回复：收到推荐信，但是教授拒绝修改，大家看看这最后一段能用吗？

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!!
