从一个侧面,就事物的某一个特点做些解释,这种方法叫诠释法。
定义法和诠释法常采用“某某是什么”的语言形式。形式相同,如何区分呢?一般来说,“是”字两边的话能够互换,就是定义;如果不能互换,就是诠释。
例如,“人是能制造工具并使用工具进行劳动的高级动物”这句话,改成“能制造工具并使用工具进行劳动的高级动物是人”,意思不变。“雪是在云中形成的一种固态降水物”这句话,如果改为“云中形成的固态降水物是雪”就不成。由此可以辨别,前一句是定义说明,后一句是诠释说明。
Why Are Trees Important?
Trees are very important to us. Do you know why? Let me tell you.
Trees take in carbon dioxide from the air and make oxygen. That's important. People and animals need oxygen to live. Many small animals and insects live in the trees. Some of them also get food from trees. Trees can also stop water and soil from going away. If we have a lot of trees, we stop deserts from being large. I think this is very important. You know, trees are green. They can make our country even more beautiful.
Trees are our good friends. We should plant more trees and take good care of them.
点评:文章先阐明论点,接着论证,最后重申自己的观点。
范文2
It's Our Duty To Protect Our Environment
It's our duty to protect our environment. Where we live? The earth. The earth is the only one place we live in. So you know how important the environment is. But now, some people are harming the environment, like cutting down trees, drawing pictures on public walls, littering onto the ground. It's terrible if we still do it. Now, it's time for all the people in the society to protect the environment. It's our duty. It needs each of us to make a contribution to improving the environment. We should make our environment more and more beautiful.
点评:作者多用学过的'词语不但保证了正确,还巩固了所学的知识,并且注意句型的多样化,如长句,短句,疑问句,使用了“if,so, now, but”等词,整篇文章读起来朗朗上口。实际上,写文章就像串珠子,连接词就在于把一个个单词串起来。
所有的GRE阅读文章都不是照搬照抄原有的学术论文。其编写过程一般是出题机构先找到基本符合要求的源文章, 然后根据出题机构的要求对文章进行相应的改编。具体来说可分为几下几个步骤:
1. 搜集源文章 出题机构一般有自己固定的信息源和搜集信息的渠道。如ETS使用一个名为Source Finder的软件在Internet上自动检索数字论文库EBSCO中的'文献,并从中提炼出符合各种考试风格要求的样本文章。
2. 改写 出于版权限制,ETS用于实际考试的文章长度最多只能引用10%的原文长度。这种带着镣铐跳舞的结果是大量文章内容被改写,重写和删节。改写一般会大量使用分词及从句,使句子变得更紧凑、更严密。尽管改写后的文章会变得错综复杂,但出题机构会尽量保持文章中原有的鲜明态度以及较好的层次结构。如:文章一开始给出一个老观点,后来有人提出新观点,驳斥老观点,文章作者对这个新观点或完全同意、或持部分保留意见、或是做出有正有负的混合评价。
