把玉米变成黄金

感动

  考泽是美国艾奥瓦州的农民,和美国西部其他农民一样,考泽主要以种植玉米为生。虽然美国是发达国家,但种田的农民也是很艰辛的。为了有个好收成,考泽要像照顾孩子一样伺候自己的庄稼,年复一年,他在田垄里风里来,雨里去,常常是落得一身泥巴点,累得佝了腰,生活却没有什么变化。

  种玉米,卖玉米,再种玉米,再卖玉米,几十年来,考泽一直在农田里重复着这个周而复始的轮回,每年秋收,考泽总会出神地看着那些堆积如山的玉米,那时,他常常幻想着这些金黄色的玉米会变成金灿灿的黄金。

  玉米作为一种普通的粮食,它的价格是最低廉的,这是小孩子都知道的道理,但考泽却不这样认为。他在那些玉米中捕捉着灵感,寻找着希望。他相信,那些玉米颗粒中一定潜藏着人们未发现的价值,如果改变玉米的命运,就会改变自己的命运。

  考泽开始查阅有关玉米的各种资料,有一天,考泽在互联网上偶尔看到一则消息:德国和日本生产出了燃烧乙醇的汽车。他立刻把这条消息和玉米联系在了一起,当时,人们意识中的玉米只是一种粮食,没有人想到蕴藏在玉米中的乙醇,是可再生的能源。但考泽却产生了用玉米来加工乙醇的念头。考泽还了解到,石油资源的逐年减少,导致国际原油价格的逐年上涨,这使各国对能源的争夺越来越激烈,人类迫切需要一种新的能源。用玉米来加工出乙醇将会是一种新的能源获得方式。

  新的发现让考泽兴奋不已,他找到周围的其他农民,希望他们能和自己一道来实现这一梦想。但是,很多农民听了之后都认为不可行,因为他们认为玉米里根本不可能产生汽车的燃料。考泽后来找到了一家科研机构商谈合作事宜,结果机构的负责人对考泽的想法很感兴趣。于是,他们和考泽共同成立了林肯威能源公司。2006年5月,林肯威能源公司开始利用玉米来生产乙醇汽油。玉米脱胎换骨为乙醇汽油后,其附加值开始成倍增长,考泽那个玉米变黄金的愿望终于成为现实。

  因为乙醇既可以减少温室气体,又可减少美国对外国石油的依赖,所以,玉米提炼乙醇将成为解决美国能源饥渴的新的办法之一。凭着这种创新,农民考泽成为美国《时代》杂志评出的2006年度最具影响力人物之一。

  《时代》杂志对他的评价是,这个农民,依靠智慧的魔法,把普通的玉米变成了“黄金”。

     Psychologists tell us that there are four basic stages that human beings pass through when they enter

and live in a new culture. This process, which helps us to deal with culture shock, is the way our brain

and our personality react to the strange new things we encounter when we move from one culture to

another.

     Culture begins with the "honeymoon stage".  1 _____. We are thrilled to be in the new environment,

seeing new sights, hearing new sounds and language, eating new kinds of food. 2_____.

     3______. After we have settled down into our new life, we can become very tired and begin to miss

our homeland and our family, friends, pets. All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture. This period of cultural adjustment can be very difficult

and lead to the new arrival rejecting or pulling away from the new culture.

     The third stage is called the "adjustment stage". 4_____. Your sense of humour usually becomes

stronger and you realize that you are becoming stronger by learning to take care of yourself in the new

place. Things are still difficult, but you are now a survivor!

     The fourth stage can be called "at ease at last". Now you feel quite comfortable in your new

surroundings. 5_____. You may still have problems with the language, but you know you are strong

enough to deal with them.

A.You can cope with most problems that occur.

B.This is when you begin to realize that things are not so bad in the host culture.

C. It is extremely difficult to get through the first stage of culture.

D. You may feel sad, anxious, frustrated, and want to go home.

E. Unfortunately, the second stage can be more difficult.

F. This stage can last for quite a long time because we feel we are involved in some kind of great

adventure.

G.This is the period of time when we first arrive in which everything about the new culture is strange and

exciting.
