【正确答案】In the two ways of asking for time, I would assume that the speech made by the first people is a direct speech act while the other one's speech is an indirect one. The first people directly asks for time in a casual way, while the other one indirectly inquires time by using the question “请问您戴表吗?” denoting the implicature that what he wants to know is not whether I wear a watch but time. Therefore, the first person seems a little impolite or even rude by using the word “哎” to attract my attention. On the contrary, the second one uses an appropriate pragmatic strategy and presents his strong communicative competence. He uses “不好意思，打搅下下” to attract my attention and establish a friendly atmosphere and implies that he wants to know the time with a question “请问你戴表了吗? ”
Perhaps the crucial distinction in the use of these two types of speech acts is based on the fact that indirect commands or requests are simply considered more gentle or more polite in our society than direct commands. And why they are considered more polite is based on some complex social assumptions.
