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。
