问题描述：
Finally,Tom _____ where he put his text book.He was happy.
A.finds B.finds out C.found D.found out
Which one/ why?
答
D
首先这是过去式，排除A和B.
其次find是发现的意思，无找到的意思，后面直接跟宾语“发现什么”不能跟从句。而find out是找出的意思，后可跟从句
如：
They need to interview some people and find out if they like their jobs.
他们需要接见一些人并且查明是否他们喜欢他们的工作。
答
D. found out 查出 查明 核实 更具动词 看出应该是过去时 he put
was happy
答
d
过去式,可以排除a和b
find只是找的意思,根据上下文是要表达找到、找出的意思,因此用find out
