代詞it與one有哪些區別

一、關于代詞 it

it指的是與前面已提到的事物為同一物，此時的it等于“the (this, that, my...)+名詞”。如：

He aimed at the bird and missed it. 他瞄準那只鳥卻沒打中。

He banded the box before mailing it. 郵寄前他把盒子用帶子捆扎好。

To affect a policy is to have an effect on it. 影響一項政策就是對該政策具有一種影響。

He brought out his dictionary and looked the word up in it. 他拿出詞典來查這個詞。

二、關于代詞 one

one 指的是與前面已提到的事物為同一類物，此時的one等于“a+名詞”。如：

Two heads are better than one. 兩人智慧勝一人；三個臭皮匠勝過諸葛亮。

另外，one 的前面根據需要可以有冠詞、物主代詞、指代詞等修飾（但 it 前面不可以這樣用）。如：

The task before us is not an easy one. 我們面臨的任務不輕。

The stuffed dog barks as if it is a real one. 這只狗標本叫起來像真狗似的。
