Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.

As your eyes move along the line of print, they make fixations(固定) or pauses. It is important that you see several words at a fixation. It is also important that your eyes leave a group of words quickly and move on to another group. The number of letters or words that you see at a fixation is called your eye span. Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.

The way in which you read always depends on what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method that is necessary. Here are four ways of reading:

(1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points.

(2) Rapid first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.

(3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive(精深的) study of your school subjects, solving maths problems or reading directions.

(4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing material that you already know well.
