1
An eagle flies high in the sky.
2
It uses its keen sense of sight to search for fish in the lake below.
3
When it spots a fish, it dives down and catches it in its sharp talons.
4
All organisms respond to stimuli.
5
A stimulus is a change of signal in an organism's environment that the organism can recognize and react to.
6
In the case of the eagle, the stimulus was spotting the fish in the water.
7
The reaction to that stimulus is called a response.
8
The eagle's response to seeing the fish was to swoop down and catch it.
9
Responses help an organism survive and adapt to its environment.
10
Plants for instance have unique ways of responding to stimuli.
11
Many plants react to light, a process known as phototropism.
12
plants turn their heads to follow the sun across the sky, soaking up as much sunlight as possible for photosynthesis.
13
Another type of response in plants is towards gravity, a process known as geotropism.
14
This response guides roots to grow downwards into the soil, and stems upwards towards the sky.
15
An interesting example of plant response to stimulus is the Venus flytrap.
16
This carnivorous plant closes its leaves when an insect lands on them, capturing its prey for digestion.
17
Animals also exhibit a wide array of response to stimuli.
18
For instance, a rabbit, upon sensing a predator, instinctively runs to escape, demonstrating a basic survival mechanism.
19
Similarly, when a gazelle senses a change in the wind direction carrying the scent of a predator, it quickly alters its cause to avoid detection.
20
Birds too respond to seasonal changes.
21
As winter approaches, many species migrate to warmer regions, ensuring their survival during harsh weather conditions.
22
Even a simple organism like an earthworm reacts to light by moving away from it, preferring to stay hidden in the dark soil.
23
Even the simplest organisms such as single-celled amoeba or paramecia have the ability to respond to stimuli.
24
For example, if these microorganisms encounter a harmful substance, they will move away from it.
25
But if they detect a food source, they will move towards it.
26
These examples demonstrate that the capacity to respond to stimuli is an essential characteristic of all organisms,
27
helping them interact with their environment, adapt to changes and ensure their survival.

本節課學習內容
通過本節課,你將練習如何用英語描述生物對刺激的反應,同時提升英語口語表達能力。影片中涵蓋了鷹、植物、兔子等多種生物的例子,語言生動且邏輯清晰,非常適合用於“看影片學英語”和“英語口語練習”。你不僅能學習到相關科學知識,還能通過模仿語音語調來強化口語技能。
核心詞彙與短語
- stimulus:刺激(生物體環境中的變化或訊號)
- response:反應(生物體對刺激的回應)
- phototropism:向光性(植物對光線的反應)
- geotropism:向地性(植物對重力的反應)
- migrate:遷徙(鳥類等隨季節變化移動)
練習技巧
影片的語速適中,語調平穩,非常適合“英語影子跟讀”(shadow speak)練習。以下是具體建議:
- 先完整觀看影片,理解內容後再開始跟讀。這樣能幫助你專注於語音模仿,而非內容理解。影片中對生物反應的描述邏輯嚴謹,跟讀時要注意句子的停頓和重音,比如在“the stimulus was spotting the fish”中,重音應放在“stimulus”和“fish”上,突出因果關係。
- 逐句跟讀,每句重複3-5次。影片中包含不少長句,如“Plants turn their heads to follow the sun across the sky, soaking up as much sunlight as possible for photosynthesis”,跟讀時要注意分句之間的連讀和語調變化,保持語氣的自然流暢。
- 模仿影片中的語氣。講解科學知識時,語氣應冷靜且富有條理,你可以通過調整語速和音量來體現這種風格。比如在描述“Venus flytrap closes its leaves”時,適當放慢語速,突出“closes”的動作感,增強表達的生動性。
堅持使用這些技巧練習,能有效提升你的口語流暢度和語音準確性,讓你在“shadowspeaks”練習中取得更好的效果。
什麼是跟讀法?
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧,最初開發用於專業口譯員的培訓,並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大:您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同,跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性,語調,節奏,連讀,聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
