long research paper for a degree
A long, formal paper that a student writes to finish a university degree, especially a master's or PhD.
用法模式：
to write a thesis on [topic]
常见错误：
Learners often confuse *thesis* (the whole long research paper for a degree) with *thesis statement* (a single sentence that gives the main idea of an essay). In academic writing classes, when teachers say "Write a thesis statement," they usually do NOT mean to write a full thesis.
近义词
dissertation (Very close in meaning; in many universities this is the usual term for a doctoral thesis, especially in American English.)
反义词
exam (An opposite kind of degree requirement: a test with questions instead of a long research paper.)

main argument of a text
The main idea or claim that a writer or speaker wants to explain and prove, usually in one clear sentence.
用法模式：
the thesis of [a book / an essay] is that [clause]
常见错误：
Learners sometimes think *thesis* here means "topic" or "subject". A thesis is not just what the text is about; it is a specific claim or opinion that the writer wants to prove. They also sometimes write very broad or factual statements as theses, instead of arguable claims.
近义词
central argument (Emphasizes that this is the key line of reasoning, not just any idea in the text.)

proposition put forward and defended
An idea or claim that a person says is true and then tries to support with reasons and facts.
用法模式：

Learners sometimes use *opinion* when they mean a carefully argued *thesis*. An opinion can be simple and personal; a thesis in this sense suggests a more serious claim that should be supported with reasons or evidence.
