问题 It is advisable to______an electric wire with rubber in order to secure safety.
选项 A、desolate
B、resolute
C、insolate
D、insulate
答案 D
解析 四个选项的意思分别是：desolate毁坏，破坏；resolute坚决的，刚毅的；insolate暴晒；insulate使绝缘。句意是，为了确保安全，用橡胶把电线绝缘是很好的建议。所以正确答案是D选项，如：Asbestos can be used to insulate a cooking stove．(石棉能用来使烹调用的炉灶绝热。)
