1
Are you familiar with the word symbiosis?
2
It's a fancy term for a partnership between two different species, such as bees and flowers.
3
In a symbiosis, both species depend on each other.
4
I want to tell you about a remarkable symbiosis between a little bird, the Clark's nutcracker, and a big tree, the whitebark pine.
5
Whitebark grow in the mountains of Wyoming, Montana and other western states.
6
They have huge canopies and lots of needles, which provide cover and shelter for other plants and animals, and whitebark feed the forest.
7
Their cones are packed with protein.
8
Squirrels gnaw the cones from the upper branches so they fall to the ground, and then race down to bury them in piles, or middens.
9
But they don't get to keep all of them; grizzlies and black bears love finding middens.
10
But there's more to a symbiosis than one species feeding another.
11
In the case of the Clark's nutcracker, this bird gives back.
12
While gathering its seeds, it also replants the trees.
13
Here's how it works: using her powerful beak, the nutcracker picks apart a cone in a treetop, pulling out the seeds.
14
She can store up to 80 of them in a pouch in her throat.
15
Then she flies through the forest looking for a place to cache the seeds an inch under the soil in piles of up to eight seeds.
16
Nutcrackers can gather up to 90,000 seeds in the autumn, which they return for in the winter and spring.
17
And these birds are smart.
18
They remember where all those seeds are.
19
They even use landmarks on the landscape -- trees, stumps, rocks -- to triangulate to caches buried deep under the snow.
20
What they don't go back and get, those seeds become whitebark.
21
This symbiosis is so important to both species that they've changed, or evolved, to suit each other.
22
Nutcrackers have developed long, tough beaks for extracting seeds from cones, and whitebarks' branches all sweep upwards with the cones at the very ends, so they can offer them to the nutcrackers as they fly by.
23
That's a symbiosis: Two species cooperating to help each other for the benefit of all.

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。
