it ______that pleasant music keeps people from becoming tired at their work.
1.has been found
2.is found
为什么是1不是2

It has been found that pleasant music keeps people from becoming tired at their work.[人们已经发现悦人的音乐会使人在工作中避免疲劳.]
本题应该根据句意理解吧,其中,“has been found”是被动语态的现在完成时结构,表示过去就被发现,而强调过去的发现对现在还有影响.比较符合题意.[现在完成时主要强调过去发生的动作对现在的影响或结果.]
而“is found”是被动语态的一般现在时结构,表示经常性或目前的动作或状态,相比之下较不合理.
但我觉得这种句子还应根据上下文才好作出判断.
