问答题Translate the underlined sentences in the following passage into Chinese. Remember to write the answers on the answer sheet A few years ago, I took a sightseeing trip to Washington DC. I saw many of our nation"s treasures, and I also saw a lot of our fellow citizens on the street-unfortunate ones, like panhandlers and homeless folks. I turned around, I saw an elderly blind woman with her hand extended. 6 In a reflex action, I reached into my pocket, pulled out all of my loose change and placed it in her hand without even looking at her. I was annoyed at being bothered by a beggar. The blind woman smiled and said, "I don"t want your money. I just need help finding the post office." In an instant, I realized what I had done. 7 I had acted with prejudice-I judged another person simply for what I assumed she had to be. I hated what I saw in myself. This incident re-awakened my core belief. It reaffirmed that I believe in humility, even though I"d lost it for a moment. The thing I had forgotten about myself is that I am an immigrant. I left Honduras and arrived in the US at the age of 15. I started my new life with two suitcases, my brother and sister, and a strong, no-nonsense mother. Through the years, I have been a dishwasher, roofer, cashier, mechanic, pizza delivery driver and many other humble jobs, and eventually I became a network engineer. In my own life, I have experienced many open acts of prejudice. I remember the time, when I was 17 and working as a busboy, 8 I heard a father tell his little boy that if he did not do well in school, he would end up like me. 9 I have also witnessed the same behavior to my family and friends, so I know what it"s like, and I should have known better. 10 But now, living in my American middle-class lifestyle, it is too easy to forget my past, to forget who I am and where I have been, and to lose sight of where I want to be going. That blind woman on the streets of Washington DC, cured me of my self-induced blindness. She reminded me of my belief in humility and to always keep my eyes and heart open. By the way, I helped that lady find the post office, and in writing this essay, I hope to thank her for a priceless lesson.

问答题 1 I was hesitant to write this article the way I have because I know some people may misinterpret my intentions, so I will clarify them before we begin so there is no misunderstanding. 2 My reason for writing about parts of my professional journey is not to impress you, but to impress upon you how possible it is for us to create "amazing" if we consider, apply, and embrace Certain principles. I don"t think I"m amazing and I don"t consider myself to be particularly gifted, but I do know that if I"m prepared to deal with some regular discomfort (hurdles, speed humps, setbacks, problems, challenges, and failures), then I drastically increase my chances of succeeding. 3 The more prepared I am to make mistakes, fall over and fail, the more likely I am to create long term success if I learn from my mistakes and adapt, grow, and change. Failure is merely a label people give certain events. I personally don"t use the term, but I will for the purpose of this conversation. When I set up my first commercial business I was 26 years old. I had no real idea what I was doing. I thought I did but looking back, I didn"t. I knew I wanted to set up a commercial Personal Training centre. 4 There were none in Australia, so I had no blueprint to follow, no mentors to rely on, and a whole bunch of people who informed me that the concept wouldn"t work in this country. In my mind I had a picture of what I wanted to create (the end result). It was just all the in-between steps that I was a little grey on--a lot grey on. 5 I had no idea about commercial leasing (租赁) or how to communicate or negotiate with real estate people. I had no experience running a business or employing or managing staff. I had limited leadership experience. I had no experience dealing or negotiating with equipment suppliers. I had no idea about business plans. I had no marketing skills and no idea what "branding" was.
