Reading is a good habit. There are hundreds of skills to help you read much in a short time. Here are two skills that I think are especially good.
Preview(预览)---if it’s long and hard. Previewing is especially useful for getting a main idea of heavy reading like long articles and reports.
Here’s how to preview.
●Read the first two paragraphs(段落) and the last two paragraphs carefully.
●Then read only the first sentence(句子) of the other paragraphs.
Previewing doesn’t give you everything. It stops you from spending time on things you don’t really want or need to read.
Skim(略读)----if it’s short and simple. Skimming is a good way to get a main idea of light reading ---like news about popular sports and stars.
Here’s how to skim.
●Get your eyes to move fast. Look through each line.
●Pick up only a few important words in each line.
Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we’ll get the main idea of the news or article.
