每十年減輕2%
A recent study published in Science Advances points out that birds in the Amazon rainforest have gotten smaller over the last four decades, and scientists believe that rising temperatures may be the reason.
近期發表在《科學先端》的研究指出亞馬遜雨林的鳥類在過去四十年間體型變小了，而科學家相信氣溫上升是可能的原因。
study (n.)研究,調查point out 指出
The research team has analyzed the sizes and weights of 77 different bird species since the early 1980s.
研究團隊從1980年代早期開始分析77種鳥類的體型和體重。
species (n.)物種
They discovered that as time goes on, nearly all the bird species have gotten lighter, with most species becoming about 2% lighter every decade.
他們發現隨著時間的進展，幾乎所有的鳥都變輕了，而且大部分的鳥類每十年就會減輕2%。
with+受詞+現在分詞V-ing 表示附加狀態light (adj.)很輕的
For such small creatures, 2% weight loss is significant. Moreover, not only have the birds’ bodies shrunk over time, their wings have gotten longer.
對如此小型的生物來說，2%的體重流失是很多的。此外，不只有體型隨著時間縮小，牠們的翅膀也變長了。
loss (n.)失去；lose (v.)失去over time 隨著時間的推移,漸漸地= with time, graduallyovertime (n.)(adv.)加班,運動比賽的延長賽
The researchers believe this to be an adaptation to warmer temperatures since longer wings and smaller bodies allow birds to use less energy to move around and stay cool.
研究人員相信這是為了要適應更加溫暖的氣候，因為較長的翅膀和較小的體型可以讓鳥類用較少的體力移動並保持涼快。
adaptation (n.)適應,改編
Vitek Jirinec, ecologist and lead researcher of the study, worries that the phenomena may not be limited to the amazon rainforest.
生態學家、也是該研究的首席研究員維塔克．伊里內克擔心這種現象不侷限於亞馬遜雨林。
ecologist (n.)生態學家；ecology (n.)生態學lead (adj.)領導的,最重要的phenomenon (n.)現象be limited to侷限於
Birds all over the planet may experience changing shape due to global warming.
地球上的鳥類都可能因為全球暖化而經歷體型轉變。
due to因為=because of, owing to
Perhaps it is high time that humans considered the consequences of our actions and if it is worthwhile to sacrifice the environment for economic growth.
也許人類是時候該審視我們行為所造成的後果，並考慮是否值得為了經濟成長而犧牲環境。
it is high time that S+V-ed 是時候該……consequence (n.) 後果worthwhile (adj.) 值得的
