替代詞，就是在日常學習中所用的代詞或量詞。針對學生們常見的一些練習和考題， 總結了一下幾種特殊替代用法：

　　it 在句中作形式主語或形式賓語的替代用法

　　1. it作形式主語可以代替句中的動詞不定式、動詞-ing分詞或一個句子。

　　It is important for us to learn English well. (it替代不定式to learn English)

　　It is no use making such an apology to us Chinese. ( It 替代動詞-ing分詞 making such an apology)

　　It is happy for her parents that she is well now. (it 替代句子that she is well now)

　　2. it作形式賓語可以代替句中的動詞不定式，此時句中的謂語事由某些特殊動詞 (如：findthinkfeel等)充當的。

　　I find it impossible to finish so much work in such a short time. (it 替代不定式to finish so much work)

　　that this在句中的替代用法

　　1、 that

　　A: Im going to wear my new jeans to her party.

　　B: You cant do that. (that替代to wear my new jeans to her party這一事情)

　　2. this

　　this 在介紹某人或某物時，指的是靠近自己的一方。

　　A: Hi, Mr. Smith, This is my friend, Bill.

　　B: Nice to meet you, Bill.

　　C: Nice to meet you, Mr. Smith.

　　This 在電話用語中指的是自己。

　　A: Hello, may I speak to Miss Li?

　　B: This is Miss Li speaking. (我就是李女士)

　　which、that 、who、whom在定語從句中的替代用法

　　1. which 在句中放指物的先行詞后或整個句子后，引導限定性定語從句或非限定性定語從句。

　　She said I was lazy, which isnt true.( which替代句子 She said I was lazy)

　　This is the pen which was bought by my father. (which替代的是 the pen)

　　2. that在句中放先行詞后，引導限定性定語從句。既可指物，也可指人。

　　The book that she borrowed from the library was lost. ( that替代的是The book)

　　The man that with a knife in his hand is a murderer. (that替代的是The man )

　　The pants are too small for me, Can you show me another pair? (因為another后面只能跟單數可數名詞，故而這里用pair代替，意為a pair of pants)

　　如果沒有another時，則可用ones替代。

　　The red pants are too small for me. Can you show me the blue ones. (此處ones替代的是pants)

　　同樣，當遇上不可數名詞時，也要用相應的一些量詞來代替one 的概念，或用相應的量詞復數來代替ones的概念。

　　The paper is too small for the little girl to paint on, please give her another piece.(因為有a piece of paper)

　　Im so hungry that this slice of chicken isnt enough. Could you give me 3 more slices?(代替的是3 more slices of chicken.)

　　更多例句(請注意下面兩句的細微差別)

　　1) A: Look! There are many bottles of milk on the desk.

　　B: Yes, and which one do you like best? (此處用one的原因是A句中已經出現bottles of milk, 所以可以代替one bottle of milk)

　　2) A: There is much milk on the desk.

　　B: Yes, but which bottle bag do you like best? (此處A句中心詞為milk,因為milk 前面不能用one 來直接修飾，而只能用bottle或bag 來代表數量，可以說a bottle of milk a bag of milk)

　　某些名詞所有格也可以作替代詞

　　如：

　　1) A: Where is Jeanie?

　　B: Oh, she is at Marys. (這里的Marys代替的是Marys house)

　　2) Yesterday Toms father was ill, now he is at the doctors. ( 這里的doctors代替的是doctors room 或doctors clinic)
