【推荐1】At the age of 35, Johnson Barnes injured(损伤) himself when skating during a winter vacation. His doctors said he could never walk again. But a new technology(科技), the robotic exoskeleton(外骨骼机械装置), brought Johnson and other people like him a surprise —— it can work like our arms, legs or hands out side our body. Now Johnson can ask the machine to take him to the places he wants to go to and help him reach the things he wants to get.

Although the disable(残疾的) people still can’t do everything like a healthy man, the exoskeleton makes them believe they can do things by themselves and they will be better and better in the future. So they won’t see themselves as useless people and they don’t give up themselves. Most importantly, they will see the world with a loving heart and still play a part in making a difference to the world.

There are still some problems with exoskeleton, though. For example, they are not easy to use, and sometimes people with them fall down easily. What’s more, they are very expensive, costing about $100,000. It’s too much to a common family. But computers were also seemed impossible for a common family to use 40 years ago. We never know what will happen in the future.

【推荐3】Tammy’s body was shaking (发抖)! Today was her first trip to the dentist. She didn’t know what to expect. What would happen? Would it hurt? Would she shout?

Mom said it wasn’t scary at all, but Tammy didn’t know. How bad would it be? The dentist would clean her teeth. Then he would take pictures of her teeth to see if they were rotten (腐烂的).

That didn’t sound too bad. She cleaned her teeth at home already. She liked to smile. She wanted clean teeth and didn’t want rotten teeth. Pictures and cleaning sounded OK with her.

At the office, many people were waiting. There was a fish tank (鱼缸) to look at and magazines to read. She chose a magazine and found it interesting. She didn’t have to wait long, though. Soon it was her turn.

The dentist was a kind, old man. He smiled and Tammy sat in a special chair. There were lots of lights and tools (工具). It didn’t make her comfortable when she opened her mouth. He looked really closely. He cleaned her teeth carefully and then took pictures of her teeth. Then she was done.

【推荐1】Hundreds of years ago, life was much harder than it is today. People didn’t have modern(现代化的) machines. There was no modern medicine, either.

Life today has brought new problems. One of the biggest is pollution.

Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.

Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog(烟雾).

Many countries are making rules to fight pollution. Factories must now clean their water before it is poured and they mustn’t blow dirty smoke into the air.

We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.

Rules are not enough. Every person must help to fight pollution.
