        1. So far, the moon ________ by man already.  

          A.is visited B.will be visited C.has been visited D.was visited

          C

          解析試題分析:句意:到目前為止,人類已經(jīng)登上了月球。So far 引導(dǎo)的句型,一般用現(xiàn)在完成時(shí),本句也是被動(dòng)語(yǔ)態(tài)。故選C。
          考點(diǎn):考查時(shí)態(tài)和語(yǔ)態(tài)。
