lift，raise，rise這幾個(gè)動(dòng)詞都有“由低處向高處舉起或升起”的意思，但它們的含義和使用情況有所不同。lift是指用體力或機(jī)械力把某物從地面舉到一定的高度。

16.本單元的語(yǔ)法重點(diǎn)是學(xué)習(xí)it的另一用法：作為強(qiáng)調(diào)句型的引導(dǎo)詞。

1. 用于強(qiáng)調(diào)句中除謂語(yǔ)以外的任何一成分，其句型為It + is／was+被強(qiáng)調(diào)部分+that(強(qiáng)調(diào)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(qiáng)調(diào)主語(yǔ)Tom)

It was your brother whom / that Tom met in the park. (強(qiáng)調(diào)賓語(yǔ)your brother)

It was in the park that Tom met your brother yesterday.(強(qiáng)調(diào)地點(diǎn)狀語(yǔ)in the park)

It was yesterday that Tom met your brother in the park. (強(qiáng)調(diào)時(shí)間狀語(yǔ)yesterday)

使用強(qiáng)調(diào)句型應(yīng)注意下列幾點(diǎn)：

①無(wú)論被強(qiáng)調(diào)部分是什么，總是用his／was．．．that．．．(強(qiáng)調(diào)指人的主語(yǔ)that可換成who，指人的賓語(yǔ)可換成whom)

It was they who (that) built the house last year.是他們?nèi)ツ晟w了這座房子。

②強(qiáng)調(diào)主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞必須和原主語(yǔ)一致。如：

It is I who am to blame.是我應(yīng)受到責(zé)備。

③注意此句型與定語(yǔ)從句的區(qū)別。如：

It was in this factory that my father used to work.

我父親過(guò)去是在這個(gè)廠工作的。(強(qiáng)調(diào)句型)

It was this factory that my father used to work in.

這就是我父親工作過(guò)的那家工廠。(定語(yǔ)從句)

另外，it還經(jīng)常用于構(gòu)成下列句型，在學(xué)習(xí)過(guò)程中應(yīng)多加注意。如：

① It's... since .... It's five years since we last met.

從我們上次見(jiàn)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(huì)再見(jiàn)面的。

2．在學(xué)習(xí)過(guò)程中，我們經(jīng)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(yǔ)中為了避免重復(fù)上文的某個(gè)名詞，常用心one或that來(lái)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(mǎi)了一把小刀，借給他了。

I drank some ice tea but it made me more thirsty.我喝了點(diǎn)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(gè)，而且指同類中的任何一個(gè)，不是只指其中某一個(gè)。所以one所指的名詞屬于不定的，單數(shù)用one，復(fù)數(shù)形式為ones，而且one所替代的名詞必須是可數(shù)名詞，不能替代不可數(shù)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(mǎi)一本。

This watch is too expensive, show me a cheaper one, please.

這塊表太貴了，請(qǐng)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(píng)果；我要紅的。

that和one都是指同一類事物而不是指同一個(gè)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(shù)名詞。

The cost of oil is less than that of gas.石油的價(jià)格低于天然氣的價(jià)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。
