捡垃圾的老外
路乞，英文名K．L．Rothey，今年65岁，现在武汉新东方学校任教。这位美国老头给自己起的中文名叫“路乞”，意思就是“路边的乞丐”。路乞和志愿者所到之处，烟头、废纸等各种垃圾立刻被“请进”垃圾桶，少了它们的“点缀”，道路转眼间变得整洁起来。行走中，一些行人也被他们感染。来市区办事的郭婕，毫不犹豫地加入了捡垃圾的行列……她说：“我真后悔没把女儿带来受受教育。”
路乞说：“我认为捡垃圾的乞丐做的是爱护环境的工作，是很高尚、很重要的工作。”当然，乞丐并不是路乞的职业。退休前，他是一位法律工作者，现在的名片上印着“法学博士”。1984年他第一次因公来到中国，从此对中国文化产生浓厚兴趣，先后来华50余次。去年9月他来到湖北省黄石市，与该市女书法家孟顺波共结连理，定居中国。
居住黄石期间，他走在路上看到垃圾就捡，让夫人十分不解。路乞说：“我重视我的‘环境’。黄石是我的生活环境，我只是希望它更干净、更美好。”路乞也许不懂“身体力行”、“潜移默化”等中国成语，却用实际行动感动着他身边的人。在黄石，已有数百名志愿者跟他一起，不定期地做着捡拾垃圾、宣传环保的工作。路乞把它称作“五意工程”（义务、意识、意志、意气、毅力）。
当然，路乞认为环境问题不能仅靠捡垃圾解决，他更爱与市民交流，传播爱护环境的意识。“太多人觉得环保根本‘没关系’了！前几天在黄石，一个人一边说‘知道你的事情，见到你很高兴’，一边就随手扔掉香烟盒来和我握手———他根本不理解我的行动的意义。我马上把他的香烟盒捡了起来。另外，一些中国人的家里都是非常干净的，可是一出家门几步远，就很脏了。这就不是卫生习惯的问题，而是心态的问题。我要捡的不只是路面的垃圾，更是人心里的垃圾。”
希望同学们从一点一滴做起，爱护环境，爱护我们赖以生存的家园！

参考译文
亚洲的沙尘暴
几个世纪以来，沙尘暴一直是困扰许多亚洲国家的主要灾害。为解决这一问题，科学家们尝试了许多方法。中国为帮助解决这一问题发动了群众性的运动。
沙尘暴是裹着沙尘的强劲而又干燥的风，它们（沙尘暴）非常密集以至于人们都无法看到太阳；风有时会很大，足以能够移动沙丘。世界上发生沙尘暴的四个主要地区是中亚、北美、中非和澳大利亚。出生于内蒙古的任建波描述了他小时候在沙漠中经历过的一场可怕的沙尘暴。“被沙尘暴所困是可怕的经历，”他说到，“什么也干不了。那是我遭遇过的最可怕、最危险的境况。我原以为我会消失在沙尘中的。”
中国的西北部是中亚沙尘暴中心地带的一部分。沙尘暴在沙漠地区形成。因“荒漠化”越发严重，中国近年来发生沙尘暴的次数明显增加了。这是一个过程，当土地因为气候的改变以及人们对树木的砍伐和对草木的挖掘而变成沙漠时，这一过程就会发生。
沙尘暴有时会影响到北京。居民醒来时，看到昏黄的天空，狂风夹着黄沙在城里肆虐。暴风有时持续一整天，车辆开得很慢，因为浓浓的尘埃降低了能见度。
中国中央气象台在沙尘暴抵达北京时的几个星期前就能预报它，但有时候沙尘暴的威力是惊人的。气象专家们建议，在沙尘暴抵达京城时，人们不要外出，可大量的人仍然要去工作。街上许多人戴着面罩。现住北京的黄晓梅这样说：“在沙尘暴中骑车真是可怕，风很大，很难呼吸，沙尘使我生病了，可我还得去工作啊。”
沙漠离北京的西郊只有250公里，为防止它继续接近北京，北京政府在组织人们栽树。他们已经栽了三百亿棵树，而且计划在今后的五年中继续植树。
绿色运动
有些国家在保护环境方面比其他国家做的好。在欧洲，德国和一些北欧国家都在努力致力于环境的改善。德国等国家的人民把垃圾放到不同的袋子中，如：把纸放在一个袋中，把塑料放在另一个袋中。然后，把垃圾运走，而且，有可能的话，还要回收再用。在电冰箱和器雾剂的铁罐中常见的化学物质氟氯化碳是禁止使用的。还有法律规定人们不得过量使用燃煤。
二十世纪七十年代，人们对于环境有了更多的认识，于是绿色运动兴起并迅速蔓延整个欧洲。绿色运动力图使各国政府严肃认真的考虑环境问题和如何关爱环境。他们收集了有关工业如何破坏环境的信息并将其公诸报端。

教师点拨：

动词不定式具有动词特点，可以有自己的宾语和状语，组成动词不定式短语。动词不定式的肯定形式是to＋do；其否定形式是notto＋do。完成式：to+havedone；进行式：to+bedoing。具体用法：

　1、作主语

　Toseeistobelieve.

　但在英语中，常用it作形式主语，真正的主语即动词不定式放在后面。如：

Itswrongtoplaytricksonotherpeople.

2、作宾语

不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问句+带to的不定式”。

1）及物动词+带to的不定式结构：

只能跟动词不定式的动词，常见的有：want,wishafford,agree,aim,appear,ask,decide,demand,desire,determine,expect,,happen,hope,intend,manage,offer,pretend,promise,prepare,refuse,seek,t,undertake等。

Hemanagedtosolvethecomplicatedproblem

Thestrangerofferedtoshowmetheway.

Mr.SmithundertooktobuildanewplantinSouthAfrica.

2）动词+疑问代（副）词+不定式：

常见的动词有：advise,decide,discuss,findout,,know,learn,regard,remember,see,teach,tell,understand,等。常用的疑问代（副）词有what,when,where,which,how,whether等，但不包括why。

Hedoesnotknowwhentostart.

Iwillshowyouhowtodealwithit.

有时，不定式可由it代替，而把不定式放到后面去。这可以用这一结构表达：动词（如find,think,consider,feel等）+it+形容词+不定式，it是形式宾语，真正的宾语是后面的动词不定式。

Sheconsidersitnecessarytomakefriendswiththem.

Wefinditdifficulttofinishallthehomeworkbefore9oclock.

3）love，like，begin，start，hate，prefer等词后面可以接不定式，上述动词后面除接不定式外，还可以接动名词，意思无很大区别。

Ilikeswimming，butIdontliketoswimnow.我喜欢游泳，但我现在不想游。

　4）stop，forget，remember，goon，try等词或短语后面可以接不定式。上述动词后面接不定式和接动名词意思大不相同。

例句：Whentheteachercamein，thestudentsstoppedtalking；whenhecameout，thestudentsstoppedtotalk.

当老师走进来时，学生们停止说话；当老师走出去时，学生们又开始说话。

3、作表语

一般情况为主语是不定式（表示条件），表词也是不定式（表示结果）：

Toworkmeanstoearnaliving.

另一种情况为主语是aim,duty,hope,idea,job,plan,problem,purpose,thing,

Hisaimistostudyabroadinthenearfuture.

　4、作宾语补足语

1）tell，ask，want，order，teach，invite，warn，wish，help，get，wish，help等词后面常接不定式作宾补。如：

Itellhimnottogotherebybus.

Edisonsmothertaughthimtoreadandwrite.

2）let，make，have，see，hear，feel，watch，notice后面接不带to的不定式作宾补。如：

Thebossmakesthemwork16hoursaday.

Shewasheardtosinginthenextroom.(若变成被动语态，要加上to)

3）不定式作定语

Hegavemeaninterestingbooktoread.

如果动词不定式和前面所修饰的词构成动宾关系，若动词是不及物动词，后面就得加相应的介词.

Haveyougotsomepenstowritewith？

5、不定式作状语

作原因状语：

Theyarequitesurprisedtoseethegreatchangestakingplaceinthearea.

作目的状语：

Sheraisedhervoicetobeheardbetter.

作结果状语：

Hegottothestationonlytobetoldthetrainhadgone.
