    Why do we read poetry? First obvious one: because we enjoy it. The only other reason is for academic purposes, and that's not why this is here.

    Many of us read poetry simply because we often feel depressed and hopelessly lost, and in poetry we see how beautiful and strange everything is. So in that way poetry calms our anxiety.

    There are many different kinds of poems. They are not all calming. Some poems make me anxious, angry, scared, and sad, which is why I value them. As a reader, I want a full meal, not just dessert. I want the sweet and the bitter. Often, I read poetry when I'm already relaxed. In fact, I read more when I'm not stressed out.

    Here are the main reasons I respond to poetry, as far as I can tell. Metrical(格律的) poems are about setting up rules and then bending them. Usually, this is done by setting up a rhythm and then violating it or almost violating it. And then returning to it again. This satisfies my desire for order and also my desire for testing boundaries.

    Poetry plays with language and often slams words together in surprising ways, which is thrilling the way food can be when the chef has paired ingredients you never thought would taste good together but somehow do.

    Many poems are dense. Words mean two or three things at once and lots of suggestions are packed between the lines. This is intellectually inspiring and it allows me to read the same poem over and over always finding new things in it.

    And, of course, there's the subject matter. It interests me just as it would if the same subject was explored in a story or essay. Not all poems interest me in this way, but then not all stories and essays do, either.

阅读下文,回答相关问题。

                                                                                                                                        乐山大佛
        ①在四川乐山的三江合口处,坐着一尊受香火的清廉大佛。
        ②他叫弥勒,弥勒佛。但不是那位袒露大肚皮的弥勒佛,那位成天笑眯眯的“老好人”——“大肚能容天下难容之事,慈颜常笑世上可笑之事”的弥勒佛。
        ③他是一位严肃的沉思者,面色温和,神情严肃。他不是什么都笑——世上并没有那么多可笑的事,也不是什么都容——天下一切丑恶都容。
        ④他的严肃的思考,首先来自缔造他的海空和尚。一千一百多年前,凌云寺和尚海空为了减缓三江合口后的凶猛水势,避免沉舟淹死众生,倡导在峭崖临江边造就一座佛。他光头顶烈日,下雪披袈裟,四处化缘,钱化得不少了,但当地官吏要冻结:“如果你真心造佛,就把眼珠挖出来见我。”
        ⑤大佛兴建了,海空的眼珠也没有了。海空的眼珠是为建大佛而失去的。世上除了生命,还有比眼珠更珍贵的东西吗?
        ⑥由于意识到自己的职责,因此,乐山乐水佛不乐。他坚守岗位,从不擅离职守,从不懈怠松驰,从不向惊涛恶浪屈服。他成了实现海空和尚遗愿,拯救三江芸芸众生的中流砥柱。

        ⑦他常常想起塑造他的工匠们。是的,他是伟大的:头与山齐,脚踩江水,身高71米,比阿富汗世界第一大佛还高18米,可称世界第一伟佛了。如果不是设计、雕塑他的工匠们经过九十年的千刀万凿,他仍然是半片石头山,普普通通通到处可见谁也不会瞄一眼的石头山。为了他的降生,有多少人摔下峭壁,跌进的江心,付出了生命!他是真正的人民之子。
        ⑧他永远不忘这最根本的一点,因此他从不居功,从不索取,从不接受人民的香火和祭祀。在这里,看不到一柱香火,一支红烛,一从跪拜,看到的只是他伟岸的身躯,两袖清风,一尘不染。为了根绝香火,他一开始就釜底抽薪铲除了滋生这些东西的土壤:立脚点在临江的悬崖上,没有地方让人设立祭祀他的殿堂,周围全是香火插不进的岩体,连他的脚趾甲也是向下倾斜的,人站上去就会跌倒,所以连下跪朝拜也没有地方。
        ⑨人们只能簇拥在轮渡上才能看到他那顶天立地的尊容并默默遥致祈祷。
        ⑩有人感叹,有人惊奇,有人礼赞:“呀,连小小的土地庙都有几柱香火哩,而他——世界第一大佛,连一柱香火也没有。
