1【长难句】

　　The trouble with that approach is that consumers tend to prefer devices that require simply plugging them in, without complicated setups of wireless channels, security, and other features common to home networks.

　　2【结构分析】

　　The trouble with that approach是主语，注意此处的that相当于the，不是引导从句。表语部分由that引导的表语从句that consumers tend to prefer devices…充当。device后是that引导的定语从句 that require simply plugging them in…,关系代词that在从句中作主语。逗号后的介词短语 without complicated setups of wireless channels, security, and other features…作从句中的状语，句末的形容词结构common to home networks后置作features的定语。

　　3【词汇】

　　approach 方法，方式

      plug in 插入

      home network 家庭网络

　　4【参考译文】

　　这一方式的问题在于，消费者喜欢的装置通常是可以简单插入，不需要创立复杂的无线电频道、安全保护以及家庭网络所共有的其他特性。
