invasive /ɪnˈveɪsɪv/CET6丨IELTS丨TOEFL 外刊例句 Doctors have learned a lot. They have stopped rushing covid-19 patients onto ventilators, which can cause lung damage. Oxygen supplied through small prongs in the nostrils is much less invasiveand often does the job.医生们学到了许多。他们不再急着给新冠患者使用呼吸机，因为呼吸时机导致肺损伤。通过鼻套管提供氧气，侵入性小得多，而且通常有效果。

——《经济学人》 基本释义 invasive：You use invasive to describe something undesirable that spreads very quickly and that is very difficult to stop from spreading.adj. 侵入的；扩散的 追根溯源 单词invasive里的词根vas来自拉丁语vasi，表现“走”，所以，在英语里包罗vas/vad/wad的单词，多与此相关。例如：invade /ɪnˈveɪd/ v. 侵略，涌入evade /ɪˈveɪd/ v. 逃避，逃脱pervade /pəˈveɪd/ v. 广泛，弥漫pervasive /pəˈveɪsɪv/ adj. 普遍的，盛行的wade /weɪd/ v. 艰苦行走前缀in表现在内里，后缀ive表现形容词，所以，in+vas+ive=向内里走的→入侵的，切入的，扩散的。
