2014年考研英语二大小作文真题及答案解析

2014年考研英语二大小作文真题及答案解析 英语二大作文 Directions: Write an essay based on the following chart.In your essay, you should 1) interpret the chart, and 2) give your comments。 You should write about 150 words on the ANSWER SHEET. (15points) As the bargraph indicates, both city and rural area witnessed a distinguished phenomenonin population fluctuation. Indeed, population in city increased at a breakneckspeed and surpassed that of rural area during the period from 1990 to 2010while population in rural region slightly decreased down to a scale which wasclose to that of city。

Whataccounts for this disparity? The answer involves two factors. The firstcontributing factor is the substantially fast developing steps of cities inChina. No one can deny that since Chinese economic reform from 1980s whichmostly benefits people in city. The second reason is that Chinese farmers enjoythe harvest from new policies that are established to benefit farmers. Peoplein rural areas are allowed to migrate for work and residence by the law and anincreasing number of farmers choose to work in city and become migrant workersjust because they would make much more money than ever before in city. Allthese are the result of urbanization。 Basedon the analyses above, we can safely draw the conclusion that the process ofurbanization will continue in the years ahead, and every single Chinese benefitsfrom the fast development of China。 英语二小作文 Suppose you are going to study abroad and share an apartment with John, a local student, write him an email to 1) tell him about your living habits, and 2) ask for advice about living there。 首先,注意试题要求,一定要在首段告知写信目的后,在第二段给出自己的生活习惯,尾段一定按着题目要求向对方请求一些建议,否则会被认为是没有涵盖所有信息点,会被扣分。 其次,第二段写自己的生活习惯时,不宜写的太过极端和个性,否则你的信件会让目标读者反感,因此起不到大纲要求的“对目标读者产生预期效果”,也会被无情扣掉很多分。
