分析主干:Wal-Mart is set to announce a initiative: it will buy cotton...
1.本句冒号后的内容是对前文initiative 的详细阐述,相当于一个同位语从句。
2.冒号前的分句中,谓语动词用了be set to do 结构,过去分词短语aimed to...是initiatives 的后置定语,相当于一个定语从句。
3.冒号后的分句中,结构简单,其中helping to...是现在分词短语,作谓语动词buy 的状语,表示目的。
译文:本周沃尔玛超市准备出台一项重大举措,目的在于帮助棉农种植有机棉:沃尔玛将以更高的价格收购过渡型的棉花,以此帮助扩大一种重要有机原材料的供应。
