最后的沐浴

方叶

  (1)为母亲沐浴,是第一次,也是最后一次。     

  (2)母亲躺在床上,眼睛微微闭着,嘴角含着一朵淡淡的笑容,仿佛刚刚睡去。     

  (3)哦,母亲即将远行,去那一片永远宁静的净土,作为儿女的我们来为她做临行前的梳洗。     

  (4)默默地松开蓬松的发髻,我的手在颤抖,心更无法平静。沐浴过多少阳光风雨,堆砌过多少羞怯秀丽,编织过多少人生梦幻的秀发云髻,全都被漫漫的岁月漂白了。     

  (5)我知道辛勤而省俭的母亲似乎从来都没善待过自己的头发,平日连香皂都舍不得多抹几下。今天我们特意煮了一锅清香四溢的檀木热水,掺合这飘柔香波。轻轻搓揉,洗去发髻间每一颗结垢,剔去云髻上每一粒沙尘,让她一尘不染地上路,去寻找等待他多时的夫君。

  (6)骨骼本来就粗壮的手脚,因为肌肉萎缩,青筋暴涨,更峥嵘如古松了。渔家女出身的母亲,三岁丧父,九岁失母,从小跟着叔叔在风波浪涛中淘海为生。当过童养媳,放过牛羊,后来,又随着逃荒大军躲过日本鬼子的炮火,跋涉过万水千山。看手掌上的每一朵茧花,脚板上的每一道裂痕,无不在诉说着生命的艰辛和苦难。    

  (7)倏忽,脚踝上一道长长的伤疤,如同一团火焰灼亮了我的眼睛。记得我考上中学那年,大哥正在读大学,弟妹又小,这对勉强糊口的我们家来说,无疑是雪上加霜。“再苦,孩子的书一定要念,我们眼睛瞎,可不能误了孩子的前程。”母亲斩钉截铁的对父亲说。于是父亲风雨无阻地奔波在乡间小路上。母亲更是起三更睡半夜,跑码头,摆地摊,种菜养猪,一有空闲就别了柴刀上山砍柴卖。一天傍晚,刚从溪边码头卸货回来的母亲,顾不上满头汗水,拿起柴刀又要上山去。我忍不住跟了去,母亲去砍一棵高大的木荷树,那树长得东倒西歪的,倒下时,一根粗壮的树丫打在她的脚踝上,顿时鲜血如注……    

  (8)是的,这伤疤将永远被母亲带去了,我轻轻地用湿毛巾擦拭着,泪水又一次模糊了双眼。    

  (9)大姐小心翼翼地揭开母亲身上的蓝布衫,啊,母亲裸露在我们的面前,蜡黄的肌肤,起伏的胸廓,那丰满秀美的曲线哪里去了?母亲说过,我小时像羊羔一样,喜欢跪在地上吃奶,母亲曾很自豪地向左邻右舍夸我,说这孩子将来一定孝顺。作为女儿的我,真的懂孝道,真的孝敬过父母吗?“古来父母多痴心!”母亲,世上所有的母亲,都曾经用自己圣洁的乳汁哺育过子女。那丰满的 * * 却被我们一群兄弟姐妹吸干了,变得那么干瘪、松散,紧紧贴在瘦骨嶙峋的胸脯上,我小时候吃奶,常常顽皮地用乳牙咬着喷香的奶头,让母亲痛的怜爱地拍打着我粉嫩的脸蛋。母亲,还能让我吸一口那甘甜的乳汁,接受一次你怜爱的拍打么? 

  (10)岁月无情,人生如露。母亲静静躺在灵床上。没有花花绿绿的贡品,没有凄凄惨惨的挽联,甚至不敢大放悲声。佛云,悲啼会使死者的灵魂贪恋尘世,进不了圣洁的天国。眼前唯有三炷清香,一缕若有若无的诵经声,和着两行无声的泪。但人又怎能不依恋尘世?回望生命的轨迹,无论甘甜还是艰辛,不值得回味、眷恋吗? 

  (11)我慢慢地跪下去,跪在母亲身旁,泪水滑过她的胸脯。母亲即将去那矻矻(kūkū:勤劳不懈的样子)追求了一生的净土,此时此刻,我们在为她作最后一次梳洗,尽最后一次孝心。 

1.下列对文章有关内容的理解和分析,不正确的两项是( )

A.第(9)段写为母亲洗身,段末的问句实际上表达了希望能再次享受母亲的温存、抚爱的愿望。

B.第(11)段通过“跪下去”“泪水滑过她的胸脯”的细节描写,表达了“我”对母亲的感激、眷恋与负疚,深化了文章主旨。

C. 文章不事张扬,不事浮华,语句流畅,语调轻快;但感情真挚,字里行间流露出对母亲深深的敬意和诚挚的怀念。

D.文章所说的母亲“矻矻追求了一生的净土”,指的是不用忙忙碌碌、辛勤劳作,却能吃饱穿暖,且到平平安安的生活境地。 E.唐代诗人孟郊诗云:“谁言寸草心,报得三春晖?”作者这篇文章所记所叙完全可以看作是对孟郊这两句诗的诠释。

2.请用简短的语言写出第(2)段“眼皮微微闭合着,嘴角含着一朵淡淡笑容,仿佛刚刚睡去”一句所蕴含的意味。

答:_______________________________________________

3.文章巧妙地勾勒了母亲的生命轨迹,请用简洁的语言分析母亲的形象。  

答:_______________________________________________

4.请从组织材料的线索、顺序方面对文本进行简要赏析。

答:_______________________________________________

You hear the comment all the time: the U.S. economy looks good by figures, but it doesn’t feel good. Why doesn’t ever-greater wealth promote ever-greater happiness? It is a question that dates at least to the appearance in 1958 of The Wealthy Society by John Kenneth Galbraith, who died recently at 97.

The Wealthy Society is a modern classic because it helped describe a new moment in the human condition. For most of history, “hunger, sickness, and cold” threatened nearly everyone, Galbraith wrote. “Poverty (贫穷) was found everywhere in that world. Obviously it is not of ours.” After World War II, the fear of another Great Depression gave way to an economic growth. In the 1930s unemployment had averaged 18.2 percent; in the 1950s it was 4.5 percent.

To Galbraith, materialism (物质主义) had gone mad and would cause discontent. Through advertising, companies conditioned consumers to buy things they didn’t really want or need. Because so much spending was artificial, it would be unsatisfying. Meanwhile, government spending that would make everyone better off was being cut down because people wrongly considered government only as “a necessary bad.”

It’s often said that only the rich are getting ahead; everyone else is standing still or falling behind. Well, there are many undeserving rich — overpaid chief managers, for instance. But over any meaningful period, most people’s incomes are increasing. From 1995 to 2004, people feel “squeezed” because their rising incomes often don’t satisfy their rising wants — for bigger homes, more health care, more education, and faster Internet connections.

The other great disappointment is that it has not got rid of insecurity. People regard job stability as part of their standard of living. As company unemployment increased, that part has gradually become weaker. More workers fear they’ve become “the disposable American,” as Louis Uchitelle puts it in his book by the same name.

Because so much previous suffering and social conflict resulted from poverty, the arrival of widespread wealth suggested utopian (乌托邦式的) possibilities. Up to a point, wealth succeeds. There is much less physical suffering than before. People are better off. Unfortunately, wealth also creates new complaints.

Advanced societies need economic growth to satisfy the multiplying wants of their citizens. But the search for growth cause new anxieties and economic conflicts that disturb the social order. Wealth sets free the individual, promising that everyone can choose a unique way to self-accomplishment. But the promise is so unreasonable that it leads to many disappointments and sometimes inspires choices that have anti-social consequences, including family breakdown. Figures indicate that happiness has not risen with incomes.

Should we be surprised? Not really. We’ve simply confirmed an old truth: the seeking of wealth does not always end with happiness.
