Through the study, the author finds that the advertisers use different kinds of mood adjuncts, modal auxiliaries to claim different degrees of certainty and uncertainty so as to make the advertisements convincing as well as revealing; the advertisers use the present tense to turn to the readers intermittently and to make implicit evaluations of their products/services along the way; use multiple means to realize the imperativeness in advertisements and they address the readers as "you" in advertising textual world to create the pull for the readers to get into the real situation.
