Broadcast hosting course: How to distinguish flat tongue from upturned voice in Putonghua training? In fact, there is no difference between flat tongue and upturned tongue, that is, Z, C, S and zh, ch, sh. Candidates can distinguish flat tongue by common skills and special training such as words, tongue twisters, poems and articles. First, the skill of distinguishing flat tongue sounds 1, using the phonological relationship of Mandarin to distinguish. The phonological coordination law of Putonghua shows: (1) words with ua uai uang as vowel and zh ch sh as initial consonant, such as "grasping, beating, dragging, Zhuang, Chuang, Shuang, chuai and Chuang"; (2) For words with en as the vowel, except for words such as "How, Shen (poor), Cen, Sen", words with eng as the vowel, except for "Zeng" and a few numbers with "Zeng" as the sound side, the initials of other words are all behind the tip of the tongue. (3) For words with ou as the vowel, except for a few numbers such as "together", all the other initials are CH; (4) Among the words with un(uen) as vowel, only the initials of "Shun, Suction, Shun and Instant" are sh, and the initials of other words are S; (5) In words with ong as the vowel, the initial is only S, and there is no sh. 2. According to the phonetic function of pictophonetic characters, most Chinese characters are pictophonetic characters, and the pronunciations of several words beside the same sound can be inferred by using the known phonetic symbols. Most of the characters next to the following Chinese characters are jaw-dropping: Zhong, Zheng, Zheng, Zhu, Sheng, Chang, Zhang, Zhe, Shi, Shen, Zhi, Shi, Shou, Zhi, Zhou, Zhuo, Zhi, Zhan, Chui, Zhu, Ru, Zhi, Shao, Zhang, Zhi, Zhou. Most of the characters next to the following Chinese characters are flat words: Zong, Cai, Zi, Zuo, Cai, Zun, Zi, Si, Cao, Cang, Zha, Zi, Zeng and so on. Although there are exceptions to this method, we might as well try it, but we should be cautious when using it, and we should also pay attention to the accumulation of exceptions at ordinary times to avoid discrepancies. 3. Remember little, don't remember much. Among the commonly used words, there are more tongue sounds than flat sounds, especially those with zh as the initial consonant are about twice as many as those with Z as the initial consonant, so it is much easier to remember only those words with Z as the initial consonant. 4. In pictophonetic characters, D and T are read from the phonetic side, or although D and T are not read, most of the words related to their two initials on the phonetic side are staggering.

Tongue twister training "There is a sun in the sky": there is a stone in the sky, a tongue in the mouth and five fingers in the hand. Whether it is the scorching sun in the sky, the hard stone in the ground, the soft tongue in the mouth, the fingers in the hand, or the scorching sun, the hard stone, the soft tongue and the fingers, they are all practicing their tongues. There are temples in the mountains: there are temples in the mountains and cities outside the mountains, with thirty-three disciples and forty-four masters. Thirty-three disciples practiced calligraphy in the temple, and forty-four masters went to work in the city. Thirty-three disciples spent forty-four hours and forty-four masters walked thirty-three miles. I walked 33 miles, did 44 things and spent 44 hours writing 33 words. 3. Poetry Training "To Wang Lun" (Li Bai): Li Bai was about to walk by boat when he suddenly heard a song on the shore. Peach Blossom Pond is deeper in thousands of feet than in Wang Lun! "Lotus Heart" (Xi Murong) I am a blooming summer lotus. I hope you can see that my wind and frost have not eroded autumn rain, and the green season has left me. I am elegant, not worried or afraid. Now is my most beautiful moment, but I lock the door behind my fragrant smile. Who knew my lotus heart missed it? You are either too early or too late. 4. The article trains "Kiss of an Angel" [America] James? 6? 1 Moore University, I met a young man with a huge and ugly birthmark on his face. The purple birthmark extends from the corner of his left eye to his lips, as if someone scratched his face vertically. The handsome face is ferocious and scary because of the birthmark. However, the defects of appearance can't hide the young man's friendly, humorous and positive personality. Anyone who has dealt with him will like him involuntarily. He also often attends lectures. At first, the audience's expression was always surprised and scared, but by the time he finished, everyone was convinced and applauded. Whenever this happens, I secretly admire his courage. That birthmark must have made him feel deeply inferior. Not everyone can overcome such a serious psychological obstacle and speak freely in everyone's surprised eyes. After we became best friends, one day, I asked him a hidden question: "How did you deal with that birthmark?" What I mean by this is: how did you overcome the embarrassment and inferiority caused by that birthmark? I will never forget his answer. He said, "Deal with it? I've always been proud of it! When I was very young, my father told me,' Son, before you were born, I prayed to God to give me a special child, so God gave you a special gift and asked the angel to make a mark for you. The mark on your face is the mark of an angel's kiss. He did it so that I could find you in the crowd at once. "When I saw you sleeping in the nursery with other babies, I knew at once that you were mine!" He went on to say, "When I was a child, my father told me this story every chance, so I was convinced of my good luck. I even feel sorry for those children who don't have red' hickeys' on their faces. I think the stranger's surprise is out of jealousy. So I work harder, for fear of wasting the special gift given to me by God. When I grow up, I still don't think my father lied to me: everyone gets special talents from God, and every child is different from his parents. "
