论文代写：NNEST和NEST
导师面临的最大劣势是学习者背景的多样性。由于学习者的优先级不同，NNEST的导师在对待他们时面临着挑战。例如，老师必须把阿拉伯语母语学习者和印度语学习者放在同一个班级。在这种情况下，不同的策略既能激发学习者的学习动机，又能使他们理解母语为英语的口语。因此，放松学习者的策略是根据学生的背景对导师进行分类。

当NNS教学时，学习者和老师都有相似的文化，语法规则很容易解释。因此，它增加了双方的优势。理解文章和激发语言学变得更容易和有效，因为教师可以与学生建立一个强大的融洽关系(Cakir和Demir, 2013)。另一种策略是让学生在同一个教室里学习，这样语法就可以教得更好、更有效，因为学习者在语言学习中有共同的困难。大声朗读来提高发音和处理托福考试的技巧，让学习体验变得有趣。
另一方面，NEST将文化问题作为社会实践的一部分来教授。它遵循一种真实的方法，但这种社会实践形式给学习者提供了在不同主题之间切换的灵活性。这是习语、短语动词和表达比其他非巢丰富的主要原因(Cakir和Demir, 2013)。我觉得无论是学习者还是导师，在学习策略和学习材料方面，都比NNEST更适应NEST的方法。

The biggest disadvantage faced by the mentors is the diverse backgrounds of learners. As the priorities differ among the learners, NNEST mentors have faced challenges in treating them. For instance, the teacher had to include native Arabic learner and an Indian in the same class. In such a case, the strategies differ to motivate both the learners and give them the understanding of native English speaking. As a result, the strategy followed to ease the learner is to categorize the mentors depending on the students’ backgrounds.

When taught by NNS, both learners and teachers share similar culture and the grammatical rules are easily explained. Hence, it adds advantage to both the ends. Comprehending passages and motivating linguistics become easier and effective as the teacher can establish a strong rapport with students (Cakir and Demir, 2013). The other strategy is having NNESTs in the same classroom so grammar can be taught better and effectively as learners have common difficulties in language learning. Reading loud to improve pronunciation and tips to handle TOEFL test make the learning experiences fun.
On the other hand, NEST teaches cultural issues as a part of social practice. It follows an authentic approach, but this form of social practice gives the learners the flexibility to switch between topics. This is the main reason for the richness in idioms, phrasal verbs and expressions than other non NESTs (Cakir and Demir, 2013). I feel that learners as well as mentors are very comfortable with NEST approach than NNEST in terms of learning strategies and materials involved.
