重要的有意义的显著的相当大的
陷阱
⚠️significant vs. considerable:「有意义」vs. 「量上可观」
The company has invested considerable resources in developing its new product line.
considerable = significant(都是「很大的/重要的」,可以互换)
considerable(相当大的,量上可观——投入了很多资源,不含「这很重要有意义」);significant(有重大意义——如果说 significant resources,暗含「这份投入有深远意义」,不只是量大);描述资源投入量时用 considerable 更精准
该公司在开发新产品线上投入了相当大的资源。(considerable = 量上可观,非 significant 的「有意义/显著重要」)
⚠️significant vs. important:书面 vs. 口语,程度不同
The new findings represent a significant breakthrough in our understanding of how memory works.
significant = important(完全可以互换,只是风格差异)
significant(有实质意义,结果有影响,学术/正式书面语);important(重要,口语/书面均可,但比 significant 语气稍弱,不强调「有实际影响和意义」);学术语境首选 significant
这些新发现代表了我们对记忆运作方式理解的一项重大突破。(significant = 有实质意义的重大,比 important 更书面学术)
