Step5Languagepoints

1.Oneoftheworld'smostdangeroussportsismountainclimbing,...

“oneof+the+形容詞的最高級+復數(shù)名詞”，意為"最……之一如：

MissWangisoneofthemostpopularteachersinourschool.

王老師是我們學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.

進行說明。此句型可以轉(zhuǎn)換成Todosth.is+

e.g.ItisimportanttostudyEnglishwell.學好英語很困難。

IfsverydifficulttoclimbQomolangma.攀登珠穆朗瑪峰很難。

3.Evenmoreseriousdifficultiesincludefreezingweatherconditionsandheavystorms.

difficulty既可作可數(shù)名詞也可作不可數(shù)名詞。作可數(shù)名詞時通常用復數(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，譯作“困難，艱難，幸苦”，如：

Shehadgreatdifficultyinunderstandinghim.她很難理解他說的話。

4.Thespiritoftheseclimbersshowsusthatweshouldnevergiveuptryingtoachieveourdreams.

giveup意為“放棄。后面可以接名詞、代詞或v-i〃g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，也可以放在叩

之后；如果其賓語是代詞，那么代詞只能放在give和up之間。如：

Myunclewantstogiveupdrinkingwine.我叔叔想戒酒。

AlthoughEnglishisn'teasytolearn,Iwon'tgiveitup.

雖然英語不易學，但我不會放棄。

5.Whydosomanypeopletrytoclimbthismountaineventhoughitisdangerous?

eventhough用作從屬連詞，意為“即使；盡管“，相當于evenif,引導讓步狀語從句，一般不

與并列連詞but連用。如：

Mr.Wangwillcomeontimeeventhoughitrains.

盡管下雨，但王老師會按時來。

對于鯨魚你知道多少？

鯨的體型是世界上存在的動物中最大的，鯨是終生生活在水中的哺乳動物，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。體長可達三十米，是現(xiàn)在世界上最大的動物。

鯨為適應水中生活，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，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，最大的齒鯨-抹香鯨能潛至千米以下，并在水中持
