If you want to be a better reader, what should you know about the speed of reading? Some people read very quickly and others read very slowly. But which one is better? The quick reader may be a good reader when he reads a storybook for fun. But he may not be able to slow down to read instructions(说明书) carefully. The slow reader may be a good reader. But he may spend too much time reading a story for fun. So the reader who reads everything quickly or the one who reads everything slowly isn't really a good reader. Knowing why you are reading or what you are reading can help you to know whether(是否)you need to read quickly or slowly. Some things should be read slowly. You must read these things slowly all the time to understand and remember everything important. Examples(例子)are instructions for making or doing something. Also, math books, science and even some storybooks are full of important information. However, some things should be read quickly. Examples are picture-books for enjoyment, letters from friends , and some quick news from newspapers.
In some of your reading, you must change your speed from fast to slow and slow to fast. You will need to read some pages quickly and then slow down and do more carefully reading when you come to important ideas. So, knowing when to change your reading speed is one important symbol of being a good reader.
