Yes, this is the question from the questionnaire in the research centre.http://www.englishforums.com/English/PresentPerfect/hnxbp/post.htm#652607Thu, 23 Apr 2009 19:10:33 GMT946f00bb-57d3-4b7b-a9a2-059b5341af52:652607Grammar Geek1http://www.englishforums.com/English/PresentPerfect/hnxbp/post.htm#652607http://www.englishforums.com/English/comments12-652607.xmlI agree with you, olga. I would expect &quot;How often do you consume alcohol?&quot; as the question as well. Perhaps something had changed - the person is in the hospital, and clearly is not drinking right now, so the doctor is asking about past habits up until the time of his admission?http://www.englishforums.com/English/PresentPerfect/hnxbp/post.htmMon, 23 Feb 2009 20:10:33 GMT946f00bb-57d3-4b7b-a9a2-059b5341af52:652594olga552http://www.englishforums.com/English/PresentPerfect/hnxbp/post.htmhttp://www.englishforums.com/English/comments12-652594.xmlHi! I have a question about Present Perfect Tense. I came across a sentence:&quot; How often have you consumed alcohol? &quot;Why is a Present Perfect here? We usually use a Present Simple , like “How often do you consume alcohol?” Thank you.
