Step5Languagepoints

1.Oneoftheworld'smostdangeroussportsismountainclimbing,...

“oneof+the+形容词的最高级+复数名词”，意为"最……之一如：

MissWangisoneofthemostpopularteachersinourschool.

王老师是我们学校最受欢迎的老师之一。

2.Itisalsoveryhardtotakeinairasyougetnearthetop.

Itis+adj.+todosth.,it作形式主语放在句首，而把真正的主语放在句尾。常用于此句型的

形容词有important,difficult,dangerous,necessary,useful,possible等，用来对todosth.

进行说明。此句型可以转换成Todosth.is+

e.g.ItisimportanttostudyEnglishwell.学好英语很困难。

IfsverydifficulttoclimbQomolangma.攀登珠穆朗玛峰很难。

3.Evenmoreseriousdifficultiesincludefreezingweatherconditionsandheavystorms.

difficulty既可作可数名词也可作不可数名词。作可数名词时通常用复数，表示具体概念，即：

各式各样的“困难，难题，难事”，如：

He'shavingfinancialdifficulties.

他正手头拮据。

作不可数名词时，译作“困难，艰难，幸苦”，如：

Shehadgreatdifficultyinunderstandinghim.她很难理解他说的话。

4.Thespiritoftheseclimbersshowsusthatweshouldnevergiveuptryingtoachieveourdreams.

giveup意为“放弃。后面可以接名词、代词或v-i〃g形式作宾语。

注意：如果其宾语是名词，那么名词可以放在give和up之间，也可以放在叩

之后；如果其宾语是代词，那么代词只能放在give和up之间。如：

Myunclewantstogiveupdrinkingwine.我叔叔想戒酒。

AlthoughEnglishisn'teasytolearn,Iwon'tgiveitup.

虽然英语不易学，但我不会放弃。

5.Whydosomanypeopletrytoclimbthismountaineventhoughitisdangerous?

eventhough用作从属连词，意为“即使；尽管“，相当于evenif,引导让步状语从句，一般不

与并列连词but连用。如：

Mr.Wangwillcomeontimeeventhoughitrains.

尽管下雨，但王老师会按时来。

对于鲸鱼你知道多少？

鲸的体型是世界上存在的动物中最大的，鲸是终生生活在水中的哺乳动物，对水的依赖

程度很大，以致它们一旦离开了水便无法生活，鲸形状像鱼，鼻孔在

头的上部，用肺呼吸。体长可达三十米，是现在世界上最大的动物。

鲸为适应水中生活，减少阻力，它们的后肢消失，前肢变成划水的浆板。身体成为流线

型，酷似鱼。因而它们的潜水能力很强，小型齿鲸可潜至100-300米的水深处，停留4-5分钟,

长须鲸可在水下300-500米处待上1小时，最大的齿鲸-抹香鲸能潜至千米以下，并在水中持

续2小时之久。
