翻译:在过去的四周内,这里的小学生一直被使得每天忙于做各种各样的练习题.
1.短语“in the last/past + 一段时间”做句子时间状语时,意思是“在过去的一段时间内(截止到现在)”,要求句子必须采用现在完成时,排除AB;
2.句子主语pupils和keep之间明显是被动关系,即“小学生们是被使得做某事”的,排除采用主动结构的C,答案D为正解.
即:have kept (the pupils here) busy doing...
变成被动为:(the pupils here) have been kept busy doing.

学生们在最近四周每天都做各种各样的运动
首先in the last four weeks.与完成时连用
其次最近一直这样至于以后怎么样不知道所以要用进行时表示一种状态
希望能帮到你

在上四个星期里,这些小学生一直被持续做着各种的练习

应该用被动语态,所以选D
其他三个都不是被动语态
