（15）指示代詞
指示代詞是拿來指示某物的，又稱形容詞性代詞，因為如果在它后面加上一個名詞的話，它就成為形容詞了。只有在單獨用的時候，它才是指示代詞，如：
1. This is now the mango season.（代詞）
2. This golden mango is my favourite.（形容詞）
1. Each of the pupils has his own bag.（代詞）
2. Each boy has his own bag.（形容詞）
1. Have you read any of his books？（代詞）
2. Any school boy knows it.（形容詞）
1. this、that、these、those 的用法
a. this 是指近處的東西，其復數為 these；而 that 是指遠處的東西，其復數為 those。
① This is a shirt；that is a collar.
② These are mine，and those are yours.
b. 兩個名詞分別指示時，前者用 that（復數用 those），后者用 this（復數用 these）。
①Work and play are both necessary to health；this（= play）gives us rest，and that（= work）gives us energy.
②Dogs are more faithful animals than cats；these（= cats）attach themselves to places，and those（= dogs）to persons.
c. 為避免重復用同一名詞，可用 that（復數用 those）來代替前面說過的名詞。
①The air of lowlands is not so cool as that of hills.
②The ears of a horse are shorter than those of a rabbit.
d. 又可用 this、that 來代表前面的 clause 或 sentence。
①You suppose him to be a miser，but that is certainly a mistake.
②You paid your debts；and this is quite sufficient to prove your honesty.
e. that 不僅可以代表前面的 clause 或 sentence，而且可以加強其意義，但須用 and that 的形式。
I must consult with him，and that at once.
He will come，and that soon.
I studied English literature when I was young，and that at Oxford.
f. this、that 可以用來歸納既述的幾個名詞，但須與 all 連用。
①But all this was nothing to what followed.
②What is all that done for？
2. one、ones 的用法
a. 代表前面說過的不定的普通名詞，就用 one（復數時用 ones）。
Have you a knife？Yes，I have one（= a knife）.
但在 one 之前如有形容詞時，就應再加冠詞。如系復數的 ones，就可用 some 代替冠詞。
Have you any knives？Yes，I have a sharp one. 或 Yes，I have some sharp ones.（但如果沒有形容詞時，則連名詞也不要，只說 Yes，I have some. 就行了。）
b. 代表前面說過的“不定的普通名詞”要用 one，但代表前面說過的“特定的單數普通名詞”，就要用 it 才對。換句話說，即是 it 用于“同名同物”的場合，而 one 用于“同名異物”的場合。
Is this knife yours？No，it（= the knife）is my brother’s.（同名同物）Mine is the one（the knife）on the table.（同名異物。）
①Have you ever seen an elephant？（不定的普通名詞）
No，I have never seen one.
②Is this elephant from India？（特定的普通名詞）
Yes，it is；it is very gentle.
c. one 如果是指一般人（men in general）的時候，后面的所有格就要用 one’s，如系限定的時候，就用 his、her 等。
① One must be careful not to break one’s word.
②To love one’s enemies is a Christian duty.
但 any one、some one、every one、each one、no one 等的場合就要接 he 或 his 了。
① Every one loves his mother.
②I saw some one in the distance，but could not tell in what direction he was going.
3. another、other 的用法
a. another 是 an + other 所構成的，含有兩個意思：①另外的（different）。②也是一個（also one）。但都不指固定的事物。
①This shirt isn’t nice；show me another.（different）
②He is a fool，and his wife another.（also one）
b. one...the other 的用法。
在兩件事物之中，隨便取一件說 one，其余一件則說 the other。
Both my brothers are abroad，one in England and the other in America.
c. the one...the other 的用法。
在二者之中，說其一及其二，而 the one 更常用以指其次所提出之事物，不一定照原說的次序。
①Virtue and vice are before you；the one（指前者的 virtue）leads to happiness，the other（指后者的 vice）to misery.
②The bee and the snake draw material from the same plant. The one（指后者的 snake）transmutes it into deadly poison；the other（指前者的 bee）into delicious honey.
注意：the one...the other 又可作形容詞用，如“With the one hand he held aloft the child and with the other（hand）he was making for the shore. ”。
d. others 及 the others 的用法。
有冠詞和無冠詞意思不同，others = other people，即“別人”，而 the others = the rest，即“其余的人”。
①Do as others do，and few will laugh at you.
②One of them was an American，but the others were Englishmen.
e. each other 及 one another 的用法。
二者之間用 each other，三個以上之間就要用 one another。
①Both of them helped each other.
②The three men helped one another.
f. one after another 及 one after the other 的用法。

① One falsehood after another falls off of itself.
②He raised one of his hands after the other.
4. each 的用法
① Each of them wanted to try.
②They each have a book.
但“They have a book each ”就是副詞，而“Each boy has a book”就是形容詞。
5. either 和 neither 的用法
either 是“二者中任何一個”，而 neither 是“二者皆非”。
① Either will do.
②I know neither of his parents.
6. both 和 all 的用法
雙方就說 both，三者以上就用 all。
① Both of my parents are tired out.
②They were both tired out.
③They both were tired out.
① All of the chickens are dead.
②They are all dead.
③They all are dead.
7. some 和 any 的用法
some 用于肯定，any 用于否定、疑問及條件句。
①Are there any staying at the hotel？（疑問）
②Yes，there are some.（肯定）
③No，there are not any.（否定）
④Give me a sheet of paper if you have any.（條件）
8. none 的用法
none 原是 no one 合攏來的，單復皆可，現今通常用作復數。又 no = not any 或 not a，而 none = no + Noun。
①Have you a book？No，I have none.（= no book）（單數）
②Have you any sisters？No，I have none.（= no sisters）（復數）
③ None but the brave deserve the fair.（復數）

b. such = such men

c. such as = those who

same 前可以加 the、this 或 that 用
