Hello, my friend, I have the following suggestions for you to practice Mandarin in the broadcasting host major: First, broadcasting host is the most important and basic one. Practice tongue twisters at ordinary times and pay attention to various pronunciation essentials. Even if you strive for it in your daily life, you should be able to communicate with people in Mandarin. Language environment is an important factor in learning Mandarin. Second, pay attention to the vocal music training methods taught by the teacher, practice frequently every day, pay attention to more breath, and speak with breath, so that your voice will not be overtired, and it will make your voice more mellow and beautiful. Third, pay more attention to social current affairs, and you can find some topic comments to make your teachers or classmates become your audience. This is the basic way to improve language fluency and hosting ability. Fourth, listening, reading and practicing more is the only way to practice Putonghua. Listen, you can listen to the online recitation of Putonghua works. Read, you can read words and tongue twisters according to your pronunciation defects. Practice, talk to people with relatively standard Mandarin or practice broadcasting news. 5. Watch the news broadcast every day while watching it. News broadcast is a very important link in broadcast hosting. It is of great benefit to your language fluency and your ability to broadcast and read manuscripts. You must believe that no pains, no gains. If you are satisfied, please accept it. Thank you.
