我们不知道谁偷了课本.你觉得会是杰克吗?

我们不知道谁偷了那本书，有人认为是杰克干的，你怎么看

我错了..好像选2

选2，刚问老师的。
consider sb.to do
to have done已完成
sb consider doing sothing
你的问题是这样的吧：
We don;t know who stole the book . What;s your opinion?
Jack is considered ------it
我的团队都搞混了头

原题应该是这样吧：
We don't know who stole the book.What's your opinion ？Jack is considered_________it.
1.having done 2.to have done 3.doing 4.to do
答案选2，意思是我们都不知道是谁偷了那本书，有人认为是Jack干的，你怎么看？
