Do you know why people yawn (打哈欠)? The most obvious answer is that we yawn because we are tired. But why does being tired make us yawn? How does yawning help us? The truth is that we don’t know the answers to these questions. Scientists have different theories about why we yawn, but nobody has been able to prove them.
The first one is the “oxygen theory”. In the past, one of the more popular theories was that we yawn in order to take more oxygen. When we yawn we breathe more deeply. According to this theory, our brains make us yawn because we need more oxygen. However, these days more and more scientists are against the oxygen theory.
The second one is the “brain cooling” theory. According to this theory, we yawn when our brains get too warm. Yawning makes our brains cooler again. When our brains are cooler, we can think more clearly. Yawning can help keep us alert (警觉). This theory hasn’t been proven yet, but many scientists think that it will be in the future.
Here are a few other interesting facts about yawning. First, yawning is contagious (可传染的). If you see another person yawn, then you will be more likely to yawn, too. Second, we yawn even before we are born. Studies have shown that babies yawn while they’re still in their mother’s stomach. They start to yawn after 24 weeks. Finally, we are more likely to yawn when we’re bored. Why is yawning contagious? Why do we yawn when we’re bored or tired? The truth is that we don’t have any answers to these questions, either.

I always have a dream to be a fluency speaker. Therefore, I am too shy to say a word in public. What is beyond my wildest imagination is fortune should bless me with a chance to realize my dream. One day, my English teacher asked me to go to her office and told us that I was given an opportunity to participate in an English speaking competition. Hear this, I could hardly hide my excitement. When making preparation for the competition, I write my speech carefully. I discussed it with my teacher and got many advice on how to improve it after I finished the composition. Under the help of my English teacher, I made a great progress.
