1. A method of editing a language communication sheet comprising: providing a picture/text editing interface, wherein the picture/text editing interface has a picture/text editing area and a function key area; providing a dividing function for a communication sheet to divide the picture/text editing area into a plurality of language communication units; providing an expression database, the expression database comprising a plurality of expressions, wherein the expressions comprising expressions in the first language and expressions in the second language, and two expressions individually from the first language and the second language having substantially identical meanings are correlated, the expression database comprises a plurality of correlation indices, each correlation index correlating an expression having a substantially identical meaning in the first language and the second language with identical meaning have a same correlation index so that the two vocalizations individually in the first language and the second language with substantially identical meanings are correlated; providing a picture database, the picture database comprising a plurality of pictures, wherein at least one of the pictures is correlated with one expression of the expression database, each picture comprises a picture file name, and each picture file name corresponds to one correlation index so that a correlation is provided between the picture and an expression; and providing a vocalization database, the vocalization database comprising a plurality of vocalizations corresponding to the plurality of expressions, wherein the vocalizations comprise vocalizations in the first language and vocalizations in the second language, and two vocalizations individually from the first language and the second language having identical meanings are correlated, wherein at least one of the vocalizations is correlated with one expression of the expression database, each vocalization comprises a vocalization file name, and the vocalization file name corresponds to one correlation index so that a correlation is provided between the vocalization and an expression; providing a correlation searching function, wherein the correlation searching function performs at least one of the following functions: finding a corresponding picture for an expression according to the correlations between the expressions and the pictures; and finding a corresponding vocalization for an expression according to the correlations between the expressions and the vocalization; providing an expression insertion function inserting an expression into any one of the language communication units; providing a picture insertion function inserting a picture into any one of the language communication units; and providing a language assigning function, wherein the language assigning function assigns expressions in all language communication units as expressions in the first language or as expressions in the second language in one operation.
