本論文藉由分析兩位三歲兒童和他們母親的對話來探討兒童行使請求(request)的情形。文中的討論主要涵蓋了三個層面。分別是兒童行使請求時採取的策略，使用的語言形式，以及運用的互動知識(interactional knowledge)。結果發現，兩位兒童行使請求時會採用下面的策略：指明一特定的動作、指明想要取得的物體、指出自已的需求及間接暗示。此外，他們利用以上的策略行使請求時所使用的語言形式有所不同；而這些差異似乎間接反映出這兩位兒童的一些對話或是人際互動的知識(conversational or interpersonal knowledge)影響了他們請求時所使用的語言形式。因此，本論文推論兒童在三歲左右或許已經知道了一些互動知識，而這些互動知識會影響他們在對話中如何請求。

This study aims to explore children’s requests in mother-children conversation based on dyads of two three-year-old children and their mothers. Three aspects about children’s requests in daily conversation are concerned: (1) the means or strategies children depend on to convey their request intents; (2) the formal or linguistic elements children employ to realize their request intents; and (3) the conversational or interpersonal skills children may have acquired as they are requesting. With a careful examination over the collected conversations, it is found that children at the age of three tend to demonstrate their requests through the following means. First, children indicate a specific action they intend their hearers to do in their utterances. Second, children request for a desired object by indicating literally the target objects, or information about the target object, e.g. adjectives or quantifiers. Thirdly, they indicate their self-want to have their hearer fulfill their desire. The last means children employ to request is hinting. They indirectly convey their request intents, and their hearer can infer the intended act. In addition, children usually use different formal elements to manifest their requests. For example, their requests for a specific action were found to be conveyed with imperatives, imperatives with sentence-final particles, or imperatives with A-not-A tags. Further investigation on the formal varieties of children’s requests reveals that some conversational or interpersonal factors may play a role in how children convey their request intents, e.g. cooperativeness, social status, conversational topic. The findings, therefore, show that children at the age of three have probably been aware of some conversational or interpersonal knowledge and the knowledge may affect their performance of requests in conversation.
