The Contrast Analysis of Conjunctive Auxiliaries Used in Inverse Conditions Zhang, Rui Conjunctive auxiliary can be irreplaceable when it is specifically used for expressing the sense relations and logical relations in Japanese.In the using of conjunctive auxiliaries which express inverse conditions, “temo” and “tatokorode”can be seen as the most representative one. Because of the polysemy of those two words, this thesis aims at analyzing their meanings for express inverse conditions, which is based on the using of meanings of those two words. Moreover, this thesis picks up illustrative sentences in corpus and analyzes similarities and differences between “temo” and “tatokorode” on the basis of subordinate clause’s property and tone characteristics of main sentence.Finally, we draw a conclusion as follows: (1) When there comes out assumed inverse condition,“temo” can be used in both sentences with the meaning of impossible event or the meaning of possible event. However, compared with “temo”, “tatokorode” can be only used in the sentence with the meaning of possible event. Moreover, “temo” can be also used in the sentences with the meaning of disposable condition and constancy. While “tatokorode” can be only used in the sentence with the meaning of disposable condition. (2) Although “tatokorode” can lead specified inverse condition, it is different from “temo”. When “temo” is used in specified inverse condition, it can lead the sentence with the future meaning without the limit on tense. However, “tatokorode” can only lead specified inverse condition which has been already achieved and the tense of its main sentence is usually past tense. (3) The mood between “temo” and the main sentence can be correspondingly used with mood of attitude expression”, “mood of presentation and “mood of value judgment” in terms of its responsive meaning. In contrast, the main sentence of “tatokorode” usually has “mood of attitude expression” which is can not correspondingly used with “mood of value judgment”, “mood of function”, “mood of presentation” and “sentence of phenomenon description”. This study makes a contrast analysis of“ temo” and “ tatokorode” on the basis of previous studies and has not had a deep discussion about other conjuctive auxiliaries used in inverse conditions. Therefore, it should become the subject which we are going to talk about later.
