1
Soil is an interesting mix.
2
It contains tiny rock pieces, air, water and something special, known as humus.
3
Humus is a bit like compost.
4
It comes from the remains of dead plants and animals,
5
enriching the soil with nutrients needed by plants and tiny creatures living in the soil.
6
But soil is not all the same.
7
It has three main types of tiny rock particles.
8
Sand, silt and clay.
9
The amount of sand, silt and clay in soil determines how much air and water the soil can hold.
10
Let's talk about sand first.
11
These are the largest particles.
12
If soil has a lot of sand, water goes right through it like it's rushing through a sieve.
13
Silt particles are smaller than sand but bigger than clay.
14
In soil with lots of silt there is less space for air and it holds more water than sandy soil.
15
Think of it like a sponge that soaks up and keeps water better than a sieve.
16
Clay particles are the smallest of all.
17
In soil with lots of clay, the tiny particles pack closely together leaving little space for air.
18
Water also drains slowly through clay-heavy soil, much like how water struggles to pass through thick dough.

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。
