extensive与expansive的区别
extensive与expansive的区别
extensive有下面几种意思:
1.large in spatial extent or range or scope or quantity
同义词:extended
空间延伸范围大
2.broad in scope or content
同义词:across-the-board, all-embracing, all-encompassing, all-inclusive, blanket, broad, encompassing, panoptic, wide
范围和内容宽泛
3.of agriculture; increasing productivity by using large areas with minimal outlay and labor
农业上指使用大面积小成本
再来看expansive的几种意思:
1.able or tending to expand or characterized by expansion
能够或容易扩大的
2.of behavior that is impressive and ambitious in scale or scope
同义词:grand, heroic
伟大的,英雄一般的
3.marked by exaggerated feelings of euphoria and delusions of grandeur
自我感觉良好的,自我膨胀的
4.friendly and open and willing to talk
友好开朗的,健谈的
由此可以看出,两者虽然都有“大”的意思,但extensive是指大小和范围客观上“宽泛、广泛”;而expansive指的是“可以/容易变大、膨胀的”.前者多指客观上的大,后者则多指有变大的趋势.这一点也可以从两者的词根extend和expand的意思来加以区别.
