问题 Researchers found that the plants were very old indeed, and______in these spots some 115,000 years ago.

选项 A、had probably last grown
B、were probably last grown
C、would have had last grown
D、be it last grown

答案 A

解析 时态题。主句谓语动词为found,从句表明约11.5万年前存在的古老植物是最终生长在这些地方的物种,具有过去的过去之意,应使用过去完成时,故选择A。B选项为被动语态,而11.5万年前人类尚未出现,被动不符合逻辑,故排除;C选项为would have done结构,通常表示对过去事情的假设,即“本来会做”,与题干中确实生长过含义相悖,故排除;D选项不仅与之后的grown形成被动关系,且开头为be动词原形,与空格之前表并列的and无法形成对等关系,故排除。
