如何减轻环境污染英语作文【一】
局部映衬是指在作文中描写自然环境时，可在任何部分用自然环境映衬人物的精神品质或文章的主旨、情感，从而让文章品格得到提升。使用局部映衬法，景物描写的文字并不求多，而求“精”而“得体”。某个地方可能只有一句景物描写，但就因这一句话，提升了这篇作文的整体质量。如一同学暑假回农村老家探亲，目睹了兄妹换亲的封建陋俗，写了一篇《探亲》的作文，文章结尾写到“第二天清早，我上路回城了。走时山村好静，走过童年的小树，我不禁回首：山村雾茫茫，人们还没有从梦中醒来呢。”作者描写山村茫茫的雾气，并以此暗示山村人们还未从梦中醒来，亦即还未丢掉封建陋俗，文章的主旨因此得到升华。
使用“局部映衬法”，需要注意的是须根据自己描写自然环境想要达到的目的来决定描写何种景物，并去寻找景物与达到的目的之间的关系。如果要表现一个人物的某种品格，可用和煦的春风映衬“温暖”“温馨”，用各种表现纯净美好的景物映衬人物的高尚品质……这一笔能使文章不仅停留在记叙层面，而有了一个精神的升华；如果要表现亲情主题，可用明媚的阳光象征与突出亲情所带来的温暖与温馨；如果要突出怀念主题，可适当描述秋景；如果要渲染紧张气氛，可以电闪雷鸣；如果要表现伤感，可以阴雨连绵……这个对应之处同学们可在平时进行优秀作文阅读的时候加以积累。

人类把许许多多的风景都污染了。比如：海水里、森林里、草坪里等等。
我想知道空气中粒子状污染物是怎么形成的：空气中的粒子状污染物数量大成分复杂，它本身可以是有毒物质或是其他污染的运栽体。其主要来源于煤及其他燃料的不完全燃烧而排出的煤烟。工业生产过程中产生的灰尘、建筑和交通扬尘、风的扬尘等，以及气态污染物物理化学反应形成的`盐类颗粒物。在空气污染检测中，粒子状污染物的检测项目主要为总悬浮颗粒物、自然降尘和飘尘。
我想对人类说：希望你们要爱抚花草树木，不要再污染环境了！
如何减轻环境污染英语作文【三】
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.
