句中makesitmoredifficultforchildrentoconcentrateorshow为make复合结构。其中it作形式宾语，真正的宾语是后面的动词不定式。[用法总结](1)make＋it＋形容词/名词＋that从句①Susanmadeitcleartomethatshewishedtomakeanewlifeforherself.苏珊清楚地跟我表明她希望为自己创造新的生活。(2)make＋it＋形容词/名词＋todo不定式②Theheavyrainmadeitimpossibleforustogoout.大雨使得我们无法出去。(3)常用于这种句型的动词还有：think，consider，find，feel等。③HeconsidereditimportantforhimtolearnspokenEnglishwell.他认为学好英语口语对他来说是重要的。④IfinditnousearguingwithBillbecauseheneverchangeshismind.我发现与比尔争辩没有用，因为他不会改变主意。[巩固内化]单句语法填空/同义句转换①Hedidn’tmake____________clearwhenandwherethesportsmeetingwouldbeheld.②Peopleinthewestmakeitarule____________(buy)Christmaspresentsfortheirrelativesandfriends.③Ithinkitisagoodhabittogetupearlyinthemorning.→Ithink________________togetupearlyinthemorning.④Wefindthatitiseasytogetalongwithhim.→Wefind____________________________．ittobuyitagoodhabititeasytogetalongwithhim2．Itistheseskillsthatenableustodeveloplifelongfriendships.(教材P15)正是这些技能才使我们能保持终生的友谊。[句式解读]

句中“Itis...that”为强调句型。其基本结构为“Itis/was＋被强调部分＋that/who＋其他成分”，本句中被强调部分为theseskills。[用法总结]

(1)强调句型的基本结构：Itis/was＋被强调部分＋that/who＋句子其他部分。①Butrulesalonedon’tsecureanorderlysociety.Itisthepeoplewhoobeytherulesthat(who)matter.但是制度本身不能保证一个有序的社会，遵守规则的人才是重要的。(2)一般疑问句的强调句型：Is/Wasit＋被强调部分＋that/who＋句子其他部分？②WasitthreeyearsagothathewenttoAmericaforfurtherstudy?他是三年前去美国深造的吗？(3)特殊疑问句的强调句型：疑问词(被强调部分)＋is/was＋it＋that＋句子其他部分？③Whenwasitthatyougotpromoted？你是什么时候升职的？(4)not...until...结构的强调句型：Itis/wasnotuntil...that...④Itwasnotuntilneartheendoftheletterthatshementionedherownplan.直到将近信的结尾她才提及了自己的计划。[名师提醒](1)在强调句型中It本身没有实际意义，但不能被其他词代替；被强调部分可以是主语、宾语和状语等；被强调部分指人时，可用that/who，其他情况一律用that。(2)判断是否是强调句型的方法：把Itis/was和that去掉，看句子的结构及语意是否完整，若完整，则为强调句型；若不完整，则不是。[巩固内化]
