     There is no doubt that adults, and even highlyeducated adults, vary greatly in the speed and

efficiency of their reading.Some proceed very slowly throughout; others clash along too quickly

and then have to regress(退回)．Poor readers in particular may lack the ability to vary their

manner of reading according to the type of reading matter and to their intentions in reading it.

     A good reader can move at great speed through the text of a novel or similar light reading matter.

He may be able to skim a page, picking up a word or two here and there, and gain a general idea of

what the text is about without really reading it.In reading more difficult material, with the intention of

taking in the whole of it, he will proceed more slowly, but even then he will vary his pace, concentrating

on the key words and passages, perhaps rereading them several times, and pass more quickly over the

remainder.A less efficient reader tends to maintain the same speed whatever the material he reads.

Consequently, even light reading matter gives him little pleasure because he reads so slowly.But this

pace may be too fast for really difficult material.

     A type of reading which necessitates careful attention to detail is proofreading (校对), in which the

reader, in order to detect misprints in a sample print, has to notice not so much the meaning of what he

reads as the exact shape and order of letters and words in the text.This is extremely difficult for most

people since they are accustomed to overlooking such details.In fact, considerable practice is required

to practice this task efficiently and it can be done only by reading very slowly, and by paying less attention

to the general meaning of the text.
