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 that I think are especially good.
Preview--if it's long and hard. Previewing is especially useful for getting a general idea of heavy reading like long magazine articles and business reports.
Here's how to preview.
●Read the first two paragraphs and the last two paragraphs carefully.
●Then read only the first sentence of the other paragraphs.
Previewing doesn't give you all the details. It keeps you from spending 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 and entertainment 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 we'll get a similar idea of what it's all about.

Passage 3
A smile will tell people around you that you are a kind and friendly person. However, many people don’t smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn’t have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others’ teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them.
Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now.
