1 Harm in your hand 手机蓝光对眼睛的伤害有多大？ The blue light that comes from our smartphones can give people a disease that may lead to blindness (失明), according to scientists from the University of Toledo in the US. When people use phones in the dark, more blue light goes into our eyes. 2 Sunscreen machine 这个机器可以帮你涂抹防晒霜。 Usually, it takes time to put sunscreen all over your body. But SnappyScreen from the US can help with this. It is a booth (小亭子) with nozzles (喷嘴). People stand inside the booth. The nozzles spray (喷射) your whole body with sunscreen in seconds. 3 The power of music 学习音乐有助于提高语言能力。 Learning music can improve children’s language skills, according to scientists from MIT.
