the best example of universally understood body language may be the smile. a smile can help us get through difficult situations and find friends in a world of strangers. a smile can open doors and tear down (拆掉) walls.
i can still recall how nervous i was on my first day in the new school three years ago, when i felt it tough to follow my teacher in the first english class. the teacher spoke english throughout the class, which was totally different from the lessons i had taken before.
in the morning class the next day, the english teacher came to me while i was reading the text aloud as other students did. after listening to me for a while, she gave me a big smile and said she liked my voice very much. the smile shone on the whole day (照亮一整天)and the following days. a week later, i volunteered to take charge of (主动要求负责) english study in my class.
thanks to the comforting smile in my first morning class, without which i would never have become so confident. open your heart and smile more, our life is sure to be filled with happiness.
