There are many kinds of resources on the Earth.Four of them are very important.They are renewable,nonrenewable,human and capital resources.Renewable resources can be used again and again.They can be replaced within a short time.
Some energy resources are renewable.The energy from the sun,tides,water and wind is renewable.Also,trees and animals are renewable.But humans still need to take good care of them.We should not waste them at all.
Nonrenewable resources are limited in supply.Once we use them,they disappear forever.They can't be replaced.Many energy resources are like this.Coal,gas and oil are nonrenewable.
Human resources are people and the skills they have.This also includes the knowledge and information that humans have.People make products using renewable and nonrenewable resources.
Machines are often used to produce goods.The machines and tools that are used to produce goods are called capital resources.
地球上有很多種資源，其中有四種非常重要。它們是可再生的、不可再生的、人力和資本資源。可再生資源可以反覆利用。它們可以在短時間內被替換。
有些能源是可再生的。來自太陽、潮汐、水和風的能量是可再生的。此外，樹木和動物是可再生的。但人類仍然需要好好照顧它們。我們根本不應該浪費它們。
不可再生資源的供應是有限的。一旦我們使用了它們就永遠消失了。它們無法替代。許多能源資源就是這樣。煤、天然氣和石油是不可再生的。
人力資源是人和他們所擁有的技能。這也包括人類所擁有的知識和信息。人們使用可再生和不可再生資源製造產品。
機器通常用於生產商品。用於生產商品的機器和工具稱爲資本資源。
