指示性言语行为可以从狭义与广义上加以定义,在表现形式上包括祈使句及其变体、非祈使句的特定话语(诤言类英语谚语、疑问句、及特定语用环境下的话语)。非祈使句的特定话语要置于语用环境下加以考察,以确定它们的具体言语行为类型。 Indicative speech acts can be defined in a narrow sense and in a broad sense. They include expressions of imperatives and their variants, and non-imperative sentences (verbal English proverbs, interrogatives, and discourses in specific pragmatic contexts). Specific language of non-imperative sentence should be placed under the pragmatic environment to examine to determine their specific types of speech acts.
