1. How often do you read books?
2. How often do you read a book?
3. How often do you read the book?
Are the three expressions all the same?
Would you let me know the differences among them?
The difference is #1 asks about books, plural. #2 uses "a" which is the indefinite, while #3 uses "the" which is the definite article.
The three expressions have slight differences in meaning:
1. "How often do you read books?" - This is a general question asking about your frequency of reading books in general. It implies that you read multiple books.
2. "How often do you read a book?" - This question asks about the frequency of reading a single book. It suggests that you are asking about how frequently a specific book is read.
3. "How often do you read the book?" - This question refers to a specific book that has been previously mentioned or is known to the speaker. It asks about the frequency of reading that particular book.
So, while the first two expressions have some overlap, the third expression is more specific and refers to a particular book.
