I prefer to read e-book. Because e-book is more convenient than book. For example, if I read "Steve Jobs Biography", I don't have to bring the book to anywhere. What I need to do is to take an ipad, so that I can read any books I like. What's more, e-book is cheaper. If I buy "Steve Jobs Biography" in a book store, I have to spend $35 while I just need to pay $9.9 on the ibook.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
By the way, "I prefer to read e-books because e-books are more convenient than books"
Can I also say "I prefer to read the e-book because the e-book are more convenient than the book"?
Avoid repetition by using a pronoun:
'I prefer to read e-books because they are more convenient than books.'
'I prefer to read an e-book because it is more convenient than a book.'
***** NOT A TEACHER *****
May I add my two cents' worth to the excellent answers that you have already received?
I should like to suggest a few tiny changes:
"For example, if I read Steve Jobs, I don't have to carry the book around with me everywhere. All I need is my iPad."
a. I believe that most guides suggest that we italicize (underline) book titles.
b. If, for some reason, you insist on quotation marks, may I remind you that Americans prefer the commas to be within the quotation marks: "For example, if I read "Steve Jobs," I don't ...."
c. I think that writing teachers advise us to be concise and not to insult the intelligence of our readers. I know nothing
(NO THING) about iPads, but I am sure that your other readers do. Therefore, to tell them that you can read any
books on your iPad may slightly offend your readers.
d. I realize that some languages do not pluralize their nouns. Instead of "I love e-books," they just say, "I love
e-book." I am confident that the more you hear and read English, the more you will understand the importance of
plural nouns in English.
HAVE A NICE DAY!
I thought you could only download them from the Internet. I didn't know you could buy an iBook at the store.
