ive sentences. Informative statements are often labelled as true(truth) or false(falsehood). According to ’ s “ Cooperative Principle” (see Hu Zhuanglin et al., pp282283), one ought not to violate the “ Maxim of Quality” , when he is informing at all. ? When language is used to obtain information, it serves an “ interrogative function” . This includes all questions that expect replies, statements, imperatives etc., according to the “ indirect speech act theory” , may have this function as well, ., “ I’ d like to know you better.” This may bring forth a lot of personal information. Note that rhetorical questions make an exception, since they demand no answer, at least not the reader’ s/listener’ s answer. ? The “ expressive function” is the use of language to reveal something about the feelings or attitudes of the speaker. Subconscious emotional ejaculations are good examples, like “ Good heavens!” “ My God!” Sentences like “ I’ m sorry about the delay” can serve as good examples too, though in a subtle way. While language is used for the informative function to pass judgement on the truth or falsehood of statements, language used for the expressive function evaluates, appraises or asserts the speaker’ s own attitudes. ? The “ evocative function” is the use of language to create certain feelings in the hearer. Its aim is , for example, to amuse, startle, antagonize, soothe, worry or please. Jokes(not practical jokes, though) are supposed to amuse or entertain the listener。 my group member39。這就是 語(yǔ)篇( textual)功能 。這個(gè)純理功能稱(chēng)為
