It's not a language for science, research, a language we're used to in universities, a language we use in the workplace, a language we rely on if we were to perform an advanced research project, and it definitely isn't a language we use at the airport.
不是科学用的语言， 不是研究用语， 不是大学里用的语言， 不是工作场合的语言， 不是我们进行尖端研究时的用语， 而且绝对不是机场用语。
