Oral Putonghua teaching is the requirement of the times. Today, we have entered the information society. With the continuous development of science and technology, people should not only talk to people, but also deal with machines. A feature of modern production is high automation. An obvious sign of automation is that people use spoken language to command machines. With the rapid development of electronic technology and computing technology, machines can do many things instead of people. For example, in modern stations, docks, airports and large enterprises, traffic command and production management can be carried out through man-machine dialogue. In a few years, the machine translation of words will develop into the machine translation of spoken language. Enter Chinese here and other languages will come out there. The use of language typewriters will liberate human hands for the second time. The development of all these artificial intelligence indicates that the era of man-machine dialogue has begun. When people talk to machines, people are first required to speak standard Mandarin, and machines can only understand the language that meets the standard, because the language that people understand for machines during design must be the standard language. If you speak Shanghai Mandarin or Guangdong Mandarin with strong dialects, I'm sorry, but the machine can't serve you effectively. The machine's ears are not as smart as people's, and they can't understand Mandarin with a strong local accent, let alone dialects. Secondly, the machine's ability to understand and control the meaning of language is very poor, and the impurities in natural language cannot be ruled out. If you develop bad habits in your speech, such as stuttering, stuttering, incoherent preface, stopping where you shouldn't, and stopping where you should, it will be difficult for the machine to understand this kind of person's speech and it will be difficult for the machine to play its role. Therefore, the technical modernization of language transmission and man-machine dialogue must require everyone to speak standard Mandarin, and at the same time require everyone to express their thoughts and feelings in Mandarin in an orderly and appropriate manner. These are enough to show that spoken English is becoming more and more important. I didn't speak Mandarin before, and I didn't pay much attention to what I said. It doesn't seem to be a big deal, not now. Today, we are in a commodity economy society, vigorously developing the market economy and dealing with all kinds of people in society. Interpersonal relationship is much more complicated than before, which shows the importance of export language. We should negotiate with others, learn advanced things from others, introduce capital and technology, and express our views in public. If we can't speak Mandarin, or speak it badly, we can't communicate. Isn't that more important? Promoting Putonghua is indeed national unity; An important part of family prosperity. Improving the oral expression ability of Putonghua is not only a matter of speaking well, but also a matter of production development, technological development and economic and social benefits. For primary and secondary school students, this is another important measure for education to face the world. The improvement of the spoken language quality of the Han nationality is a sign that the Han nationality ranks among the nations in the world.
