I saw a Sentence several days ago," The most sad thing in the world isn't departure but distance."
前几天我看到一个句子,世界上最令人悲伤的事情不是别离而是距离.
particularly,the furthest distance.
特别是,最远的距离.
It reminds me of the poem by Tagore.
这让我想起泰戈尔的诗.
”The furthest distance in the world
　　Is not between life and death
　　But when I stand in front of you
　　Yet you don’t know that
　　I love you
　　The furthest distance in the world
　　Is not when I stand in font of you
　　Yet you can’t see my love……”
　　　世界上最遥远的距离,不是生与死
　　而是我就站在你的面前,你却不知道我爱你
Most of the time,we are not understood by others.
很多时候我们不被别人理解.
Actually,I want to own a huge number of friends,but I know it is out of the question.I just let it be without thinking too much.Those who are doomed to be my friends will come to me naturally,while those who are not can barely be retained once they want to leave from me.When friendship comes to an end,it is no need to sigh and insist.Rather,we should get rid of the pessimistic side and showcase our most graceful personality to others.We should live a life with our lives,because we are living not for pain,but for happiness that stems from mutual understanding.
我想永远拥有许多真心的朋友,但我深知这是不可能的.离散聚合,应顺其自然,不必勉强.属于我的朋友,会向我走来,不属于我的朋友,留也留不住,如果真到了一躬而别的时候,无须哀怨,更不能太计较太执著了,权且将人生悲凉灰颓的一面独自吞咽,再将亮丽壮美的品质展示给他人,用生命去体验人生就是.因为人活着不是为了痛苦,人生乐在心相知.
Please cherish your friends no matter what happens.Maybe your friendship will not last long or will be forgotten one day,but you should attach enough importance to it.It is a seed that will bud,grow leaves,blossom and even bear fruits in your heart once you care about it.The flagrance from the blooming flowers will accompany you all your life……
珍惜身边的每一份友情,无论它是不是已经过去,无论它会不会有将来.也许不会天长地久,也许会淡忘,也许会疏远,但却从来都不应该遗忘.它是一粒种子,珍惜了,就会在你的心里萌芽,抽叶,开花,直至结果.而那种绽放时的清香也将伴你前行一生一世……
后面的两大段我希望帮我改简单一点,我是高中生,不能让大家听不懂,我自己也看不懂,泰戈尔的诗也不用改.

Actually,I want to have a huge number of friends, but I know it is impossible . I just let it be without thinking too much. Those who are doomed to be my friends will come to me naturally, while those who are not can barely be kept if they want to leave me. When friendship comes to an end, there is no need to sigh or stick to it Instead , we should get rid of the pessimistic side and show our most graceful personality or our most realistic selves to others. We should live a life with our lives, because we are living not for pain, but for happiness that comes from mutual understanding.

（我去掉了你的一些“big”单词,因为它们实在没有必要.我敢肯定,你们的英语老师can't write as well as you.）
再问： 重点看一下语法吧……前面几句的。
再答： 1 several days ago--------the other day 2 The most sad thing -------the saddest thing 3 其它的地方我已经为你订正好了，请认真阅读
