每个人都有梦想，我的梦想就是当一名科学家，每天发明出各种各样的东西来为人们服务，让每个家庭更轻松的过上好日子。
我想发明一种自动清洗玻璃，这种玻璃自带清洗功能，可以自动清洗玻璃上的脏东西。这种玻璃可以用在高层建筑物的窗子上，因为它不需要人工来清洗。
人类现在使用的交通工具大多是用电和用油的。用油的汽车尾部排出来的是一氧化碳和多种有害的气体，如果有人不幸中毒就必须尽快治疗。我想让那些用油的机器都改造成用太阳能电池板来制作动力，这种发明只能在有阳光的条件下才能使用。当然，太阳资源不是天天有的，也有阴天的时候。假如我是科学家，我会发明一种阴雨箱，作用是能吸收阴雨天的能源，这样无论在晴天还是阴雨天都可以使用交通工具，而且它们排出来的气体也不是有害气体。
我想发明万能房子，房子的门是自动识别门，能自动识别外面的好人与坏人，还能识别是不是主人，如果不是，门就会自动加固，就是用大炮也别想把门炸开。这种房子中还有电影房、游戏房、娱乐房和驾驶舱。不仅如此，还可以把房子变成一辆汽车，这种房子里安装了自动清洗机器人，看到一切脏东西就会去处理。要用的东西他会马上清洗干净，不要的东西就立刻处理掉。在遇到洪水、泥石流、地震等这些自然灾害，房子就会自动听随主人的命令去到安全的地方。
这就是我的梦——成为一名科学家，发明一些前所未有的事物。

When I was a freshman in college I watched the film Gua Sha Treatment for the first time, now I am a junior student and I come back to review the movie from a multicultural aspect, I have many different feelings after watching the film again.
At the beginning of the film, XuDatong is given an award and later he delivers a speech. What makes me impressed most is in his speech he says “one day I will become one of you, a truly successful American, today this award proved that America is a true land of opportunity and I am the living proof of that.” At that moment Xu thinks he has realized his American Dream totally with his lovingly wife and adorable son. However, I think it is ironical that to make a speech like that and I assume it is made on purpose to hind a clue for the story's development. How many non—American people have such a beautiful American dream? One of my classmate studies in American now and before he went aboard he told me his American dream is he can stand at the top of the New York. To be honest, I also dream that one day I can get the Green Card living there happily and successfully maybe working at the Wall Street. When Xu gets the award he thinks he entirely melted in the melting pot neglecting the multicultural obstruct, later the plot goes against the way he thinks. And later Quinlan asked Xu'why you be the scapegoat of your father?' Xu answers 'because he is Chinese.' Then maybe Xu knows that there is always a wide gap between Chinese and American cultures.
The second scene is Xu hit his son Denis because Denis hit the son of xu's boss, at the middle of the film xu tells his boss that he hit his own son is only to show his respect to his boss John Quinlan, that time Quinlan feels puzzled “what a Chinese logic”,yes, American can never understand such a logic full of Chinese characteristic, because they respect everyone including the children, they won't beat a child to please the boss, and there is no such a conception of degree between employee and employer, they feel everyone is equal, which is quite different from china.
Connected to the second scene, the third difference I want to analyze is the care for the children. In America, people pay more attention to the right of children which can be seen from the law—leaving children alone at home is illegal, while in China it is so common that almost everyone may experience such loneliness. And Children Welfare Agency does work in America which shows the importance Americans attach to children's right. What's more, I remember a line 'No one won the case, especially the child.' In my opinion, it also manifests the universal concern from the American public to the children.
The fourth aspect is following the procedure, in the film, more than there times, the people focus on the rule, the law, the procedure. At the Christmas Eve Xu wants to return back to his home pretending as a Santa Claus, what a pity, the security recognizes him and persuades 'you are always a good tenement, never causes troubles for me.' And another scene is at the end of the film , the judge says 'I have to follow the procedure.' However, in China people always have to ask for a favor to do something, and later you have to pay back the favor,for myself, I prefer the American style, strict to the procedure.
The fifth and the last point is the humors, Quinlan says 'you can't fall, your health security is the company paid.' 'Datong, welcome home, maybe next time, you can come from the front door.' 'dady, why you come from the window' ' because we don't have a chimney.' I really adore this distinguished American humor, especially in dangerous situations, which is quite rare in China.
That's my whole reaction to Gua Sha Treatment.

每个人都有自己的理想，而我的理想是想当一名科学家，为人类多做贡献！
假如我是科学家，我会发明一种工具，它不仅能在陆地上跑，还可以在空中飞翔，每秒钟的速度可达1000米，还可以在水里自由自在的游来游去，每分钟可以游20xx米呢！
假如我是科学家，我会发明一种独一无二的药，这药能治各种癌症，绝症，解除人们的痛苦，连最近的“非典”也要“下岗”了！
假如我是科学家，我会发明一种汽水，它可以使疲劳的足球员立刻提起神来，那是因为，面含着没有毒副作用的兴奋，人喝了，精神细胞扩大，精神会越好。所以，我门的球员一定精神十足，一下把球踢进了对方的球门。踢出亚洲，踢出成绩。
假如我是科学家，我会发明一种衣服，这衣服会根据大小，天气，颜色不停的改变，那是因为这衣服有100多种原料组成，只要天气一变，衣服就会缩小变厚，不容易进风，如果天气热了，它会立刻变浅变薄。如果吃饭弄脏了，它也会立即变的滑滑的，不让污渍有一刻的停留。
这些都是假如，如果是真的，那我们的世界该多么美妙啊，你们说呢？！让我们一起努力吧！

如果我是科学家，我会发明出许多有利于人类的东西。什么，你不信？那就听我一一到来吧。
如果我是科学家，我会发明出一种“多功能衣服”，这种衣服可不比其他的，它可是有多功能的哦。它是用一种万能纤维做的，有着“火烧不着、水浸不到、电打不烂”的功能，这种衣服还本身就是个按摩器，随时随刻都帮你按摩，让你不知不觉地享受。这种多功能衣服还冬暖夏凉呢。
我还要发明出一种“超级手表”，看过“快乐星球2”吗？我的超级手表就是按照艾克的“万能手表”制造的。当然，不会有它那种特神的`功能了。这种手表有二层，平时用来看时间。第一层用来看电视、电影，无聊时还可以用来听mp3呢。第二层可以用来看各种报纸，各种书籍。查阅各种信息、资料。晚上还能用它来照明呢。它还有一个更神奇的功能，那就是能和自己的朋友、亲人通话呢，只要你按一下手表左边的按扭，然后再说要和谁通话就行了。你不信也没办法，科学就是那么神奇。
当然，我要发明的东西不止那么多。下次再说吧。
