谢谢，Haiyang。我已经弄出这部分了，用的方法跟你说的一样，谢谢。

I tried the corpus.byu.edu with the following syntax: [push] [n*] [pr*] [n*] and it produces something like "PUSHING TROLLEYS AROUND SUPERMARKETS". You need to use some specific word in at least one of these slots, otherwise, the corpus contains too much information and won't allow you to search.

正则我不熟练,因为我基本不用.可以问一下梁博,许博等.
