The conceptual shift and collocation between concreteness and abstractness enable her poems to carry both linguistic power and emotional strength; the conceptual images created by her abstract thinking and unique perception make her poems achieve originality and readability; her conceptual self built by the use of first person pronouns is actually not that of a person but that of a personified mule who was indignant about its heavy workload yet unable to speak against its predestined destiny. Although suffering from brain paralysis, the poet is shown by this review to be a sensible manipulator of words, which reveal the unique beauty in her language and show the suppressed sadness in her heart.展开更多

An acceptability judgment task and a written interview task were used to collect data of L2 learners＇ interpretation of English articles. The results reveal that the L2 learners differ from native speakers in their computation of uniqueness of target NPs and in their L2-English article choices, and this difference can be attributed to their conceptual knowledge formed in the acquisition of the mother tongue and to their processing of such knowledge. Pedagogically, this study provides an explanation of L2-English article substitution errors from the perspective of conceptual transfer.展开更多
