        1. --Have you been to Beijing?
          --          .It’s a beautiful city.
          A.Yes,I do            B.Yes,I have          C.No,I haven’t
          B

          試題分析:句意:你曾經(jīng)去過北京嗎?去過,它是一個美麗的城市。have been to 曾經(jīng)去過某地,have是助動詞,可以提前,可以直接加not,F(xiàn)在完成時的構(gòu)成是:主語+have/has+動詞的過去分詞。聯(lián)系下句It’s a beautiful city.可知,作者應(yīng)是去過才知道它是一個美麗的城市,故選B。
