米

赵新

    和其他主食比起来,米饭,我是天天吃顿顿吃也吃不烦吃不厌,媳妇叫我“米虫子”。可是有一个问题很是让我添堵:米里的沙子太多,吃饭时总是硌牙,碗里像有炸弹似的,吃得小心翼翼,吃得提心吊胆,吃着吃着就吃出一肚子火,扔下饭碗了事!

    下顿饭还是这样。

    我非常想买些不带沙子的米,吃个放心,吃个坦然,吃个舒畅,吃个欢喜。

    有一天单位组织下乡,先到了某个县城,又从这个县城下到了某个乡镇。这个镇子很大,恰逢集日,街市上人山人海,叫买叫卖,非常热闹。

    我在农贸市场挤挤碰碰地转悠时,看见一个老汉蹲在那里卖米。那米雪白晶莹,幽幽地闪着光,颗颗晶莹剔透,玲珑如玉。

    弯下腰细看细瞅细挑,没有一粒沙子。

    戴上花镜再看再瞅再挑,还是没有沙子。

    请了几个也一起挑米的人帮着看,仍然没有沙子。

    我既兴奋又激动,忙问这米怎么卖。老汉郑重其事地报了价,并且申明这米是他自家产的,价钱虽然偏高了些,却配得上米的品质。

    老汉问我要多少,我说:“豁出去,要100斤!”

    老汉很严肃地说:“同志,我这人光明正大,不遮不瞒,不欺不诈,你要100斤,我只能给你98斤。”

    我说:“老哥,别呀,2斤米也能做好几顿饭呢!”

    老汉顺手提过旁边的一条口袋说:“分量保证给够你,另外2斤就是这里边装着的沙子。”

    我大吃一惊:“沙子?”

    老汉平静如水:“沙子。”

    我一看,那沙子也是米粒般大小,雪白晶莹,幽幽地闪着光,颗颗晶莹剔透,玲珑如玉。如果把这样的沙子和米混在一起,肉眼凡胎,断然看不出来。

    我说:“老哥,我只要米不要沙子。”

    老汉很憨厚地笑了:“同志,对不起,那我这米不卖。”

    我说:“不卖?那你咋不把沙子掺到米里?”

    他说:“那不是坑人吗?”

    我说:“你这也是坑人呀!”

    他说:“这坑和那坑可不一样。这坑是明着坑,是‘姜太公钓鱼,愿者上钩’,我问心无愧;那坑是暗里坑,我怕有人骂我坏了良心,掘我家的祖坟!”

    想想是这么个理,人家叫明唱响了,你完全可以不买嘛。又往深刻之处一想,就觉得这老汉很老实很厚道很可爱了。

    真的就是真的,假的就是假的,他不搞惟妙惟肖的伪装,不做浑水摸鱼的手脚。

    老汉60岁左右,一张皱纹纵横的脸,一双结满老茧的手,嘴唇上的胡须里还有一粒黄色的饭渣。他的鞋破了,露出半个脚趾头。

    我说:“老哥,这米我买。”随即给了他100斤大米的钱,要了他98斤的米。

    老汉拉住我的手:“同志,你先别走,你还没要我那2斤沙子哩。”

    我说:“我不要你的沙子!”

    老汉把钱退给我:“你不要沙子,就把大米还给我,我不贪这份便宜!”

    我愣了,心想,这人真是有脾气,不要他的沙子他还不依!

    老汉说:“我的沙子也是钱,那是经过加工的;你拿回城里种花养草,喂鸟养鱼,比大米用处还大哩。”

    看着他固执认真的样子,我要了他那2斤沙子。

    午饭以后我又来到集市上闲逛,走到卖米老汉那里,看见有好几个人把他抓住,正推推搡搡地押着他在街上走。秋风萧瑟,黄叶飘零,那老汉的脚步踉踉跄跄,落下一路汗腥。

    押着他的人愤怒地斥责:“光天化日之下,你竟敢明目张胆地坑害顾客,让人家买你的沙子!”又一个说:“你把那沙子掺和到米里卖,不就没事了吗?”

    Global Positioning System (GPS) is now a part of everyday driving in many countries. It is a space-based system that provides position and time information in all weather conditions. GPS can help people get to where they want to go.____When this happens, the driver is often to blame. Sometimes a GPS error is responsible. Most often, it is a combination of the two.

    ____Barry Brown, a GPS technologist, took an incident as an example. His friend once flew to an airport in the eastern United States. There he borrowed a GPS-equipped car to use. He wrongly plugged in the home address in the west. It wasn't until he was driving for thirty minutes that he realized it. Mr. Brown says this is a common human error. But he says, “One problem is that GPS has a very small screen and it can just tell you the next turn.____”

    “The Normal and Natural Troubles of Driving with GPS” lists several areas where GPS can cause difficulties. They include maps that are outdated, incorrect or difficult to understand. ____GPS may fail due to these reasons and then lead to confusion for the drivers.

    Although GPS sometimes causes difficulties when people are driving, the most attractive point of this system is its 100% coverage on the planet. It is important for you to have to know what you are doing when you use GPS. You need to have the “ability” to be able to use GPS because it sometimes goes wrong.____

A. There are quite a few situations showing the problems of using GPS.

B. That means that it is not really telling you about going to the wrong place.

C. This space-based system is an important tool for civil and commercial users.

D. But sometimes it sends you to the wrong place or leaves you completely lost.

E. They also contain timing problems related to when GPS commands are given.

F. Advances in technology play an active role in modernizing GPS in many ways.

G. To make GPS well used, you need a good understanding of how drivers and GPS work.
