21、Reading is a good habit，but the problem is there’s too much to read these days，and too little time to read every word of it．There are hundreds of skills to help you read more in less time．Here are two skills（技能）that I think are very good．

Preview一if it’s long and hard．Previewing is very useful for getting a general（概括性的）idea of heavy reading like long magazine articles and science reports．

Here’s how to preview．

●Read the first two paragraphs and the last two paragraphs（段落）carefully．

●Then read only the first sentence of the other paragraphs．

Previewing doesn’t give you all the details．It tells you not to spend time on things you don’t really want-or need-to read．

Skim—if it’s short and simple．Skimming is a good way to get a general idea of light reading—like popular magazines or the sports of your daily paper．

Here’s how to skim．

●Get your eyes to move fast．Sweep them across each line．

●Pick up only a few key words in each line．

Everybody skims differently．You and I may not pick up the same words when we skim the same piece．but perhaps we’ll get the same idea of what it’s all about．
