Abstract: This specification discloses a method and system for learning a language. This invention takes the language data selected by a learner or a default test base as the learning content and improves the learner's language ability through tests about the learning content. The learner is allowed to arbitrarily update the language data stored in a learning database. The system according to the present invention contains a grammar analysis engine. This engine analyzes the grammar of the language data in the learning database according to the grammatical rules collected and stored in a language grammar database, converts the language data in the learning database into test problems according to the problem models stored in a problem model database, and finally performs language tests using the grammar analysis processor and provides the test results (such as error analysis and explanation).
