题目

英语翻译
Economies contain two sorts of activity:tradeable-manufactruring and services that can be supplied readily at a distance;and non-tradeable-haircuts,childcare and so forth.With economic development,productivity in the former tends to rise faster than in the latter.Assume,for simplicity's sake,that we are talking about a small country with a fixed exhange rate.Then the price multiplied by the exchange rate.Prices of non-tradeables will rise relative to those of tradeables,because their ralative unit labour costs will be increasing.This is why haircuts are cheap in poor countries and expensive in rich ones.

答案

经济包含两种行为：可快捷远程提供的可交易制造和服务;以及非可交易的理发,育儿等.随着经济的发展,前者的生产力上升趋势较后者更快.假定,为方便起见,我们谈论一个汇率固定的小国,然后用价格乘以汇率,相对于那些贸易品,价格的非贸易品将会增长,这是因为他们的相对单位劳工成本将会增加.这就是理发在贫穷国家便宜,而在富有国家昂贵的原因.
（三处拼写错了..第一行的manufacturing,第四行的exchange,倒数第二行的relative）
