问题 Many a specialist________ looking forward to attending that conference now and they plants in the last two years to prepare for it.

选项 A、is; have been studying
B、is; has been studying
C、are; have been studying
D、is; are studying

答案A

解析 本题考查主谓一致。many a意为“很多”,但它强调个体,即“每一个”,因此谓语动词应用第三人称单数形式。and后面的句子中的时间状语是in the last two years,说明句中谓语动词表示的动作发生在过去;结合句意可知,这一动作从两年前开始一直持续到现在,将来可能还会继续.因此第二个空格所在分句应用现在完成进行时,故A)正确。
