为了帮助同学们的托福作文更上一层楼,今天小编就给大家讲讲对比论证在作文中的重要性,希望能对各位有所帮助哦!
对比论证是在无话可说时的救命稻草。特别是要对两件事物进行比较时,我们都可以用对比论证来进行展开,比较有说服力。对比论证通常分为两种:一是具体情况的正反对比,二是过去与现在的对比。根据不同的文章特点,可以将对比论证进行有效应用。
1、过去与现在对比:
对于过去与现在对比来说,涉及到change类字眼的题目都可以使用。相对来说,科技类的文章用得比较频繁。比如要说明科技对人们生活的改变,考生们可以写科技改变人们的通讯方式或者出行方式等等,然后就可以从过去的通讯方式或者出行方式以及现在的通讯方式、出行方式的改变进行比较。用这种论证方法时,要注意过去的时态以及相反的对比关系。
常用句型:
In the past… Nowadays, however, …
Topic 1: People think that a hundred years ago, the human race was steadily improving in every area of life. Nowadays, there is no certainty of this case. In which areas do you think we have made important progress nowadays? In which areas do you think we stillneed to make progress?
First of all, medical advance has changed the world to a totally new face. Before, the average life expectancy of people was only 30 years or so, people often dying from common diseases like flu and diarrhea. Nowadays, however, three or four generations can live happily together, with the eldest one more than 100, which is never far and few between. The wholesome medical care can easily cure even some rare diseases.
本题要注意审题,很多考生在考到这题的时候第一反应是题目太长,题目没有马上理解看懂,就开始慌了。其实静下心来,一句句理解马上能看出考题意图。其次要注意考试的题型,题目问了两个问题,要回答人类已经取得的进步和依然需要进步的领域,不要在作答时遗漏了。根据刚才分析的过去与现在的对比论证出题特点,不难看出题目给了明显关键词a hundred years ago和Nowadays, 提问中的progress也属于change的范围。所以我们分析医疗领域取得进步的时候,就可以很好地拿以前与现在的医疗状况进行对比,得出医疗领域上的巨大进步。
希望以上内容能对各位有所帮助噢!
