问题 Libby lied to investigators about his role in disclosing the identity of a CIA officer in order to______the White House from political embarrassment.

选项 A、aviate
B、recover
C、berate
D、insulate

答案D

解析 本题的四个选项中,aviate意为“飞行”;recover意为“重新获得,恢复”;berate意为“严厉指责,申斥”;insulate意为“使绝缘,隔离”。本题的句意是,利比在揭露中央情报局官员身份时对调查员隐瞒了自己的任务,为的是使白宫不会陷入政治困境。因此正确答案是D项,如Children should be carefully insulated from harmful experiences(应该小心地使儿童与有害身心健康的活动隔绝)。
