Comparison between Chinese learning and English learning of the Tibetan students is used to prove that foreign language teaching and learning is different from second language teaching and learning in this paper and the efficiency of foreign language teaching is lower than that of second language teaching because of the language environment.There is also difference between the amount and quality of the input of target language in the foreign language and second language classrooms caused by proficiency of teacher's target language.The key to improving the efficiency of foreign language teaching and learning is to make teachers' target language level better enough to match that of their thinking,language knowledge and teaching methodology and give more emphasis to pronunciation and grammatical rules at the learning beginning.
