分析 has he devoted to studying robots
解答 答案:has he devoted to studying robots.致力于做某事用devote to doing sth致力于做某事,結(jié)合句意可知動作發(fā)生在過去,持續(xù)了一段時間,故用現(xiàn)在完成時have/has+過去分詞,主語he,故has,這里是特殊疑問句,特殊疑問詞+一般疑問句,將has提前,study robots研究機器人,故答案是has he devoted to studying robots.
點評 devote 指"決心將全部身心、活動、精力等獻(xiàn)出",如:
devote one's life to a cause
把生命獻(xiàn)給事業(yè).
【習(xí)慣用語】.
devote to把…獻(xiàn)給;
devote oneself to 致力于,獻(xiàn)身于; 專心于
He devoted his life to literature.
專心致志于文學(xué).
He has devoted his whole life to benefiting mankind.
他為全人類的利益獻(xiàn)出了自己的一生.
