答案与解析41。designed考查过去分词做定语的用法。设空处做后置定语修饰robotlawnmowers,design与robotlawnmowers之间是逻辑上的动宾关系,且design所表示的动作已发生，故填designed.42.being考查动词—ing形式做补语的用法。此处是with复合结构做状语，因globalwarming与be之间是逻辑上的主谓关系，且be所表示的状态与谓语动词所表示的状态同时存在,故填being。43.quietly考查副词.设空处修饰谓语动词work，故填副词quietly.44.wasfound考查一般过去时的被动语态。由Aftercarefulassessment可知,此处用一般过去时，又因noise与find之间是被动关系，故填wasfound。45。toreturn考查不定式做宾语补足语的用法。warnsb/s
