Farmers armed with powerful fertilizers and high-tech equipment are growing enormous quantities of corn and wheat, most of which is processed and refined to be tastier and more convenient ______is less nutritious.
选项
A、but
B、or
C、while
D、whereas
答案
A
解析
根据句意可知,玉米小麦经加工精制后变得更加可口、方便,但是营养成分就少了些。本句含有句意转折,所以排除B项。转折词后显然省略了it。while与whereas都可作为连词表示“尽管;然而”,用于比较或对比两个事实,即只在两者对比的情况下使用,而本句中转折前后的主语不变,所以排除C、D项。but作为连词,是可以表示针对同一主语的句意转折的,故选A。
