Unit 1 The Story of Steve Jobs This is the text of the Commencement Address by Steve Jobs, CEO of Apple Computer and of Pixar Animation Studios, at Stanford University, delivered on June 12, 2005. 1 I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I've ever gotten to a college graduation. I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out? 2 It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking, "We have an unexpected baby boy; do you want him?" They said, "Of course." My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college. This was the start in my life. 3 And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trusted that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes 本文是苹果计算机公司和皮克斯动画工作室的首席执行官史蒂夫?乔布斯 于2005年6月12日在斯坦福大学毕业典礼上的演讲稿。 1 今天，我很荣幸能来到这所世界顶尖大学参加你们的毕业典礼。我大学没有毕业。说实话，现在是我最接近大学毕业的时刻。我在里德学院读了6个月就退学了，但是作为旁听生又在那里待了18个月左右，然后才真正离开学校。那么我为什么要退学呢？ 2 这要从我还没有出生的时候说起。我的生母是个年轻未婚的研究生，因此她决定把我送给别人收养。她觉得我必须由有大学学历的人收养。于是，她安排好了一切，只要我一出生，就把我交给一位律师和他的妻子收养。但是我出生之后，他们在最后一刻决定他们还是想要一个女孩。当时我父母还在候补名单上，一天半夜他们接到一个电话，问他们：“有个新生儿，是意外怀上的，是个男孩，你们要吗？”他们回答：“当然要。”但是，我的生母随后发现我母亲大学没有毕业，我父亲甚至连高中也没毕业，因此拒绝在最后几份领养文件上签字。直到几个月后，我父母承诺将来一定让我上大学，她才同意了。这就是我生命的开始。 3 17年后，我确实上了大学。但是出于无知，我选了一所几乎与斯坦福一样昂贵的学校，因此，工薪阶层的父母把所有积蓄都花在了我的学费上。6个月过去了，我看不到其中的价值所在。我不知道我的人生定位，也不知道大学将如何帮我找到答案，而我正在这里耗尽父母一生的积蓄。所以我决定退学，并相信一切都会顺利。这在当时看来非常可怕，但现在回头

Unit1 Part 1谢谢您带给我们多年来最畅快的欢笑 1 最近一个周末，有位女士在大西洋城玩老虎机，赢了满满一桶二十五美分的硬币。她暂时离开赌博机，与丈夫前往旅馆餐厅吃晚饭。 2 不过，她想先去客房把硬币藏起来。“我去一会儿就回来，然后我们再去吃饭。”她对她的丈夫说道，之后，便提着满满一桶硬币朝电梯走去。 3 她正要走进电梯时，看到电梯里已经有两位男乘客。两位都是黑人，其中一位个头很高，体型令人望而生畏。这位女士一下子愣住了。她的第一反应是：“这两个男人会打劫我。”她转而又想：“不要戴着‘有色眼镜’看人；他们看上去完全像是绅士。”然而，种族偏见的力量是强大的，恐惧使她浑身发凉。她定在那里，眼睛紧盯着眼前两位男子。 4 她开始焦虑，心神不定，又感到不好意思。她希望他们没有看出她的心思，但是，天啊，他们肯定已经知道她在琢磨什么了！ 5 要不要进去和他们同乘一部电梯？她迟疑不决的态度已经太过明显了。她涨得满脸通红。老站着不动也无济于事，于是她横下心来，抬起一只脚往前挪，接着另一只脚也跟了进来，站在电梯内。她不敢抬眼，僵直地转过身，脸朝外，这时，电梯门合上了。时间一秒一秒地过去。她越来越害怕！电梯纹丝不动。她陷入了恐惧的深渊。“我的天啊，”她暗忖，“我被困在这里，要遭人劫财！”她的心往下沉，每个毛孔都在冒汗水。 6 这时，她听到其中一个人说：“趴下（与“按下楼层”同音）。”她的本能反应就是照着他们的话做。于是她张开双臂，趴在了电梯地板上，满桶的硬币飞向空中，洒了出去。硬币如雨点般落在了她的身上。她在心里默祷：“把钱拿去吧，饶我一命。”又过了几秒钟，她听到其中一位男子彬彬有礼地说：“夫人，您只要告诉我您要去几楼，我们来按按钮。”说这话的人有点费力才把话说完，尽力忍住没有放声大笑。 7 这位女士抬起头望着这两位男乘客。他们弯下腰，把她搀扶起来。她满腹疑惑，挣扎着站了起来。“我叫我这个朋友按楼层，”那位普通个头的男子说，“意思是叫他按我们要去的楼层的按钮。夫人，我并非要您趴在地上。”他说话时态度和蔼，紧咬着嘴唇。 8 很显然，他在极力忍住不笑出来。该女士心想：“我的天啊，真是丢人现眼，出大洋相了！”她羞愧难当，默不做声。她想要道一声歉，却不知如何开口。把两位绝对体面正派的绅士看作劫匪，如何请求他们的谅解？她不知该怎么说。他们三人拾起散落的硬币，重新放进了桶里。 9 电梯在她要去的楼层停下了，两位男士坚持要陪她到她的客房，因为她的脚步似乎有点摇晃，他们担心她在过道里会有闪失。他们将她送到门口，然后道了晚安。她迅速进入客房，耳边传来他们走回电梯时发出的哈哈大笑。她掸了掸灰，定了定神，便来到楼下与丈夫一起用餐。 10 第二天早晨，鲜花送到了她的客房——是12朵玫瑰，每一朵玫瑰都附上了一张崭新的百元美钞。 11 卡片上写着：“谢谢您带给我们多年来最畅快的欢笑。” 12 落款是： 艾迪?墨菲 迈克尔?乔丹 Keys to exercises: 6.

英语翻译专项习题及答案解析含解析 一、高中英语翻译 1．高中英语翻译题：Directions：Translate the following sentences into English, using the words given in the brackets. 1．晚上别喝太多的咖啡，会睡不着觉的。（or） 2．事实证明，保持快乐的心态会降低得心脏病的风险。（It） 3．乐观的人不会过分怀念美好的旧时光，因为他们正忙着创造新的回忆。（create）4．追求稳定并不是什么坏事，很多时候这样的态度在促使我们提升自我、挑战难度、攀登高峰。（when） 【答案】 1．Don’t drink too much coffee at night, or you won’t be able to sleep. 2． It is proved that keeping a happy mind reduces the risk of heart diseases. 3．Optimistic people don’t miss the good old days too much, because they are busy creating new memories. 4． The pursuit of stability is not a bad thing. (and) There are many times when such an attitude drives us to improve ourselves, challenge difficulties, and climb peaks. 【解析】 【分析】 本题考查翻译，用括号所给的词将中文翻译成英文。翻译要注意句子的时态和语法的运用。 1．考查祈使句。祈使句 + and/or，前面的祈使句表示条件，or或and引导的分句表示结果这里表示转折关系，故用or。故答案为Don’t drink too much coffee at night, or you won’t be able to sleep. 2．考查名词性从句。翻译时句中用it作形式主语，真正的主语为从句thatkeeping a happy mind reduces the risk of heart diseases.，从句翻译时要注意动名词作主语。故答案为It is proved that keeping a happy mind reduces the risk of heart diseases. 3．考查动词。翻译时注意短语be busy doing忙于做……，时态用一般现在时。故答案为Optimistic people don’t miss the good old days too much, because they are busy creating new memories. 4．考查定语从句。先行词为times，在定语从句中作时间状语，故用关系副词when引导。故答案为The pursuit of stability is not a bad thing. (and) There are many times when such an attitude drives us to improve ourselves, challenge difficulties, and climb peaks. 2．高中英语翻译题：Translate the following sentences into English, using the words given in the brackets. 1．即使天气再热，也不要整天待在空调房间里。(stay) 2．一旦一个人学会了换位思考，就表明他正在走向成熟。(indicate) 3．直到他听了那个讲座才意识到自己对于该领域的知识是如此的匮乏。(It)
