当一个人学英语遇到难关的时候,一定要乐观的挺过去,
当你成功时会发现过去的牢骚根本就没必要啊.
When you find it's hard for you to continue during your English study,
you have got to get it over in an optimistic manner,
then when you look back to these days after you succeed some day in future,
you will realize current complaints are all nothing.
