切梦刀

李健吾

  不知道什么一个机会,也许由于沦陷期间闷居无聊,一个人在街上踽踽而行,忽然来到一个旧书摊头,在靠外的角落,随时有被人踩的可能,赫然露出一部旧书,题签上印着《增广切梦刀》。

  梦而可切,这把刀可谓锋利无比了。

  一个白天黑夜全不做梦的人,一定是一个了不起的勇士。能够做到这步田地的,勇士两个字当之无愧,我们常人没有福分妄想这种称谓,因为一方面必须达观如哲学家,一方面又必须浑浑噩噩如二愣子。

  当然,这部小书是为我们常人做的,作者是一位有心人,愿意将他那把得心应手的快刀送给我们这些太多了梦的可怜虫。我怀着一种欣喜的心情,用我的如获至宝的手轻轻翻开它的皱卷的薄纸。

  原来这是一部详梦的伟著,民国六年问世,才不过二十几个年头,便和秋叶一样凋落在这无人过问的闹市,成为梦的笑柄。这美丽的引人遐想的书名,采取的是《晋书》关于王浚的一个典故。

  “浚夜梦悬三刀于卧屋梁上,须臾又益一刀,浚惊觉,意甚恶之。主簿 李毅再拜贺曰:三刀为州字,又益一者,明府其监益州乎?及贼张弘杀益州刺史皇甫晏,果迁浚为益州刺史。”

  在这小小得意的故事之中,有刀也在梦里,我抱着一腔的奢望惘然如有所失了。

  梦和生命一同存在。它停在记忆的暖室,有情感加以育养:理智旺盛的时候,我以为我可以像如来那样摆脱一切挂恋,把无情的超自然的智慧磨成其快无比的利刃,然而当我这个凡人硬起 心肠照准了往下切的时候,它就如诗人所咏的东流水,初是奋然,竟是徒然:

  “抽刀断水水更流。”

  有的时候,那就糟透了,受伤的是我自己,不是水:

  “磨刀呜咽水, 水赤刃伤手。”

  于是,我学了一个乖,不再从笨拙的截击上下工夫,因为那样做的结果,固然梦可以不存在了,犹如一切苦行僧,生命本身也就不复在人世存在了,我把自然还给我的梦,梦拿亲切送我做报答。我活着的勇气,一半从理想里提取,一半却从人情里得到。而理想和人情是我梦的弼辅。说到这里,严酷的父亲,在我十三岁上就为人杀害了的父亲,可怜的辛劳的父亲,在我的梦里永远拿一个笑脸给他永远没有出息的孩子。我可怜的姐姐,我就那么一位姐姐,小时候我曾拿剪刀戳破她的手,叫她哭,还不许她告诉父亲,但是为了爱护,她永远不要别人有一点点伤害我,就是这样一位母亲一样的姐姐,终于很早就丢下我去向父亲诉苦,一个孤女的流落的忧苦。他们活着……全都活着,活在我的梦里… …还有我那苦难的祖国,人民甘愿为她吃苦,然而胜利来了,就没有一天幸福还给人民……也成了梦。

  先生,你有一把切梦刀吗?

  把噩梦给我切掉,那些把希望变成失望的事实,那些从小到大的折磨的痕迹,那些让爱情成为仇恨的种子,先生,你好不好送我一把刀全切了下去?你摇头。你的意思是说,没有痛苦,幸福永远不会完整。梦是奋斗的最深的动力。

  那么,卖旧书的人,这部《切梦刀》真就有什么用处,你为什么不留着,留着给自己使用?你把它扔在街头,夹杂在其他旧书之中,由人翻拣,听人踩压,是不是因为你已经学会了所有的窍门,用不着它随时指点?

  那边来了一个买主。

  “几钿?”

  “五百。”

  “贵来!”他惘惘然而去。 

  可怜的老头,《切梦刀》帮不了你的忙,我听见你的沙哑的喉咙在吼号,还在叹息:“五百,两套烧饼啊!” (文章有删节)

1.以“理想和人情”为“弼辅”的“梦”,在文中具体指哪些内容?

                                                                                                                                                            

                                                                                                                                                            

2.作者赋予了“切梦刀”怎样的含义?请根据文意加以阐释。

                                                                                                                                                            

                                                                                                                                                            

3.文中写到“姐姐”的死,没有直接用“去世”等字眼儿描述,这表达了“我”怎样的情感?请简要赏析。

                                                                                                                                                            

                                                                                                                                                             

4.如果将文章最后一段删去,好不好?为什么?

题型:单项选择题

Compared with IBM, Microsoft is a mere young company. Founded in 1975, it rose swiftly to dominate the world of personal computing with its Windows operating system and Office suite of word-processing and other productivity tools. But the company is now showing some worrying signs of middle-age fatigue. In particular, it is struggling to find a growth strategy that will enthuse disappointed shareholders.

Complaint are understandable. Since Steve Ballmer took over from Bill Gates as chief executive in 2000, Microsoft’s share price has decreased and the company has lost its reputation as a tech trend-setter. It has been left behind in hot areas such as search and social networking by younger companies, some of which love to thumb their noses at their older rival. Eric Schmidt, the executive chairman of Google, recently proclaimed that leadership in the tech world had passed from Microsoft and others to a "Gang of Four" fast-growing, consumer-oriented businesses: Google, Apple, Amazon and Facebook.

Few would object to that. The question is: what,if anything, can Microsoft do to change it In at least some respects, the company appears to be suffering from similar ailments to those that laid IBM low before Lou Gerstner was hired in 1993 to get it back on its feet. These include arrogance bred of dominance of a particular area-mainframe computers at IBM, personal computers at Microsoft—and internal fiefs that hamper swift change.

As IBM’s experience shows, recovery in the tech world is possible. And some observers see encouraging signs of progress at Microsoft. Sarah Rotman Epps of Forrester, a research firm, reckons that Windows 8, a forthcoming version of Microsoft’s operating system, could be a serious competitor to Google’s Android on tablet computers if the company can get it to market next year.Microsoft is also in far better shape financially than IBM was at its lowest point, so it can afford to splash out on acquisitions such as its recent $8.5 billion purchase of Skype, an internet-phone and video-calling service.

That bet and an alliance with Nokia in mobile phones show that Microsoft is trying to bulk up in promising areas. Yet sceptics worry that such initiatives are not the product of an comprehensive strategic vision, but are instead temporary moves designed to calm critics who fear Microsoft is drifting downwards. David Einhorn, a prominent hedge-fund manager whose fund holds shares in Microsoft, has publicly called for a change at the top of the firm, arguing that Mr Ballmer is "stuck in the past". So far, the company’s board, chaired by Mr Gates, has backed its chief executive. But if IBM’s history is a guide, Microsoft may yet end up jettisoning its leader.

According to the text, Microsoft’s younger competitors ()

A. will prevail over Microsoft

B. challenge Microsoft’s prestige

C. bring down Microsoft’s share price

D. show contempt for Microsoft
