I found some weird word choices in my syntax book.<br/><br/>ex1) We have to read <b><u>which</u></b> books and some papers.<br/><br/> Here, I suppose, the word "which" is used to give an example that the sentence given below is erroneous.<br/><br/>-&gt; <b><u>Which</u></b> books do we have to read [NP[NP___] (and) [NP some papers]]? (NP = noun phrase)<br/><br/>I don't say that word(which) used is wrong because it is chosen to make the point.<br/><br/>What I'd like to know is....<br/><br/>1. Isn't a word 'certain' or 'some' more appropriate in the sentence? (in a normal context or whatever)<br/><br/>[We have to read certain(or some) books and some papers]<br/><br/>ex2)He believed the rumor that John bought <u><b>what</b></u>.<br/><br/> In the same way, I suppose, the word "what" is used to give an example that the sentence given below is erroneous.<br/><br/> -&gt; What did he believe [NP the rumor [S' that John bought [NP ___]]]? <br/><br/>2. Isn't a word 'something' is more apporopriate in the sentence?<br/><br/>[He believed the rumor that John bought something]<br/><br/>2 questions^^; (1,2)
