First of all, the problem of read-only format is easy to handle. Your teacher can save your words as a new document and edit them.

Second, there is a change. In my experience, the word version is not a big problem, and it is probably a font problem.

For example, the font founder Song _GBK is used in your words, but this font is not installed on your teacher's computer, so the effect of this font will not be displayed on the teacher's computer, which will cause displacement.

For another example, "Italic _GB23 12" and "Italic" have the same display effect, but if you use "Italic _GB23 12" and there is only "Italic" on your teacher's computer, it will also cause the above results. .

So you can choose some commonly used fonts to avoid this problem.
