& 齐思卡说，&只要你在一个特定环境中改变了一种方法，到头来，你终究会帮助草类占了庄稼的上风。

According to Ziska, the steady increase in atmospheric CO2 since the beginning of the Industrial Revolution may have already had a major impact on the growth of at least one supremely costly weed.

齐思卡认为，空气中CO2浓度的持续增高至少对一种极其难对付的草种的生长产生了重要影响，这就是旱雀草，一种原生于中亚的草种，据信，这种草是19世纪中期用来压舱的土壤中或是农用种子中夹带的。

Ziska and his colleagues discovered, though, that the weed's flammability seems to have been greatly augmented by the increases in atmospheric CO2 that occurred during the period of cheatgrass's spread through the West.

当干燥的季节来临时，正值植株死亡，就会在地表上留下一层干燥、极易燃的叶子。

Working with Mark Mescher, Runyon and De Moraes studied how the weed finds its prey.

The wild aromatic root of the Queen Anne's lace weed has been fine-tuned over generations by selective herb gatherers until it has evolved into a sweet carrot of the garden; the udders of wild bovines have been selectively enlarged in a "unnatural" way to satisfy humans rather than calves.

野生胡萝卜那散发着香气的根，由挑剔的采药人经过了一代又一代的精心调培，才最终进化成花园里甜美的胡萝卜；野生牛的乳房也是通过&非自然&的方式进行了增大，以满足人类而不是小牛的需求。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
