Little wonder-------up their hands in dismay A.have some thr

这个主要是否定词在句首是不是用倒装的问题.
这句话相当于
It is little wonder that some have thrown up their hands in dismay.
No wonder they will come.这个是不倒装的.
相当于
It is no wonder that they will come.在口语中是可以省略It is ...that的.
意思是
怪不得有些人沮丧地放弃努力了.
throw up one's hand放弃努力
