假如我是发明家，我要发明“空中步行机”，给远离家乡的人们带去方便。它的造型就像哪吒的风火轮一样，但是里面安装了智能芯片，你只要在中间的小键盘里输入想要去的地方，它立刻就会以每秒1000米的速度将你安全送到目的地。俗话说：“独在异乡为异客，每逢佳节倍思亲。”我要把它送给远在边疆守卫祖国边防战线的将士们，让他们能在过年过节的时候飞回家与亲人团聚，吃上香喷喷的团圆饭。

假如我是发明家，我还要发明“神奇复印镜子”。这种镜子表面看上去跟普通的镜子差不多，仔细一看，它的右下角有一个红色和一个绿色的按钮。红色按钮是启动，绿色按钮是停止。只要你把一个物体放在镜子前面，按下红色按钮，这个物体就会在10妙钟内变成两个相同的`物体。如果你不按下停止按钮，那么它也就会不断的复制下去。怎么样？够神奇吧！我可要利用它来复制一些濒临灭绝的珍稀动植物，让珍贵的“活化石”——银杏能在祖国各地茁壮成长；让可爱的熊猫盼盼能成为家家户户的宠物。

假如我是发明家，我还要发明更多更有用的神奇道具，让世界充满神秘，让生活充满幻想，让人类倍感科学的魅力！

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.
