I did some studying. <br />2. I did the studying I was supposed to do. <br />3. I did my studying. <br />4. I did studying. <br />5. I did homework <br /> <br />In [1], "studying" is being modified by the determiner "some" to indicate a quantity greater than zero. It's being used as a gerund (noun). <br /> <br />Similarly, in [2] and [3] "studying" is being treated as a noun. <br /> <br />But "studying" isn't a true noun. When it is the object of the verb "do", it needs determiners such as "some", "the" and "my" to identify it as a noun. Otherwise, its function becomes that of a verb. In [4], it is being used -- incorrectly -- as a verb. <br /> <br />"Homework", on the other hand, is a true noun, and therefore [5] is correct. <br /> <br />The correct past-tense form of this sentence is: <br /> <br />I studied last night. <br /> <br />If you wish to emphasize that you studied as opposed to doing something else, you can use the intensive form, which is the addition of "do" in an affirmative sentence: <br /> <br />I did study last night. <br />http://www.englishforums.com/English/DidIng/hbmr/post.htm#34884Mon, 28 Jun 2004 14:56:18 GMT946f00bb-57d3-4b7b-a9a2-059b5341af52:34884Fairy1http://www.englishforums.com/English/DidIng/hbmr/post.htm#34884http://www.englishforums.com/English/comments12-34884.xml<br /> <br /> <br />"i did study" <br />IS CORRECT:)http://www.englishforums.com/English/DidIng/hbjx/post.htmMon, 28 Jun 2004 01:02:26 GMT946f00bb-57d3-4b7b-a9a2-059b5341af52:34847Tania B2http://www.englishforums.com/English/DidIng/hbjx/post.htmhttp://www.englishforums.com/English/comments12-34847.xmlSomeone I work with asked me whether 'I did studying' is a correct sentence. Initially I told the person that is was incorrect. Then I tought about it and realized that it is common to say 'I did some studying'. For example, if someone says ' What did you do last night?' - 'I did a some studying, I did a bit of reading etc..' <br /> <br />Are both 'I did studying' and 'I did some studying' correct? If only the second one is correct, why is that? <br /> <br />Thank you.
