1. 听写包答案:
One American investigation into the potential for storing CO2 on agricultural lands is taking place in California.
Soil scientist Whendee Silver of the University of California, Berkeley,
is conducting a first-of-its-kind study on large cattle farm in the state.
She and her students are testing the effects on carbon storage of the compost that is created from waste
both agricultural, including manure and cornstalks, and waste produced in gardens, such as leaves, branches, and lawn trimmings.
In Australia, soil ecologist Christine Jones is testing another promising soil-enrichment strategy.
Jones and 12 farmers are working to build up soil carbon by cultivating grasses that stay green all year round.
Like composting, the approach has already been proved experimentally;
Jones now hopes to show that it can be applied on working farms and that the result in carbon capture can be accurately measured.
It's hoped in the future that projects such as these
will demonstrate the role that farmers and other land managers can play in reducing the harmful effects of greenhouse gases.
For example, in countries like the United States, where most farming operations use large applications of fertiliser,
changing such long-standing habits will require a change of system.
Rattan Lal argues that farmers should receive payment not just for the corn or beef they produce
but also for the carbon they can store in their soil.

美国的一个关于在农业土地上储存二氧化碳的可能性的研究正在加利福尼亚州进行。
来自伯克利市加州大学的土壤学家Whendee Silver,
正在对该州的大型养牛场进行首次这类研究。
她和她的学生正在测试由废物制造的堆肥中储存的碳的作用,这些废物既来自农业废料,
包括粪肥和玉米杆,也来自花园中产生的废物,比如落叶、树枝和修剪草坪产生的废料。
在澳大利亚,土壤生态学家Christine Jones正在测试另一种可能的土壤增肥策略。
Jones和12位农民正在一起通过培育全年常绿的草来增加土壤中的碳质。
和堆肥一样,这种方法在试验阶段也已经被证明有效,
Jones现在希望证明这种方法能够应用在运营中的农场里,以及获取的碳的结果是能够精确计算的。
我们希望将来像这样的项目,
会证明农民和其他土地管理者在减少温室气体的有害影响中能够发挥的作用。
比如,在像美国这样的,大部分农业操作过程中都会使用大量肥料的国家,
改变这种存在已久的习惯将需要一种系统的变化。
Rattan Lal认为农民应该不仅从他们生产的玉米和牛肉中获利,
还应该为他们在土地中能够储存的碳质获得报酬。

2.阅读包答案:
然而,考虑到这样一个理论可能涵盖的范围和领域,它是否还算是简化就不那么明确了。
3.写作包答案:
Recently, it has been practiced by some local universities that dialect is made a compulsory course for some students, under which students are subject to learning the local dialect and then graded as one of the judging factors for them to graduate. On the one hand, people approving the practice maintain that it will help to prevent the dialect from extinguishing so that the local traditional culture and the cultural diversity can be enhanced, and the unique urban identity can be preserved simultaneously. On the other hand, people in opposition to the practice contend that it will give rise to the appearance of educational inequality, for the local students will enjoy absolute advantages over those from other places. Moreover, the inclusion of dialect in compulsory courses will bring forth other problems like teaching material, teachers and examination standards. As far as I am concerned, dialects, as an indispensable part of local traditional culture as well as a tool for communication, can be acquired and used voluntarily, not compulsorily.
