16.本單元的語法重點是學習it的另一用法：作為強調句型的引導詞。
1. 用于強調句中除謂語以外的任何一成分，其句型為It + is／was+被強調部分+that(強調部分指人也可用who／whom)十句子其他成分。如:
It was Tom who／that met your brother in the park yesterday．(強調主語Tom)
It was your brother whom / that Tom met in the park. (強調賓語your brother)
It was in the park that Tom met your brother yesterday.(強調地點狀語in the park)
It was yesterday that Tom met your brother in the park. (強調時間狀語yesterday)
使用強調句型應注意下列幾點：
①無論被強調部分是什么，總是用his／was．．．that．．．(強調指人的主語that可換成who，指人的賓語可換成whom)
It was they who (that) built the house last year.是他們去年蓋了這座房子。
②強調主語時，謂語動詞必須和原主語一致。如：
It is I who am to blame.是我應受到責備。
③注意此句型與定語從句的區別。如：
It was in this factory that my father used to work.
我父親過去是在這個廠工作的。(強調句型)
It was this factory that my father used to work in.
這就是我父親工作過的那家工廠。(定語從句)
另外，it還經常用于構成下列句型，在學習過程中應多加注意。如：
① It's... since .... It's five years since we last met.
從我們上次見面至今已有五年了。
② It's... before .... It won't be long before we meet again
不久我們會再見面的。
2．在學習過程中，我們經常遇到one，it, that作代詞的用法要注意分析、比較它們的用法，辨別它們的不同處。
在英語中為了避免重復上文的某個名詞，常用心one或that來代替。讓所指的事物和前面提到的事物是同一件事物，所以讓代表的名詞屬于特指的。
I bought a knife and lent it to him.我買了一把小刀，借給他了。
I drank some ice tea but it made me more thirsty.我喝了點涼茶，卻更渴了。
one所代表的名詞和前面所提到的名詞只是同一類，并非指同一個，而且指同類中的任何一個，不是只指其中某一個。所以one所指的名詞屬于不定的，單數用one，復數形式為ones，而且one所替代的名詞必須是可數名詞，不能替代不可數名詞。
Mary needs a new dictionary. She is going to buy one.
瑪麗需要一本新字典，她打算買一本。
This watch is too expensive, show me a cheaper one, please.
這塊表太貴了，請給我較便宜的一塊。
I don't want these green apples; I want the red ones.
我不想要這些綠蘋果；我要紅的。
that和one都是指同一類事物而不是指同一個事物，但that替代有定冠詞的名詞。為特定的，而且還可以替代不可數名詞。
The cost of oil is less than that of gas.石油的價格低于天然氣的價格。
The voice of a woman is sweeter than that of a man.
女人的聲音比男人的聲音悅耳。
