打（17分）

阎连科

（1）我每每想起我父亲，都是从他对我的痛打开始的。

（2）我记得的第一次痛打是我七八岁的当儿。那时候，每年的春节之前，父亲都会千方百计存下几块钱，换成一沓儿簇新的一角的毛票，放在他的苇席下，待到了初一那天，发给他的儿女和正月来走亲戚的孩娃们。可是那一年，父亲要给大家发钱时，那几十上百张一毛的票儿却没有几张了。那一年，我很早就发现那苇席下藏有新的毛票儿。每天上学时，我总是从那席下偷偷地抽走一张，在路上买一个烧饼吃。

（3）从初一到初五，父亲没有给我脸色看，更没有打我和骂我，他待我如往年无二，让我高高兴兴过完了一个春节。可到了初六，父亲问我偷钱没有。我说没有，父亲便厉声让我跪下了。反复问我偷没有，我都说没有，父亲便狠力地朝我脸上掴起耳光来。我的脸又热又痛，到了实在不能忍了，我才说那钱确是我偷的，全都买了烧饼吃掉了。然后，父亲就不再说啥儿，把他的头扭到一边去。不看我，可等他再扭头回来时，我看见他眼里含着的泪。【批注：一个“扭”，是父亲下意识的掩饰，但“眼里含着的泪”让我们窥见他严厉外表下的内心世界，那时对儿子的心疼，也有一个父亲无奈的辛酸。】

（4）第二次，仍是在我十岁之前，我和几个同学到人家地里偷黄瓜。仅仅因为偷黄瓜，父亲也许不会打我的。主要是因为我们其中还有人偷了人家那一季卖黄瓜的钱。那钱是人家一年的口粮，不把钱还给人家，人家一家就无法度过那年的日子。

（5）父亲知道后，也许认定那钱是我偷的，毕竟我有前科。他让我跪在院落的一块石板地上，先噼里啪啦把我痛打一顿后，才问我偷了人家的钱没有。我说没有，父亲就又噼里啪啦地朝我脸上打，直打得他没有力气了，才坐下直盯盯地望着我。那一次，我的脸肿了。因为心里委屈，夜饭没吃，我便早早地上了床去。睡到半夜父亲却把我摇醒，好像求我一样问：“你真的没拿人家的钱？”我朝父亲点了一下头。然后然后父亲就拿手去我脸上轻轻摸了摸，又把他的脸扭到一边，看着窗外的夜色和月光。一会儿他就出去了，坐在院落里，孤零零地坐在我跪过的石板地上的一张凳子上，望着天空，让夜露潮润着，直到我又睡了一觉起床小解，父亲还在那儿静静地坐着没有动。

（6）第三次，父亲是最最应该打我的，应该把我打得鼻青脸肿、头破血流的，可是父亲没打我。那时我已经十几岁。到乡公所里去玩耍，看见一个乡干部屋里的窗台上，放着一个精美铝盒的刮脸刀，我便把手从窗缝伸进去，把那刮脸刀盒偷出来，回去对我父亲说，我在路上拾了一个刮脸刀。

（7）父亲不是一个刨根问底的人，我也不再是一个单纯素洁的乡村孩子了。到后来，那个刮脸刀，父亲就长长久久地用将下来了。每隔三朝两日，我看见父亲对着刮脸刀里的小镜刮脸时，心里就特别温暖和舒展，好像那是我买给父亲的礼物一样。多年后，我当兵回家休假时，看见病中的父亲还在用着那个刮脸刀架在刮脸，心里才有一丝说不清的酸楚升上来。我对父亲说：“这刮脸刀你用了十多年，下次回来我给你捎一个新的吧。”父亲说：“不用，还好哩，结实呢，我死了这刀架也还用不坏。”

（8）听到这儿，我有些想掉泪，也和当年打我的父亲样，把脸扭到了一边去。【批注：          】

（9）两年后，我的父亲病故了。回家安葬完了父亲，收拾他用过的东西时，我看见那个铝盒刮脸刀静静地放在我家的窗台上，黄漆脱得一点都没了，铝盒的白色在锃光发亮地闪耀着。

（10）算到现在，父亲已经离开我二十四五年了。我不停地想念他。而每次想念父亲，又似乎都是从他对我的痛打开始的。我没想到，活到今天，父亲对我的痛打，竟使我那样感到安慰和幸福。可惜的是，父亲最最该痛打、暴打我的那一次，却被我遮掩过去了。而且是时至今日，我都还没有为那次正本真切的偷盗而懊悔。只是觉得，父亲要是在那次我真正的偷盗之后，能再对我有一次痛打就好了。在父亲的一生中，要能再对我痛打十次八次就好了。觉得父亲如果今天还能如往日一样打我骂我，我该有何样的安慰、幸福啊。

In most aspects of medieval life, the closed corporation prevailed. But compared to modern life, the medieval urban family was a very open unit: for it included, as part of the normal household, not only relatives by blood but a group of industrial workers as well as domestics whose relation was that of secondary members of family. This held for all classes, for young men from the upper classes got their knowledge of the world by serving as waiting men in a noble family: what they observed and overheard at mealtime was part of their education. Apprentices lived as members of the master craftsman’s family. If marriage was perhaps deferred longer for men than today, the advantages of home life were not entirely lacking, even for the bachelor.
The workshop was a family; likewise the merchant’s counting house. The members ate together at the same table, worked in the same rooms, slept in the same or common hall, converted at night into dormitories, joined in the family prayers, participated in the common amusements.
The intimate unity of domesticity and labour dictated the major arrangement within the medieval dwelling-house itself. Houses were usually built in continuous rows around the perimeter of their gardens. Freestanding houses, unduly exposed to the elements, wasteful of the land on each side, harder to heat, were relatively scarce: even farmhouses would be part of a solid block that included the stables, barns and granaries. The materials for the houses came out of the local soil, and they varied with the region. Houses in the continuous row forming the closed perimeter of a block, with guarded access on the ground floor, served as a domestic wall: a genuine protection against felonious entry in troubled times.
The earliest houses would have small window openings, with shutters to keep out the weather; then later, permanent windows of oiled cloth, paper and eventually glass. In the fifteenth century, glass, hitherto so costly it was used only for public buildings, became more frequent, at first only in the upper part of the window. A typical sixteenth-century window would have been divided into three panels: the uppermost panel, fixed, would be of diamond-parted glass; the next two panels would have shutters that opened inwards; thus the amount of exposure to sunlight and air could be controlled, yet on inclement days, both sets of shutters could be closed, without altogether shutting out our light. On any consideration of hygiene and ventilation this type of window was superior to the all-glass window that succeeded it, since glass excludes the bactericidal ultra-violet rays.

Where could you have expected to find glass used in the fourteenth century

A. In small windows in private houses.
B. In buildings designed for public use.
C. Forming one part of a window protection.
D. Behind protective shutters.
