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。
