专科是不是专业的意思？ 如果是， 这个词用英文是"major". (e.g. "What's your major?") 本科也许是undergraduate. (Can you use 本科in a sentence? Maybe it could help me translate it.) 不认为英文没有"classifiers" (e.g. 个， 匹， 本， etc.) 只是有“一“， 一可以成中文翻译: “a"， 有时候用"an". e.g. "A horse", "An axe", "An American", "An elephant", "An idiot", "An ox", "An underground lair", etc. 明白了呢？

In American English those would be "undergraduate" and "vocational school."
