【正确答案】正确答案：Interlingua errors mainly result from cross-linguistic interference at different levels such as phonological, lexical, grammatical or discoursal etc. The intralingual errors mainly result from faulty or partial learning of the target language, independent of the native language. There are learning strategies-based errors, communication strategies-based errors, induced errors and some compound and ambiguous errors among which overgeneralization or cross-association have been well exploited.
