考研英语阅读难句语法分析－名词性从句3

　　【难句】5. 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.

　　【结构分析】 本句主干很清晰，是主系表结构。其中表语部分由that引导的名词性从句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 作从句中的伴随状语，句末的形容词结构common to home networks后置作features的定语。 【参考译文】 这一方式的问题在于，消费者更喜欢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，便可以简单插入的装置。 【难句】6. Davies says guidance must strike a balance between being flexible enough to take account of the differences between disciplines and providing enough detail to be of use. 【结构分析】本句不难，主句谓语says后是省略了that的宾语从句guidance must strike a balance between being flexible enough to take account of the differences between disciplines and providing enough detail to be of use。注意两个between的使用。第一个between与后面的and 相连，构成being flexible enough to and providing enough detail to 结构，第二个between后跟disciplines表示 各学科之间 ，并且前后都使用了be enough to do的形式。 【参考译文】戴维斯说，指导规范必须在足够灵活考虑各学科的不同点和提供充足的可操作的细节之间寻求一种平衡。 【难句】7.
