Richards (2010, 2016) suggests that a language’s choice between the wh-movement option and the wh-in-situ option is made on the basis of language-specific prosodic properties that determine whether or not a prosodic wh-domain containing both the interrogative C and the whphrase can be established. A wh-domain in this sense roughly corresponds to a piece of prosodic structure in which these two key elements are separated by as few prosodic boundaries as possible, ideally zero. Prosodic boundaries demarcate structural units of the sentence, known as Minor or Intermediate Phrases (henceforth MiPs) that may trivially or nontrivially correspond to syntactic constituents (cf. Nespor and Vogel 1986, Selkirk 1986, 2011, Truckenbrodt 1995, Wagner 2005, among others). Richards proposes the following algorithm for constructing larger MiPs in wh-questions (see also Szendrői 2001, 2003):

当Wh-Word拒绝留在原地时

理查兹（Richards（2010，2016））提出，语言的Wh-movement选项和wh-in-situ选项之间的选择是基于特定于语言的韵律属性来确定的，韵律性wh域是否包含疑问句可以建立C和短语。从这个意义上说，wh域大致相当于一个韵律结构，其中这两个关键元素被尽可能少的韵律边界分隔开，理想情况下为零。韵律边界划定了句子的结构单元，称为次要或中级短语（以下简称MiPs），可能微不足道或不重要地对应于句法成分（参见Nespor和Vogel 1986，Selkirk 1986、2011，Truckenbrodt 1995，Wagner 2005等） 。
