每日GRE单词洗脑大法：“Oblivious” ，未察觉的风险可能很严重

Oblivious

adj.

未察觉的

Oblivious和Obvious看起来是不是有点像？Oblivious的感觉和Obvious adj.明显的 这个词是相反的，是没有注意察觉的意思。这个词的中文“未察觉的”可能会给很多同学一个错误的认知，觉得是imperceptible的意思，其实在语境里，oblivious有种贬义一种傻儿吧唧啥都不知道的无知感。想象一个老同学，在聚会的时候一直呱呱地和别人讲自己孩子多么多么厉害，完全他一直就霸占着话头没给别人一点炫耀的机会和时间：he got too absorbed，oblivious to the passage of time。
