The distinction between Latin America and the other two regions – Africa and the slightly bigger exporter East Asia – was clear, as Latin America sold to the international market far more tonnage of bananas than did the other two regions. In the two years, the respective sales were 5.5 million and 10.5 million tons, and they could be more than ten times of the sales in the other two regions.
Most conspicuously, when a ton of bananas are sold at the retail price,farmers make a mere 4 percent of the price, far less than the profit margins, which were more than four times of the production cost. Another small part of the price was the export cost, and tax, cross-border transportation and cross-border transportation accounted for moderate portions. The rest 35 percent is cost by distribution and retail.
注意题目中的主题词汇(比如本文中的exporter, sold to the international market, profit margins, cross-border transportation, cross-border transportation)也是有替换的空间的。
