阴影与阳光

    14岁的中学生小佳觉得自己这几天倒霉透了。

    前天,因为出黑板报的缘故,他是最后一个离校的学生。黑板报出到一半,突然他想看看高年级黑板报出得怎么样,取取经。但是人家教室门已经锁上了。于是他从自己教室搬来了一张凳子。人站在凳子上,这样他就可以通过墙上气窗,看到人家教室里的黑板报。正在他脸贴玻璃,专心张望的时候,值班老师走了过来,有点狐疑地问了他一番后,就要他赶快回家。巧的是,这天夜里,这一层的办公室遭窃。所有老师的抽屉都被翻动,连零星小钱都被搜走。这样,作为最后一个离校又有点古怪行为的学生,就有理由被唤到教务处谈话。虽然班主任和熟悉他的任课老师全都担保他是个品学兼优的好学生,但是从教务处出来的小佳仍忍不住掉了眼泪,因为班上竟有不明真相的同学,用一种陌生的眼光打量他,包括和他挺好的同学。

    今天的事更是倒霉了。现在他向妈妈哭诉今天的遭遇。放学回家途经一个专卖复习资料的书屋,买了两本书,刚准备跨上自行车时,迎面一辆卡车上突然滚下来一只大纸箱,纸箱破了,里面的儿童玩具散落一地。待车上司机发现,将车停下来时,周围已有人趁机捡了便宜溜走了。他看司机挺急,就帮着司机把玩具一一捡回装进箱子里。好事做完后,他的自行车却不见了!那是才买了不久的新车啊!

    “好心没好报!小偷太坏了!呜呜呜……”小佳边说边哭,眼泪越流越多。

    “哭什么?哭了车子能回来吗?傻瓜!以后一定要接受教训。俗话说,自扫门前雪,莫管他人瓦上霜,是有一定道理的。妈妈不是要你做自私的人,问题是现在风气坏,人心不古,所以要学会保护自己,不要多管闲事,免得招惹是非……”小佳妈妈唠唠叨叨边劝边教训儿子。

    “你在培养儿子朝自私发展吗?”小佳的爸爸从外面踏进门,听到了妻子的话,打趣道。

    “你倒还有精神说笑话,儿子前天为班级做好事,被人疑心当贼,今天做好事,被贼偷了!”

    小佳的妈妈把儿子今天的遭遇愤愤地说给了丈夫,一旁的小佳哭得更厉害了。

    “噢,是这样,儿子,你的运气确实太坏了!爸爸今天的运气倒有点好。你知道的,我是去那家摄影社取照片的,取完照片,回来路上觉得今天天气挺热的,这时有个人用自行车推着两袋西瓜在卖。我挑了一只,过了秤,正好10元钱,我付了钱,骑上车就走。骑了大约20米,忽听背后有人在叫。我回头一看,那个卖西瓜的骑着车子朝我追来,一边招手,一边叫我停。我停了车,才知道原来我错将百元大钞当成10元票给了他,他是来追还我90元钱的!儿子,你想想看,他完全可以不管这件事,要还,等我找上来,也不迟;甚至可以赖掉,因为我没有凭证;还可以发现后马上溜走,不会引起任何纠葛。现在他却冒着烈日,骑着笨重的车子一路追来,为什么要这么做呢?是他的良心!是他做人的道德!谁说这世上没有好人!”

    父亲拍拍刚买来的西瓜,又拍拍儿子的头。儿子停止了抽泣,听得很专注。

    不错,小佳的爸爸是在取了照片后买了西瓜,但是,关于10元与100元的故事,是他的虚构。作家与父亲的双重责任,让他编了个美丽的故事。他深深懂得,此刻,这个14岁少年的心里,太需要阳光。

根据短文内容的理解,选择正确答案。   

    When you cough or sneeze, you'd better turn your head away from others and cover your mouth with the full part of your hand. And then, you should say, "Excuse me."

    This seems so simple, but it is surprising how many kids have never been told to do this. Actually, I notice adults all the time who cough and sneeze in public without placing a hand over the mouth. One important thing I point out to the kids is that after they sneeze or cough on their hands, they should wash their hands as soon as possible. If not, they will be passing those germs (细菌) along to everything and everyone they touch.

 

    If you come to a door and someone is following you, hold the door. If the door opens by pulling, pull it open, stand to the side, and allow the other person to pass through first, then you can walk through. If the door opens by pushing, hold the door after you pass through.

    After a few weeks of seeing kids try to get through doors in the school and watching them enter restaurants as the door hit other people, I knew I had to discuss the problem with my students. Teaching them small acts of kindness, such as letting someone else go through a door first as they hold it open, may seem unimportant, but it can go along way toward helping students realize how to be polite and thank others. Once they've been told, they're halfway there.

    When we have to go up moving stairs, we will stand to the right. That will give others who are in a hurry a choice of walking up the left-hand side of the moving stairs. When we are going to enter a lift, the underground, or a doorway, we will wait for others to exit before we enter.

    After college when I moved to London, I was surprised at how polite everyone was in the subways. I was even more touched when I traveled to Japan. In both places, people made efforts to make way for others. On moving stairs, everyone stood to the right and walked to the left. On lifts, everyone would stand over to the side and allow others to exit before they would begin to enter.
