So difficult __ it to work out the problem that I decided to ask Tom for advice.
B.did I find D.have I found
这个选b 请问是不是如果把d中的have 变成had ,d也对

不对,因为这是一个倒装句,里面did i find 是后句的描述,表示为
“这个问题这么困难以至于我解决不了,所以我去找的tom帮忙”
而如果使用了过去完成时作为倒装描述,就意为
“我终于发现这个问题很难了（不是抱着解决心态的意思）,于是我要去找tom帮忙”
那么,就忽略了句中主人在解题中的一些过程,而引申为主人并不是一个爱学习的孩子,只是看了一眼题目,就说“我发现这个题目很难了,找人帮忙吧”
因此,即使D语法对,意思也错了,而D语法也有问题,因此选B,改了也选B
这个回答你满意么,
