Who knows the pronunciation position of the flat tongue in Mandarin? ......

Flat tongue sound refers to the Z, C and S produced when the tongue is horizontally extended, close to or close to the back of the upper teeth; Tongue warping refers to zh, ch, sh, R produced when the tip of the tongue is tilted, touching or approaching the anterior hard palate. Among them, Z-ZH, C-CH and S-SH are really easy to be confused. The distinction should start from two aspects: first, correctly distinguish the pronunciation of flat tone and upturned tone (please refer to how to distinguish the initial consonants with confused pronunciation); The second is to recognize, remember and master words with flat tongue sound and sticky tongue sound as initials. Common methods are as follows:

(1) stands for part-of-speech ratio.

Most Chinese characters are pictophonetic characters. Most pictophonetic characters beside homophones have the same initials. Such as "age, Zeng, Zong, Zi, Cai, Cang, Cao, Cong, San, Si. Characters with "Lao" and "Sui" as radicals are mostly flat-tongued characters; Zhan, zhong, Zhu, zhuan, Chao, Cheng, Chu, Shao, Shan, Shen and Sheng are radical words, most of which are amazing. Therefore, by memorizing some representative words or radicals of flat tones, a large number of flat tones can be easily determined by analogy.

(2) Analogy of the phonetic rules of Putonghua.

In Mandarin, the combination of initials and finals is regular. For example, three vowels ua, uai and uang can be spelled with the tongue sounds zh, ch and sh, but not with the flat tongue sounds Z, C and S ... So when you come across words whose vowels are ua, uai and uang respectively, you can directly conclude that they are tongue-spitting. Another example is that the vowel ong can be spelled with the flat tongue sound S, but not with the tongue sound sh, so we can conclude that this vowel is "Song Song Song" of ong, and it will never be a tongue sound. Remembering these rules also helps us to distinguish and remember flat and warped words.

(3) Remember less and decide more.

In Putonghua, there are fewer lower tongue sounds and more tongue sounds. Some syllables in Xinhua Dictionary (rearranged edition) are quite special. For example, in ca, only four words are listed, such as "demolition" (dialect pronunciation c 1), "wipe" and "tea", while under the syllable cha, there are Chinese characters "fork, tea and tea". There are only two Chinese characters "how, how" under the Zen syllable, while there are Chinese characters "truth, pillow and town" under the true syllable; Especially under the Sen syllable, there is only one word "Sen", while under the Shen syllable, there are Chinese characters such as "Body, Spirit, Caution and Strictness". Similar to the above situation, we only need to remember a few flat-tongued words, and we can determine most of the warped words.
