d. generating an exercise based on the selected text, the analytical data, and the user data.
9. A method according to claim 8, wherein linguistically analyzing the selected text includes analyzing both morphology and syntax of the text.

e. scoring the results of use of the exercise and updating the learner's profile database based on the performance of the user in doing the exercise.
11. A method according to claim 8, wherein the learner's profile database includes profile data for a non-null set of learners, such profile data including parameters characterizing, for each learner in the set, such learner's linguistic competence.
12. A method according to claim 11, wherein the profile data includes parameters separately characterizing at least one item selected from the group including lexical competence, grammatical competence, semantic competence, and phonological competence.
13. A method according to claim 12, wherein the profile data includes parameters separately characterizing at least two items selected from the group including lexical competence, grammatical competence, semantic competence, and phonological competence.
14. A method according to claim 12, wherein the profile data includes parameters separately characterizing at least three items selected from the group including lexical competence, grammatical competence, semantic competence, and phonological competence.
15. A digital storage medium digitally encoded with instructions, which when loaded into a computer establish a system for personalized language exercise generation, the system comprising:
a. a text input for receiving a selected text;
b. a linguistic analyzer coupled to the text input for analyzing the selected text;
c. an exercise generator coupled to the linguistic analyzer for generating a language exercise from the selected text; and
d. a learner's profile database, coupled to the exercise generator, in such a manner that the language exercise reflects parameters of a user with respect to whom there exists an entry in the learner's profile database.
16. A medium according to claim 15, wherein the linguistic analyzer includes a morphology analyzer and a syntax analyzer.
17. A medium according to claim 15, wherein the system further comprises:
e. a scoring arrangement for scoring the results of use of the exercise and for updating the learner's profile database based on the
performance of the user in doing the exercise.
18. A medium according to claim 15, wherein the learner's profile database includes profile data for a non-null set of learners, such profile data including parameters characterizing, for each learner in the set, such learner's linguistic competence.
19. A medium according to claim 18, wherein the profile data includes parameters separately characterizing at least one item selected from the group including lexical competence, grammatical competence, semantic competence, and phonological competence.
20. A medium according to claim 18, wherein the profile data includes parameters separately characterizing at least two items selected from the group including lexical competence, grammatical competence, semantic competence, and phonological competence.
21. A medium according to claim 18, wherein the profile data includes parameters separately characterizing at least three items selected from the group including lexical competence, grammatical competence, semantic competence, and phonological competence.
