1.Subject:The subject of a sentence is the person, place, thing, or idea that is doing or being something. 先談 句子結構(sentence structure)
●句子既然以主詞為主，我們「聽讀說寫」英文句子時，當然就以主詞為主。主詞的變化，例如Mr. Chang(名詞) is a good teacher. He(代名詞) is a good teacher. Teaching(動名詞) is his job. To teach successfully(不定詞片語) is his goal. How to teach successfully (子句) needs more attention. It(虛主詞) is raining. There(虛主詞) is an excellent teacher in this school.
Generally (but not always) pronouns stand for (pro noun) or refer to a noun, an individual or individuals or thing or things (the pronoun's antecedent) whose identity is made clear earlier in the text.
代名詞可以具備任何意義(They can mean almost anything)，因此，讀到代名詞時，要清楚知道該代名詞代替什麼意思(When you see a pronoun in a sentence, you must make it clear what, or who, it does mean.)，或代替文章中那個名詞？
1.人稱代名詞(personal)，區分為主格與受格，例如 I/me(我), we/us(我們), you/you (你), you/you(你們), he/him(他), she/her(她), they/them(他們)
2. 指示代名詞(demonstrative)，例如this, that(單數), these, those(複數)，例句如This is my car. That will be fine. That’s OK. What’s that?
3.不定代名詞(indefinite)，例如it, anybody, anyone, anything, everybody, ever, none, everything, nothing, somebody, someone, something，例句如Anyone can do it.
4.疑問代名詞(interrogative, ask questions)，例如when, where, who, whose, which, what等，例句如Who is it? Whose car is this? Which do you want?
5. 關係代名詞(relative)，例如that, when, where, who, which, what，例句如The problem is that I can’t do it. I am the man who called you yesterday.
The reflexive pronouns (which have the same forms as the intensive pronouns) indicate that the sentence subject also receives the action of the verb.
The reciprocal pronouns are each other and one another.
