語言階級 The Level of Language[1]

語言[2]，在抽象化程度上，有高階、低階之分。但語言階級，不足以反映出該語言的難度、深度或廣度。	Languages[2] are distinguished, by their levels of abstraction, into higher-level ones and lower-level ones. However, the level of a language is not necessarily showing its difficulty, depth or scope.
一人學習高階語言所需的智商及精力，並不亞於學習低階語言所需者；其中，該等語言階級是相對於該人的母語階級而言。	A person cannot count on less intelligence and effort to learn a higher-level language than to learn a lower-level language; wherein the levels of the two languages are comparing with the level of the person's mother language.
