What is the best way to teach English reading comprehension to high school students?

There probably isn't any one best way because people are different in their ability to learn. One way would be to have the teacher read aloud a short page while the students follow in their books. Then the teacher should ask for questions or opinions, and find out where the problems are in the students' understanding. Explaining the meaning of words that students don't know, and discussing what the author meant are very important. Vocabulary lessons and tests are also a good idea because a poor vocabulary limits understanding.
