________, a small advertisement held my attention, which read “Easy job．Good wages．No experience necessary．”
A.Looking through the newspaperB.While I was looking through the newspaperC.To look through the newspaperD.I was looking through the newspaper在线课程B
非谓语动词(looking through the newspaper/to look through the newspaper)的逻辑主语应该是someone，而此句主句的主语是a small advertisement，根据非谓语动词作状语的逻辑主语要和主句的主语一致原则，所以排除A、C选项。根据句意，此句为复合句，用while引导时间从句，故选B
