the book
Rekha is the subject.The verb is - is reading. The predicate is the verb plus everything after the verb = is reading a book
the preposition in that sentence is [in]
Reading that book gave me new insight into the subject.
The sentence "After reading the whole book the plot seemed a little thin" has a dangling modifier. It is unclear who is reading the book, as the subject is not explicitly stated, resulting in a lack of clarity in the sentence.
Yes, the sentence "She will have been reading the book when you get there" is grammatically correct. It describes an action that will be ongoing (reading the book) before another action (you getting there) in the future.
The subject-verb-direct object sentence pattern is a type of sentence structure where the subject performs the action of the verb on the direct object. For example, in the sentence "She (subject) read (verb) the book (direct object)," the subject "she" is performing the action of reading on the direct object "the book."
"She is a paragon of reading." is a sentence, yes. You will notice that it has a subject ("she") and a predicate ("is a paragon of reading")
It is a noun. The word "reading" here is a gerund acting as a compound subject with the gerund "talking."
I'm at the libary, reading a book.
The subject is "book" or "a book"
The verb here is reading the book. Since reading is the verb and it is action so it is a verb.
The simple subject in the sentence "This book I must have for my report" is "book." The word "this" functions as a demonstrative adjective modifying "book," but the core subject is simply "book," which indicates what the sentence is about.
