题型:单项选择题

Learning Chinese has been like climbing a steep(陡峭的)mountain.

My mother was born in Tokyo,while my father moved from Shanghai to Hong Kong when he was seven years old. At home we speak English. I know some basic Chinese customs :to use chosticks gracefully (得体地)and what to say on Spring Festival to get a red envelope. But I never truly learned to speak Chinese.

Why should I need to learn the language ,anyway? I live in America where everyone speaks English.

I realized I was wrong in ninth grade when I arrived at Philips Academy,a famous boarding school in Massachusetts.The school encourages a global outlook(视野). There I decided to welcome the opportunity to learn Chinese. I met other American-born Chinese and together we spoke Ching-lish outside of the classroom.

I searched for ways to access Chinese culture through dramas such as Meteor Garden (《流星花园》)and music by singers such as S.H.E,Wilbur Pan and Jasmine Leung(梁静茹). Listening to Chinese music is where I found my favorite singer in the whole world:Jay Chou. Even if I cannot understand what he is crooning(哼唱), I do feel more Chinese whenever I listen to his music.

Last summer I spent five weeks in China,four of which were taking a language course at a Beijing high school. I was proud when I could understand the dialogue in Intitial D(《头文字D》) and when I could easily translate Fairy Tale sung by Kong Leung(光良).

Learning Chinese has been a rocky trek(艰苦跋涉), and I know it will continue to be that way before I arrive at a relative plateau(高地) of fluency(流利).I hope that one day I will be able to work and maybe even live in China as a true Chinese.
