當母語者與非母語者在進行溝通時，母語者通常會使用較為簡化的語言形式，此種語言形式研究者稱之為「調整語」。本文旨在探討在台灣的成人美語教室中，外籍教師針對不同程度的學生，使用調整語的情形，文中主要從「句法」與「言談功能」兩個角度分析外籍教師的語言使用。 有三位教授中、高級美語會話的外籍教師參與本研究，每位教師於不同層級的課堂各接受兩次錄音，總計收集到18小時的錄音語料，351頁的逐字稿，全數經過分析比較後，主要發現如下： (1) 外籍教師之語言平均句長並未隨著學生程度越高而有顯著增加。外籍教師在中級教室之平均句長為8.197，在高級教室為8.388，p>0.05。此結果顯示，當學生程度到達中級以上，「句長上的調整」似乎不再是外籍教師採用的調整方式。 (2) 外籍教師之語法正確率在兩個層級都非常高。外籍教師在中級教室之語法正確率為99.81%，在高級教室為99.79%，在兩個層級都僅有10個錯誤句子，透過錯誤類型分析，發現中級教室中出現較多句法層面上的錯誤，而篇章層面的錯誤則全出現在高級教室中。 (3) 外籍教師之言談功能會隨學生層級不同而有調整。外籍教師在中級教室中給予較多主動的語言輸入、提供較多的發問，主要功能為傳輸語言知識；在高級教室中，教師減低發言的比例，使用較多的回饋功能。 綜合以上研究結果發現，英語為母語之外籍教師在上課時面臨不同語言程度的非母語對話者有不同的語言調整方式，在中、高級程度的班級上，「句法上的調整」不再是外籍教師的主要考量，而轉向採用「語言功能上的調整」，在教學應用上，儘管隨著學生層級的增加，外籍教師減少了「主動語言輸入」功能，而採用較多的「語言回饋」功能，但整體而言，學生發言的比例仍然偏低（中級教室9.93%；高級教室12.15%），教師應給予學生更多的口語練習機會，採用更多的回饋機制，以增加學生之溝通能力。 / When addressing to non-native speaker, native speakers will modify his speech to what he thinks is simpler and easier for the non-native listener to comprehend. Such simplified register is referred to as “Foreigner Talk.” The present study aims to explore both the syntactic and discourse characteristics of FT in Taiwan’s adult English classrooms. Three measurements (1) syntactic complexity (2) grammaticality and (3) discourse functions are adopted to investigate if the interlocutor’s language proficiency affects the foreigner teacher’s language use. The data were collected from 18-hour recording of three English native speakers’ utterances in intermediate and advanced classrooms. The major findings of this study are summarized as follows: (1) In terms of syntactic complexity, the mean words per t-unit at both levels are very similar with 8.197 at the intermediate level, and 8.388 at the advanced level. The result of t-test (p>0.05) also indicates that no significant difference is found concerning the language complexity between the two levels. It is suggested that the adjustment of language complexity may only resort to students with lower proficiency. Once the student’s proficiency goes beyond a specific level, the length of teacher’s utterances will keep in a fixed range. (2) In terms of grammaticality, over 99.79% of the foreigners’ utterances are grammatical sentences in both language classrooms, showing that the foreigners’ language form is quite accurate. By analyzing the 20 ungrammatical utterances, it reveals that the foreigner teachers are more likely to utilize the syntactic adjustment for the lower level learners and conserve the discourse adjustment for the more advanced ones. (3) In terms of discourse functions, Sinclair and Coulthard’s model (1992) is modified to categorize the functions of the foreigners’ utterances. It is found that the distribution of the functions varies with the development of the students’ language ability. The foreigner teachers use significantly more initiation functions to the intermediate students and provide much more responsive functions for the advanced students. Based on the findings of this study, some pedagogical implications are addressed. It is suggested that teachers should pay more attention to their language use and consider if their adjustments of language really enhance language learning. In order to increase the learning potential, teachers are recommended to employ more judicious silence, to reduce the percentage of teacher-initiated utterances and to resist the temptation to interrupt. Also, teachers should realize that they are not only an instructor but also an interlocutor for their students at the same time. By realizing the dual roles as being a language teacher, the teacher can make language class less artificial and help learners to overcome the gap between communication in and outside the classroom.

本研究旨在探討台灣大學生英語被動語態的使用，並且探討台灣大學生是否理解英語被動語態在單句以及篇章的功能。本研究受試者為27位政大英語系大一作文班學生。受試者使用英語被動語態的語料則由三種不同類型的研究工具蒐集而來：中英單句翻譯，英文篇章選擇，與英文作文。 研究結果發現台灣大學生對於英語被動語態沒有完善的理解。受試者在單句翻譯的表現顯示當中文句子裡沒有中文被動提示詞時，受試者翻譯時容易使用錯誤的語態。此發現同時也點出受試者對於英語動詞種類以及英語語意角色這些和英語被動語態密切相關的概念相當陌生。在無法辨別句子裡動詞種類的情況下，受試者無法正確判斷句中名詞的語意角色，因而寫出錯誤的句子。然而，受試者在英文篇章選擇的表現顯示他們了解英語被動語態是一個能夠增進文章句子之間的連結以及一貫性的句型結構。而受試者在英文作文的表現也顯示了他們知道如何實際運用英語被動語態來建立自己文章中所要闡述的主題，並進一步強化文章整體結構。 為了進一步理解台灣大學生對於英語被動語態的知識如何形成，本研究也檢視了目前台灣國中以及高中所使用的英語教科書當中，對於英語被動語態的呈現方式以及介紹內容。本研究發現英語教科書對於英語被動語態的介紹多半侷限在此句型結構於單句以及句法的使用，而忽略了英語被動語態在篇章以及語意層面的功能。根據以上的研究發現，本研究亦提出了如何在英語被動語態的教學上加入篇章以及語意層面的介紹，以幫助台灣英語學習者學到更完整的英語被動語態的知識。 / The present study investigates the use of English passive voice by Taiwanese college students. The purpose is to see how Taiwanese college students use English passive voice on sentential and discourse level, and if they understand the functions of English passive voice from their performances. Twenty-seven college students participated in this study. And their uses of English passive voice were investigated with three different instruments, Single-sentence Translation, Passage Completion and English Compositions. The results of the analysis showed that Taiwanese college students do not have complete understanding on English passive voice. In Single-sentence Translation, the participants fail to recognize the correct voice in translating Chinese sentences when Chinese passive markers are removed. This finding points out that the participants do not have the knowledge of English verb types, their argument patterns, and semantic roles. Because they are unable to identify the type of English verbs in the sentences, they are not aware of the semantic roles of noun phrases accompanying the verbs in the sentences. As a result, they are unable to produce correct English passive sentences. In Passage Completion, however, the participants’ performances indicate they understand English passive voice is a useful device in facilitating the connections between the sentences and maintaining thematic progression of passages. In English Compositions, it is found that the participants demonstrated ways of using English passive voice that are not observed in the previous two research instruments. Their performances show that they know how to use this structure to facilitate the cohesion as well as coherence of their writings, and how to use English passive voice to establish the idea they want to elaborate on in the paragraph. To see how Taiwanese EFL learners build up their knowledge of English passive voice, English textbooks of junior high and senior high school are reviewed to see how this structure is presented. It is found that much emphasis is placed on the introduction of English passive voice on sentential and syntactic level, neglecting the introduction on discourse and semantic level. Based on the findings in the present study, it is suggested that the teaching of English passive voice include the introduction of this structure on discourse and semantic levels to help Taiwanese EFL learners gain a more comprehensive understanding of English passive voice.

中文可說是個篇章導向的語言(discourse-oriented language)，以篇章為其基本單位，數個中文子句不藉連接詞即可連結成主題串(topic chain)。當如此龐大的篇章單位翻譯成主語顯著的英文時，譯者會面臨的困難是，如何將主題串切割成數個英文句子。然而，此議題卻鮮少前人研究。因此，本論文試圖探討中文主題串英譯時的翻譯策略，並著重於斷句的影響因素。分析的語料來自漢英對照版的台灣光華雜誌以及翻譯教科書。為了瞭解翻譯策略，本研究分析中文的語意分段標記與資訊順序，並與譯文比較。分析結果顯示譯者在翻譯時會採用三種策略：反映段落標記(Reflecting the Markers)、建立語句關係(Establishing Textuality)、重整資訊(Rearranging Information)。第一個策略是將中文段落標記作為英譯斷句的依據。段落標記包括三類：主題的形式、連接詞、標點符號。第二個策略，建立語句關係，表示英譯斷句依據中文主題串各句子之間的篇章關係。第三個策略，重整資訊，表示透過增加、刪除、調換順序等方式調整原文的資訊。 / Chinese is considered a discourse-oriented language. The basic unit of the Chinese language is discourse-based. Several Chinese clauses can be linked together without any connectives to form a topic chain. When such a large discourse is translated into English, a subject-prominent language, translators may have difficulty deciding how to segment a Chinese topic chain into English sentences. However, little research has been done on this topic. The present study aims to explore translation strategies used in translating Chinese topic chains into English. In particular, the demarcation mechanism will be the focus. Chinese-to-English translation data from Taiwan Panorama, a Chinese-English bilingual magazine, and from translation textbooks are collected for analysis. The demarcation markers and information flow in Chinese are analyzed and compared to understand how they are treated in the English translation. Three strategies have been found: Reflecting the Markers, Establishing Textuality, and Rearranging Information. Reflecting the Markers is to reflect the Chinese boundary markers as English demarcation points. Boundary markers contain nominal references of topic, connectives, and punctuation marks. Establishing Textuality is to organize the Chinese topic chain based on the internal textual relationships. Rearranging Information is to add, delete, or reorder the information.
