1.一次性塑料袋曾被广泛的使用
2.造成的问题
3.限制使用的意义
Disposable plastic bags were once widely used in China. When we went shopping at supermarkets and departments stores, shopping assistants often provided free plastic bags for our convenience. For a while, life without them seemed unimaginable for most of us.
However, disposable plastic bags do bring severe damage to our environment. Costumers usually threw them away after use, and because they are thin and hard to decompose, these plastic products will exist for a long time. This is an immediate threat to our earth and water.
Nowadays, the government has passed relevant regulations for limiting the use of disposable plastic bags: they are not free any more. In some shopping places, in order to invoke the public awareness of environmental protection, plastic bags are offered in a much higher price. As a result, people are changing their behavior: paper and clothing bags that vanished for a long time come back to our daily life. It is true that by limiting its usage, everyone in this society contributes some effort to the improvement of the environment.

· Limiting the Use of Disposal Bags
·These days disposal products often hit the headlines of newspapers and have been brought into focus of the public. Indeed, it is widely accepted that they have gained increasing popularity among people in all walks of life. Taking a look around you, you can find examples too numerous to list: When you walk on the street, you can see plastic bags flying over your head; When you ramble along the river, you can find plastic bottles floating on the water; When you stroll in the park with your lover, you can notice waste paper thrown everywhere.
· Among the most important reasons often cited by people is the quickening pace of modern life. They are often too busy to wash dirty dishes or glasses, as a result they can do nothing but use disposal products. Also playing a part is the improvement of people's life. As a result of the policy of opening and reform, an increasing number of people are much richer than before and can afford disposal products. (原因)
· Admittedly, they might benefit us in a short term. Unfortunately, they will do us harm in more than one way. The major harm is (that) they are sure to pollute the environment. To make matters worse, they are likely to have potential harm to public health. To illustrate this point, I can think of no better example than HP, the river through S. As a result of disposal products in it, the water has caused some diseases in the local people. (影响)
· To sum up, for the factors mentioned before, we can safely reach the conclusion that the prevalence of disposale products is bound to cause a chain of undesirable effects. In view of the present situation, it is high time that the government tried every means to protect the environment. Only in this way, can we have a bright future.

Plastic bags have been an indispensable part of our daily life for it brings us much convenience. We are so dependent upon plastic bags that use of them is ever increasing.

1. 一次性塑料袋的使用
2. 使用一次性塑料袋带来的问题
3. 限制使用一次性塑料袋的意义
For many years we have been using disposal plastic bags when we are shopping on the market, and most often these bags are offered by the shops for free. This, undoubtedly, has brought us great convenience in our daily life.
However, its disadvantages are also very apparent, and I’ll just venture to explore two aspects. For one thing, the plastic bags are mostly indecomposable in the natural state so that with the increasing use of these bags, it will not only seriously bring about the so-called “white pollution” to the environment, it can also cost us a lot to have them decompose completely so as to minimize their damage to the environment. For another, the production of plastic bags are often not strictly supervised, so a large proportion of the bags don’t meet the requirements for healthy products, which means the more we use them, the more likely we are to suffer in health.
The negative effects of the plastic bags are far serious than what I’ve mentioned above, so it’s high time the government issued strict laws and measures to stop using the bags. By so doing, we can save a lot of money from producing these bags as well as return a cleaner earth to ourselves and the later generations.

论文四级标题格式范例

　　论文的第四级标题该怎么弄？其的'格式是怎么样的？下面我为你带来论文四级标题格式范例，希望能对你有所帮助！

　　1、论文目录的标题层级只做到第三级，不需要第4级标题。

　　2、第4级标题只在正文中使用，一般有两种表达方法：

　　第一种：

　　（1）

　　（2）

　　（3）

　　注意：

　　1）括号之前要空两字距（如同：文内自然段的起首），括号之后不加标点；

　　2）括号内的阿拉伯数字使用新罗马体（Times New Roman）；

　　3）第4级标题的字号与正文字号相同，即小4号，字体为宋体，不加粗；

　　4）第4级标题一般占一行，结尾处不用加句号或其他任何标点。

　　第二种：

　　第一，或首先，其一，

　　第二，或其次，其二，

　　第三，或第三，最后，其三，

　　注意：

　　第一或第二或第三之前要空两字距（如同：文内自然段的起首），之后加标点“，”然后接相关文字内容。

　　3、第4级标题两种表达形式的选择取决于其下内容的多少：当内容多、层次丰富时，采用第一种形式；当内容少、涉及层次简单时，采用第二种形式即可。

　　4、什么情况下使用第5级标题层次？当第4级标题之下、内容多、层次丰富时，可使用第5级标题层次，如使用①、②、③；或第一、第二、第三等。操作时，可视具体情况灵活处理，但要求全文要一致。

　　5、特别注意：根据行文的实际情况，不需要使用第4级、特别是第5级层次的标题时，尽量不要使用。否则，标题层级太多反而破坏了论文的自然流畅性。
