3. He is a nerd
nerd 是指一些年轻人,每天只懂读书、考试,但对生活上的其他事情,都很生疏。 (A person always buries his nose in books, but not good at social situations.)由於美国十分重视多方面发展的教育 (well-rounded),所以许多老外认为 nerd 虽然学识不错,但很乏味;有IQ,但缺乏EQ,只是社会上无足轻重的「书虫」或「蠢货」而已。(IQ = Intelligence Quotient ; EQ = Emotional Quotient) nerd 可用复数,动词也能用其他时态。
因此可以说:He used to be a nerd in high school
