原句应该为：
I think (that)... trees were planted last spring.
I think (that)they planted.trees last spring.
就名词前的数量提问用how many；
do you think已经用了疑问句的形式,所以其后的从句不用再写成疑问语序,只要把疑问词提前即可,若想用主动形式答案B应改为they planted.
A,树是在过去被种,所以用过去被动式.
如果用B的话,应该改为：how many trees do you think they planted last spring.

收起
A,树是在过去被种，所以用过去被动式。
如果用B的话，应该改为：how many trees do you think they planted last spring.
首先 要分清楚这个句子的主语 是trees 是被种 属被动句式 要用被动语态 其次 do you think 只属于一个状语 可以前置 也可以后置 所以不必考虑它的位置。原句也可以改成 Do you think how many trees were planted last spring ?
本例句中，主语是trees树，所以用被动语态。选A
主语如果是人，比如students，就可以用B
首先这是一个从句，那么要用陈述句的顺序、从这点就可以判断B是错的，用了A是被动语态，去年春天有多少树被载？
