在今天的長城游中，大家盡管問我任何問題，不要拘束。

feelfree是英語口語中一個常用表達。若有人讓你feelfreetodosomething,就是讓你無需拘束，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，請隨意。Languagepoints3.theMingGreatWall明長城“明長城”是指明朝時期為了防御北方游牧民族的騷擾，歷時一百多年在北部地區(qū)修筑的軍事防御工程。這段長城東起遼寧虎山，西至甘肅嘉峪關(guān)，從東向西橫貫多個省、直轄市、自治區(qū)，全長約8850千米，是現(xiàn)存歷代長城遺跡中最完整、最堅固的。4.Evenmoreseriousdifficultiesincludefreezingweatherconditionsandheavystorms.更加嚴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,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)一門新的語言時可能會遇到一些困難。Ifyouhaveanydifficulties,youcancallmeforhelp.如果你遇到任何困難，給我打求助好了。 作不可數(shù)名詞時，difficulty可譯作“困難；艱難；辛苦；費勁”，例如：Hehadgreatdifficultyinfindinganewjob.

他找新的工作費了很大勁。 .Wefoundthehousewithoutdifficulty.

我們輕而易舉地找到廣那座房子。2）include表示“包括；包含”，是一個及物動詞。例如：Doesyourpriceofthebikeincludethislight?你們的車價包含這盞車燈嗎？ 5.Thespiritoftheseclimbersshowsusthatweshouldnevergiveuptryingtoachieveourdreams.這些登山者的精神向我們表明：我們絕不應(yīng)該放棄實現(xiàn)自己夢想的嘗試。1）giveupdoingsomething的意思是“放棄做某事；半途而廢”Hegaveuplearningathirdlanguageafterhegotthejob.他找到工作之后就放棄了對第三門語言的學(xué)習(xí)。一寫出下列單詞的比較級和最高級betterbestmore～most～biggerbiggesthappi
