12月18日，上海國際酒類交流會正式開放，它是一個為包括葡萄酒、白酒和進口酒等優質酒類產品交易服務的交流平臺。該交流會在2010年就開始試運行，并且據說是中國第一個專為高端投資者服務的交易中心。上海國際酒類交流會會長李文峰稱，2013年該平臺的營業額將達到300億元人民幣，而在2015年這一數據將達到約1000億元。

請看相關英文報道：

Shanghai International Wine Exchange , an exchange platform for trading premium alcoholic products including wine, baijiu and imported liquor, formally opened on Dec 18 in Shanghai.SIWE started trial operations in 2010 and is said to be the first exchange center designed for higher-end investors and traders in China. Li Wenfeng, president of SIWE, said some 30 billion yuan turnover would be achieved in 2013 and the figure would reach some 100 billion yuan in 2015.

解析：

在上述報道中，"higher-end"就是“高端”的意思。而“低端”則是"low-end"。表示“中端”可以直接用"middle"。

例句：

The higher-end companies, which suffered more going into the recession, are now recovering more quickly coming out.此前在衰退中受影響更大的高端公司，如今卻復蘇得更為迅速。

So far our company only makes chips for low-end phones .現在我們公司僅為低端手機制造芯片。

It is aiming Fresh&Easy squarely at the middle market .鮮易食品的市場為中端市場。
