一杯水的温暖

    这是一天里最热的时段。

    毒辣的日头悬在半空里,炙烤着大院里的一草一花,水泥路白亮亮的,反射着刺眼的光,没有一丝风,没有一个人走动,整个院子像中暑了,蔫头耷脑地躺在烈日下

    谁也没有想到,一辆运水的人力三轮车碾压着自身的影子,踏进院里来了。三轮车摇摇晃晃、吱吱呀呀地行进着,在宿舍楼前停下了。

    车上下来一位中年人,淋漓的汗水漫流在黝黑的脸上,浸湿了上身那件灰色的衬褂。他扯起搭在肩上的毛巾,囫囵擦了一把汗,便从车袋里摸出一个装饮用水的瓶子,摇了摇是空的,就又放回去了。水没喝上,中年人有点失望,但也就是一瞬间,他抬起头,眯着眼望了望,迅即从车上搬起一桶水,扛上肩,往宿舍楼里走去。

    原来,他是来给住在楼里的人家送水的。

    攀上,跨下,中年人搬着一桶又一桶的水往楼里送。几趟下来,他想喝杯水的愿望越来越强烈,可是那些人家都只是从透着冷气的门缝里塞给他五元钱,就让他把水放下了,他连讨杯水的机会都寻不到。总算只剩下一桶水了,并且还是二楼的,他算计着送完这桶水踏着空车回去,顶多半个小时就可以喝上水了。一想到马上有水喝,脚下又有劲了。

    门铃一响,不想这回门全打开了,是一位大妈,看见中年人连声叫道:“哎哟,看把你热的,快进屋来歇歇!”

    中年人放下水,看了看自己的模样,不好意思往屋里走,大妈见状,一把把他拉了进来,光洁的木质地砖上,留下了几个脏兮兮的脚印。

    大妈赶紧挪过一台风扇,凉爽的风顿时源源吹向中年人。

    “师傅,今天怎么是你送的水?”大妈问。

    “听说跑这路的顾不过来,我是他们临时叫来的。”

    “是的,都打电话要水,能顾得过来嘛。”大妈说这话时,已将一杯水递到了中年人面前,可是中年人没有接,问:“大妈,您家有一次性茶杯吗?”

    “……”大妈望着中年人,有些疑惑。

    “大妈,我患过肺结核。”

    一丝黯然从大妈的脸上掠过,随即淡然一笑,说:“不必顾忌,没事的,你快喝吧,是温水。”

    中年人接过水,脖子一仰,干了。一杯温水下肚,他感觉舒坦多了,就返身从门口把水提进来,拆了封,装到饮水机上。大妈也就让中年人帮着装水,等他装好了水,掏出五元钱来给他。中年人收了钱正要离去,大妈又叫住了他,让他等一等。   大妈去房里取回几盒药来,对中年人说:“这是进口药,专治那病的,你拿去问问医生,要是行就服了吧。记着,那病要根治,一旦复发就有些难了……”

    大妈说着说着,声音有些异样,中年人不解地望着大妈,大妈将药塞进他的手里,又说:“拿着吧,我女儿从国外寄来的,都是上好的药,只是……我家老头……他自个耽误了……”

    中年人明白了,心里难过起来,两眼一润,想说些什么,可一时又不知从哪里说起,像个孩子似的站在大妈的面前,好一会才说:“大妈,您老人家今后要是有力气活,就打我电话!”

    踏车回去的时候,中年人感觉腿脚都是劲,日头好像减了几分威力……

同类题3

完形填空

    I was tired and hungry after a long day of work.

    When I walked into the living-room, my 12-year-old son 1 up at me and said, “I love you.” I didn't know what to say. For several 2 all I could do was to 3 there and looked down at him. My first thought was that he must need 4 with his homework or he was trying to 5 me for some news.

    Finally I asked, “What was that all about?”

     “Nothing,” he said. “My teacher said we should 6 our parents that we love them and sees what they say. It's 7.”

    The next day I called his teacher to find out more about this “experiment” and how the other parents had 8.

     “Most of the fathers had the 9 reacting (反应) as you did,” the teacher said. “When I first 10 we try this, I asked the children what they thought their parents would say. Some of them thought their parents would have heart trouble. “The 11 is,” the teacher explained, “feeling loved is an important part of 12. It is something all people 13. What I'm trying to tell the children is that it's too 14 we don't all express those feeling. A boy  is 15 to tell his dad he loves him.”

    The teacher, a middle-aged man, understands how 16 it is for some of us to say the things that would be good for us to say.

    When my son came to me that evening, I held on to (抱着) him for17 second. And just before he 18 away, I said in my deepest, most manly (男子气概) voice, “Hey, I love you, too.”

    I don't know if saying that made either of us healthier, but it did feel pretty good (感觉很好). Maybe next time one of my children says “I love you”, it would  take me a whole 19 to think of the right 20.
