我写的雅思柱状图小作文,这句话写的有错误么
in terms of the second bar chart,the scientists and technicians in developing countries were merely 10 per 1000 people which quarter of that in industrialised countries(40/1000) in 1980.
图的意思就是 1980 developing countries 是10,industrialised countries是40,我这样表达有问题么,另外这样写好不好?
还有这句!麻烦咯 comparing with developing countries,there was merely a slight grow by 5/1000 people.

答案

1.which quarter of that in industrialised countries(40/1000) in 1980.
这里应该是 which was quarter of that in industrialised countries(40/1000) in 1980.吧!a quarter of 四分之一的意思啊～
2.there was merely a slight grow by 5/1000 people.
这里应该是growth 啊,名词形式啊
刚考完雅思,记得蛮清楚的～
