1【长难句】
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. 2【结构分析】
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。 3【词汇】
opens up a new market for 开辟…的市场
high-margin 高利润
accessory 配件,配饰 4【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。
