     If you want to become a better reader, what should you know about speed of reading?

     Some people read very rapidly (很快地), while others read very slowly. But which one is better?

     The rapid reader may be a good reader when he reads a storybook for fun. But he may not be able to

slow down enough to read directions (说明) carefully. He may read so rapidly that he does not take time to

understand fully the ideas and information which are important to remember.

     The slow reader may be a good reader when he reads directions for making something. But he may

spend too much time in reading a simple story which is meant to be enjoyed but is not important enough to

be remembered.

     So, you see, either a rapid reader or a slow reader is not really a good one. If you wish to become a

better reader, here are four important things to remember about speed of reading.

     1. Knowing why you are reading 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,

science and history books, and Maths problems. You must read such things slowly or remember each

important step and understand each important idea.

     3. Some things should be read rapidly throughout. Examples are simple stories for enjoyment, letters

from friends and bits of news from hometown papers.

     4. In some of your reading, you must change your speed from fast to slow and slow to fast, as you go

along. You will need to read certain (某些) pages rapidly and then slow down and do more careful reading

when you come to important ideas.

1. What should be read rapidly?

A. Directions for making something.

B. Maths problems.

C. Science and history books.

D. Storybooks, newspapers, personal letters, etc.

2. What is the important thing you should keep in mind about speed of reading?

A. To read as fast as you can.

B. To fit your reading speed to your needs.

C. To read as slowly as possible.
