造心     

毕淑敏

蜜蜂会造蜂巢。蚂蚁会造蚁穴。人会造房屋,机器,造美丽的艺术品和动听的歌。但是,对于我们最重要最宝贵的东西──自己的心,谁是它的建造者?   

我们的心,是长久地不知不觉地以自己的双手,塑造而成。

造心先得有材料。有的心是用钢铁造的,沉黑无比。有的心是用冰雪造的,高洁酷寒。有的心是用玻璃造的,晶莹脆薄。有的心是用木头造的,安稳麻木。有的心是用垃圾造的,面目可憎。有的心是用谎言造的,百孔千疮。

造心要有手艺。一只灵巧的心,缝制得如同金丝荷包。一罐古朴的心,淳厚得好似百年老酒。一枚机敏的心,感应快捷电光石火。一颗潦草的心,门可罗雀疏可走马。一滩胡乱堆就的心,乏善可陈杂乱无章。一片编织荆棘的心,暗设机关处处陷阱。一道半是细腻半是马虎的心,好似白蚁蛀咬的断堤。一朵绣花枕头内里虚空的心,是假冒伪劣心界的水货。

心的边疆,可以造得很大很大。像延展性最好的金箔,铺设整个宇宙,把日月包涵。没有一片乌云,可以覆盖心灵辽阔的疆域。没有哪次地震火山,可以彻底颠覆心灵的宏伟建筑。没有任何风暴,可以冻结心灵深处喷涌的温泉。没有某种天灾人祸,可以在秋天,让心的田野颗粒无收。

心的规模,也可能缩得很小很小,只能容纳一个家,一个人,一粒芝麻,一滴病毒。一丝雨,就把它淹没了。一缕风,就把它粉碎了。一句流言,就让它痛不欲生。一个阴谋,就置它万劫不复。

心可以很硬,超过人世间已知的任何一款金属。心可以很软,如泣如诉如绢如帛。心可以很韧,千百次的折损委屈,依旧平整如初。心可以很脆,一个不小心,顿时香消玉碎。

优等的心,不必华丽,但必须坚固。因为人生有太多的压榨和当头一击,会与独行的心灵,在暗夜狭路相逢。如果没有精心的特别设计,简陋的心,很易横遭伤害一蹶不振,也许从此破罐破摔,再无生机。没有自我康复本领的心灵,是不设防的大门。一汪小伤,便漏尽全身膏血。一星火药,烧毁绵延的城堡。

心为血之海,那里汇聚着每个人的品格智慧精力情操,心的质量就是人的质量。有一颗仁慈之心,会爱世界爱人爱生活,爱自身也爱大家。有一颗自强之心,会勤学苦练百折不挠,宠辱不惊大智若愚。有一颗尊严之心,会珍惜自然善待万物。有一颗流量充沛羽翼丰满的心,会乘上幻想的航天飞机,抚摸月亮的肩膀。

当以我手塑我心的时候,一定要找好样板,郑重设计,万不可草率行事。造心当然免不了失败,也很可能会推倒重来。不必气馁,但也不可过于大意。因为心灵的本质,是一种缓慢而精细的物体,太多的揉搓,会破坏它的灵性与感动。

造好的心,如同造好的船。当它下水远航时,蓝天在头上飘荡,海鸥在前面飞翔,那是一个神圣的时刻。会有台风,会有巨涛。但一颗美好的心,即使巨轮沉没,它的颗粒也会在海浪中,无畏而快乐地燃烧。

单项选择题

Passage Two

Britain’s emissions of greenhouse gases, blamed by many scientists for contributing to global warming, have fallen by 14 percent since 1990, according to the latest government report.
British lakes and rivers are also on the road to recovery from acid rain poisoning, following successful curbs to air pollution from cars and heavy industry.
The report by the National Atmospheric Emissions Inventory (NAEI) attributed the drop in greenhouse gas emissions to several factors including: the introduction of catalytic converters on cars, a move toward low sulphur and lead-free petrol and a switch to gas from coal and oil in power generation.
Environment Minister Michael Meacher said the downward trend was welcome, but warned of complacency.
"Even though these figures are encouraging, we must not be complacent. There are still significant problems where we need to do more, for example, to further reduce greenhouse gases and harmful pollutants (污染物) such as ammonia and particulate matter," he said in a statement.
The government has a target to cut greenhouse gases by 23 percent by 2010 on 1990 levels. This is almost double the target of 12.5 percent to which the UK is committed under the Kyoto Protocol and there are signs that emissions are rising as generators return to using coal-fired power stations in the face of rising natural gas prices.
The Department of Environment Food and Rural Affairs (DEFRA) said substantial curbs on sulphur dioxide emissions across the UK and Europe had cut acid rain by half over the last 12 years. "Damaged freshwater lakes and streams are showing signs of recovery," it said.
But DEFRA warned of a new threat. "Nitrogen oxides and ammonia are the main air pollutants that must be tackled to stop future damage. "
The bulk of Britain’s ammonia emissions come from farm animal manure (粪肥), causing over-enrichment of land and waterways, said the report. Certain species rampage unchecked through this ultra-fertile environment, smothering the slower growing plants beneath them and choking streams and rivers. Nitrogen oxides enter the atmosphere from car exhausts and industry, creating health-damaging ozone and contributing to acid rain.

What is UK’s committed target under the Kyoto Protocol to cut greenhouse gases by 2010

A.To cut by 23% on 1990 levels.

B.To cut by 25% on 1990 levels.

C.To cut by 12.5% on 1990 levels.
