We'd like to remind readers that the responses to queries are usually best posted to the individual asking the question. That individual is then strongly encouraged to post a summary to the list. John read two hours. John read the book three times.
Any suggestions are welcome.
I will post a summary if there is enough interest. My second goal is to convince them that it doesn't have to be written to be a language. Dear linguists, I am interested in the research on the effect of conjunctions on the memory and reading comprehension of expository texts. I have read papers on this topic and found that previous researches produced quite controversial results. Their conclusions mainly fall into two categories,that is,conjunctions either have significant effects on reading comprehension and memory or they do not make any difference compared with the non-conjunction text version.
