中国央行星期二提高人民币汇率，此举符合北京最近表示将增强人民币兑换美元汇率更具弹性的承诺。

China's central bank set a stronger currency trading rate Tuesday, in line with Beijing's recent pledge to let the yuan trade more freely against the dollar.

截止2008年7月，中国已在三年内使人民币兑换美元的汇率上升21%。但是从那时起，这一汇率多少变得固定。

China allowed the yuan to rise by 21% against the dollar in the three years to July 2008, but since then it has more or less kept the rate fixed.

所以，我们会去一家中国的银行兑换人民币，卖出美元、买进人民币。

So, we would go to a Chinese bank and change the currency, buying yuan and selling dollars.
