The course I selected was

Welcome to Basic Spanish 1: Getting Started

Teacher ：Ana Gimeno

Come form ：Universitat Politècnicade València，西班牙語語言MOOC

After learned this course I know in spanish to give you a flavor of what the language is like we're going to start with these two the first one if we want to greet somebody what would we say we'd say Hola, which means hello . we'd say Adiós Adiós, if we want to say please the expression that we have to use is Por favor, which means thanks. People say Gracias and if somebody says thank you to you ,we would say De nada, de nada, your welcome.

It’s so fan of this, I well remember these word, if I meet a Spanish people, I well talk to her.
