He could've written a much better book if he had been working with me on it. I've learned all above sentences carry the same meaning. Am I right?

	Sarangadhar  +  452994 Fri, 14 Dec 07 01:27 AM I think only this is correct: He could've written a much better book if he had worked was working with me on it.   All the 3 given by you are wrong. Sarangadhar Joined on Wed, Nov 7 2007 New Member 48

Thanks. How about: if he worked with me on it. You can write like this: He would/could write a much better book if he worked with me. he will write a much better book if he works with me. but not "he could/would have written a much better book if he worked with me" Sarangadhar

	Liveinjapan  +  453006 Fri, 14 Dec 07 02:15 AM I know these rules, Sarangadhar. Thanks for your reply. Some native speakers of English told me: You can use past simple if it is obvious that you're mentioning the past. In conversations, the past simple is commonly used, in my opinion.

	CalifJim  +  453039 Fri, 14 Dec 07 04:22 AM I've learned all above sentences carry the same meaning. Am I right? Yes.  They are all understandable as having the same meaning.  However, only the last one is technically correct.
