在我们班，男生门天天议论着网络游戏攻略，女生们则谈论着昨天与某某网友聊QQ发生的事，有的人说，中学生可以上网，有些人则说不能，依我个人而言，这两种说法都太片面。其实中学生可以适当上网。因为在网络上我们可以找到学习的资料，也可以跟网友交流一下学习经验。现在网络资源丰富，还有很多的网校辅导课堂，这样可以得到自己需要的东西，对我们的学习很有帮助。既然如此，中学生就可以上网。当然，上网主要以学为主，也可以适当玩一些游戏，听听歌什么的放松自己。
首先，上网聊天需要花费我们大量的时间。而现在我们这个年龄是一个人人生当中学习的最佳阶段，我们应当把握好这个时机，把思想放在学习上，不断用知识充实自己的大脑，提高自己的`能力，才能在日趋激烈的社会竞争中处于不败之地。如果整日沉迷于网吧，学习走下坡路，我们怎么能在社会上立足呢？一个连“立足”都不能的人，又有什么资格去谈为祖国做贡献呢！其次，我们青少年还不具备足够判断是非曲直的能力，往往会受不良影响，误入歧途，造成一生都难以挽回的遗憾。虽然网上生活给人一种全新的感觉，这种感觉很具有诱惑力，但这毕竟是虚拟的，因为在网上了解一个陌生人，只不过是通过和他谈话，却无法去深入了解他的内心他的品德。近几年来，因网络等发生危害少年身心健康的事不在少数。
我认为中学生上网是可以的，但必须得有个前提，以学为主，随着科技的发展，中学生上网会非常普遍，如果上网是为了学习，摘取资料，那么上网就并非坏事！

Nowadays, many famous university campuses have become one of the popular tourist attractions. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. In the place far away from the capital city, the local students also visit the universities famous in their own province.
So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions. On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere.
In my opinion, the tourism to the universities is not a good thing. The campus is mainly a place for study. With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.
首先，提纯范文 “谋篇布局”及结构模板。
第一段：提出问题或现象。Nowadays, … … have become one of the popular … …. It has been shown on TV and on the radio that … ….
第二段：正反列举人们的看法。So far as the present situation is concerned, is it a good or bad thing to … …? Different people have different opinions. On one hand, some people argued that it is a good thing for … … in that … …. On the other hand, some people hold a negative view about this phenomenon. In their opinion, … … will have negative effect on … … because it will not only do harm to … … but also to … ….
第三段：摆明自己观点。In my opinion, … … is not a good thing. … … With the increasing … …, it will ruin … ….
其次，提纯范文“段落写作”。
段落写作分为统一性，连贯性和完整性三方面。
统一性(unity：段落开头的主题句应该做到不可太宽泛，也不可太具体，做到有较强的概括性才能使下文做到有的放矢的展开。范文第二段首句以设问的方式提出一个问题is it a good or bad thing就有很强的概况性。下文自然会一方面从好的方面说明，另一方面从坏的方面说明。
连贯性(coherence：关联词是使文章段落之间相互连贯的必要条件。范文中nowadays, on one hand, on the other hand, in one’s opinion即以“启承转合”递进的顺序是文章条理清晰，层层展开。
完整性(completeness：以设问句“So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists?”开头，这是平时较少运用的段落写作方式——设问法。“On one hand … …. On the other hand, … ….”是段落写作分类列举法的典型用法。
再次，提纯范文“句子写作”。
1. It has been shown that … …
类似句型：It is known to us that … …
It is said that … …
It is reported that … …
It is controversial that … …
2. “… … Tsing Hua University and Peking University and other famous universities … …。”——并列句。并列句是简单的复杂句。但其运用方法并不简单，注意练习并接句的使用，会使句子显的更加饱满。
3. enable v. 使…能够
I gave him full directions to enable him to find the house.
4. in that = because
表“因为”的连词还有since, for, as，如：
The boy was absent because he was ill. = The boy was absent since he was ill.
此句以我们常用的人称开头，句式简单，我们可以通过把since提前改变句式，如：
Since the boy was ill, he was absent. 句式多样化。
最后，提纯范文“措辞”。
1. attraction n. 具有吸引力的事情。
2. thousands and thousands 成千上万的
形容“多”的表达方法：millions and millions
a multitude of
a great deal of
a large amount of
plenty of
many a
3. “some people argued that … …”中的“argue”并不是“讨论，辩论”的意思，而是“认为”。
I argue that … …
I maintain that … …
I claim that … …
I insist that … … = I think that … …
I hold that … …
I assert that … …
I assume that … …
4. negative adj. 否定的.，相反的
hold negative view = hold opposite opinions
5. phenomenon n. 现象
social phenomenon 社会现象
natural phenomenon 自然现象
6. intellectual adj. 聪明的= intelligent, bright, clever
(选词策略：使用最近所学的单词，如intellectual > intelligent > bright > clever
在分析并掌握范文之后，我们需要运用范文知识练习仿写。笔者运用2005年12月范文中的模板结构仿写了2006年12月的四级作文，以供参考：
1. 许多人喜欢在除夕夜看春节晚会
2. 但有些人提出取消春节晚会
3. 我的看法
Nowadays, the Spring Festival Evening has become one of the popular topic and attractions during every traditional New Year’s Eve. It has been shown on TV and on the radio that every year thousands and thousands of Chinese people appear to be accustomed to enjoying the sights and sounds of a brilliant feast, while gathering with their beloved family.
However, an increasing number of people have voiced different opinions towards it. So far as the present situation is concerned, is it a good or bad thing to cancel the Spring Festival Evening? Different people have different opinions. On one hand, some people argued that it is a good thing to amuse the audience in that it is composed by a numerous adequate programs, such as the emotional song, the graceful dance, the funny short sketch, the amusing comic dialogue, the delightful magic, and the marvelous acrobatics and so on. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the Spring Festival Evening will have negative effect on the family harmony because it will not only do harm to having the talks between family members on the Spring Festival Eve but also to enjoying the gourmet meal in a fancy restaurant.
In my opinion, the Spring Festival Evening is a good thing. It may not remain a must for all people, but it can bring us a strong sense of festivity and serve as an alternative among the variety of holiday activities. With the increasing audience of the Spring Festival Evening, it will ruin a distinctive culture during the Spring Festival vacation.

当今世界，网上的信息动态发生着日新月异的`变化，各式各样的信息资料极为丰富，我们可以利用这些信息很好地为自己服务。例如，当我在学校学习有关法布尔的文章时，我就通过上网，了解到了法布尔耗尽一生光阴来观察研究昆虫，它专为昆虫写出了十卷大部头的书；知道了螳螂求食的方法，松树金龟家族、意大利的蟋蟀家族，通过网络，我对法布尔的《昆虫记》有了更深的了解。 还有，今年寒假里，妈妈所在的学校居然布置了好多篇论文，着急的妈妈像热锅上的蚂蚁，这时，我灵机一动，上网一搜，马上出现了很多适合妈妈的教案和论文，我粘贴到写字板上，再经妈妈改进，一片片教案和论文便迎刃而解。通过网络，我帮助妈妈消除了一个心头大患。 健康的上网带给了我知识，带给了我快乐，也带给了我便捷。可是不良的上网，却会带给人们痛苦，带给社会危害。 有的人沉迷网络，花费学业；有的人把虚拟世界的格斗带到现实生活中，构成犯罪；有的人通过网络诈骗感情、钱财，给社会带来了极大的危害，还有些学生，晚上在网吧“快乐上网”，白天在课堂上呼呼大睡。
网络是把双刃剑，健康的上网能使我们开阔眼界，轻松快乐，不良的上网却使人身心疲惫，无所适从。我强烈呼吁大家健康上网！
