(1) Although many have tried, few have succeeded in attempts to       .   

    【分析】本句中tried后的宾语可根据后半句的语义推测得知，所以可以省略，避免重复。   

    Although many have tried, few have succeeded in attempts to find perfect solutions.   

    (2)       , be it       , will bring a lot of happiness into our lives.   

    【分析】本句是一个超难句型，中间一节省略了whether和might，并进行了倒装，将“be it”恢复后应为whether it might be。Be it…，可译为“比方说”，用来给出更多细节。   

    The application of electric power, be it to light our rooms or to listen to music, will bring a lot of happiness to our lives.     

    (3) Christie stared angrily at her boss and turned away, as though to go out of the office.   

    【分析】as though引导方式状语从句，谓语常用虚拟语气，本句中主句的主语与从句的主语相同，故从句中的主语和谓语省略，即省略了she wanted；如果补全，即为：as though she wanted to go out of the office.
