英语作文求修改！拜托了~ Reflection essay Neither the worldwide known buildings, such as Capitol Hill, Lincoln Memorial and Washington Monument, nor the popular places on-campus, like Gelman Library and Marvin center, the place which provokes my strongest feelings is the Pelham common room, located in the basement of West Hall, Mount Vernon campus. Firstly, the environment in Pelham is amazing and food served there is new to me, which makes me feel awkward and frustrated when I make choice. The first time I stepped into Pelham, I hardly believed it was a dinning hall, since it was super clean and the surrounding seemed to be too beautiful. It is so tidy that I have never seen any trash on the floor up till now, and chairs and tables are always in order. Sitting besides and looking through undefiled French windows, I can see blue sky with clouds flowing on, towering trees standing by the road and yellow and red flowers waving in the breeze. There are interesting photos about cuisine in the world hanging on the wall, which promote my appetite, or to be more specific, only curiosity of the taste after the time I had some Fettuccini Alfredo. As most of the food is Italian style, I can not pronounce their strange names or get accustomed to their tastes, so I always recall the food served in my high school dining hall which was tasty and cheap. Frankly speaking, the thing I miss the most is the time when my dear friends and me sitting together, chatting happily and enjoying the food. Though I do not get used to the food, I love Pelham because staffs here are so friendly that even give me a sense of family. Maria, who sometimes gives me some “discounts”, is the first staff to chat with me. She was so interested in the reason why I always made the same order and I shyly told her that I even did not know how to pronounce the Italian words. She laughed, and lovely whispered to me that she did not know all of them, either. James was also interested in the question as Maria had and began our first chat by asking it. During the spare time, he told me about his early experience in Germany, and sometimes complained about the tire and busy the current job brought to him. I told him that I failed in my Calculus midterm and he comforted me by telling some jokes of his daughter which made me feel much better. His accent is hard to understand but I like to chat with him, because he looks like my departed grandfather and presents his true concern about me. Another nice guy is Sam, who teaches me one Spanish word every time I encounter him and so far I have learnt “Mr., Miss, Mrs. and Thank you” in Spanish. I know common place like Pelham does not have great historical meaning which may make the reflection essay less impressive. However, Pelham invokes my recalling of the joy in high school which I currently miss much. More importantly, it helps me to get used to new life and build new friendships with people around me, which, I believe, I will value much more in the future.

eve法律帝请进本人18周岁未满,（9月满）高考完想去星巴克做"社会实践" 因为他们不招短期兼职,不招非大学在校生. 我与他们店面经理沟通时说 "我做的是社会实践,不是兼职/我不需要用工资形式来实现星巴克对我劳动的回报,比如一份肯定我的实习评估报告也非常好/我已经被美国xxx大学录取了,是enrolled student/" 店面经理称他要请示人事部. 我就走了...... 鉴于他有可能是敷衍我,我打算继续跟他抗战下去. 他不断地用<劳动法>来反对我的申请. 所以我想请问有没有办法钻劳动法的空子? 或者说,有什么办法让我的社会实践申请顺利通过.

新人报道 RT.. 另外.. 发10贴啊...太困难了.. 回帖行么.. ...话说我觉得我另外一个贴能算俩... ......

有看《我的错都是大人的错》的娃儿么前几天, 数月不上学的我回到学校, 耐不住高三的无聊机械...(好吧,我错了) 找同学借了<我的错都是大人的错> 当天看了4遍啊...混完了所有的课然后晚修继续... 把最后一节的摘录到空间里,全手机手打的呀... 其实最喜欢的是开头的那些话, 但是因为是孩子与父母间的对话,不太想摘. 然后,我猜整本书应该都是孩子与父母的话, 不过相对来说,最后一节比较男女了... 嗯嗯...这是发贴.. 10贴....10贴..

关于<亲爱的的安德烈>,你们想到的? 我自己先说, 在杂志上看转载的时候,第一感受是龙应台是我妈妈就好了.(额,当时我才14,5岁) 后来看了全书以后,对安德烈好感大增. 有段话记得很牢 "这是一个关于阶级跟贫富差异,社会公义的电影.我是和老爸一起去看这电影的.老爸开着BMW745的车,我穿着一件Ralph Lauren的白衬衫,我们住的小镇,是全的国平均收入最高的小镇--那我不正式这电影中的"坏人"吗?世界上有那么多人在饿死的边缘,我们开豪华的车是不是不道德?有些人做一天的工还赚不够吃的,而我只是上学,什么工都不必做,生活舒服得像个小王子一样,我可不可以心安理得呢?我也知道,电视在操纵,玩弄人的思维和价值观,但是我继续坐在那里看电视.我也知道,物质满到一个程度,就失去意义,但是我仍旧享受物质的满." "这是世界,是不是真的没有什么值得"反叛"的东西了呢?这个社会是不是真的,如我前封信所说的,没有什么不公不义值得我们去"革命",没有什么理想和价值值得我们去行动呢?" "我想是有的,还是有的." 单单一个我,也只是做到"知道"而已.还比不上安德烈"我清楚的知道自己的生活状态,并且至少,我并不以此为荣." 当然,我的生活状态比他差多了... ......现在觉得帖吧的会员名世界公民很贴切.. 2贴够了吧....我可全都是手打的
