阅读下文,完成下列小题。

渴望倾听

马亚伟

    ①看过一篇小说,大概意思是说:有一个人和别人打赌,把自己关在一间屋子里,如果他能在十年间不和外界有任何接触,就可以赢得一笔巨款。于是,他开始了一个人的幽居生活。熬过了漫长的十年,最后,他终于坚持到约定的期限。但是,他却放弃了巨款,悄然离开。只留下一封信。信中说,十年来,他饱尝了孤独的痛苦,寂寞的摧残。他悟出了一个道理:人拥有比金钱更为重要的东西,那就是感情交流。于是,他重新融入人群,开始新的生活。

    ②可以想象,一个人的幽居一定会如同在沙漠中独行,满目荒凉和绝望,内心巨大的空洞会把人吞噬掉。人生存的精神支柱,人最殷切的愿望,应该是在与别人的交流中获取丰富的生活体验,从中收获情感的源泉。

    ③与人交流,人生码头才会百舸千帆,丰富多彩。

    ④也听说过不同领域的一些艺术大师离群索居,进行艺术创作。可是,再孤独的创作,也需要与欣赏者沟通。梵高、卡夫卡,这些人有着超越时代的艺术才华,他们的作品都是在他们去世后才引起了轰动。其实,只是上帝开了一个玩笑,让他们提前很多年来到这个世界,让他们以一种特立独行的姿态寂寞地面对世人。不过,他们孤独地创作不息,正是因为他们要宣泄,要表达,要沟通,要交流。因为他们知道,一定会有一颗虔诚的灵魂聆听他们的独吟、呐喊、甚至咆哮。总会有人听懂他们,即使是很多年以后。

    ⑤古人遁隐田园山林,与嘈杂的红尘隔绝,与污浊的官场隔绝,可并不是和人隔绝。陶渊明隐居后,还会和农民一起其乐融融地劳作,“日入相与归,壶浆劳芳邻”。孟浩然喜欢田园生活,闲暇时,他会和农人一起“把酒话桑麻”。王维一个人独往于山林中,偶然遇到个林中的老翁,还会“谈笑无还期”。

    ⑥沟通交流是每个人的愿望。即便鲁滨逊漂流到孤岛上,尚且需要一个“星期五”来作伴。

    ⑦我们平凡百姓,更加需要与人沟通交流。一颗孤独的灵魂不能走得很久很远。漫长的人生旅途中,一个人的行走,没有人扶持关照,我们的脚步会沉重如铅,一个人的空间,也必定狭小如囚笼。

    ⑧正是因为人类沟通交流的愿望如此强烈,通讯技术才得以飞速发展。时至今日,我们已经有了很多极为便捷的交流方式和途径。人与人之间的距离越来越小。

    ⑨每一颗心都渴望倾听。让我们搭建一个心灵的城堡,倾听每一颗心的跳动,为自己,为他人。

根据短文理解,完成下列表格。

    Jane was on her way home at around 6 o'clock. It was getting dark. As she drove into her community, she noticed a man.

    She saw the man walking along the sidewalk next to some houses. He didn't live in any of those houses. She had seen this man several times before. He looked like a criminal (罪犯).

    She drove by him. He looked at her car as she drove by. She continued driving and watched him in her rear view mirror (后视镜). She got to the corner and stopped. She continued to watch him walking in her direction. Suddenly, he turned left up a driveway (车道). A red SUV was parked in the driveway right next to the sidewalk. She saw him walk up to the driver's door and put his hand on the handle (把手). Then he returned to the sidewalk and went on to walk in her direction.

    "What is that all about?" Jane wondered. Then she realized that he had tested the door to see if it was locked. "He is a criminal," she thought. "That's what he does. He just walks in our neighborhood looking for cars to break into."

    She called the police and described the man. The police officer said he knew who the man was. The people in the community called two or three times this week to report him walking by. But the police couldn't arrest him for walking around unless they caught him with stolen things. "But he was testing that SUV door to see if it was unlocked," she said.

    "I'm sorry," said the officer. "That's not against the law. If you see him actually steal something, please give us a call."
