如何防止塑料污染英语作文【一】
生命无处不在。在川流不息的人群中，那一颗颗跳动的心灵，那一张张微笑的脸庞，是一个个鲜活的生命;在散发着智慧气息的森林里，沐浴着阳光茁壮成长的小树，祥和的参天古树，是一株株充满生机的生命;在那浩瀚无垠的大海里，无忧无虑畅游的小鱼，婀娜多姿的珊瑚，是无数灵动而美丽的生命。 当你看见一位母亲十月怀胎，婴儿呱呱落地时，你会知道，这将宣告着一个新的小生命的诞生!你是否会感叹，感叹生命的来之不易?可是，生命是宝贵的，生命是脆弱的!
今年的4月26日，在安徽省老畀河发生了一起学生溺水事件，5名小学生结伴到老畀河游玩，其中1名五年级女生在河边洗手时，不小心踩空滑落水中，其他同伴伸手去救落水学生，结果这5名同学相继坠入水中，溺水身亡。5条鲜活的生命瞬间就消失了，不仅给他们的家庭带来巨大悲痛，也为我们敲响了警钟。他们的生命就如初开的蓓蕾，前程无限，然而却被无情的河水所吞噬，难道不令人痛心吗?
也许有人觉得这些事情离我们很遥远，但我们身边也确确实实有过这样残酷的实例。据省教育厅去年的统计，溺水已成为广大中小学生尤其是农村小学生非正常死亡的主要原因。2010年永嘉县学生非正常死亡20人，其中溺水死亡的就达13人。
正因为有了这些惨痛的例子，我倡议全体同学做到“五不”承诺：1、不私自下水游泳;2、不擅自与同学结伴游泳;3、不在无家长或老师带领的情况下游泳;4、不到无安全设施、无救护人员的水域游泳;5、不到不熟悉的水域游泳。而在游泳之前，学习一些预防溺水的知识是不可或缺的。
人不能像野草那样，“春风吹又生”，人的生命只有一次，而且生命要靠自己掌握。身边处处有安全，我们平时就要做到“安全学习，安全生活”，杜绝危险的行为，让瓯北中心小学变成一个安全和谐的校园。

生命重于泰山，安全高于一切。今天我们学校举行全校性的紧急疏散演练，目的是为了进一步提高全体师生的自我保护意识，提高面对突发事件的应变能力，增强在紧急状态下的心理承受能力，帮助全体师生提高自救、自护的能力。同时我们也希望通过今天的演练，大家能熟悉逃生疏散线路，一旦遭遇突发事件，能在最短的时间内进行逃生自救。
这次疏散演练比以往要具有挑战性，是在老师同学不知道在具体时间情况下发生了危害，考验我们老师学生的应变能力。但大家临危不惧，当广播中响起警报时，全体人员能严格按照突发事件应急预案，进入各自岗位进行及时疏散，各班学生在老师指挥下按照指定的安全出口，有序地离开事故现场，紧急撤离到安全地带，全部学生在规定的时间内到达了安全地带。从信号发出到第一个学生到达集合地，历时12秒钟，全体学生撤离完毕共花140秒钟时间，整个过程紧张而有序，撤离队伍一个接着一个，安全、迅速地到达集合地点，经过实地点名，全体学生和教职员工悉数到达指定位置，活动取得圆满成功在演练过程中保持了安全良好的秩序和快速反应的能力。本次演练活动共有263名学生和部分老师参加，整个演练活动达到了预期效果。
在取得成绩的同时，我们也通过演练发现了一些问题：表现为部分学生在活动中没能把演练当作一次实战演习，在疏散的过程中紧张程度不够，撤离速度不够快慢。这次演练虽然结束了，但安全工作没
有止境。各班级要认真总结教训，着手建立长效机制，完善责任制度，确保校园安全。
凡事“预则立，不预则废”。 灾难来临时，虽然我们无力对灾难说些什么，但关键在于我们如何防患于未然，知道当自然灾害来临时，如何给自己和他人的生命留下更大的生存时空。5 •12汶川大地震发生的那一刻，四川省安县桑枣中学全校304多名师生能死离逃生俱缘于他们每学期进行一次的疏散演习。桑枣中学教会学生逃生避险自救的能力，为我们树立了生命教育的榜样，也让我们回忆并懂得了08年中央电视台新年开学第一课《如何用知识来守护生命》的深刻含义。血的教训提醒我们要有备无患、临危不惧、坚持不懈。天灾虽不可避免，但历史却不该让它重复。今天的这场疏散演练给我们学校的.安全教育上了生动现实的一课，这对我们这样一所规模较大、正在发展中的学校显得尤为重要和必要。希望全体师生能以这次紧急疏散大演练为契机，进一步做好学校的各项安全工作，把安全隐患消除在萌芽状态，防患于未然。让我们用知识守护生命，用爱护卫心灵，牢记安全教育，学会应急避险的常识和技巧，努力营造一个平安、和谐、祥和的校园环境!
如何防止塑料污染英语作文【六】
炎热的暑假马上就要到了，同学们都想找个凉快的地方去避暑，有的同学就想到水库或溪边去游泳，可是有的同学却不知道水到底有多深，就冒昧的下去游泳。但游泳是有一定的危险性，每年夏天，不知有多少人因为游泳而失去了鲜活的生命。所以告诫大家：没有成年人的陪护千万不要去游泳。
我曾经听外婆给我讲过这样一个故事：在他小的时候，家里很穷，没有电风扇更别提什么空调了，呆在家里嫌热，有一天中午，他就和小伙伴们一起趁家人午休的时间偷偷溜到河边玩耍，小朋友们看到清清的河水很高兴，就开始玩起了打水仗，玩了一会儿，他们就想去游泳，其中有个十一二岁的大哥哥带头先下了水，于是别的小朋友也跟着一个个下去游泳了，在水里你追我赶，玩的可开心了。可是有的小朋友根本就不会游泳，快天黑了，小朋友尽兴的回家了，到了吃晚饭的时间，隔壁邻居家的阿姨找不到自己家的女儿了，我心想坏了，是不是刚才在水塘游泳还没回来，于是我就和他们一起去找，刚到河边就看到了他的衣服还在岸边，可是左找右找就是看不到人影，大家都慌了，连忙找来各种工具进行打捞，几个小时过去了，最后终于在一处水流湍急的石缝边找到了，可是他已经停止了呼吸，永远的离开了我们。
这个故事给了我深刻的教训，在这里，我提醒大家：游泳一定要有家长看护，不会游泳的最好不要下水，即使游泳也应在有安全保障区的游泳区内进行，严禁在非游泳区内游泳。这样我们的生命才有安全保障。
为了防止溺水，我们应该做到：不宜在太凉太深的水库或鱼塘游泳，如感觉水温与体温相差较大，慢慢入水，渐渐适应，可以在水中玩游戏，但不能搞恶作剧。在露天游泳池遇到雷雨天气时，应立刻上岸，到安全的地方躲避，以免发生意外。
同学们一定要记住血的教训，防止溺水、珍爱生命。
如何防止塑料污染英语作文【七】
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.
