But the apple was out of reach. He began to jump up and down, as high as he could, but he was still unable to _______ it. Soon, his energy (力量) ran out.

“I can’t _______!” he thought. “Maybe I can have something to stand on.” Looking around, he hoped he could find a rock, an old box, or, with luck, but there was nothing there.

_______ getting anything, he had to walk away. At first, he felt angry thinking about how hungry he became, and how he really wanted that apple. The _______ he thought like this, the unhappier he would become.

However, the boy was always a clever guy. After a while, he said to _______, “Being angry isn’t helpful. I can do nothing to get the apple, and I can’t change the result.

Eyes are important in our everyday life. We use them to read books, see colors and the beautiful things of the world. It’s of great importance to protect (保护) our eyes. But sometimes, we use them too much. That could hurt our eyes.

In the past, nearsightedness (近视) was a common eye problem for children. This is because of their bad eye habits. They watched TV too long and read books in bed. However, children these days spend more time studying and playing in front of electronic (电子) screens, such as computers, smartphones and iPads. This causes a new problem for their eyes: digital eyestrain (数字视疲劳). People with digital eyestrain may get headaches, dry and red eyes, eye pain, watering and other eye problems. But don’t worry. The following ways can help us protect our eyes properly. Try them out.

>Blink (眨眼) more often when you are looking at the screen. This can help to stop dry eyes.

>Remember the 20—20—20 rules: every 20 minutes, take a 20-second (秒) break and look at something 20 feet（about 6 meters）away.

>When using the computer, sit up straight in your chair and straighten your arms in front of you. Make sure your hands can’t reach the screen. And you need to look down at your screen.

>When you use the smart phone, keep it at least 30cm from your eyes. Try not to use your smartphone in sunlight.

Many kids do housework such as doing the dishes, making the bed, and folding the clothes. In return, they get some money or other computer time from their parents.

Paying kids for housework is one of the most popular topics, especially at a time when everyone is more careful about money. Some parents think we should pay kids for everyday housework because adults (成年人) are paid to do their jobs.

But some people don’t think kids should get rewards (报酬) for doing housework. Susie Walton, an expert, completely agrees. She believes that by rewarding kids, parents are sending a message that work isn't their job unless you get something in return. “Doing housework is a teamwork,” Walton said. “A home is a living space for everyone in the family. It’s important for kids to understand that everyone is fair in the house and we all have responsibilities (责任). Family members decide how they want their home to look, and how they are going to keep it clean and tidy.”

Other people believe that getting a reward encourages (鼓励) kids to do housework, and it also teaches them real world lessons about how we need to work to get money. There are also apps that give kids points and digital gifts that can be redeemed (兑现) either online or in the real world. “Our goal is to give kids lawful power so they can get rewards,” says Chris Bergman. “And kids need rewards to make them keep on doing housework.”

The moon was behind a cloud. And there weren’t many stars in the sky. It was a     55     night. I saw a light of fire in my neighbor’s kitchen. I thought he     56     a night meal. So I went back to my bed.

Soon there was a smell of burning (燃烧) in the air and I thought     57     was probably wrong. I jumped out of bed     58     and went out to make sure. I saw fire coming out of my neighbor’s kitchen. Then I shouted, “Fire! Fire!” But no one in the neighborhood heard my shouts for     59    .

I ran into my house, called the firemen and went back to my neighbor’s house. I knocked on the door hard and called out my neighbor’s name.     60    , there was no answer. Finally I rushed into the house and saved a cat and a dog.

I tried to pour water     61     the kitchen window but it didn’t work. It was a big fire. Luckily, the firemen arrived over ten minutes later and     62     the fire.

When my neighbor came back, he was sad for his kitchen, but he thanked me for calling the firemen and for saving his     63    . He wanted to give me some money but I did not accept it.

Weeks later, my neighbor invited me to see his new kitchen and we enjoyed a big meal there. It made me very     64    . The accident brought us closer together. After that, we became best neighbors.
