From table 4.4, it can be concluded that there are 27 times appearing in the conference and 13 times for the combination of Oral presentation and Text. The speakers were likely to say something unrelated to the topic during the transition phase like the greeting words, which is mainly led by the text. The speakerswere also willing to emphasize the content by putting words on the screen while telling the audience exactlythe same words. Therefore, it is normal to see that the frequency of the combination of Oral presentation and Text is the highest in the overlapping relationship. c) Analysis of the Interpersonal Metafunction According to Halliday’s systematic functional grammar, modality plays an important role in explaining the relationship among speakers. No matter it is verbal or nonverbal, it has an influence on the interpersonal relationship. Due to the limited time and experience, the study mainly selected the modality “can” as the subject to dig out the interpersonal meaning in the Apple Event 2018. As for the interpersonal metafunction in complementary relationship, the modal operator can appears 57 times in the complementary relationship, including highlighting relationship 10 times, primary and secondary relationship 25 times and coordination relationship 22 times. It can be noticed that the modal operator most exists in primary and secondary relationship, which functions as the main approach of explanation during the product launch conference. It means that the speakers are clinging to use reinforcement relationship to conduct a positive meaning for the audience. As for the interpersonal metafunction in non- complementary relationship, the modal operator can’t appears four times in the non-complementary relationship, which all belong to the type of overlapping relationship. The non-complementary relationship means that the only one mode has already expressed thewhole meaning and there is no need for other modes to supplement. The use of modal operator can help to express positive information to the audience, while some low modal operator with high politeness in overlapping relationship conduct less meaning during the conference. V. C onclusion It is clear that the Apple Event has applied rich semiotic resources which can be represented by multimodal features mainly including visual and auditory modes. Through the detailed analysis, the oral presentation by speakers is the main media during the conference, which means that the auditory mode severs as the primary mode to construct the meaning to the audience. And the visual modes are complementary to the auditory modes. It is a complementary relation between the visual and auditory modes in the most occasions, especially the non-reinforcement relation. Based on the interpersonal function, it is apparent that the low modal operator can has the high inclination to the complementary relationship, which plays an important role in constructing the positive attitude and evaluation of the speakers. With little Question and no Command, the application of modal operator indicates that the discourse is of high politeness. In a word, every mode has its place in expressing and conveying meaning, whose various collocation and interaction makes the whole Event successfully held. And the use of the low modal operator establishes a closer relationship between the speaker and the audience and try to persuade and encourage the audienceto cultivate the sense of purchase. One of the limitations of this study is that the paper only employed the iPhone Launch part as its corpus. And it is not enough to find out the exact distribution rules of the synergies between the auditory and visual modes, which may be not persuasive and evident to some extent, also the entire study of SFL has not been conducted duo to limited knowledge and experience. Further research must conduct larger- scale studies to ensure the objectivity of the study. In addition, in this study, only the auditory and visual modes are analyzed, much more comprehensive studies can be carried out to analyze the other modes whosecollocation as well as interaction should be further analyzed through technical means rather than artificial ways. Third, there are few criteria for researchers to divide the dynamic discourses, so framework of the transcribing of the dynamic multimodal discourse should be further studied.
