回複：收到推薦信，但是教授拒絕修改，大家看看這最後一段能用嗎？

I think it is good enough.

In response to your RFE, you need to draft a good RFE response letter with all your supporting evidence and recommendation letters.

Withour proper supporting evidence, the words like "excellent, extraodinary, outstanding" will become empty and useless.

So now it is your turn to compose a good RFE response letter for yourself if you DIY.

Just for reference!!
