As we know,waste sorting is the process in which garbage is separated into different elements, including recyclable,poisonous and harmful garbage, kitchen waste and so on. By sorting the recoverable garbage, we are able to reduce the use of raw material, which greatly relieves the pressure of resource shortage.As for poisonous and harmful garbage, only when it is collected together and processed in a special way can we reduce the pollution from it. And for sorting out otherwaste, it is also beneficial to our life. Nowadays,our government attaches great importance to waste sorting, and even in some cities it has issued some laws and regulationsto motivate public participation in it. All in all, it is everybody’s duty to sort out waste well.（二）人们每天都会产生大量垃圾，如何解决这个问题？可以采取垃圾分类的方法。要点如下：1.垃圾的来源；2.垃圾分类是一种很好的处理方法；3.垃圾分类的好处；4.如何分类。【参考范文】 Society produces a lot of rubbish, such as leftover food, waste paper, plastic bottles and batteries every day.

Waste sorting can help divide the reusable waste from the rest. And there are two reasons for doing this.Firstly,the earth is limited in its natural resources,and many products are made from finite resources, whichcannot be generated by nature in a short period of time. Simply dumping this kind of products is wasting resources. Secondly, some part of the waste is of value. To reuse and recycle this kind of waste is to save resources to a large extent, which also contributes to environmental protection. Sorting waste is a meaningful deed. If everyone can do it, small things can make a big positive impact on the environment.（四）地球的资源是有限的。我们应该珍惜并珍惜这些资源。具体到个人，如何去做呢？要点如下：1.将垃圾进行分类，然后再次使用可用的资源；2.提醒家里的每个人对垃圾进行分类（举例子说明）；3.在学校里，将垃圾分为可回收和不可回收并和同学讨论分类的办法；4.在郊区，对看到的垃圾并进行分类；5.垃圾分类的好处。【参考范文】 The resources of the earth are limited.
