课文翻译 我的大学生活 我和我的毕业同学们一直在等待着我走上舞台领取学位证书的那一刻。我感到高兴和宽慰，但对未来感到担忧和焦虑。我的第一份工作会是什么样的？这次短暂的步行将使我投入一个全新的世界。我该怎么办？我能为自己开创一份事业吗？有人叫我的名字，我走到灯光下。我听到了掌声。我知道我的父母会互相注视和微笑，我试着放松。我把证书放在胸前，对着摄像机微笑。在我意识到这一点之前，典礼已经结束，我的大学生活也已经落幕。时间到哪里去了？四年一晃就过去了。我手里拿着证书，站在那里回想那四年。 Unit 4　Never too old to learn 英语　选择性必修　第四册　Y 返回导航 课文翻译 我记得来到大学的第一天，我在校门口停下，望着长长的车道。我能感觉到我的手在微微出汗，我不得不紧紧抓住我的手提箱。我能适应吗？我生活的这个新阶段是否意味着我已经足够成熟，可以对自己的成功和失败负全部责任？我花了几秒钟的时间让自己镇定下来，并观察了一番眼前的情形。校园里挤满了人。焦急的家长和兴奋的学生们在小群体里交谈，提着手提箱，或者在宿舍楼里进进出出。我不知道上学的第一天是否总是这样热闹。我深吸了一口气，继续走进校园的中心地带。 我几乎没想到我就要经历我一生中最美好的四年时光。 Unit 4　Never too old to learn 英语　选择性必修　第四册　Y 返回导航 课文翻译 我记得我第一次做作业。它是一篇关于几何学的3 000字的文章，我真的不知道如何开始第一段。我没有寻求好的建议，而是一直拖延。我很不明智地把它留到了最后一分钟。随着最后期限的临近，我不得不通宵在笔记本电脑上完成它。第二天我感觉眩晕，开始咳嗽和打喷嚏。毫不奇怪，这不是一篇很好的文章。然而，这给我上了宝贵的一课。当我接到下一个作业时，我直接去图书馆找我研究所需的参考书，然后拟了草稿并列了提纲。经过仔细编辑和润色，结果是一篇比上一篇好很多的文章，并且在截止日期前几天它就在书桌抽屉里，随时可交。在我的学习期间，我会坚持这种方法。 Unit 4　Never too old to learn 英语　选择性必修　第四册　Y 返回导航 课文翻译 我记得在小组项目上与同学合作。每个人都被分配一个特定的任务，我的角色通常是制作幻灯片演示。我们会在学校的自助餐厅见面，相互交流想法，当我们学着团队合作时，我们会笑，会争论，然后笑得更多。我意识到学习不必是一个人的努力，与其他人一起工作比独立工作更有刺激性和效率。 Unit 4　Never too old to learn 英语　选择性必修　第四册　Y 返回导航 课文翻译 我记得第一次在上班时间拜访我最喜欢的教授，一位高个子的绅士，胡子和头发都变灰白了。起初，我觉得他的严格令人生畏，但很快就开始钦佩他渊博的知识和对学科的深刻理解。很快我就开始明白，许多大学教授非常愿意分享他们所知道的，并且他们的确真心实意地关注学生的智力发展。 Unit 4　Never too old to learn 英语　选择性必修　第四册　Y 返回导航 课文翻译 我听到父母在叫我，我又回到了现在的时刻。毕业典礼后我们坐火车回家。我从车厢的窗口向外望，世界正飞速地驶过。回家的旅程让我有时间思考我的未来。大学改变了我。我现在不仅在智力上为工作的世界做了更多的准备，而且对自己的能力也更有信心。我已经长大成人，也对自己有了更多的了解。是的，我已经准备好迎接人生的新阶段。 Unit 4　Never too
