【正确答案】Introduction
The aim of this report is to summarise the changes in production and average prices of wheat between 1990 and 2000.
Findings
Focusing our attention on wheat production, it can be seen from the graph that the output rose steadily over the period. A general upward trend from 0. 9 millions of tomes in 1990 to 2. 3 millions of tomes in 2000 is clearly recognizable.
On the other hand, the average price of wheat totaled 1,400 ~/T in 1990, but in 1995 it increased rapidly reaching a peak of 2, 900 ~/T. In 2000 the price fell to 2, 400 ￡/T which was however more than the minimum price in 1990.
Conclusion
As can be seen from both graphs average price of wheat did not show the same characteristics as total wheat production.

【答案解析】[解析] 该习作较好地完成了题目要求的写作任务，结构比较清晰，所用词汇和短语较丰富，例如：focus on，reach a peak；能运用恰当的连接词如on the other hand，并且能够用到focusing on这样的分词放在句首做状语的结构。句型的使用也较丰富，如：it can be seen that…，as can be seen from…等等。但也有小的错误，例如：more than the minimum price.结尾部分表达欠佳，但并不影响整篇文章给人的好印象。
