Books can fit almost every need, temper, or interest. Books can be read when you are in the mood; you don't need to do it all the time. Books are both more personal and more impersonal than professors. Books have an inner confidence which individuals seldom show; they rarely have to be on the defensive. Books can afford to be bold, and courageous, and explanatory; they don't have to be so careful of boards of trustees, colleagues, and community opinion. Books are infinitely diverse; they run the gamut of all human activities. Books can express every point of view; if you need a different point of view, you can read a different book. Reading is probably the most important skill you need for successful studies. You will have to read lengthy assignments in different subjects with varying degrees of detail and difficulty. If you read inaccurately, you will fail to understand some of the information and ideas you read. If you read slowly, you will have to spent too much time reading your assignments and the rest of your work may suffer.
Poor reading may be a problem for you, but it can be solved. Like other skills, your abilty to read English fast and accurately demands careful instruction and purposeful practice. You must keep practising on your own to improve your reading skills.
