躲在书后面的孙犁

舒乙

  作家不必像演员,尤其不必像明星。作家的名字可以很响亮;但是读者不认识他们,没见过他们,不知道他们长什么样。他们有名,是他们的作品频繁地在杂志上、报纸上、书上出现。

  作家是躲在书后面的人。最典型的要数孙犁先生。

  孙犁从不出席各种热闹场合,甚至害怕照相。他是真正的深居简出。没见过新闻报道中出现过孙犁的名字,因为他拒不出席各类活动,整天整天地躲在家里写东西,频频地发表作品。这才是孙犁。晚年,到了实在不能写的时候,孙犁甚至不说话了。在病床上,他头脑清晰,但极少说话。在住院之前,差不多在20年里,孙犁连续写了10本新书!为这10本书,我参加过一次在“三联韬奋书店”举行的研讨会。与会者都为他复出后的高产而惊叹。晚年,他的文章越写越短,却居然写了10本。

  中国优秀的老作家有一个特点,晚年复出后又掀起一个写作高潮,巴老如此,冰心如此,萧乾如此,孙犁也如此。因为写得好,这次高潮构成了他们一生中的第二个高峰,一点不弱于《家》、《寄小读者》或者《荷花淀》。

  孙犁的《荷花淀》和《铁木前传》莫定了他是中国现代文学大师级的作家地位。但是,他晚年的这10本书,却让我们看见了一个更加丰富多彩的伟人级的作家。

  躲在这10本书后面的孙犁是一个心地善良、目光犀利、襟怀坦荡、敢说敢为、嫉恶如仇的真君子。他很像一座浮出海面的冰山,不显山,不显水,平平静静,安安稳稳;可哪知道,海面之下竟是那么庞大,那么威严,那么厚重,也那么厉害。这种厉害,是一种痛快,一种淋漓尽致,一种不隐讳,一种一针见血。念孙犁的文章就有了一种难得的对他的崇敬感,因为他敢讲真话,敢抒己见,敢一语道破。于是躲在书后面的孙犁一下子就成了一座大山,巍峨的大山。你也因此而明白,他为什么不爱出头露面,不爱上镜,不爱出席公众场合。只因他不爱掩饰自己的观点。

  孙犁,应该说,是中国最有学问的作家之一。他拥有大量的书,他念过大量的书。孙犁爱书如命。他爱书,爱寻书,爱买书,爱藏书,爱念书,爱谈书。更有甚者,他爱给书籍包书皮,打扮书,包装书,都亲手做。他还爱在书上题词,写好多话,信手写来,皆成文章。这样的书,是他的宝,也是他的象征,在众多的作家中,在这方面他是独一无二的,堪称冠军。

  中国现代文学馆多次派人去拜访孙犁先生,去看他这些可爱的书,后来又去和孙家子女谈这些书的归宿和“孙犁文库”的未来。这些书上有孙犁的手艺,有孙犁的笔迹,有孙犁的思想,有孙犁的感情。它们是孙犁,孙犁是它们。必须善待这些书。未来的“孙犁文库”就是“孙犁博物馆”,是一个最有特色的中国现代文人的纪念馆。一旦成立起来,肯定,它最有中国文人味儿,既有文献性,也具有极大的启示性。

  想一想,一个解放区来的作家,一个南征北战的人,一个写过那么美的传世作品的人,一个紧跟时代步伐的人,一个极有学问的人,一个惜书如命的人,放在一起,看似矛质,但确实扎扎实实地集于一身,岂不是天下一大奇观呜。

  有一次,孙犁在他的藏书《西游记》上做了以下的书茂:“淡泊晚年,无竞无争,抱残守缺,以安以宁。唯对于书,不能忘情。我之于书,爱护备至:污者净之,折者平之,阅前沐手,阅后安置。温公惜书,不过如斯。“勿作书盆,勿为书痴,勿构泥之,勿尽信之。天道多变,有阴有晴;登山涉水,遇雨遇风,物有聚散,时损时增。不以为累,是高水平。”

  这些话,是孙华先生的人生观。是一个大儒的人生观。是一个大作家的人生观。躲在书后的,竟是这么一个伟大的现代人。

  他去世了,可是他的遗产够后人受用很久很久。想着想着,我的心境平静了下来。慢慢地、渐渐地。

(1)下列对传记有关内容的分析和概括,最恰当的两项是(     )

A.“勿作书盆,勿为书痴,勿拘泥之,勿尽信之”,表明孙犁不愿做书蠢、书痴,爱书却不信书,不为书中内容所束缚,有自己独到的见解。

B.孙犁平时不显山,不露水,甚至人们没见过新闻报道中出现过他的名字,除了他整天整天躲在家里写东西之外,更主要是他不喜欢照相。

C.文章写到巴老、冰心和萧乾,一方面衬托孙犁晚年复出后掀起又一写作高潮,暗示其中国现代文学大师级地位;一方面丰富了文章内容。

D.孙犁是一个解放区来的作家,他南征北战,写过那么美的传世作品,紧跟时代步伐,极有学问,惜书如命,他是一个实实在在的矛盾体。

E.文章结尾“我的心境平静了下来。慢慢地、渐渐地”,不仅透露出作者对孙犁先生的崇高敬意,并且暗示了孙犁对浮躁的后辈的巨大影响。

(2)为什么说孙犁是躲在书后面的作家?请简要概括。

_____________________________________________

(3)综观全文,说说躲在书后面的孙犁是个怎样的人?

_____________________________________________

(4)孙犁在他所藏《西游记》的书蔑中写道:“我之于书,爱护备至:污者净之,折者平之,阅前沐手,阅后安置。……勿作书蠢,勿为书痴。……不以为累,是高水平。”孙老先生爱书可见一斑。你对此有什么认识?请结合文本谈谈你的读书观。

It seems that many college graduates are unsure of what to do with their lives, so they jump back into the college scene by default(违约). But graduate school is costly, time consuming and requires a lot of in-depth study, and also parents will lay down more money and banks will supply more student loans.

However, there are some students who should be pursuing graduate degrees. Teachers, lawyers, doctors, professors and ministers are a few examples of those who will benefit from class work past a bachelor’s degree. Their professions call for additional courses and more specialization and therefore higher education is a must. Still, all students in general should not adopt the idea that graduate school is necessary for individuals who want to make more money. Working hard right after college can lead to promotions in the future. It seems that it does more good to network or internship(实习)with professionals while pursing a bachelor’s degree than it does to complete a master’s and distant oneself from the world of work.

If a student graduates with a four-year degree and immediately enters the work force , he will most likely start an entry-level pay. In a couple of years this employee will gain seniority and experience, therefore increasing their chance for pay rise. He will learn the information at his job-site that he did not learn in school. His bachelor’s degree loan can be immediately chipped away ,and his maturity level can increase as real work related responsibilities set in. But, if the student pursues a master’s degree, he may be able to demand more pay initially when he finally goes job hunting, but years of serious money making as well as work experience will already be lost.

Students should not shy from the workforce just because uncertainty follows graduation. Those who pursue a graduate degree just because they do not want to leave school and because they view the “real world” as scary should think again. Using graduate studies as a hiding place from the full-time job is a waste of time.
