Pronouns of Shenme Type are encoded with the senses of interrogation,existence and universal quantification,the last being divided into left-ward and right-ward ones.On the basis of linguistic theoretical analysis,the structural differences between the two senses of sub-universal quantification lies in the(non)-existence of focal element.On the basis of cross-linguistic comparison and second language theories,the present study yields the following empirical results:1)no acquisition difficulty was found with the interrogative sentences,whereas the acquisition of existential sentences is subject to the negation category;2)the acquisition of the sentence with left-ward universal quantification may well be attributed to the typological features of L2-ers’ native language;3)the sentences with right-ward universal quantification involves more than one sense,and therefore its syntactic realization is hard to acquire for Russian learners;in contrast,Japanese learners can resort to the operational mechanism in their mother tongue to approach the native judgment.The present study thus puts forward Inter-language Integration Deficit Hypothesis,which proposes that adult L2 learners are mostly lacking the ability to coordinate and to integrate various distributional cues of heterogeneity.
