正在创建课程...
1
The Grand Canyon, found in Arizona, USA, is a large and deep canyon that was created by the Colorado River over millions of years.
2
This amazing place shows us how water can change the landscape over time.
3
This canyon is really long, more than 445 kilometres, which is like driving from one end of the state to another.
4
It's also incredibly deep, about 1800 metres at its deepest.
5
That's so deep, it's like stacking 12 of the tallest skyscrapers on top of each other.
6
Plus, it's really wide, reaching up to 28 kilometers across at its widest points.
7
The Colorado River, still at the bottom of the Grand Canyon, continues to slowly wear away the rock.
8
The changes may be too slow for us to see day by day, but over millions of years, it's created this massive canyon.
9
The Grand Canyon is a fantastic example of this process in action.
10
Who knows, in another million years, the Grand Canyon might be even wider and deeper than it is today.

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。
