师资水平的好坏可能直接影响最终的学习效果。推荐外教一对一是学习最佳途径。因为可以保证英语发音的纯正地道。更重要的是可以学习到外国人的逻辑思维，通过不断英语对话中增强语感。在选择时还要考虑到该外教是否拥有EFL或TESOL等证书，因为比较国际化，认知程度也比较高。
The quality of teachers may directly affect the final learning effect. One to one is the best way to learn. Because it can guarantee the authentic pronunciation of English. What's more, we can learn the logical thinking of foreigners and enhance the sense of language through continuous English conversation. In the selection, it is also necessary to consider whether the foreign teacher has the certificate of EFL or TESOL, because it is more international and has a higher cognitive level.
