderly Dental.(政府應降低申請長者牙科服務的門檻。)

名詞threshold除了配搭動詞have和lower,可以配搭raise(提高)、exceed(超過)、cross(超越)等等。例句︰We have achieved and exceeded the threshold for herd immunity of 75 percent.(我們已經達到並超過了75%的群體免疫門檻。)

Hong Kong crossed the threshold of one million cases of Covid-19.(香港突破了100萬確診個案的界綫。)

至於形容詞,threshold大多配搭low或者high。例如︰These soldiers are trained to have a high pain threshold.(這些軍人被訓練到很能忍受痛楚。)

The government tends to maintain a low tax threshold.(政府傾向於維持較低的稅收起徵點。)
