xuankuai You mentioned that you are running ArcGIS Pro 1.3.
My first recommendation is to upgrade to Pro 2.0.1 as there were things at 1.3 (notably annotation) that weren't supported. So it is possible that if there was something in the mxd that was not yet supported in Pro, it could cause the crash... conjecture at this point, but worth thinking about.
Please upgrade to 2.0.1 and try importing the mxd that crashes in Pro 1.3.
What happens?
Let us know, and if necessary, we can continue to help from there.
Thank you.
