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 many a意为“很多"，但它强调个体，即“每一个”，因此谓语动词应用单数形式。句中的时间状语是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。
