How I Turned to Be Optimistic

I began to grow up that winter night when my parents and I were returning from my aunt's house,

and my mother said that we might soon be leaving for America. We were on the bus then. I was crying,

and some people on the bus were turning around to look at me. I remember that I could not bear the

thought of never hearing again the radio program for school children to which I listened every morning.

I do not remember myself crying for this reason again. In fact, I think I cried very little when I was

saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was

going to see - the strange and magical places I had known only from books and pictures. The country I

was leaving never to come back was hardly in my head then.

The four years that followed taught me the importance of optimism, but the idea did not come to me

at once. For the first two years in New York I was really lost-having to study in three schools as a result

of family moves. I did not quite know what I was or what I should be. Mother remarried, and things

became even more complex for me. Some time passed before my stepfather and I got used to each

other. I was often sad, and saw no end to "the hard times."

My responsibilities in the family increased a lot since I knew English better than everyone else at

home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my

grandparents to the doctor and translated there, and even discussed telephone bills with company

representatives.

From my experiences I have learned one important rule: Almost all common troubles eventually go

away! Something good is certain to happen in the end when you do not give up, and just wait a little! I

believe that my life will turn out all right, even though it will not be that easy.

阅读下列短文，回答文后五题。
艺术需要近距离。近距离地看画展、听音乐会、看话剧……现场，带给我们另一个视角，另一种全新的感受与体验。苏东坡诗云：“不识庐山真面目，只缘身在此山中。”但有的时候，要想真切地感受此山，还是需要“白云回望合，青霭入看无”的登山经历。对于艺术体验，尤其如此。现场，是心与心之间一次深刻的交流与融会，一次彻彻底底的惊喜与感动。
真迹带给人视觉冲击最大的无疑是梵·高的画。几年前举行的日本富士会馆藏品展中有几幅梵·高的画，那浓重的色彩、喷薄的激情，一种燃烧的感觉，令人不敢逼视又无法移开目光。梵·高是非常重视事物的客观形似的，但他的画却给人一种强烈的主观感，也许从他非凡的心灵与双眼中看到的世界就是如此。而我辈凡夫俗子，平日里早已蒙尘的心灵与双眼，只有从他的画中才得到少许的拂拭，看到另一个不一样的世界，感到亘古的时空中有我们不可理解的梦幻。绘画艺术的奇妙就在于此吧。
话剧也是一种面对面的艺术，好的话剧常常予人酣畅淋漓之感。几个月前，我在海淀剧院看了根据雨果同名小说改编的话剧《九三年》。我本来没有抱太大的希望——雨果原著中那大段大段的议论与抒情是很难以舞台形式表现的，而且中国人演老外也难免有点“隔”的感觉。没想到这台话剧从灯光、布景到演出精彩绝伦，人性的高贵与卑劣、原则与亲情、革命的残酷与人道主义的关怀都交织在尖锐的戏剧冲突之中，一段长达8分钟的独白也是一气呵成，荡气回肠，观众的掌声亦经久不息。
……
生命是一个漫长的旅程，每个人所走的路、所见到的风景其实很有限，而艺术，是扩展我们心灵、丰富我们经验、让我们更好地认识到人类生存处境的最好的手段。
(选自鲁竹《艺术需要近距离》，节选)

根据上面的内容，请概括本文的中心：

A．艺术需要冷静、客观地去审视。

B．艺术需要近距离。

C．艺术能陶冶我们的情操。

D．艺术是人类认识生存处境的最好的手段。
