问题
One of the most interesting new uses for glass is in telephone communication. Scientists have developed glass fiber as thin as human hair which is designed to carry light signals. When the light reaches the other end, it is first changed into electrical signals, which are in turn converted into sound messages.
选项
答案
玻璃有一种有趣的新用途是用于电话交流中。科学家已经设计研制出细如人发的玻璃纤维来传送光的信号。当光到达另一端时,首先会转换成为电子信号,然后再被转换成为声音信息。
解析
signal信号;convert使转变,转换……。which are in turn converted into sound messages是非限制性定语从句修饰前文的electrical signals。
