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.
yesterday i read a book the name of the book is《dr bethune》.
dr bethune was a famous doctor from canada. in 1938 he came to china. at that time china was at war with japan. he worked as a doctor in the chinese army and saved many soldiers’ lives. he worked very hard and became sick. dr bethune died in 1939. he was only 49 years old. he was a good man and we remember him today.
i think the book is very very good!

how to do research
——reading after a science paper
these days i am busy preparing my dissertation which is about web usage mining . i read some english papers and learnt much from them . and now i want to say something about a paper titled “web usage mining:discovery and applications of usage patterns from web data”.
this is the first english paper i read about dissertation and gave me great help .
this paper is a review about web usage mining. it introduced web usage mining in detail . although it is a little old for it was published in its contents are very useful today . it is organized according to the sequence of web usage mining and the six main parts are introduction which tells me what is web usage mining the sources and abstraction of web data the three steps of web usage mining taxonomy and project survey websift overview privacy issues . the third and fourth parts are most important . it had a list of existing project about web usage mining which i saw many times in other papers but this paper is the one creating this list . besides it has been referred for more then twenty times . as we all know that the higher the referred number is the more important the paper is so i consider this paper to be an important and successful one in this region.
in my opinion the success of this paper dues to three reasons . the first reason is the profound computer knowledge owned by the authors . web usage mining relates to many subjects such as artificial intelligence ontology semantic analysis but the most basic knowledge is computer science . the four authors are all professors of department of computer science and engineering in university of minnesota . for myself i am not major in computer science and i am not very good at computers so i feel a little difficult to understand technologies used in this region.
second they had read a large number of papers before they wrote this paper . there are fifty nine references listed after main contents . “stand on the shoulders of giants” this sentence tell us a truth : one can never successful all by oneself . and what’s more learn from others can save a lot of time and energy especially for us new learner . how to learn from others is a skill all of us should master but learning doesn’t mean copy or plagiary . other people’s knowledge and production is just our foundation upon this foundation we must have our own thoughts and creation. there are many remarks in this paper where referred other’s production.
third the authors had the experience of developing a web usage mining project . they don’t just engage in idle theorizing so their comprehension on this issue is greatly profound. they know what we may meet in a real project development and they know how to resolve them . after reading this paper i also read some other papers written in chinese . some of them are not based on real project and can not give useful resolution . websift is the name of system they developed which can be used to data mining and analysis .
i wrote this article not only because it gave me much help in preparing my dissertation but also because it tells me how to study and how to do research . honesty and preciseness are two essential making a researcher must have . hard-working is the necessary condition leading to success . this is just the beginning of my dissertation i should learn from these four authors both their knowledge and their attitude to study.

当电子游戏无情的封锁了我们的童年,当如梭的光阴叹息着人生的悲哀,我们已不知不觉的掉入了电子游戏这张铺天盖地的巨网,只留下被吞噬的灵魂和被侵蚀的青春。
古有鸦片侵蚀人的心灵,而在今天这个科技飞速发展的时代里,电子游戏已经如洪水猛兽一般席卷了社会的各个角落。鸦片一吸,不愿吐出;游戏一打,难以放下;因此,电子游戏被冠以新名头——当代鸦片。
综上所述,我想问:“电子游戏的魅力在于什么?”
在于他构建了一个虚拟的幻境,在于他把现实中的事物与感知移植到那个虚幻的环境中。在那里人们可以把酒临风,头顶长虹,脚踏落英,轻击鼠标就从杭州到了北京。在那里,人们可以褪去便服着戎装,征战沙场,谈笑四方,敲打键盘间就结束了无数敌人的性命。这一切似乎不费什么功夫,只要你肯花时间在屏幕前“打怪”,肯把精力或财物投入进度条。在那里,似乎什么都可以收获——金钱、声望、地位,甚至是爱情,于是人们欢欣鼓舞,流连忘返。
可那是我们真正的世界吗?那只是一个虚拟的,永远只能在屏幕上的世界。在游戏中是执长剑策骏马,但在现实中早已步入万丈深渊。要知道,真正的成功不是敲打键盘就能获得的,它需要无数次深夜中的哭泣与失败后擦干眼泪的`勇气;要知道,真正的喜悦不只是换上炫酷的装备那样简单,它的到来是需要相等的痛苦结伴后才有的;要知道,真正的情感是不可能用一个“亲密值”的满格来衡量的,它需要心脏无数次的交响与律动,需要真诚的付出与关心……
网络游戏是一个“无底洞”,它会一点一点的吸食你的灵魂,最后让人变成一具只有肉体的空壳。
那么就有人问了:“是什么原因让人们沉迷游戏呢?”
是家庭。根据科学统计结果来看,全国有65%的网民是青少年。而在这些青少年当中,又有50%的青少年是因为家庭因素而选择逃避。
一般来讲,网络成瘾的青少年,其父母对其从小的教养方式共同点是家长对子女行为过度干涉,在这种教养方式下成长的孩子,性格都比较孤僻,很难适应群体生活。由于在现实中得不到心理满足,就转向虚拟的网络世界寻求自我满足。
若要“戒网瘾”,我们必须从根源出发。现在的青少年并不是物质缺乏,而是在精神上缺少理解和关爱。家长们应该做到多陪伴孩子、多鼓励孩子、和孩子进行深度的沟通、不要谈“游”色变。
歌德有言:“谁若游戏人生,他就一事无成;谁不能主宰自己,便永远是一个奴隶。”莫等闲,白了少年头,空悲切!我们应该像林则徐那样坚决地把烟枪折断,将劳动的双手从屏幕上移开。用青春创造出一个真正看得见,摸得着的明天,而不是屏幕映出的一张空洞呆滞的脸。生活需要游戏,但不能在游戏中玩物丧志;生活需要歌舞,但不能在灯红酒绿中醉生梦死。现实中的美好感知,有着真切的触感和温度,绝非隔着冰冷的屏幕捕捉转瞬即逝的快感。
让我们告别电子游戏,拥抱魅力生活。
位置在下面称呼语隔一行,是信的核心部分。因此要求正文层次分明、简单易懂。和中文信不同的'是,正文中一般不用hello!(你好!
正文有缩进式和齐头式两种。每段书信第一行的第一个字母稍微向右缩进些,通常以五个字母为宜,每段第二行从左面顶格写起,这就是缩进式。
但美国人写信各段落往往不用缩进式,用齐头式,即每一行都从左面顶格写起。商务信件大都采用齐头式的写法。
