So much to do, so little time. So much infonnation, so little time to read it. In this age there is more information than ever before. There is not enough time to read everything wewant to read. However, you can consume more information in shorter time through speed-reading. This article will not makeyou read 3,000 words per minute, but it will show you how to increase your speed significantly. You will also learn the basictechniques of speed-reading, along with the dos and don' ts of speed-reading.
When you first learned to read, you would say the word out loud and sound it out. Then you might whisper the word because people can become annoyed when you read aloud. The stage you are now at is saying the word in your head. Most people tend to read this way. Saying the word in your head will cut your reading speed tremendously (极大地).
How do you calculate your reading speed? The speed is measured by how many words per minute you can read. Get some reading material, preferably a book. Find out how many words are on the page. Time yourself for one minute. Start your timer and start reading. When the timer beeps, stop. If you counted 500 words on the page and you read half of the page, and then you are probably reading at 250 words per minute.
The first thing about speed-reading is looking at the word and recognizing it. Don't say the word in your mind, just look at it and recognize its importance. Later you will recognize clumps of four words or more to increase your speed. This is the first and most important step in speed-reading.
The next step is technique. As with any other skill, speedreading requires technique. You should first be sitting up straight with your book flat on a horizontal (水平的) surface, such as a table or desk. Next,you should be able to see the entire page. This is necessary if you want to recognize clumps of words. Lastly, you should be focused. It' s hard to read with a lot of noise. Find a quiet place to read. This will help your understanding of the text.
You need something to guide your eyes while reading. That's right, you should use your hand. Remember when you were little, you would read using your finger. That is a great technique, only now you're using your hand to underline each line. Move your finger smoothly across the page. No need to go rush, start out slow. Keep your eyes focused on the words as you recognize them while using your hand as a guide. This will increase your'speed.
The third step is practice. Practice makes perfect. Set time intervals (间歇). Read using different techniques, but make sure you understand what you are reading.
