摘要：Research shows that there is no general consensus on why some students are not
successful in learning a foreign language. Sparks and Ganschow (1993) claim that
learners may have deficits in either the phonological, semantic or syntactic systems in
their native language, and that this can affect how well they can master a foreign
language. In a similar vein, Downey, Snyder and Hill (2000) found a correlation between
phonological processing difficulties and learning problems that foreign language learners
face. However, Castro and Peck (2005) state that even students who do not appear to
have any language-learning deficits, such as those who score highly on the Modern
Language Aptitude Test, encounter difficulties in the foreign language classroom. This
finding seems to indicate that factors other than language-learning deficits may affect
one¡¯s ability to learn a foreign language.
