The promising idea mentioned in the first paragraph ______. [br] It can be inferred from the passage that the new products of Panasonic, Netgear, Marantz ______.
选项
A、can directly move data by home electrical wiring
B、are adapters or a similar system to transfer data
C、provide the present Wi-Fi criteria for wireless networking
D、were produced for home electrical lines last month
答案
B
解析
根据题干关键词Panasonic,Netgear和Marantz定位到文章第6段,第7段和第8段。推断题。文章第6段首句说松下开始卖它的HD-PLC以太网适配器…,第7段首句介绍说Netgear下个月也将卖它的一种类似的系统…,第8段也提到Marantz的ZR6001SP接收器…,以及后面解释的工作原理和前两种相似,因此答案为B。A错在“directly”,因为这三种产品都需要适配器或类似的系统;这三种产品采用而不是提供Wi-Fi标准,因此排除C;Netgear的产品还没有生产出来,下个月才开始要卖,因此排除D。
