Did you know heat, the transfer of thermal energy, moves in three main ways?

Conduction, convection, and radiation.

Conduction happens when heat travels through solids, like a spoon warming up in hot soup.

Radiation is heat moving through waves, like the warmth you feel from the sun. And convection.

That's when heat moves through liquids or gases, creating currents.

Let's take a closer look at convection.

In this first example, as the burner heats the liquid, the warmer, less dense liquid rises and the cooler,

denser liquid sinks, creating a continuous flow.

This is a convection current.

You'll see the same principle with this hot air balloon.

The burner heats the air inside, creating a convection current, heating the air and causing the balloon to lift.

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。
