We come across this phrase 'a hard act to follow' now and again, especially when there are several people taking turns to speak at a conference.

For example, 'thank you, Mr. Chairman. I was mesmerized by Professor Powell's brilliant presentation. That was a hard act to follow, I must say. Of course I won't be so stupid as to try and repeat what Professor Powell said, in my own, less effective words. Instead, I will pick up a few points from his presentation and make an attempt to elaborate on them…'

Here, 'that was a hard act to follow' can be rendered as follows:

刚才鲍教授的发言太精彩了，我的发言充其量只能算是鼠尾续貂罢了。

原来是“狗尾续貂”，但好像不太好听，老鼠可爱一点。
