英語中 it，one，that 的用法區分，看似簡單，用錯太丟人了

1. it 指代前面提到過的同一事物，即同名同物

例圖：I left my key in my drawer, but today it is gone.(it 指上文提到過的key)

我把鑰匙放抽屜裡，可是今天不見了。

2. one 泛指與前面的名詞同類的另一事物，即同名異物，其複數形式是ones

例圖: I don`t like this type of computer. Could you show me a better one?(one 指computer，但不是上文提到過的)

我不喜歡這種款式的電腦，能給我拿一個更好一點的嗎？

3. that 特指的名詞與前面的名詞只是同一類，但並非同一個，即同名異物。that可以代指可數名詞單數和不可數名詞，但只能指事物，不能指人。其複數形式是those，those只能代替可數名詞複數，可以指人或物。

例圖：The weather in Guangzhou is hotter than that in Beijing in summer.(that指the weather. 但不是同一地區的)

夏天，廣州的天氣比北京熱。

4. one 與that 都指代同名異物，但one是泛指，相當於a/an+名詞，所以one所指代的名詞修飾語一般為a/an/some/any.

例如： A chair made of steel is stronger than one made of wood.

而that為特指，相當語the+名詞。所以that指代的修飾語一般是 the/this/that.

例如：The water in the cup is hotter than that in pot.
