        1. —How do you plan to travel to Beijing, Jack?
          —I haven’t made up my mind ________to go by plane or not.

          A.if B.whether C.when D.how

          B

          解析試題分析:句意:--杰克,你計劃怎樣去北京了嗎?--我還沒有決定是否乘飛機去北京。分析:考查賓語從句的用法,引導(dǎo)詞為是否之意if 或者whether,但是,在接動詞不定式的時候運用whether.故選 B
          考點:考查連詞的用法。
