老街灯

王月鹏

  这是最后一夜。当晨曦升起,当那个叫做“明天”的日子如期降临,老街灯将永远地告别这条街道。

  已经多少年了,它一直守望在这里。街道的秘密,就是它成长的细节。那些匆忙的步履,那些徘徊的心事,喜悦或悲伤,孤独或喧嚣,都曾经走进老街灯温和的目光。老街灯珍藏着它们,永远不会说出口。

  老街灯的存在,仅仅是为了对一条街道的守望么?当它的光越来越孱弱,终于无力继续照亮别人的路的时候,那些曾经被它照耀过的人,并没有为它指明一条道路。离开了这条街道,老街灯不知道自己将要走上一条什么样的路。当它带着这条街道的所有秘密离去后,街道将仍然是那条街道,仍然布满匆忙的步履、徘徊的心事,仍然上演着一幕幕的喜悦或悲伤,孤独或喧嚣。

  因为别人的遗弃,老街灯成了守夜人的珍藏品。在离开那条街道之前,它从来没有想过,自己与守夜人原来是如此的默契。守夜人和他的妻子也老了,这条街道,这盏灯,已经成为他们生命中不可割舍的一部分。这么多年来,守夜人从来不揩老街灯的一滴油。现在,他拥有了这盏“退休”的灯。它就被搁在火炉旁边的一个靠椅上。我相信老人独自凝望它的时候,心底一定会涌动很复杂的想法。老街灯曾在那些风雨之夜温暖过他,就像此刻它在陪伴着他的孤独一样。炉火的温馨,让那些风雨往事披上了一层暖意。那些相依为命的日子是值得回味的。老街灯记得,守夜老人每个星期日下午总喜欢读一些游记类的读物,他高声朗读着那些关于非洲、关于大森林藏有野象的故事。他从未离开过这条街道和这盏灯,他的心里有一个关于远行的梦想。

  是命运不肯放走他。当他终于可以走开的时候,却不知道自己接下来将要遭遇怎样的命运。有些东西,其实是我们无从把握的。就像在奔往某处景观的途中,我们无法拒绝沿途的景致一样——不管是令人愉快的还是忧伤的。甚至,它们的存在,或者这种存在所呈示的意义,已经远远超过作为目的的所谓“景观”。而这一切,常常被我们发觉,却又很难做出有违初衷的选择。人的一生就这样固执地走了下去。

  而守夜老人留了下来。还有老街灯,也一直留在了那里。我们忽略了他们的存在。我们是匆匆的赶路者。

  因为搬家,我翻阅起了旧的习作。它们已在牛皮纸信封里尘封十多个年头了。我无法让自己不按照当下的心态和眼光去重温那些文字。我在翻阅它们的时候一直在努力让自己回归当初的心境。这些稚嫩的文字,它们收留了我的青春,遥远并且质感,它们打动了我。我珍视这份真实,并且期望写下具有同样品质的文字。多年以后,我也会像今天一样成为自己的读者。就像那盏老街灯,它曾经照亮了我的远行之路,也一直在记着我的回家的路。

  另一种现实是,难耐寂寞的老街灯主动走进熔炉,被铸成一架可以插蜡烛的漂亮烛台,摆到了诗人的绿色书桌上。那些曾经的风雨,于是在诗人笔下成为浪漫的风景。也许,这仅仅是一个梦。但这个梦让我有说不出的伤感。(有删改)

(1)下列对文章有关内容的分析和概括,最恰当的两项是(     )

A.文章第二段运用比喻的修辞手法,形象地说明了“老街灯”在人们生活中的重要作用,表达了人们对“老街灯”的怀念之情。

B.“老街灯”“燃烧”了自己,照亮了别人,最后却被人遗弃,这充分说明了人的喜新厌旧和冷漠无情。

C.文章第四段通过写“守夜人”对“老街灯”的珍惜,告诫人们对曾经在我们的生活中有着重要作用和影响的事物一定要懂得珍惜。

D.“老街灯”老了,“守夜人”老了,凡是老了的人和物,都必将随着时光的流逝而被湮没,不值得人们留恋,不值得人们伤感。

E.文章最后通过对梦想的描写,含蓄地揭示了一个深刻的哲理:任何一个人或物,如果不想被时代抛弃,就必须顺应时代潮流而相应地改变。

(2)如何理解“老街灯的存在,仅仅是为了对一条街道的守望么”这句话在文中的含意?

答:____________________________________________________

(3)文章题目是“老街灯”,作者为什么要写到“守夜人”和“旧的习作”?

     Lisa, a 25year old from Beijing, recently places a number of very unpleasant statements on the

Internet regarding the elderly.They include things like "don't  rely on others", "don't expect others to

help", "don't be talkative", and "dont't be so stubborn". The underlying message was that elderly

people should not take advantage of their old age to demand special favours from others, particularly

from the young.This of course flies_in_the_face_of the Chinese tradition of respecting the elderly.But,

in my opinion, Lisa's "requests" might not be totally unreasonable.Old people do sometimes behave

like they're "stubborn"and "talkative". Still, the young woman is rudely insensitive to why the elderly

behave that way.As people get old, they become increasingly weakened physically.So it's natural for

them to ask for more help from others.As their memories decline, they tend to be talkative because

they easily forget what has just been said.The American psychologists D. R.Atkinson and G. Hackett

said that the brain is characterized by flexibility.It has the ability (most pronounced up to the age of 12)

to change itself as a result of experience.But, as the brain ages, this flexibility decreases.As a result, the

elderly are often inflexible in their ways.

      Therefore, old people need real care and deserve to be taken care of.Many have devoted most of

their lives to the wellbeing of the family or social.Their aging is no reason for showing prejudice (偏见)

to them. According to Chinese tradition, older people are to be respected.As are Westerners.

     I live in the US for eight years, and in Hong Kong for 13.Never have I seen or heard anyone who

would openly tell old people "to behave themselves".

     We may encourage old people to be more selfreliant.But rudely demanding that they do so is ageism.

That's where the difference lies.

1. What does Lisa think of the elderly?

A. The elderly hate to rely on the others.

B. The elderly should take advantage of their old age.

C. They are not talkative but stubborn.

D. The elderly always demand special favors from the young.

2. The underlined part in the first paragraph can be replaced by"________".

A. expresses the apparent meaning of

B. shows disagreement with

C. deals with the surface meaning of

D. draws a conclusion from

3. What's the writer's attitude towards this problem?

A. The young woman is too sensitive to why the elderly behave that way.

B. The elderly naturally ask for more help from others, because their brain is characterized by flexibility.

C. The elderly are often inflexible in their ways, which makes the young suffer.

D. The elderly deserve to be taken care of and we shouldn't show our prejudice because of their aging.

4. The last three paragraphs really want to show that________.

A. we should respect the elderly

B. the people in the US or Hong Kong respect the older people

C. old people should be encouraged to be more selfreliant

D. different ideas about the elderly are allowed to exist
