Without doubt, many Chinese sports fans sat in front of the TV and cheered our athletes on, hoping that they would get as many gold medals as possible. But sometimes our desire for gold medals can result in the sadness of failure. When Liu Xiang, China’s track hero, pulled out of the Beijing Olympics due to injury, he greatly disappointed many Chinese sports fans. But things are different now. In the 2020 Rio Olympic Games, we saw a healthier and more lenient Chinese attitude toward the sportspeople, fully in line with the Olympic spirit. China didn’t win any gold medals on the first day. But, instead of criticizing the athletes who failed to finish on top of the podium(領(lǐng)獎(jiǎng)臺(tái) ), the majority of fans were happy with their efforts. “Reacting in the right way when an athlete misses out on gold shows the maturity of a person, and is also a challenge for a country to face up to in the process of development,” mented CRI.

A great many researchers have made efforts to help foreign language learners to improve the approaches. Charles LeBeau is a public speaking professor and consultant. Currently, he teaches at two universities and at the Toshiba International Training Center. He has also written books on the subject. English language learners around the world use his book Speaking of Speech. In Speaking of Speech Mr. LeBeau says a simple approach helps the learners. So, the professor divides public speaking into three parts: the physical message, the visual message, and the story message. He says, “The central thing to remember about public speaking or presentation is that it’s a very plex municative activity. For nonnative speakers it’s a really scary activity. So to make that more simplistic and easy for them, the approach that I’ve taken is to simplify and break it down. First if we look at presentation, what’s going on? There are basically three messages that the presenter is giving the audience at the same time. There’s what I call the physical message, namely body language. It’s the way that my body, as a speaker, is talking to the audience. Then there’s also the visual message. The visual messages are the slides that we now make and show the audience. The third message is the story message, which is the content of our presentation. The story message is the verbal message, what we say to the audience. The story message also includes how we anize our ideas to present to the audience.” He says the simple approach to breaking down the parts of public speaking has proved itself. He says learners improve quickly and do a good presentation after a few days of study. 29. What does Mr. LeBeau think of public speaking? A. Public speaking is a simple task. B.
