每日一句：

61. Adding a Bluetooth chip to a phone now costs very little—around $2, down from $20 in 2001—but allows the manufacturer to increase the price of the handset by far more, and opens up a new market for high-margin accessories.

【分析】

 破折号之间是插入语，作上文costs very little的具体解释说明。Adding a Bluetooth chip to a phone是非谓语动词作主语，costs…but allows…, and opens up…是并列结构。

【词汇】

 opens up a new market for开辟…的市场

high-margin高利润

accessory配件，配饰

【参考译文】 在手机里添加一个蓝牙芯片的成本很低——只需要2美元左右，而2001年是20美元——但能使制造者远远提高手机现有的价格，并且打开一个高利润附件的新市场。
