|by contrast/in contrast;相比之下,比较起来
"by comparison" 是一个英语短语,常用于引出两个事物或情况的对比关系,强调通过比较凸显差异。其核心含义是"相比之下"或"通过比较",通常与"with"或"to"连用构成完整搭配,例如"by comparison with..."(与...相比)。牛津词典将其定义为"used especially at the beginning of a sentence when you are comparing two things"(特别用于句首以比较两件事物)。
在句法结构中,该短语既可作插入语使用,也可引导状语从句。例如:"The tropical rainforest receives 2000 mm of rain annually. By comparison, the desert ecosystem gets less than 250 mm."(热带雨林年降雨量达2000毫米,相比之下,沙漠生态系统的降雨量不足250毫米)这种用法在学术写作中尤为常见,剑桥词典指出其特别适用于强调差异性对比的场景。
该短语的语义强度介于中性比较词"compared to"与强调反差词"in contrast"之间,既能客观陈述差异,又带有轻微的强调效果。例如在经济学报告中:"Last quarter's GDP growth reached 5.2%. By comparison, the same period last year showed only 3.1% growth."(上季度GDP增长达5.2%,相比之下,去年同期增长率仅为3.1%)这种用法既呈现数据差异,又暗示发展态势的变化。
权威语言学研究显示,"by comparison"在正式语体中的使用频率是口语的3.2倍,常见于科研论文、商业报告等需要精确对比的场合。其近义词包括"in comparison"和"when compared",但语用学研究表明"by comparison"更侧重主动比较的行为过程。
“by comparison” 是一个英语短语,主要用于引出两个事物之间的对比,强调通过比较凸显差异或相似性。以下是详细解释:
独立使用:直接放在句首或句中,表示与前文提到的内容形成对比。
例句:
"The first experiment failed. By comparison, the second attempt was successful."
(第一次实验失败了,相比之下,第二次尝试成功了。)
接比较对象:后接“with” 或“to” 引出具体比较对象。
例句:
"By comparisonwith the bustling city, the village feels peaceful."
(与繁华的城市相比,这个村庄显得宁静。)
“in comparison”:意义和用法几乎相同,可互换。
例句:
"In comparison to last year, profits have doubled."
“compared to/with”:功能类似,但需注意:
通过以上分析,可以更准确地运用这一短语增强表达的对比性。如需进一步区分细微差别,建议结合具体语境练习使用。
