far below good Although i am working as an IBT speaking teacher,i do not think my english is good enough ,especially for some very hard questions in this test. I feel so desperate sometimes. but i think there's so reason to discard right? there is a Chinese saying : 教学相长（jiao xue xiang zhang）which means the teach can also learn someting when he is teaching the kids. I will hold on ↖(^ω^)↗

As An English-major student Everytime I told someone my major is Enlish, that guy may say,"wow, so your English must be cool! well, what the meaning of this word is?" then he will give me a HARD word such as a word in medicine or science. hey, i am not an stident whose major is dictionary XD

could u help me to correct my composition？ Social Practice in Education Recently,social practice has become more and more popular in the college students.I do believe there are some seasons for the phenomenon. Firstly,social practice gives us college students g good chance to experince the word outside of the school yard. In the social practice ,we can not depend on the book totally, we have to solve the problem based on the reality by ouselves. Secondly,social practice tells us the shortcoming we have to improve .Most of the time, we will chose the social practice related with our majors,so by this,we can use the things we learn from the calss.Absolutely,the progress of social practice will show us the things demanded by the society. Thirdly ,we can meet different people and learn lot from them. In the social practice, we will meet persons we like or dislike, we have to face many situations which need us to be flexible and smart. Of course, our boss and colleagues are good teachers in interpersonal relationship and professional working skills for us. These would benefit us in our future career. So ,I hold the view that the position of social practice in education is very important and it should be a part of the whole education.
