First notebook entry: Introducing myself Hello,everyone! My name is Yu , and you can also call me fish. Now I am a junior and it has been a long time since I spent my time on English study.In other words,my English is becoming poorer and poorer.Besides,maybe I will take the TOFEL test in the next two years. Hence，what I urgently need now is just an opportunity to extensively expose to the English environment and a learning platform.
