When reading a piece of text, whether it is a story, an article or an instruction, it is very important that you understand, or comprehend, exactly what the writer means. We call this comprehension and it means understanding or comprehending the meaning of all the parts of a piece of writing.
One way of being able to be good in reading comprehension is to read the passage fully to really understand what the writer is intending. It is like reading a book. You can’t read a book for the first few pages and decide what the book is all about. You will need to read the entire book to really understand what the book was about. Otherwise, you will miss the suspense and if it is a murder mystery you will not know who the killer was! This also applies when reading facts. Take for example a train time table. If you don’t study the entire information on your proposed journey you would not be able to tell your friends or relatives your travel plans.
