After six months of living in New Zealand, I realized one thing. Despite my 36 for greater contact with local students, 37 I initiated(开始) the contact, it wouldn’t happen. Local students are not interested in contacts with the international students, because they regard us as shy, 38 and sometimes snobby （势利的） people. Of course we know that’s not true. I want to change their opinions. After 39 the problem, I put on my “confidence mask” each morning and walked around with a smile on my face. I chatted with people whenever I had the chance. I showed that I was not afraid to 40 them, and that I was worthy of being a friend. A side-effect of my 41 confidence was that my emotions occasionally broke down Only in the 42 of my room, where no one could see, would I reveal my real emotions. All the rejections, funny looks, and 43 behind my back calling me a weirdo（古怪的人） melted into tears. Once that was done, I would put on my confidence mask once again and start a new day. It finally worked My name became known throughout the school as I appeared to be 44 and active. Slowly, I discovered that I no longer needed to put on my confidence mask. I had real friends. Instead of dragging myself to school and 45 to be happy, I was truly happy. I could not believe it when I was elected to the student government as Deputy Head boy----the first international student to receive the title. From my 46 in New Zealand, I believe one thing will always be true: If you try your best to reach your goals, you’ll achieve your 47 dreams.
