Нужно Read books сделать вопросительным предложение в простом настоящем времени.

Present Simple:

Do you read books? 
I don’t read books.
Past Simple:
I read books.(Глагол неправильный, поэтому он читается как "рэд")
I didn’t read books(Здесь уже глагол в первой форми и читается "рид", потому что вторая форма ушла в диднт)
Did you read books?(Здесь тоже самое, как и в отрицании)
Future Simple:
I’ll read books.
I won’t read books.
Will you read books?

В простом вопросительном предложении на первое место ставится Do или Does, на втором месте по подлежащее и потом смысловой глагол (сказуемое). Если есть наречия ( How often, What, Where) то они ставятся перед Do. Т. Е. Do you read books? Does she read books?
