议论文,如果是应试作文,首先要中心观点紧扣作文题
其次要围绕中心观点展开分论点,论点的论述不能空谈,最好能结合自己积累的素材(如名人轶事、名言之类）,素材要为中心服务,不要生搬硬套,否则还不如没有素材.然后结合素材展开自己的观点,观点的论述是最能体现一个人的思维能力的.在这个大多数学子都在狂背优美文章、经典段落的时代,观点的独到深刻往往能使你脱颖而出。
阐述玩观点,最后就是结合实际来呼应观点了,这样能使文章更加鲜活.
在结构上,总-分-总吧,最后把分论点整合下,为主题服务,
在语言上,语言不必追求华丽,有理有据,流畅即可吧,
2017考研英语二大作文范文及点评内容？
Growing urban population and declining rural population
From the graph, we can see that the urban population was growing and the rural population was declining from 1990 to 2010。
The number of the urban population rose from 300 million in 1990 to about 460 million in 2000, and to about 685 million in 2010, while the rural population decreased from about 820 million in 1990 to 800 million in 2000 and to about 690 million in 2010。
It's obvious that in the past two decades, the urban area witnessed a steady growth, but in the latter decade, the rural population had a remarkable decline。
There are two reasons for this phenomenon。 On one hand, the economic boom led to the regular improvement of people’s living standard, and further resulted in a steady growing urban population。
On the other hand, from 2000, the countryside urbanization oriented by the government gave rise to a conspicuously declining rural population。
In conclusion, based on the above analysis, the urban population will be growing, while the rural population will continue to drop in the future。
