1.Sally____Beijing for Shanghai and_____there ever since.You

1个回答

  • 1.因为有ever since故要用完成时,因为有and连接两动词,故时态要一致,过去完成时是"过去的过去",此处用现在完成时即可

    2和3题你对答案错

    appreciate doing sth固定搭配,appreciate having done表示其动作在谓语动作之前

    working hard at his or her lesson是分词短语作状语,可将之去掉来看,不可能选C,因为这样句子就没谓语了

    each of作主语谓语单数
