阅读理解:Why Do We Yawn?
Do you ever open your mouth very wide and take a big breath in class? This is called a yawn. It is a very normal thing that humans and animals do. You might think it is just because you are bored, but there is a real scientific reason for it.
Think of your brain like a small computer in your head. When a computer works for a long time, it gets warm. Your brain also gets warm when you are tired or sleepy. When you yawn, you bring cool air into your mouth and nose. This cool air helps your brain temperature go down so it can work better.
So, a yawn is like a quick cooling fan for your head. It helps your brain feel fresh and ready to listen to the teacher. It is your body’s way of saying, "Wake up, brain!"

阅读理解:Useful Robots
Robots are more than toys — they help people every day! Some clean floors, some build cars in factories, and some even go to space! My school has a little robot that teaches coding. It moves, makes sounds, and follows commands. Robots use sensors and computers to "think". They don’t get tired, and they work very precisely. Scientists are making smarter robots that can learn new things. I think one day robots will help more in hospitals, schools, and homes. Robots may not have feelings, but they are very useful friends!
