(1举止文明，人多的时候不拥挤、不起哄、不制造紧张或恐慌气氛。
(2尽量避免到拥挤的人群中，不得已时，尽量走在人流的边缘。
(3发觉拥挤的人群向自己行走的方向来时，应立即避到一旁，不要慌乱，不要奔跑，避免摔倒。
(4顺着人流走，切不可逆着人流前进，否则，很容易被人流推倒。
(5假如陷入拥挤的人流时，一定要先站稳，身体不要倾斜失去重心，即使鞋子被踩掉，也不要弯腰捡鞋子或系鞋带。有可能的话，可先尽快抓住坚固可靠的东西慢慢走动或停住，待人群过去后再迅速离开现场。
(6若自己不幸被人群拥倒后，要设法靠近墙角，身体蜷成球状，双手在颈后紧扣以保护身体最脆弱的部位。
(7在人群中走动，遇到台阶或楼梯时，尽量抓住扶手，防止摔倒。

人群开始***动时，就要做好准备保护自己和他人。

(10当发现自己前面有人突然摔倒了，马上要停下脚步，同时大声呼救，告知后面的人不要向前靠近。
为此，专家特别提醒：当发现前方有人突然摔倒后，旁边的人一定要大声呼喊，尽快让后面的人群知道前方发生了什么事，否则，后面的人群继续向前拥挤，就非常容易发生拥挤踩踏事故。如果此时你正带着孩子，要尽快把孩子抱起来，因为儿童身体矮小，力气小，面对拥挤混乱的人群，极易出现危险。面对混乱的场面，良好的心理素质是顺利逃生的重要因素，争取做到遇事不慌，否则大家都争先恐后往外逃的话，可能会加剧危险，甚至出现谁都逃不出来的惨剧。

我是一只麻雀，我在人类世界中穿梭。他们说人类的智慧是所有动物中最高的`。高等动物就是人类对自己的称呼。在我看来，人类分明就是地球上的最愚蠢的动物。
你看那山坡上，那寸草不生的土地没有一点绿草红花的点缀显得那么荒凉，一切的源头都是那上坡顶上的化工厂。你看它烟囱飘出来的浓浓黑烟。破坏着地球的臭氧层衣服。我向化工厂飞去。看到的一只同类，我飞了过去。只见它奄奄一息的对我说”快走，这烟有毒“我看着它，依依不舍的飞向远处，我相信那些愚蠢的人类会受到惩罚的。我用恨恨的眼光审视着那化工厂。可惜我只是一只麻雀，力量微小。
几个月过去了，化工厂依然运行着，但是人类却已经为他们的所做所为付出了代价。你看那都市里的雾霾。是地球觉得人类已经迷失了么?然后放出雾霾提醒人们么?
所幸，人们已经知道错误，有不少人都在保护环境。但是泼出去的水还装的会来么?人类只能为自己的行为付出代价了，如果人类还不知悔改，那么地球灭亡之日也是人类灭亡之时。

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.
如何防止空气污染英语作文【六】
随着暑假的到来，越来越多的学生都选择了游泳，来作为自己暑假里的娱乐方式，这本是非常好的，可是，却有很多人，没有到正规的地方游泳，甚至去池塘，河流等危险的地方游泳。
目前全国每年有1。6万名中学生非正常死亡，溺水和交通事故死亡居前两名。
江河湖泊往往装出一副平静、温柔的样子，让人忽视了温柔的背后是多深的地狱。有多少人落入了这无底的漩涡、这可怕的魔爪。
身边，也许这些沉重的画面时常可见，就在我们身边，悲剧正在上演着。
当你看见朋友要私自去河里游泳时，你会阻拦吗?
当你看见有人在水中挣扎时，你会张皇失措吗?
当你在没有家长陪同，有炎热难耐时，你还会任性的往水中跳吗?
一些学生因为逞强好胜，不知水深，潜入水中，还做出各种各样的姿势，导致体力不支。碰到这种情况的学生，有的被救了，但另外的学生呢，则再也无法重新开始了。这难道是天意吗?难道活下来只能靠运气吗?
离去的学生或许很后悔，但再也来不及改正了，只留下在世的亲人悲痛不已;死里逃生的学生，带着侥幸心理，但恐怕再也不会有第二次了吧;对于那些从没有遇到过这件事的人，趁来得及，更加珍惜自己的生命。
溺水时可以避免的，只是学生缺乏“游泳安全”的意识以及防溺水知识。
身边的河流只便于用来欣赏，享受游泳的乐趣还是留给那些有和准备的人吧，他们总是预料到一些可能发生的事情，准备好应对的方法。
在不知水深的情况下，绝对不可以以身试险;在有障碍物或有漩涡的激流中，也不可以轻易下水。游泳之前一定要做好安全措施，如救生圈，必须要有懂水性的家长陪同，还要做一些准备活动，否则有可能会导致头晕、恶心、心慌等不适应的现象。若在水中大腿抽筋，应立即上岸，在无人时，也要学会自救的'方法：先吸一口气，仰浮在水上，用抽筋肢体对侧的手握住抽筋肢体的脚趾，并用力向身体方向拉，同时用同侧的手掌，压在抽筋肢体的膝盖上，帮助抽筋的腿伸直。
生活中世事难料，我们要好好把握自己的生命，对自己的生命负责，不能因为一时大意而让自己身处险境。看着身边一个个生命就这样在世界上消失，请记住这一个个教训。
预防溺水，珍爱生命，希望我们每个人都能够重视这些问题，不要为了一时的快乐，而让自己的生命陷入危险之中。
