Several issues about this table are discussed below: 1. There are 2 sentences missed in this table. They are elliptical sentences (7 and 10). If we turn them into full sentences, they can be “it has unique structure of 3dimensional reticular arrays” and “ it is sugarless, full heattreated in high temperature, and vermin and germ proof”. In this way, sentences 7 and 10 play the role of Rheme with the Theme omitted. The original sentences just use nominal groups to describe the good features of the product, which is concise and very effective. In this sense, the feature of conciseness of the language of advertisements is satisfied. 2. For sentence 8, there are different ideas about it. Halliday thinks that “there” alone is Theme (1994: 44) while Thompson (1996/2020:138) argues that the existence is signalled not just by “there” but by “ there plus the existential process (typically realized by the verb „be‟)”. For the solution to the problem of “there be” structure, we can refer to Huang guowen (1999: 135 146). 3. Among the 13 analysed themes, there are two multiple Themes (sentence 5 and 10). The Themestructure of sentence 5 is made up of a textual theme “therefore” and an experiential theme “ the natural plete mountain palm mattress” and the Theme structure of sentence10 of a textual theme “and” and an experiential theme “tested 25,000 times in terms of durability” 4. The most important issue here is that there are 5 unmarked themes in this advertisement and the rest 8 are marked themes. The sentence like 9,12,13 and 15 (they are plex clauses in SMG) are structured like this: the first clause gives the information of the features of the product and the other clause describes the feeling brought by the features. For example, the sentence15 “ plete natural mountain palm fibres, you will be intoxicated in the fragrance of the mountain palm every night.” The first clause tells the feature that the product is made of mountain fibres and the other clause describes the feeling of “being intoxicated”. On many occasions, marked Themes ate used to draw attention to them and they occur when contextual reasons overrule the unmarked choice of subject as Theme (Thompson 1996: 121). With the description of the product‟s good features at the starting point in a sentence, readers can be more aware of the product itself. It is also the effect that an advertisement want to achieve—try hard to get readers know the good features of a product to attract their desire. Therefore, if we want to emphasize some part of a clause, we can place it at the beginning of a sentence. The other marked Themes in this advertisement also have the same effect. 5. In this advertisement, there are 9 clause plexes which contain the hypotactic or embedding clause. So it can be analysed further. Next, I will try to analyse the Theme structure of one of them for an example: There are 52,000ventilation holes so that the heat and humidity are Theme 1 Theme2 ventilated in order to maintain the normal variation range of the contact temperature. III. Cohesion According to Thompson (1996:147), cohesion refers to the linguistic devices by which the speaker can signal the experiential and interpersonal coherence of the text, and is thus a textual phenomenon: we can point to features of the text, which。
