Thank you two! I solved the problem by "cite" package.

I also tried the "mciteplus" package, I had a few error, I could not solve them, then I gave it up.

You have a great day!

I hope to make it "[1-3]" instead of "[1,2,3]"
the following is the Code:
\documentclass[12pt]{article}
\usepackage ...
