当新学期来临时，许多学生对新生活表现得很兴奋。在大学，新生快乐地享受着自由。在接下来的四年里，他们希望过着高中描绘的\'美好生活。但事实是，大学生活中有很多东西要学。
First, the major knowledge occupies the most important role. As a student, learning knowledge is their job, while many students focus on playing cellphone in the class, or just sleep. They lose interest in studying when they come to the free environment. Mastering the professional skill helps them to be competitive. The sad thing is that most of them can't realize it.
首先，专业知识占据着最重要的角色。作为一名学生，学习知识是他们的工作，而很多学生在课堂上玩手机，或者睡觉。当他们来到自由的环境后对学习失去了兴趣。掌握专业技能帮助他们提高竞争力，可悲的是，大多数人没有意识到这一点。
Second, as there is much free time, they can make use of it and gain the valuable experience. Students can join some clubs to develop more interest, or find part-time jobs. It is better than to stay in the dorm and play computer games all the time.
第二，由于空闲时间多，他们可以充分利用好这些时间，并从中获得宝贵的经验。学生可以参加一些活动来发展更多的兴趣爱好，或找份兼职工作。比呆在宿舍玩电脑游戏好多了。
A lot of students feel lost in the campus, because they don't plan campus life well. The things you learn will make you different in the future.
很多学生因为没有计划好校园生活在所以迷失了。所学到的东西会让你在未来有所作为。

i have never been to troy, but david maule made me feel as if i were standing on the high wall of troy, watching the fierce war. thanks to this british author, who adapted the famous homer’s poem into a lively story, i found it easier to understand this story. though the story happened over 3000 years ago in a remote place, i was deeply fascinated by it.
the mysterious plot is one of the reasons why i loved the story of troy so much, yet i am more interested in the human heroes of the war.
hector was the eldest son of king of troy, priam. he was not only a real hero of trojan, but was regarded the highest moral hero in greek classic by later historians. the war started because of the mischief of his brother, paris, whom he didn’t appreciate. however, since hector was the commander of the trojan army, he was obliged to fight with all force. it was really a tragedy that such a valiant man died in the duel with another great warrior, achilles.
it is natural to see death in a war. as a famous chinese parable says, “a life can be as slight as a piece of feather, or as weighty as mount tai.” sometimes, one’s glory walks hand in hand with one’s doom. achilles was such a typical person. his personal charm made the story of troy more attractive. he was so crucial because his every appearance in a war encouraged his fellow soldiers and terrified the enemies. actually, achilles was half-god who was almost invincible in people’s mind. that’s why his name was memorized long after his death.
besides the two great men, the wisdom of odysseus also proved him to be a great hero. he didn’t want to attend the war because he was happily married and had a lovely son. however, since his country was allied to mycenae, he had to take the command given by the king of mycenae. i’m quite sure that the story of the wooden horse is widely known, however, few people know who thought of the brilliant idea, that’s why i admired odysseus so much because he was the person who got the idea. thanks to the horse, the ten-year war came to an end at last. if you want to know how the wooden horse worked, just read the book.
the ancient greeks believed that the gods and goddesses also played important roles in the origin, process and ending of the whole story.
the story of the golden apple was such an example. when eris, the goddess of argument and disagreement, threw out the golden apple to a wedding ceremony on mount olympus, a dispute happened. hera, the queen of gods, athena, the goddess of wisdom, and aphrodite, the goddess of love and beauty, were all involved in the argument for the apple. none of them was willing to give way, so they turned to paris for a final judgment. tempted by aphrodite’s beauty and promise, paris handed the apple to her. to keep her word, aphrodite helped him to get helen, the most beautiful woman in the world, as his wife. that was the cause of the war.
paris’s choice obviously annoyed the other two goddesses. so during the war, they helped the greek alliance army while some other gods, such as apollo and aphrodite, guarded troy. when paris dueled with helen’s former husband menelaus, aphrodite saved paris when he was about to be finished off.
after the duel between those two people, there was a truce between the greek alliance and troy. however, both hera and athena were not happy to see it. hera pursued her husband zeus:“ now, will you send athena to make the troyjans break the peace?”(page 22 then with zeus’s permission, athena went down to start the war again and finally she brought the greeks to success.
from the whole story, we can see that in ancient greeks’ view, gods sometimes played a much more important role in their life. however, with the rapid development of science, we have learned that the greek gods never existed. this is why a recent movie of troy has not mentioned a single god. everything happened due to men’s ambition, love, loyalty or jealousy. with those emotion and people’s effort, we human beings can accomplish wonders and be master of the world.
god are of less importance than they used to be. nonetheless, the gods and goddesses made the story of troy more mysterious and marvelous.
i have learnt from the book more than the wonderful story of history, love and war. i believe that human can determine their destiny by their own. i highly recommend this book to my friends.

阅读了《自然辩证法》序论和恩格斯的《自然辩证法》导言，我大体明白了自然辩证法所研究和揭示的资料：自然界存在和演化的一般规律，即自然界的辩证法;人类经过科学技术实践活动认识自然和改造自然的一般规律，即科学技术研究的辨证法;作为一种认识现象和社会现象的科学技术发生和发展的一般规律，即科学技术发展的辨证法。
从这个定义中能够看出自然辩证法能够为科学技术的发展供给正确的世界观和方法论的启迪，以帮忙和促进科学技术的认识和实践，同时自然辩证法不可能也不应当以自我的哲学研究来代替自然科学的实证研究。
这其实也就给出了“你觉得经过专业课程的学习能够解决科学方法训练、本事和视野的问题吗?”这个问题的答案。要在每一个专业领域内有所发现，必须要先学习该专业的基本知识，了解该专业的一般规例。这些专业课程的学习能够在必须程度上训练我们使用合理的科学方法，提高我们的本事，开阔我们的视野。可是要深入的研究这一专业的知识，
并开阔这一专业的领域，在这一领域内有所创新，我们必须对这一专业又更广更深的理解。而这种理解，是离不开正确的科学方法，和广阔的科学视野的。我觉得这种更一般性的科学方法训练、本事培养以及视野的开阔是由研究自然科学的自然辩证法以及其他一些相关知识所能供给的。
也就是说，除了专业课的学期，我觉得能够为我们供给科学方法训练、提高本事和开阔视野的知识很多，哲学，历史，文学都有我们能够汲取的营养。关键是看我们能不能从这些专门知识中提取出对我们认识自然，进行科学研究有益的观点。
恩格斯在《自然辩证法》导言中，首先回顾了几个世纪以来自然科学的发展，批判了以往形而上学的自然观，然后阐述了自然界是运动变化的辨证唯物的自然观。

《自然辩证法》导言，体现了恩格斯自然辩证法的总体思想。
历史的发展是任何力量也阻止不了的。“哥白尼革命”使“自然科学从此便开始从神学中解放出来”，获得了自我发展的权利，开始了新的历程。当然，在中世纪，自然科学的蓬勃发展，是科学家们用鲜和生命顽强斗争而开创的历史。科学是人类智慧的结晶。
科学的发展必将推动人类认识的提高、促进哲学思维的发展。正由于此，恩格斯在《自然辩证法》导言中，经过对自然科学的历史考察，阐述了自然科学发展的规律;同时，恩格斯还以很多的科学史实为依据，说明由于自然科学本身的发展，辩证唯物主义自然观代替形而上学自然观已成为历史的必然。
近代，自然科学多数处于搜集材料阶段。由于力学有了较高发展，人们似乎以为力学规律是万能的，企图用力学的观点去说明千变万化的自然现象，把自然界中的各种运动形式都归结为机械运动，这就不可避免地会产生机械论的`观点，从而逐渐构成自然科学研究中长达几个世纪所特有的局限性——形而上学的思维方式。这种思想方法和研究方法被培根和洛克移植到哲学中来，就构成了形而上学的自然观，其中心思想是“自然界绝对不变这样一个见解”。形而上学的自然观从本质上来说，是与自然科学相悖的，阻碍着自然科学的提高和发展，并且最终使它陷入神学的禁锢之中。由于产业革命的推进，自然科学的研究方式也起了根本性的变化，由搜集材料的阶段进入到系统地整理材料并把它们上升到理论概括的高度。自然科学各领域的划时代发现，导致形而上学自然观的破产，恩格斯在此基础上以辩证唯物主义为指导，确立了新的自然观。从古代朴素的自然观到近代形而上学的自然观再到辩证唯物主义的自然观，完成了人类自然观的伟大变革。
恩格斯以辩证唯物主义的自然观为指导，具体地描绘了从原始星云到地球，从无机界到有机界，从生命起源到人类社会产生和发展的图景，证明自然界的一切归根到底是辩证的而不是形而上学地发生的。恩格斯以物质永恒运动和无限发展的思想为指导，说明自然界总是处于各种运动形式的生灭转化之中，整个自然界就是在这种转化过程中展开自我的发展历程。恩格斯最终论述了辩证唯物主义关于自然界无限循环的重要思想并确立了它在辩证唯物主义自然观中的重要地位。
读完恩格斯的《自然辩证法》导言，我掩卷沉思。在恩格斯的眼里，历史上所有的科学成就如数家珍，娓娓道来，对此感到异常佩服。这是对知识掌握到必须层次的境界，一种永远激励我们后人上进的境界。经过《自然辩证法》导言的学习，对我启迪最大的，是前人博大的哲学思想，是前人为科学奋斗甚至献身的精神，当然，那些分析问题、解决问题的科学方法更是值得我们去学习和借鉴的。
能够这样说，学习辩证法，是时代发展的要求。当前人类社会已经进入信息技术化、经济全球化的时代，科学技术与社会的关系更加紧密，在这种情景下，我们要促进科学技术的发展，并经过它来推动社会经济的发展与社会同步，就必须深入研究科技发展的内在规律，就必须将科学技术置于社会大系统中。学习辩证法，也是我们探索自然界奥秘的需要。并且，研究自然辩证法，有助于我们创新意识的树立和本事的培养，能够使我们在科学精神与人文精神相结合上，提高整体素质，更加适应当代社会发展的需要。
我们应当永远牢记，“地球上的最美的花朵——思维着的精神”，更应以前辈科学家们用鲜和生命顽强斗争而开创自然科学蓬勃发展历史的精神为榜样，力争开创我们事业的新天地。
