深入臺灣 |本集 精彩教學影片(講解老師:Bruce & Antony老師)
Learn all about these curious creatures and where to see them in Taiwan.
There is nothing like watching fireflies light up the sky on a warm evening. The sight of hundreds of fireflies twinkling in the night can create a magical memory. While the firefly’s ability to produce light may be fascinating, it isn’t actually magic.
People have wondered for a long time how fireflies can light up their bodies. Unlike most types of illumination, the light of a firefly isn’t hot. It is known as “cold light.” Scientists have studied these beautiful insects closely and now have a clear understanding of how they produce light. Fireflies create a special enzyme called luciferase, which they store in their abdomen with some other chemicals. When combined with oxygen, it creates a light that appears green, orange, or yellow.

Amazingly, fireflies can control this chemical reaction, similar to switching a flashlight on or off. They use tiny tubes on their body called tracheoles to collect oxygen. They control their flashes by opening or closing these tubes, which lead to the organ that emits light. Adult fireflies use their flashes to attract mates and communicate with each other. The lights also warn predators that they won’t taste very good.
Before making your decision, itʼs important to have a full understanding of the situation.
在你做決定之前,充分了解狀況是很重要的。
♦ in the night vs. at night
in the night 與 at night 在中文皆表「在夜晚」,但兩者意思有細微的不同,以下分別說明:
1. in the night
通常用來描述在夜晚的某個特定時刻發生了某事,等同於 during the night。
例: John kept waking up in the night.
約翰晚上一直醒來。
2. at night
at night 是更常見的用法,通常用來描述在晚上發生的事情,或者習慣性在晚上做的活動。
例: Itʼll turn cold at night.
晚上會變冷。
★ 補充用法
1. 介詞 in
可用於表年(in 2024)、月(in May)、上午/下午/晚上(in the morning / afternoon / evening)、季節(in spring / the spring)以及較長的一段時間(in the 19th century)。
2. 介詞 at
一般用來指幾點鐘(at nine o’clock)、確切的時間(at 9:30 a.m.)或某時刻(at dawn / noon / night),且不與定冠詞 the 並用。
請將下列字詞組合成一正確通順的句子
❶ A single match can ________________________.
a / up / dark room / light
❷ Before starting a new project, everyone needs to have ___________________________ the goals.

答案:
1. A single match can light up a dark room.

了解這些稀奇生物以及臺灣的賞螢好去處。
沒有什麼比得上在溫暖的夜晚觀看螢火蟲照亮天空。數百隻螢火蟲在夜空中閃爍的景象可以留下如夢似幻的回憶。雖然螢火蟲發光的能力或許令人著迷,但它並不是魔法。
長期以來,人們一直想知道螢火蟲是如何照亮牠們的身體。不同於大多數類型的光,螢火蟲的光並不熱。它被稱作「冷」。科學家仔細研究了這些美麗的昆蟲,現在對牠們如何發光有了清楚的了解。螢火蟲會產生一種稱為螢光素酶的特殊酵素,牠們會將其與其他化學物質一起儲存在腹部內。當該酵素與氧氣結合時,它會產生綠色、橘色或黃色的光。
令人驚訝的是,螢火蟲可以控制這個化學反應,類似於打開或關閉手電筒。牠們使用身體上稱為微氣管的細管來收集氧氣。牠們藉由打開或關閉這些細管來控制閃光,這些細管會通往用來發光的器官。成年螢火蟲利用閃光來吸引配偶並互相交流。這些光也警告掠食者牠們不太好吃。
