隔音室錄音實驗
Although they cannot be heard within the range of human hearing, scientists have discovered distress calls emitted from plants for the first time.
儘管植物發出的痛苦求救聲無法被人類所聽見，但科學家首次發現了這個現象。
range (n.)範圍distress call 求救訊號、危難訊號=distress signal
Recent research published in Cell has revealed that plants will “emit popping and clicking noises in ultrasonic frequencies” under certain conditions to express their pain to other living beings around them.
最近在《細胞》期刊上發表的研究顯示，在特定的情況下，植物會「以超音波頻率發出劈啪和咔嗒聲」，向周圍的其他生物表達它們的痛苦。
reveal (v.)揭露、透漏ultrasound (n.)超音波ultrasonic (adj.)超音波的
Despite seeming passive, many plants actually have noticeable active responses to changing conditions around them.
儘管看似被動，但許多植物實際上對周圍環境的變化有明顯的主動反應。
passive (adj.)被動的active (adj.)積極的、主動的noticeable (adj.)明顯的、容易注意到的
While some of these behaviors, such as releasing aromas or changing colors and shapes, have previously been studied, this new research into plants` production of sound has made some startling discoveries.
雖然其中一些行為之前已經被研究過，例如釋放氣味或改變顏色和形狀，但植物發出聲音的新研究卻帶來了一些驚人的發現。
while (conj.)雖然、儘管aroma (n.)氣味、香氣startling (adj.)令人震驚的
According to Lilach Hadany, an evolutionary biologist at Tel Aviv University in Israel, the new research stemmed from findings that plants could detect sounds around them.
以色列特拉維夫大學的演化生物學家哈丹尼指出，這項新的研究是來自植物可以感知周圍聲音的發現。
evolution (n.)演化、進化、發展evolutionary (adj.)演化的revolutionary (adj.)革命性的、非常創新的stem from 源自、由……造成
Researchers recorded sounds in both soundproofed spaces and normal greenhouse environments with special equipment to test if plants could respond similarly.
為了測試植物是否能有類似的反應，研究人員使用特殊的設備在隔音室和一般溫室環境下進行錄音。
-proof (suffix)防……的
After getting a baseline recording of unstressed tobacco and tomato plants, they also recorded the sounds produced by cut plants and dehydrated plants.
在錄下未受壓力的煙草和番茄的基準音檔後，他們還錄製了斷莖植物和脫水植物產生的聲音。
baseline (n.)基準、基線dehydrated (adj.)脫水的
With the help of machine learning algorithms, these sounds were evaluated and categorized.
藉由機器學習演算法的協助，對這些聲音進行評估和分類。
algorithm (n.)演算法evaluate (v.)評估category (n.)類別、種類categorize (v.)分類
The main finding was that distressed plants emitted popping and clicking noises at around 40 clicks per hour depending on the species.
研究主要發現是處於痛苦狀態的植物會發出每小時約40次的劈啪和咔嗒聲，視植物種類而異。
depend on 取決於……
Additionally, dehydrated plants behaved similarly with their numbers and patterns of sounds.
此外，脫水植物的出聲的次數和模式類似。
behave (v.) （在某種環境或條件下）做出特定行為
In fact, such noises have been observed in many other species of plants, including wheat, corn and cactus.
事實上，這種聲音在許多其他種類的植物中也被觀察到，包括小麥、玉米和仙人掌等。
observe (v.)觀察botanist (n.)植物學家
Despite these amazing discoveries, the origins of the sounds are not yet known, setting the stage for further scientific inquiry into the mysteries of plants.
儘管有這些驚人的發現，但還無法確定聲音的來源，植物的奧秘尚有更進一步的科學研究空間。
