I have been learning English for seven months. I know the basic grammar rules of final /s/, for example, she like*s* ..., he love*s* ..., and so on.
In Thai language, we don't have /s/, /k/, /t/, and other sounds that flow the air out of the mouth.
My problem is during conversation. I usually forget to pronounce final /s/ and sometimes /s/ at the middle of the word. Even I read aloud to my teachers, I still drop those sound. I want to break this habit. I would like to know some good ideas to practice and retain final /s/ and /s/ at the middle of the word.
