The study investigated the representations of L1 Thai learners on English number agreement, a form which is non-existent in Thai. It is hypothesized that the L2 learners have target-like syntactic representations of English number agreement... 80% on the structures of singular/plural head with modification. However, deviant production was found on irregular nouns. The results indicated the learners’ target-like syntactic representations of English number agreement but incomplete knowledge

that the frequency of verbs occurring in the target complement constructions probably contributed to the learners’ low-level constructional schemas (i.e. the abstract representations of constructions which are lexically specific) and their language use.

This research aims to discuss whether Thai-Chinese unbalanced bilinguals who possess low proficiency in Chinese stored syntactic representation of both Thai and Chinese together or separate. The experiment tested Active-Passive structures through

with embedded theoretical grammar, i.e., orthographical, phonological and semantic representation.
