在今天的長(zhǎng)城游中，大家盡管問我任何問題，不要拘束。

feelfree是英語(yǔ)口語(yǔ)中一個(gè)常用表達(dá)。若有人讓你feelfreetodosomething,就是讓你無(wú)需拘束，只管按照自己的意愿去做某事。e.g.A:CanIuseyourbathroom?我可以用一下你的衛(wèi)生間嗎？B:Yes,feelfree.可以，請(qǐng)隨意。Languagepoints2.AsfarasIknow,therearenoman-madeobjectsasbigasthis.

在喜馬拉雅山脈之中，海拔在7000米以上的高峰有50多座，8000米以上的有16座，著名的有南峰、希夏邦馬峰、干城章嘉峰?！跋柴R拉雅”在藏語(yǔ)中就是“冰雪之鄉(xiāng)”的意思。這里終年冰雪覆蓋，一座座冰峰如倚天的寶劍，一條條冰川像蜿蜒的銀蛇。其中最為高聳的則是位于中國(guó)和尼泊爾邊界上的珠穆朗瑪峰，它以高達(dá)8844.43米的高度，是世界最高峰。

珠穆朗瑪峰(Qomolangma)，簡(jiǎn)稱珠峰，又譯作圣母峰，尼泊爾稱為薩加馬塔峰，也叫“埃非勒斯峰”（Everest），位于中華人民共和國(guó)和尼泊爾交界的喜馬拉雅山脈之上，終年積雪。高度8844.43米，為世界第一高峰，中國(guó)最美的、令人震撼的十大名山之一。

珠峰所在的喜馬拉雅山地區(qū)原是一片海洋，在漫長(zhǎng)的地質(zhì)年代，從陸地上沖刷來(lái)大量的碎石和泥沙，堆積在喜馬拉雅山地區(qū)，形成了這里厚達(dá)3萬(wàn)米以上的海相沉積巖層。以后，由于強(qiáng)烈的造山運(yùn)動(dòng)，使喜馬拉雅山地區(qū)受擠壓而猛烈抬升，據(jù)測(cè)算，平均每一萬(wàn)年大約升高20～30米，直至如今，喜馬拉雅山區(qū)仍處在不斷上升之中。1953年5月29日，34歲來(lái)自新西蘭的登山家埃德蒙·希拉里（EdmundHillary）作為英國(guó)登山隊(duì)隊(duì)員與39歲的尼泊爾向?qū)Уぴ觥ぶZ爾蓋TenzingNorgay一起沿東南山脊路線登上珠穆朗瑪峰，是紀(jì)錄上第一個(gè)登頂成功的登山隊(duì)伍。1960年5月25日，中華人民共和國(guó)人首次登上珠穆朗瑪峰。他們是王富洲、貢布（藏族）、屈銀華。此次攀登，也是首次從北坡攀登成功。1960年，我國(guó)首次登上地球之顛的3名英雄。1975年5月16日，日本人田部井淳子從東南山脊路線登上了珠穆朗瑪峰，是世界登山運(yùn)動(dòng)史上第一個(gè)踏上地球之巔的女性。1975年5月27日，中國(guó)登山隊(duì)的藏族女隊(duì)員潘多成為世界上第一個(gè)從北坡登上珠穆朗瑪峰的女性。2008年5月8日，中國(guó)登山隊(duì)圣火傳遞珠穆朗瑪峰突擊隊(duì)員，成功地把圣火從8300米突擊隊(duì)營(yíng)地傳遞到了珠穆朗瑪峰峰頂，創(chuàng)造了人類奧運(yùn)歷史上的奇跡。自讀文章，在書中劃出重點(diǎn)、疑點(diǎn)后，翻譯下列短語(yǔ)。先獨(dú)立完成，后小組商議。1.最危險(xiǎn)的山峰

includefreezingweatherconditionsandheavystorms.更加嚴(yán)峻的困難包括極冷的天氣狀況和巨大的風(fēng)暴。 1）difficulty既可作可數(shù)名詞也可作不可數(shù)名詞，在此用作可數(shù)名詞。作可數(shù)名詞時(shí),difficulty通常用作復(fù)數(shù)，表示具體概念，即：各種各樣的“困難；難題；難事”。例如：Peoplelearninganewlanguagemayfacesomedifficulties.人們學(xué)習(xí)一門新的語(yǔ)言時(shí)可能會(huì)遇到一些困難。Ifyouhaveanydifficulties,youcancallmeforhelp.如果你遇到任何困難，給我打電話求助好了。 作不可數(shù)名詞時(shí)，difficulty可譯作“困難；艱難；辛苦；費(fèi)勁”，例如：Hehadgreatdifficultyinfindinganewjob.

他找新的工作費(fèi)了很大勁。 .Wefoundthehousewithoutdifficulty.

我們輕而易舉地找到廣那座房子。2）include表示“包括；包含”，是一個(gè)及物動(dòng)詞。例如：Doesyourpriceofthebikeincludethislight?你們的車價(jià)包含這盞車燈嗎？ 3.Itisalsoveryhardtotakeinairasyougetnearthetop.

相當(dāng)于makeourdreamscometrue其中動(dòng)詞achieve表示“（通過努力）實(shí)現(xiàn)；取得；獲??；達(dá)到（夢(mèng)想、成績(jī)、成功、目的)”等。例如：Heachievedgreatsuccessinashorttime.他用很短的時(shí)間取得了極大的成功。LinTaoachievedverygoodexamresults.林濤考試取得了很好的成績(jī)。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(yǔ)從句，一般不與并列連詞but連用。如：Mr.Wangwillcomeontimeeventhough
