现代文阅读（26分）

有一天，我在家听到打门，开门看见老王直僵僵地镶嵌在门框里。往常他坐在蹬三轮的座上，或抱着冰伛着身子进我家来，不显得那么高。也许他平时不那么瘦，也不那么直僵僵的。他面如死灰，两只眼上都结着一层翳，分不清哪一只瞎，哪一只不瞎。说得可笑些，他简直像棺材里倒出来的，就像我想像里的僵尸，骷髅上绷着一层枯黄的干皮，打上一棍就会散成一堆白骨。我吃惊地说：“啊呀，老王，你好些了吗?”

他“嗯”了一声，直着脚往里走，对我伸出两手。他一手提着个瓶子，一手提着一包东西。

我忙去接。瓶子里是香油，包裹里是鸡蛋。我记不清是十个还是二十个，因为在我记忆里多得数不完。我也记不起他是怎么说的，反正意思很明白，那是他送我们的。

我强笑说：“老王，这么新鲜的大鸡蛋，都给我们吃?”

他只说：“我不吃。”

我谢了他的好香油，谢了他的大鸡蛋，然后转身进屋去。他赶忙止住我说：“我不是要钱。”

我也赶忙解释：“我知道，我知道——不过你既然来了，就免得托人捎了。”

他也许觉得我这话有理，站着等我。  

我把他包鸡蛋的一方灰不灰、蓝不蓝的方格子破布叠好还他。他一手拿着布，一手攥着钱，滞笨地转过身子。我忙去给他开了门，站在楼梯口，看他直着脚要一级一级下楼去，直担心他半楼梯摔倒。等到听不见脚步声，我回屋才感到抱歉，没请他坐坐喝口茶水。可是我害怕得糊涂了。那直僵僵的身体好像不能坐，稍一弯曲就会散成一堆骨头。我不能想像他是怎么回家的。

     Humor is a most effective, yet frequently neglected, means of handling the difficult situations in our lives.

It can be used for patching up differences, apologizing, saying "no," criticizing, getting the other fellow to do

what you want without his losing face. For some jobs, it's the only tool that can succeed. It is a way to discuss

subjects so sensitive that serious dialogue may start a quarrel. For example, many believe that comedians on

television are doing more today for racial and religious tolerance than people in any other forum. 

     Humor is often the best way to keep a small misunderstanding from escalating into a big deal. Recently a

neighbor of mine had a squabble with his wife as she drove him to the airport. Airborne, he felt miserable, and

he knew she did, too. Two hours after she returned home, she received a long-distance phone call. "person-to-

person for Mrs. I.A. Pologize," intoned the operator. "That's spelled 'P' as in…". In a twinkling, the whole day

changed from grim to lovely at both ends of the wire. 

     An English hostess with a quick wit was giving a formal dinner for eight distinguished guests whom she

hoped to enlist in a major charity drive. Austerity (节俭) was a fashion in England at the time, and she had

asked her children to serve the meal. She knew that anything could happen-and it did, just as her son, with the

studied concentration of a tightrope walker, brought in a large roast turkey. He successfully elbowed the

swinging dining-room door, but the backswing threw the bird onto the dining-room floor. 

     The boy stood rooted: guests stared at their plates. Moving only her head the hostess smiled at her son,

"No harm, Daniel," she said. "Just pick him up and take him back to the kitchen"… she enunciated clearly so

he would think about what she was saying …"and bring in the other one ."

     A wink and a one-liner instantly changed the dinner from a red-faced embarrassment to a conspiracy of fun.
