Conventionally indirect requests refer to contextual preconditions necessary for its performance as conventionalized in the language (He Wenting 2012, p。 10)。 According to Liu Guohui (2008) conventionally indirect requests express the illocution via fixed linguistic conventions established in the speech community。 Concerning conventionally indirect strategy we can find that there are suggestory formula and query-preparatory under Blum-Kulka’s sub-categories of conventionally indirect strategy。 This kind of strategy is widely adopted by the westerners。 The interrogative sentence patterns are extensively used under this category in order to show the speakers’ indirectness and politeness。来*自~优|尔^论:文+网www.youerw.com +QQ752018766*

Unconventionally indirect requests partially refer to the object depending on contextual clues (He Wenting 2012, p。 10)。 Also, Liu Guohui (2008) proposes that unconventionally indirect requests require the hearer to compute the illocution from the interaction of the locution with its contexts。 Strong hint and weak hint can be found under the category of unconventionally indirect strategy。 This kind of request strategy adopted by the speaker usually means to show his or her intention indirectly which also give the hearer room and freedom by not pointing out the intention directly。 The sentence structure adopted by the speaker is usually declarative sentence pattern instead of interrogative sentence pattern。
