跟读练习: Eucalyptus Trees Are Built For Fire?! - 通过视频学习英语口语

1
Trees and fire don't usually mix well, so it's pretty strange that the eucalyptus tree is a pyromaniac.
2
Both its bark and leaves contain a natural kind of lighter fluid, and as they shed, they cover nearby plants and flammable kindling.
3
Any tiny spark can then cause the whole surrounding forest to go up in flames, and once the fire reaches the eucalyptus tree itself,
4
all that flammable fuel causes the tree to basically explode,
5
turning the scene into a five -alarm for the eucalyptus,
6
because eucalyptus seeds are basically fiber -proof.
7
Once all the surrounding plants have burned, there's tons of space for baby eucalyptus trees to repopulate the forest.
8
Many trees actually rely on fires to help them spread their seeds.
9
Most, like longleaf pines and giant sequoias, produce seeds that are sealed with resin.
10
When a fire comes along, it melts that resin and releases the seeds.
11
That way, all of the seeds germinate at the exact right time, when there's actually space cleared for new trees to grow.
12
But since those trees don't actually cause fires, their seeds sometimes have to lie dormant for decades until their lucky break.
13
The eucalyptus, on the other hand, makes its own fiery brand of luck.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
