跟读练习: What Is The Rain Shadow Effect? Here's A Simple Explanation! - 通过视频学习英语口语
正在创建课程...
1
This is the Rocky Mountains, a mountain range in North America stretching from western Canada to New Mexico.
2
Now, look closely.
3
Some parts of it are green, but right here, there's a desert.
4
Why?
5
Well, this is called the rain shadow, and it's a common occurrence in the mountains.
6
It forms on the side of a mountain that is opposite to the wind.
7
So here's how it works.
8
The wind that approaches the mountain brings along some moisture from the sea or the ocean.
9
As the air goes up the mountain, it expands and cools, dropping rain and snow along the way.
10
So that side is well-moisturized with greenery, maybe even flowers somewhere along the way.
11
As the air passes the peak and goes back down, it warms up and the clouds dissipate.
12
So there's almost no moisture left anymore and that side of the mountain stays dry.

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。
