When you turn on the television,put on your shoes or drive to a store,you’re using energy. Energy is one of the most fundamental forces in the world. Animals use energy to walk and run. Trees and plants use energy to grow. People use it to work and play. Energy is everywhere in nature-in the light of the sun,in the wind,in the forest,in water currents and erupting volcanoes. Without energy,there is no life. We use our own energy constantly and we continually make use of all kinds of energy.
Energy can be divided into two different types:stored energy and dynamic energy. Stored energy is caned potential energy,and the latter refers to energy in motion. If you stretch out a rubber band,this produces potential energy. If you let it go,it moves and produces the dynamic energy.

答案
当你打开电视、穿鞋子、或驾车购物,你都在消耗能量。能量是世界上一种最基本的力。动物行走、奔跑,树木、植物生长,人类工作和消遣,都在消耗能量。能量存在于阳光、风、树林、水流和喷发的火山中,自然界中无处不在。没有能量,就没有生命。我们在不断地消耗自身的能量,也在不断地消耗其他种类的能量。能量有两种不同的类型:储能和动能。储能被称之为潜能,而动能被称之为运动能。如果你把橡皮筋拉长,这就产生了潜能;你一松手,它就会收缩并产生动能。
