For now , my case rests mainly on the basic fact that the methane trend went the “ wrong way ” and that farmers began to irrigate wetlands at just the right time to explain this wrong - way trend 目前，我的探讨主要仰赖这样的基本事实：甲烷趋势发生错误，而农人开始灌溉湿地的时间与之相符，可为错误趋势提供解释。
Last month , talks among wto members brazil , india , the eu and the u . s . broke down over disagreements regarding subsidies granted to farmers in rich countries and trade barriers in developing countries 巴西印度欧盟和美国等世贸组织成员之间举行的谈判上个月因为在富裕国家对农人补贴以及发展中国家贸易壁垒的问题上出现分歧而破裂。
For instance those who grow herbicide - tolerant soybeans typically avoid the most noxious weed killer turning instead to glyphosate herbicides which are less toxic and degrade more quickly . insect - resistant crops also bring mixed benefits 例如，农人要是种植了耐除草剂的大豆，就会避免使用最毒的杀草剂，而改用毒性弱分解快的苷磷除草剂。
Some information is available however . according to the u . s . department of agriculture farmers who plant herbicidetolerant crops do not necessarily use fewer sprays but they do apply a more benign mix of chemicals 不过还是有些资讯可供参考，根据美国农业部统计，耐除草剂的作物不见得会降低农药的喷洒量，不过农人将使用比较温和的混合药剂。
The last section of the paper is sum up the main points of the poem . the poem about farm tools , melon and vegetables , cow , silkworm , tea in the successive dynasties 牛是农家一宝，耕地拉车吃苦耐劳，农人爱牛，制牛衣、筑牛室，牧牛生活其乐陶陶；诗人爱牛，歌咏不止，耕牛默默耕耘，不求功名，正可使诗人壮志难酬时借牛抒怀，托物言志。
Growing crops in naturally forested areas requires cutting trees , and farmers began to clear forests for this purpose in europe and china by 8 , 000 years ago , initially with axes made of stone and later from bronze and then iron 在自然森林地区种植作物必须砍树；欧洲与中国的农人约8000年前开始清除森林，最初用的是石斧，接著是铜器，再来是铁器。
With extensive floodplains lying within easy reach of several large rivers , it makes sense that broad swaths of land could have been flooded soon after the technique was discovered , thus explaining the quick shift in the methane trend 由于几条大河附近都有广阔的?滥平原，可想而知，一旦农人发明引水技术，大片土地很快就被水填满了，由此便可以解释甲烷趋势的快速改变。
Farmers like to limit the use of more hazardous pesticides when they can but gm crops also hold appeal because they simplify operations reducing the frequency and complexity of pesticide applications and in some cases increase yields 农人总是希望尽量少用比较危险的农药，不过基改作物之所以吸引人，是因为劳作手续简化了降低施用农药的频率及复杂程度，甚至可使产量增加。
In this movie , a farmer brings home an ordinary piglet . he already has many other animals , including ducks , roosters , birds , cats , sheep , cows , and dogs , all of which can communicate with each other . it is amazing that a dog can even take care of the piglet as though it were its own offspring 电影内容是描写一只看似平凡的猪被农人带回家，而那牧人家有许多动物，而且令人惊讶的是鸭子公鸡鸟猫羊乳牛狗等许多动物都能沟通，狗还把猪当成自己的孩子般地照顾。
