The Problems of Plastic Bags
塑料袋的问题
Plastic bags have found their way into a wide area of everyday life. They are provided in big supermarkets and corner stores. These bags do make people's life more convenient. They don't need to carry cloth bags, or baskets with them when going shopping. They are also very cheap so many people always buy them.
在日常生活的广大范围内都能找到塑料袋的踪影。大型超市和街角的商店都提供塑料袋。这些袋子确实使人们的生活更加方便。他们不需要随身携带布袋子或篮子去购物。塑料袋也很便宜，所以很多人经常买。
However, plastic bags also bring side effects. The plastic bags some people throw away casually cause the white pollution to our environment, which is very harmful because plastic bags cannot be decomposed.
然而，塑料袋也带来了副作用。有些人随手扔掉塑料袋对我们的环境造成了白色污染，这是非常有害的，因为塑料袋无法分解。
People have to be careful with the use of plastic bags. They should make sure they put the plastic bags into dustbins after the bags are used. It also might be better for people to use the traditional cloth bags to hold the goods instead of plastic bags.(137 words)
人们需要注意塑料袋的使用问题。他们应该确保他们扔进垃圾箱内的塑料袋是使用过的。对人们来说使用传统的布袋代替塑料袋来装东西也许会更好。

高分句型解析

英语四级作文高分句型解析：
The plastic bags some people throw away casually cause the white pollution to our environment, which is very harmful because plastic bags cannot be decomposed.
有些人随手扔掉塑料袋对我们的环境造成了白色污染，这是非常有害的，因为塑料袋无法分解。

点评：这是一个由which引导的非限制性定语从句，which指代的是前面整个主句，在主句中"some people throw away casually"是作定语修饰"the plastic bags"，在some前在略了that，在非限制性定语从句中又包含了一个由because引导的原因状语从句。
