If the sound is thick enough and the range is large, I suggest you read something passionate! For example, my motherland, my dear motherland.
If you have a soft voice, I suggest you read something delicate, such as To Oak, I would like to be a torrent.
Don't read prose in the exam, read poetry and climax, which can reflect the characteristics of your voice! Because the judges won't listen to you finish reading those poems! Reading prose or stories is not good at all! I took the exam! !
