【考題】(2004年天津完形)I realized strength and courage aren't always______in medals and victories,but in the struggles we overcome.

A.devotes to B.sticks to C.refers to D.1eads to

Key:D devote oneself to(=be devoted to)獻身于,;stick to堅持;referto提及;參考;它們都不合句意。lead to中的to為介詞,該句為強調句型,即Sleeping late in the morning leads to being late for work的強調形式。

A.1oved B.cared C.devoted D.a(chǎn)ffected

14.a(chǎn)t present=now/at the present time

for the present暫時(shí);眼前

up to/until the present直到現在

三、經(jīng)典句型

15.without短語(yǔ)without air,water and sunlight相當于:If there were no air,water and sunlight這個(gè)虛擬條件從句。

當虛擬語(yǔ)氣表示與現在事實(shí)相反時(shí),從句的謂語(yǔ)動(dòng)詞用“過(guò)去式(be的過(guò)去式用were)”,主句的謂語(yǔ)動(dòng)詞用“would/could/should+動(dòng)詞原形”構成。 ..

we human beings could not survive without all the plants and animals around us。

如果我們周?chē)鷽](méi)有植物和動(dòng)物,人類(lèi)就不能生存。

This kind of animal can live many days without food or water

這種動(dòng)物沒(méi)有食物和水也能生存許多天。

We can't live without food and water.我們離開(kāi)了食物和水不能生存。

解題警示:

在肯定句中,當介詞without后有兩個(gè)以上賓語(yǔ)時(shí),賓語(yǔ)間的連詞用or;在否定句中,則用and.

16. It won't be…before...用不了(多長(cháng)時(shí)間)就會(huì )……

沒(méi)等他有時(shí)間沖進(jìn)房子救那個(gè)孩子,房子就倒了。

解題警示:

從屬連詞before最基本的意思是“在……之前”。但在具體的句子中,譯法多種多樣,可譯為“……才……”;“……就……”;“還沒(méi)有……就……”;“沒(méi)等……就……”。before引導的狀語(yǔ)從句中不能使用表示將來(lái)的will。

四、詞餒辨析

17.common/usual/ordinary/normal

這四個(gè)詞(特別是前三個(gè))有時(shí)有通用的情況,但各自還是有各自的側重點(diǎn):

common意為“普遍的、常見(jiàn)的、共有的”,具有時(shí)常發(fā)生、出現頻率高、范圍廣的含義; ’

usual意為“通常的、一貫的、平常的”,指在某一地方、某一時(shí)間或某人身上平時(shí)常見(jiàn)的;

ordinary意為“普遍的,平凡的”,主要指人平凡或事物合乎常規,并不特殊,沒(méi)有什么突出特點(diǎn);

normal意為“正常的,常規的”,指在正常范圍之內。

解題警示

common強調“普遍性”和“范圍”,usual強調“常規性”,表達“時(shí)間”方面的概念。

18.no longer/not...a(chǎn)ny longer/no more/not…any more

no longer=not…any longer不再(現在與以前不同)

no more=not…any more二者都有“不再”的含義

解題警示:

在表示“(時(shí)間上、動(dòng)作或狀態(tài)持續上)不再”時(shí),常用no longer,較少使用no more

在表示“(數量上、動(dòng)作反復上)不再”時(shí),常用no more.

五、語(yǔ)法要點(diǎn)

19.直接引語(yǔ)和間接引語(yǔ)(復習)(略)(見(jiàn)第1講和第2講)

六、交際用語(yǔ)

20.原因和結果(Causes and effects):

Why…? Because/As/Since….

Because of...,I…. If…,then….

As a result of.… It follows that….

It will use…. It will lead to…. ’
