Unit 2.

B. The 1 ,000 -year birdsong A.
3
Every summer the calls of thousands of swamp sparrows can be heard across North America's wetlands.
4
These little brown birds know only a few songs but they know them very well.
5
In fact, Their musical set list probably hasn't changed much for centuries,
6
Be like humans, baby swamp sparrows learn to communicate by copying adults.
7
From a young age, they learned to copy or mimic Songs sung by their elders.
8
Swamp sparrows very rarely make mistakes when they learn their songs, says biologist Robert Lachlan.
9
In fact, their mimicry is so accurate that the music changes little between generations.
10
See, just like children, The sparrows don't remember every song they hear, Lachlan says, They don't just learn songs at random,
11
they pick up commoner songs rather than rarer songs.
12
In other words, they learn songs they hear most often.
13
It's an example of a strategy that scientists call conformist bias.
14
Until recently, this learning ability was thought to be special only to humans.
15
D. Between 2008 and 2009, Lachlan's research team recorded the calls of 615 male swamp sparrows across the northeastern United States.
16
The researchers used computer software to break each song into a collection of notes or syllables
17
They then measured the differences between the tunes,
18
e The research revealed that only 2 % of male sparrows sung a different song from the standard tune.
19
The combination of accurate mimicry and conformist bias allows the birds to create traditions that last for centuries.
20
With those two ingredients together, you end up with traditions that are really stable, says Lachlan.
21
The song types that you hear in the marshes of North America today may well have been there 1000 years ago.
22
F. Lachlan's study is among the first to measure the longevity of song traditions within a bird species.
23
Another aspect scientists are now exploring is the impact of habitat loss on songbirds.
24
Man -made barriers, such as cities, roads and plantations, can break up a bird population into a number of isolated groups.
25
These barriers may prevent cultural interaction between songbird populations such as the exchange of song types,
26
G The findings are really exciting, says scientist Andrew Farnsworth.
27
He hopes that future research will evolve from these studies.
28
For example, scientists may be able to identify how other animals are able to preserve their cultural traditions.
29
Seeing the potential for it in other organisms is super cool, says Farnsworth.

上下文與背景
在這段影片中,講述者介紹了北美溼地的沼澤麻雀及其獨特的鳥鳴。這些小巧的棕色鳥類以其只有幾種歌曲而著稱,它們通過模仿成年鳥學習如何發聲。研究員羅伯特·拉赫蘭的研究顯示,這種模仿能力和他們的文化傳承不僅在鳥類界獨特,甚至曾被認為是人類的專利,這使得這些鳥類的歌曲在多個世代之間幾乎沒有任何變化。這一現象展示了動物學習的複雜性,以及自然環境對其文化保留的影響。

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。
