The mobile phone is a useful invention. It helps us in our daily lives. We can talk with friends with phones. We can buy things with them. We can take lots of beautiful pictures with them, too. Many children think that mobile phones are cool. They like to have a mobile phone, so they can talk with friends at any time and any place. However, most of the children do not think about (考虑) the health problems of using mobile phones. Some scientists say that mobile phones give off radiation (辐射). The radiation may be bad for people’s health. A study says that the radiation of mobile phones can have a chance of getting some kinds of cancer (癌症). But other scientists say that they don’t find any links (关联) between mobile phones and cancers. Scientists say that people can protect themselves from mobile phone radiation. One way is to use a headset (耳机). Or people can make short phone calls.

We can search (搜索) on computers or phones to find them. Paper books are heavy. But e-books are not. However? reading e-books for a long time isn’t good for our eyes. And you can’t find e-books on every topic.

Hello. I am a dolphin, but I am not a real dolphin. I am a robot dolphin. My skin feels like a real dolphin’s skin. I can swim like a real dolphin. I am the size of real dolphin. I am 2. 5 m long and weigh 30 kg. I don’t need any food. I don’t get sick, either. I have batteries in my body and they give me energy (能量) to swim.

I come from a Chinese company. The company wants to use me to save real dolphins in aquariums (水族馆) . Living in the aquariums is not good for real dolphins’ health. I am different from real dolphins. I can live in the aquariums and never get tired. I can even play with people in water.
