It is generally agreed that a good student must be able to concentrate for a reasonable time on a written text, yet most students are given very little help to practice this skill. Almost all classroom reading is    into minutes of reading and therefore it is no wonder that a number of students have    in this field.

Be sure that you keep your    in mind during your reading so that you know you should also adopt some specific techniques—such as making notes from your reading—to aid your concentration.
If you play the role of a    receiver of information, simply concentrating on absorbing everything you read, you will    that your mind is overloaded, confused by the material. Then you should take a more active approach. Enter into a    with the text, pausing to reflect on what you read, and     what you find. That’ll be good for reading and comprehension.
