example for;all overb.was set an example to;acrossc.set an example to;throughoutd.set an example for;across提示:throughout the country或all over the country的意思是“全国”；“某人给某人树立榜样”应为sb.set an example to

talk,was____________________ she graded her students on.a.that             b.how              c.what               d.which提示:此处用what引导表语从句，表示“她评价学生的行动而不是听他们说的”。what的意思是“……的”。答案:c辨析1.fight for,fight
