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。Languagepoints1.Feelfreetoaskmeanythin2.AsfarasIknow,therearenoman-madeobjectsasbigasthis.

據(jù)我所知，再沒有像它這樣大的人造物體了。asfarasIknow是一個固定的表達方式，還可以說sofarasIknow，意思是“據(jù)我所知”。例如：AsfarasIknow,Jack’sgottwinsisters.就我所知，杰克有一對孿生姐妹。They’renotcomingtoday,sofarasIknow.他們今天不來了—就我所知是這樣的。2.AsfarasIknow,thereare3.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。3.theMingGreatWall明長城4.Evenmoreseriousdifficulties

includefreezingweatherconditionsandheavystorms.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”。4.Evenmoreseriousdifficult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，給我打電話求助好了。 例如：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。作不可數(shù)名詞時，difficulty可譯作“困難；艱難；辛苦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？ 2）include表示“包括；包含”，是一個及物動詞。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)。5.Thespiritoftheseclimber2)achieveourdreams

相當(dāng)于makeourdreamscometrue其中動詞achieve表示“（通過努力）實現(xiàn)；取得；獲?。贿_到（夢想、成績、成功、目的)”等。例如：Heachievedgreatsuccessinashorttime.他用很短的時間取得了極大的成功。LinTaoachievedverygoodexamresults.林濤考試取得了很好的成績。2)achieveourdreams相當(dāng)于make一寫出下列單詞的比較級和最高級1.fortable3.big4.happy5.cheap6.many7.difficult8.little
