The differences between various dialects and Putonghua are mainly manifested in phonetics, with little difference in vocabulary and grammar. Pronunciation differences mainly include: in most areas, there is no difference between flat tongue and tip of tongue, no difference between N and L, lack of vowels such as eng, ing, e and uo, no misuse of light tone and children's voice, and most people's vowels are not round. Combining these characteristics, students can find out the corresponding laws between dialects and Putonghua by themselves or under the guidance of professional teachers, and the effect of practicing and remembering more will double!
Second, always listen and practice, and practice again and again.
Listening is also called "listening" or "ear training". Good listening is the basis of learning Mandarin well, so listening more is an aspect that beginners should pay attention to. You can choose the programs of China People's Broadcasting Station and CCTV as listening materials. When watching TV, you should pay attention to the announcer's mouth shape, and you can imitate it while listening. You can also compare the recordings of standard Putonghua speakers with your own recordings to find out the differences. Improve it!
Third, say: when your listening is good, you should move more. Listening is the premise, and speaking is the key.
Speaking Mandarin well should be based on accurate pronunciation, so in the process of learning, students must pay attention to the learning steps, otherwise putting the cart before the horse will still make great efforts to correct the pronunciation mistakes.
