高考英语语法复习名词性从句知识讲解练习一、主语从句主语从句，是把一个句子里的主语展成句子，也就是一个句子里的名词（主语）扩展成例句（That+主语+谓语+宾语）+谓语+宾语。比如看这个简单句，LiHuaisagoodstudent.(李华是一个好学生）把他扩展为主语从句ThatLiHuahelpsotherstudentsstudyingisagoodstudent.(李华帮助其他同学学习是一个好学生）。看下面例句1.ThatheteachedstudentsinXINJIANG（主语从句）isvoluntary.(他去新疆支教是自愿的）2.Thatheinsistedtostudyatnight（主语从句）isourexample.(他坚持在晚上学习使我们的榜样）3.Thathecutthetreestomakechopsticks（主语从句）isfalse.(他砍伐大树来制作筷子是错的）4.Thatheimprovedstudent'sgrade（主语从句）ishisresponsible.(他提升学生的分数是他的责任）5.Thatherepairedcomputers（主语从句）isefficient.(他修电脑是高效的）注意:主语从句还有一个情况，就是用形式主语it，这种情况通常把主语从句放在谓语的后面，通常指谓语较短时，结构为it+谓语+that+主语从句1.Thatlighttravelsinstraightlinesisknowntoall.(众所周知光以直线传播）Itisknowntoallthatlighttravelsinstraightlines.2.Thathecatchedthethieffinished.(他抓住小偷结束了）Itisfinishedthathecatchedthethief.3.Thatfarmersharvestedabundantcropsisreported.(农民收货大量庄稼被报道了）Itisreportedthatfarmersharvestedabundantcrops.二、表语从句表语从句就是把系动词之后的表语变成句子,比如Peterseemedcold（彼得感觉很冷）我们把它展为表语从句ThePeterseemedthathefeltcoldinairconditionroom.(彼得在空调屋里感觉很冷）看下面例句表语从句1.Thebeeseemedthatitpollinatefortheflowers(蜜蜂看起来是给花朵授粉）2.Johnremainedthathefeltconfusedafterlisteningtheinterpretation.2,(约翰在听完解释后仍旧很困惑）3.Thepoliticaffairwasthatgovernmentintroducedpolicywhichsupporttheagriculture.(政治事件是政府颁布了一个支持农业的政策）4.Thepeopleseemedthattheyfeltscaredafterlookinghorriblemovies.(人们在看完恐怖电影后看起来很害怕）5.Itsoundslikethatheadmitsthemistakes.(这听起来他承认了错误）三、宾语从句宾语从句是把宾语展成一个句子，通常是主语+谓语+that(宾语从句）,比如Peterpromisedathing（彼得承诺了一件事）我们把它展为宾语从句Peterpromisedthathewasgoingtogivehisyongerbrotheragift（彼得承诺他要给他弟弟一个礼物）看下面例句1.Peterdeterminedthatheisgoingtowinthechampioninthematch.(彼得决意他将在比赛中赢得冠军）2.Johnwishthathewillgetagoodgradeintheexam.(约翰希望他在考试中能取得一个好分数）3.Maryconcludethatthethiefisgoingtoescapefromthesoutheast.(玛丽推断出小偷将从东南方逃跑）4.Janeguessthathewillcompletecookingwithin1hours.(简猜他将在1小时内做完饭）5.Peterpromisedthathewillreachthedestinationassoonaspossible.(彼得承诺他将尽快到达目的地）四、同位语从句同位语通常是对前面抽象名词的解释说明，同位语从句的先行词一般有conclusion,theory,question,promise,problem,fact,truth等。一般修饰某一个句子的名词后面加引导词Thefactthatdarkchocolateislittebitteristrue(黑巧克力是苦的这个事实是真的）Hegivedapromisethathewillgiveupsmokingwithhalfyears.(他给了一个承诺他将在半年内戒烟）Theygiveainterpretationthatsellerdon'tundertakethebackfreight(他们做出解释卖家不承担退货运费）Theytellatruththatfarmersdon'tapplyfertilizerforthecrops.(他说出了一个事实农民没有给庄稼施肥）Heintroduceaproblemthatinsectsofthisareacannotbeeliminatedcompletely.(他介绍了一个困难这个区域的昆虫无法彻底被消灭）2
