Hey，show your teeth first!
If you talk to a man in a language he understands, that goes to his head. If you talk to him in his own language, that goes to his heart.
One language sets you in a corridor for life. Two languages open every door along the way.
The limits of my language are the limits of my world.
Learn everything you can, anytime you can, from anyone you can; there will always come a time when you will be grateful you did.
Learning is a treasure that will follow its owner everywhere.
You can never understand one language until you understand at least two.
To have another language is to possess a second soul.
JohanWn von Goethe
Those who know nothing of foreign languages know nothing of their own.
Rita Mae Brown
Language is the road map of a culture. It tells you where its people come from and where they are going.
Oliver Wendell Holmes
Language is the blood of the soul into which thoughts run and out of which they grow.
