4
energy makes things move it powers the machines we use it can make things get hotter
5
or produce sound energy is used to light up our homes
6
and cities and power the vehicles we use all organisms need energy to grow reproduce and carry out life processes.
7
Plants use the light energy from the sun to make food in the form of sugar.
8
This energy is passed to animals when they feed on plants and other animals.
9
There are two main forms of energy, kinetic energy and potential energy.
10
Kinetic energy is the energy of movement.
11
Mechanical energy, sound, light, heat and electrical energy are all examples of kinetic energy.
12
You can learn more about these forms of kinetic energy in our related videos.
13
energy is the energy something has due to its position, composition or state.
14
The stored energy can be converted into various types of kinetic energy.
15
Fuels such as petroleum, gas and wood contain a form of potential energy called chemical energy.
16
When these fuels are burned, the chemical energy is converted into light and heat.
17
Potential energy due to an object's position above the ground is called gravitational potential energy.
18
A rock on top of a hill has gravitational potential energy.
19
As it rolls down the hill, the potential energy is converted into kinetic as it is pulled down by the earth's gravity.
20
An arrow in a bow has potential energy due to its position behind the drawn string.
21
This is called Elastic Potential Energy.
22
The elastic potential energy increases the more the string is drawn back.
23
When the string is released, the potential energy is converted into kinetic energy as the arrow flies forward.
24
That's pretty cool.
25

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
