Perhaps (也许) playing in water is a good choice (选择) to make us cool down. Taking a cool bath or shower, or even washing toys in a pan of cool water can also make us feel good on a hot day. Besides (此外), we can read stories or paint in front of a fan.

Also, it's important for us to drink water. On hot days, we can lose 16 glasses of water in one day. Most of the time, we feel thirsty because we are already short of water. So don't wait for thirst before we start to drink. We should try to drink as much water as we lose every day.

The food we eat also makes a difference in how we feel in hot weather. Cold meals can cool down our bodies. Fruits and vegetables are also helpful to stay cool. So, plan a healthy menu (菜单) for a hot day!

The story began in 1948 when engineers Norman Joseph Woodland and Bernard Silver made the first barcode. 26 years later, supermarkets started using it. Before barcodes, supermarket workers needed to type prices (输入价格) by hand. They had to spend much time and often made mistakes.

a barcode

Today, stores around the world scan (扫描) barcodes more than 6 billion times every day!

These black-and-white pictures tell important information about the products (产品), such as how much they are, when they were made, where they come from and so on.

For store workers, barcodes are useful because they can tell what are in stock (有现货). For example, if a store has 100 chocolate bars and sells 20, the workers will know that there are 80 left thanks to barcodes. This saves workers hours of counting and makes sure there are no empty shelves.

But barcodes aren't just for supermarkets. They help in many places. For example, libraries use them to track (追踪) books and hospitals scan them to give patients the right medicine.

a QR code

Now we have even smarter codes called QR codes. They can store much more information. To see them, you need a mobile phone to scan! The future of QR codes looks even more exciting. Companies are working on "dynamic (动态的) QR codes" that can change their information at any time. Some new QR codes can even work without an Internet connection.

From their beginning in 1948 to today, barcodes show how a simple idea can make life easier. The smart codes save us time every day when we shop and they keep getting better. The next time you hear that "beep", remember—those little pictures are working hard for you!

Today is my birthday and I am having a great time at the zoo with my dad.

There are many lovely animals in the zoo, like monkeys, pandas and giraffes. I see some people feeding them with our food. I'm going to feed them, too. But my dad quickly stops me. "Jim, it is not right to feed them with our food." He says.

"Why shouldn't I do so?" I turn to my dad and ask him.

"Because it can make them sick when they are not getting the right food. For example, chocolate is children's favorite, but it is not good for many animals. So we should protect them and feed them with their own food. In fact, we can help the animals by not feeding them our food." He explains.

"Sorry, Dad. Now I know it is important to understand that animals need to eat right. I won't do that again because it is bad for them. And thank you for telling me that."

My dad smiles and says, "Good for you, Jim. I am so happy that you are learning to think about the result before you do something. We can help the animals by being responsible（负责任的） for their health. What's more, animals need to learn to find food themselves, instead of（而不是） waiting for someone to feed them. I think you should keep in mind that animals are our friends, and we should help them to live freely and naturally."

I am glad to have such a meaningful conversation with my dad, because he teaches me how to take care of animals.
