There are three kinds of usage in tag questions: “confirmation-seeking usage," “echo usage" and “ironical usage." “Confirmation-seeking usage" is the tag question of a contrasting polarity, but “echo usage" and “ironical usage" are the tag question of a matching polarity. The contrasting polarity is the case where if the host clause(original sentence) is negative, the tag becomes positive and vice versa. The matching polarity is the case where although the host clause is negative, the tag is also negative, and although the host clause is positive, the tag is also positive. I enumerated the items that we must keep in mind and the several special items in this thesis. I noted the exceptions which are different from the normal cases.

Parking gear is essential parts of automotive to park on flat or slope ground. Parking of, especially, big-sized vehicle such as bus and truck is very important problem related to safety. Stability of parking gear may differ from contact location between parking gear and pawl. The purpose of this study is to investigate the influence of stability depending on contact location using numerical analysis. Furthermore the results obtained by numerical analysis were applied to real vehicles to evaluate established-product of parking gear. As the results, safety criterion of parking gear showed below 0.31ton and thus it was confirmed that parking gear of this study was suitable to small-sized vehicle.

Hot forging is widely used to manufacture many industrial parts such as machine, automotive and so on. It is important to simulate the relations or characteristics between preform and die before designing the die. The purpose of this study is to investigate the forging characteristics of parking gear with nonlinear gear groove, thus the behaviors of preform can be predicted in advance and finally they can be applied to die design. As the results, since the distributions of high effective strain rate of parking gear were less than 3%, it was predicted that the manufacturing of parking gear with nonlinear gear groove might be possible. Furthermore it was observed that, in this study, the effective stress of bottom die was lower than that of top die.

There are various kinds of the usage of 'it' in English. It is as follows: 1. The usage of pro-form Red is not a color at all for animals ; for them it is dark grey or black. 2. Expletive 'it' 2.1. Climate It's raining 2.2. Time It's ten o'clock 2.3 Distance How far is it for your mansion from here? 2.4 Environment How is it in the market? 3. Anticipatory 'it' To know what colors bees can see is interesting. → It's interesting to know what colors bees can see. To know what colors bees can see was replaced with it. In other words, placing to know what colors bees can see in thematic position is to emphasize this. It is called 'it' anticipatory. 4. Anaphoric and Cataphoric 'it' 4.1 Anaphoric 'it' They get no advice and therefore they keep repeating the same mistakes. It's a terrible shame. 4.2 Cataphoric 'it' It never should have happened. She went out and left the baby unattended. 5. 'It' Replacing Nominal Complement believe it. John said that Bill finked on Max, but I didn't. It replaces with Bill finked on Max, nominal complement. 6. Factive 'it' The fact can place in front of that - clause in factive predicates sentences.('the fact' is one that a speaker presupposes in factive sentences.) This can be contracted with 'it' (1) I regret (it) that he can't help doing things like that. (2)*I believe it that he can't help doing things like that. 7. Extraposition 'it' and 'It'- Deletion 7.1 Extraposition 'it' It is the rule that moves embedded sentence into the end of sentence and the place is replaced by 'it'. That the earth is round is obvious. → It is obvious that the earth is round. 7.2 'It' - Deletion It is the rule that ddetes 'it' immediately before embedded sentence obligatorily. 1) *It that the earth is round is obvious. Like the following sentence, if extraposition is taken the above sentence, it is needless 'it' - deletion. 2) It is obvious that the earth, is round. 8. Cleft Sentence 'it' It is the rule that must place pronoun 'it' in the first position of the sentence and then 'be' verb. Mr. Kim gave Miss Lee a book. → It was Mr. Kim who/that gave Miss Lee a book. 9. Idiom 9.1 It is no use (good) - ing 9.2 It goes without saying etc. In this way, 'it' is divided into 9 sub-chapters in this thesis.
