此句中用了單個動詞“completed”，意思比較明確，在此則不可採用短語動詞“carried out”。因為短語動詞為非正式語言，“短語動詞往往不止一種含義，而且常常難以確定，寫專業論文時往往要用意義比較明確的單個動詞來代替……”[5]carry out就有“實施(計畫)”、“舉行(義務、約定)”、等含義。
iwould like to thank my supervisor professor xxx withoutwhosemost helpful instructions and guidance， the completion ofthis thesiswould have been impossible.
此句中的“iwould like to”不宜縮寫為“i’d like to”。英語縮寫詞“一般用於非正式文體。”[6]iwould like to express my deep gratitude to my supervisorprofessorxxx for spendingmuch time reading and improving thisthesis.
iwould also like to extendmy sincere thanks tomr. xxx forevaluatingmy thesis and offering valuable input.
finally， iwould like to give thanks tomy classmatexxx forfindingmemany valuable references in the course ofmywriting.
此“致謝”中的三個句子相互平行，結構相似，均採用的是“iwould like to do sth. to sb. fordoing sth.”這一句子結構。
帶有平行結構的句子常用於正式文體[7]，以表強調。
3.掌握“致謝”內容的實質
儘管英語畢業論文“致謝”的篇幅不大，但其內容安排要求對其排列有序、段落層次分明、理由實在具體篇例如:i am most grateful to my supervisor professor xxx withoutwhosemosthelpful instructions andwarm encouragement this the瞫iswould nothave been finished.
i am also grateful tomy classmates xxx and xxx for theirtime spentwithme discussing questions concerned.
and lastly， special thanks go tomy parents andmy brotherwhohave always supportedme inmy endeavors to finish this thesis.
此“致謝”的對象包括導師、同學和家人，其感謝的順序是先導師、再同學、後家人，符合“致謝”寫作的對象排序。
my sincerestgratitude goes tomy supervisorprofessorxxx.
she has helped me in choosing a suitable topic and guided methroughmy thesiswriting.
my special thanks also go to xxx and xxx， my goodfriends. they have recommended tome some usefulbooks relatedtomy thesis.
finally， aword of appreciation to the school offoreign lan瞘uages for allowing me to use the reference room and computerroom formy research.
本“致謝”採用了分段感謝。第一段感謝導師幫助“我”選出論文的合適題目並指導完成論文;第二段感謝好朋友推薦給“我”一些與論文有關的有用書籍;最後一段感謝外國語學院允許“我”使用資料室和計算機室進行研究。“致謝”對象各成一段，內容明確、層次分明。
i would like to thank my supervisor associate professorxxx， who has givenme the considerable academic help and con瞫tant supportduringmy thesiswriting.
iwould also like to thank my classmates xxx and xxx，who have spent time discussing questions concerned with me andofferedme kind advice about the thesis.
finally， iwould like to thank xxx library， which has pro瞯idedmewith useful reference needed inmy thesis.
該“致謝”中感謝理由都與完成論文有關，而且具體實在。嚮導師致謝是因為在“我”論文寫作期間導師提供了很大的學術幫助和不斷的支持。向同學致謝是因為他們花時間跟“我”討論論文中的有關問題並提出了好的意見。向xxx圖書館致謝是因為它給“我”提供了有關論文的所需資料。
三、佐證示例
以下“致謝”對象具體、文體正式、格式規範，實事求是，態度誠懇。比較符合西方英語學位論文“致謝”的寫作這一具體要求:“lauding one’s professors， and humbling one’s own e瞗forts are considered inappropriate.”[8]acknowledgementsiwould like to expressmy heartfeltgratitude tomy supervisorprofessorxxx forher encouragement， guidance and advice tomethroughout thewriting of this thesis.
