If you wish to become a better reader, here are four important points to remember about rate,
or speed, of reading:
1. Knowing why you are reading-what you are reading to find out-will often help you to
know whether to read rapidly or slowly.
2. Some things should be read slowly throughout. Examples are directions for making or doing something, arithmetic problems, science and history books, which are full of important information. You must read such things slowly to remember each important step and understand each important idea.
3. Some things should be read rapidly throughout. Examples are simple stories meant for en- joyment, news, letters from friends, items, or bits of news from local, or hometown, paper, tell-
ing what is happening to friends and neighbors.
4. In some of your readings, you must change your speed from fast to slow and then to fast, as you go along. You need to read certain pages rapidly and then slow down and do more careful readings when you come to important ideas which must be remembered.
