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”，因此谓语动词应用单数形式；句中的时间状语是in the last two years，说明是过去的情况，但本句表示过去的情况对现在造成的影响，因此应用现在完成进行时，故A)正确。
