Have you ever noticed the black and white bars on a book？Do you know what they are used for?

They are bar-codes（条形码）used in most products. If you go to a supermarket，you can see almost every product with a bar-code on it. Bar-codes have information about the product, such as name and production date.It's an easy and convenient way to know about the products. Just scan the bar-code and everything is clear.

The first use of a bar-code in a supermarket checkout system was on a pack of American Wrigley Company chewing gum in 1974.Beyond supermarkets, bar-codes are needed everywhere:for renting cars, for luggage checks on a plane, for parcels(包裹) you send. Life would be rather difficult without bar-codes.Most of our things would get lost in the post.

Bar-codes change as well.Bar-codes in the past were 1-D(one-dimensional空间), but now there are 2-D bar-codes,such as QR code.Since 2009, QR has been used on Chinese train tickets. People can enter stadiums,cinemas and theaters by holding certain types of bar-codes.

With these small codes, life is getting much easier for us.

If you find these bar-code things boring, a bar-code building might be more up your street. In St Petersburg, Russia, there is a building designed like a bar-code.It looks strange, but it's actually a shopping mall. There are games too. Bar-code Monsters is a mobile phone game. You have to scan bar-codes and find the monsters!

Halfway through middle school, almost everyone has developed their own learning method. Yes, a recent conversation with my deskmate gave me a new thought on how to study wisely.

She was a typical procrastinator(拖拉的人) in our teachers’ eyes. However, I wonder how she tried to make gradual progress. Once, I asked her, “How do you improve your grades even without handing in homework on time?” She answered, “Handing in homework late doesn’t mean that I don’t study. I just review and learn first, then do my homework.”

So I suddenly realized that she wasn’t procrastinating, but taking her time to think. When reviewing, she was looking for her weakness and then strengthening them.

When we learn a new thing, we remember it best. Then we gradually forget it. A few days later, we may only be able to recall only a bit of it, or even nothing at all. Reviewing helps us better learn new knowledge. It helps us turn short-term memories into long-term memories.

On normal school days, when students don’t have to prepare for big exams, they should review their work and learn from their mistakes. Once it gets close to exams, it’s always wise to start preparing for them.

Therefore, we need to know how to study wisely. Otherwise, even if we spend a lot of time studying, there won’t be any improvement.
