各位帮忙修改一下雅思A类的小作文.是关于：wheat exports.

The graph reveals the differences of the wheat exports over the three different areas from 1985 to 1990。We can see the standard of living in those different areas from the side。Firstly,let’s see the data of Canada。The arrowhead began at 19 million ton。After one year,it had decreased to 17。Then it bounced back to reached the peak which was 25 million ton in 1988。It took 2 years to jump to 25 but took only one year fell to 14。In the last year,the arrowhead went back to where it started。。The second target was the data of Australian。The arrowhead pointed at 15 in 1985。It took one year to climbed to 16。From 1986 to 1900,the inclination did a downward trend with a constant acceleration(with 后一般是名词）。However,It had rolled down the production by 5 million tons from 1986 to 1990。The last was the data of European community,it was a variational (fickle通常用来描述人） one。From the beginning at 17 million tons upwards trend,it went down 3 million tons in the first year,but picked up 1 million ton in the second year。From 1987 to 1988,the arrowhead kept at 15 million ton。But from the last two years,it had increased to from 15 million tons to 21 million tons。哥们语法错误较多,而且用词很多不准确,容易给人误解。如是雅思作文,望多用些从句,还有句子连接的介词比如 however,yet,but,and ,in the sense of,in terms of,in addition,secondly,firstly,next,finally,at last,because,for,not only 。。。but。。。as well,although,because of,in spite of,despite,it seemed certain that 这些联系此很关键,可以加强句子的联系性。还有在介词的应用上,望多阅读范文,被诵课文。
