二.課堂導學
同學們在學習的過程中可能遇到一些不懂得地方吧？課堂導學可以幫助你答疑解惑。
不定代詞(指人)
1. 不定代詞做主語，謂語動詞使用單數；
2. someone/somebody用于肯定句，通常指代“一個人”；
3. anyone/anybody 用于疑問句；
4. anyone/anybody;和no one/nobody 用于否定句；當anyone/anybody用于肯定句時，表示任何人；e.g. anyone needs water and air in the world。
不定代詞(指物)
something 通常用于肯定句，但也可用于一般疑問句；
nothing 表示“沒有什么東西” ，只能指物; 用what 進行提問；
none 表示“沒有一個事物或人”;用 how many/ how much提問；
注意：形容詞與something; anything; nothing連用時，要置于它們之后。
注意none, nothing, no one的區別: none 可以和of 連用，其它的不能和of連用; none 與all 反義。
none用法補充：none既可指人，也可指物，它只是指在一定范圍內，代替上下文已出現過的名詞。none可指沒有人或沒有東西，在句中作定主語或賓語。作主語時，謂語動詞可用單數,也可用復數。
nothing表示“沒有什么東西”，只能指物，不能指人，同時沒有任何限制。
no one（=nobody） 一般用來指人，使用時不受一定范圍的限制。
