请问这个如何翻译啊?

The Hawthorne experiments had another surprise in store.
in store是什么意思啊????

An awareness that they were being experimented upon seemed to be enough to alter workers' behavior by itself.
请问这个里面的upon是怎么回事.在这是什么成分,还谁联系的?

介词吧

being experimented upon sth(在这个句子是an awareness) ： 在。。身上试验过sth； 经历过sth

上句也可以说： They were being experiented upon an awareness which seemed to be enough to alter workers' behavior by itself

1. Hawthorne 实验还有另一个使人吃惊的（东西， 结果，等等) in store 含有， 藏有, 2. upon 的逻辑宾语是 they， experiment upon them = they were being experimented upon 意识到他们自己是实验对象这一点似乎足以改变工人的行为。

in store 表示 贮藏着，即将到来等意思，代入原句也就很好理解了。 upon相当于on，和前面的experiment（动词用） 连用表示对……作实验的意思，代入原句更加清楚。upon后接的宾语为：an awareness。
