In the hot summer vacation, I attended a small training class for commentators in zhejiang museum of natural history, and I became addicted to being a commentator.

I'm talking about the dinosaur scene. Let's take notes carefully in class first, collect information about these dinosaurs from the Internet, then organize and write our own explanation draft, and then read it several times and keep it in mind. I can't help thinking: it's so complicated to write explanations, but also to memorize them in Mandarin. It is not easy to be a good commentator!

In class, the teacher took us to practice Mandarin, recited tongue twisters and simulated explanations for teachers and classmates.

Finally, I'm going to the scene to explain to the visitors. At first I was nervous and my voice trembled a little. I accidentally forgot where I said it. What a mess. Slowly, with the encouragement of teachers and audience, I relaxed and became more and more courageous, explaining fluently and louder every time.

I got seven messages from the audience, passed the commentator's exam and got the red certificate. It is not easy! Next time I can be a dinosaur commentator in the Natural History Museum! I still have to learn the introduction of every scene. Welcome to listen to my explanation and give me valuable advice.
