我利用寒假，制作了一个实验装置来验证吸烟对肺部的影响：
设计目标：
通过演示试验了解吸烟对身体的严重危害性。从而引导同学们开展“拒绝吸烟”、“劝戒行动”进行创新活动设计。在活动中知道自觉拒绝香烟，维护自己的权益、维护环境。
装置材料：
一个透明的瓶子矿泉水瓶（含盖子）、香烟、橡皮膜、面巾纸等
装置制作：
取矿泉水瓶盖，在瓶盖上钻一个孔，使一支香烟能够正好卡住，将矿泉水瓶去底，在上面蒙一层橡皮膜用胶水粘牢，松紧要适度，沿瓶盖内部边缘粘一层面巾纸，盖上瓶盖，这样一个简易的实验装置就制作完成了。
实验操作过程：
将一支香烟点燃，插在瓶盖事先打好的孔上，点燃部分向上，模拟人口吸烟过程，来回拉动矿泉水底部的橡皮膜，模拟人的呼吸，这时会发现有烟进入瓶中，而渐渐的会使面巾纸变成黄色，产生很多烟油附在纸巾上（面巾纸模拟人体肺部肺泡），而如果长时间拉动橡皮膜的话瓶子内就会形成一层尘垢。（瓶子模拟人体肺部）。
实验总结：
本实验通过运用材料，模拟了人体吸烟对人体危害的.过程，橡皮膜的拉动，模拟人不断呼吸、面巾纸模拟人体肺部肺泡、瓶子模拟人体肺部，通过一系列实验最终验证了吸烟有害健康。并且说明了吸烟对人体肺部的影响，从而告诫人们切勿吸烟本实验装置材料完全取材于生活，都是一些身边的物品，并且切实地说明了吸烟有害健康这一主题，制作简单，容易操作，实验效果明显使大家直观的了解实验结果，使大家明白吸烟几乎损害人体全部重要器官。对于这一点很多人不以为然，因为这需要时间证明，但我们绝不做此实验的试验品！能够使同学们通过自己动手做实验明白烟对人体的危害，从而达到使同学们远离香烟，拒绝吸烟，永于向香烟说“不！”还可以激发同学们的学习兴趣，促使同学们不断创新，不断努力，向着科学的世界冲！冲！冲！为了我们自己的健康，我们呼吁，全体同学都要自觉地远离香烟，并劝说吸烟的亲友尽量戒烟。毕竟，香烟对我们有害无益；毕竟，没有烟雾的空气会更加清新，没有烟草的生命会更加绚烂！同学们，让我们行动起来，从现在做起，从自我做起，严格控烟，向更多的人宣传吸烟有害健康的公益知识，呼吁全社会都珍惜自己和他人的生命，自觉控烟，坚决拒绝“二手烟”。使我们的天空更加湛蓝！使我们的明天更加辉煌！

从《语文新课标》对写作教学的要求中，我们可以发现对于起步作文着力强调学生习作兴趣的同时，更突出学生的主体体验。当学生有了自己心里想说的话，有了对周围事物的观察，有了现实生活的关注与热爱，才能提起写作的兴趣，才会“乐于表达”。叶圣陶先生也说：“生活犹如源泉，文章犹如溪水，泉丰富而不枯竭，溪水自然活泼地流个不停。”叶老的话揭示了作文与生活的关系。对三年级的小学生来说，认识世界的主要途径是观察，只有亲身去接触事物，仔细的观察事物，才能获得真实、深刻、细致的第一手资料，写作时才有话可写，写出的文章才会真实生动。例如学习描写一种水果，可以让学生每个人都带一种水果回校，引导学生用自己的眼睛去有顺序的观察和了解水果的外形、色泽、味道、吃法等等。这样，他们的探索兴趣将是空前高涨的，虽然他们的收获会有差异，但是有一点是可以肯定的，那就是他们学会了观察，学会了思考，学会了搜集信息。有了诸多的感受与体验，学生怎么不会乐于打开他们的话匣子呢。

“作文就是用笔写话”。作文是技能，不是知识，空讲文章作法是无济于事的。一定要勤动笔，少束缚，要放手让学生写，用自己的语言、自己的思路写自己想写的内容，既是“我手写我口，我手写我心”。要把练笔渗透到阅读教学之中、各科学习之中、日常生活之中，只靠每学期几次习作，是不可能形成很强的作文能力的。作文还是一种习惯，良好的习惯有赖于长时间的培养，习惯的养成靠历练，而一旦习作习惯养成必然具有很强的作文能力，将会影响一生。因此，教师要把勤于动笔的习惯培养贯穿于习作教学的全过程。要让学生在认真观察和积累的基础上勤于练笔。例如让学生将观察到的情况用一两句话记录下来，作素材笔记等。另外写日记也是练笔的最佳途径，还是积累材料的最好方式。由于日记的内容很广，可写听到的、可写看到的、也可写想到的。总之，自己的喜怒哀乐都可无拘无束地表现出来。这样就让学生有一个自由表达的空间，也能够写真实的`事情。比如：每组织学生看完一场电影，开展了一次体育竞赛，搞完一次大扫除等，都可让学生把当时的情景和感受用日记的形式写出来。
如何保持健康英语作文初一50词【六】
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.
