徐华

徐华说，大部分学习者称，只要可以听见老师的声音、知识清晰易懂，他们其实是不需要看到老师的面孔的。所以，我们采用flash课件和音频结合的方式。

We use flash and voice recordings now as most of our learners said they dont need to see the teachers just as long as their voices are clear and easy to understand .

你好！我叫徐华。我是北京人。

徐华说，如果报名参加课程的人数足够多，小额收费或许可以起到帮助作用。

Xu said charging a small fee may work if there are enough people signing up for the classes .

举个例子，如果有一名学习者错过了一堂课，班长就会联系他，并且问清楚他为什么缺席了课堂、同时还会努力帮助他克服困难，这样就能保证学生的兴趣不减。徐华说道。

For example , if a learner misses a class , the class monitor will contact him to find out why and classmates will try to help others overcome difficulties so they all stay interested , Xu said .
