Step5Languagepoints

1.Oneoftheworld'smostdangeroussportsismountainclimbing,...

“oneof+the+形容詞的最高級(jí)+復(fù)數(shù)名詞”,意為“最……之一》。如：

MissWangisoneofthemostpopularteachersinourschool.

王老師是我們學(xué)校最受歡迎的老師之一。

2.Itisalsoveryhardtotakeinairasyougetnearthetop.

Itis+adj.+todosth.,it作形式主語放在句首，而把真正的主語放在句尾。常

用于此句型的形容詞有important,difficult,dangerous,necessary,useful,

possible等，用來對todosth.進(jìn)行說明。此句型可以轉(zhuǎn)換成Todosth.is+時(shí)

e.g.ItisimportanttostudyEnglishwell.學(xué)好英語很困難。

IfsverydifficulttoclimbQomolangma.攀登珠穆朗瑪峰很難。

3.Evenmoreseriousdifficultiesincludefreezingweatherconditionsandheavy

storms.

difficulty既可作可數(shù)名詞也可作不可數(shù)名詞。作可數(shù)名詞時(shí)通常用復(fù)數(shù)，表示

具體概念，即：各式各樣的“困難，難題，難事”，如：

He'shavingfinancialdifficulties.

他正手頭拮據(jù)。

作不可數(shù)名詞時(shí)，譯作“困難，艱難，幸苦”，如：

Shehadgreatdifficultyinunderstandinghim.她很難理解他說的話。

4.Thespiritoftheseclimbersshowsusthatweshouldnevergiveuptryingtoachieve

ourdreams.

give叩意為“放棄"，后面可以接名詞、代詞或形式作賓語。

注意：如果其賓語是名詞，那么名詞可以放在give和up之間，也可以放在up

之后；如果其賓語是代詞，那么代詞只能放在give和叩之間。如：

8

Myunclewantstogiveupdrinkingwine.我叔叔想戒酒。

AlthoughEnglishisn'teasytolearn,Iwon'tgiveitup.

雖然英語不易學(xué)，但我不會(huì)放棄。

5.Whydosomanypeopletrytoclimbthismountaineventhoughitisdangerous?

eventhough用作從屬連詞，意為“即使；盡管“，相當(dāng)于evenif,引導(dǎo)讓步狀語

從句，一般不與并列連詞but連用。如：

Mr.Wangwillcomeontimeeventhoughitrains.

盡管下雨，但王老師會(huì)按時(shí)來。

對于鯨魚你知道多少？

鯨的體型是世界上存在的動(dòng)物中最大的，鯨是終生生活在水中的哺乳動(dòng)物，

對水的依賴程度很大，以致它們一旦離開了水便無法生活，鯨形狀像魚，鼻孔在

頭的上部，用肺呼吸。體長可達(dá)三十米，是現(xiàn)在世界上最大的動(dòng)物。

鯨為適應(yīng)水中生活，減少阻力，它們的后肢消失，前肢變成劃水的漿板。身

體成為流線型，酷似魚。因而它們的潛水能力很強(qiáng)，小型齒鯨可潛至100-300米

的水深處，停留4?5分鐘，長須鯨可在水下300.500米處待上1小時(shí)，最大的齒

鯨-抹香鯨能潛至千米以下，并在水中持續(xù)2小時(shí)之久。
