长难句

分析找主谓1.找谓语，定主语一般情况下，一个谓语动词对应其动作的发出者（主语），我们可以根据谓语动词的意义来确定其主语。当然句子里也可能会有并列谓语，由and,but,or等连接。2.提主干、去枝叶（即去掉三长两短一平行）：不管多长的句子，都是由非常简单的主干成分+修饰成分组合而成YanearnedherPh.DatPrincetonin2004_________returnedin2017.修饰1）三长：介词短语（prep+n）、非谓语(todosth,doingsth,donesth)、从句(连词+句子)2）两短：形容词、副词3）一平行：平行并列结构（含并列连词如and,but,or,so等）三长（1）介词短语：从介词开始到介词之后的第一个名词

例：(athome),(intheschool),(inthebeautifulpark)（2）从句：从关系词开始，到以下四种情况终止：（画出以下的从句和介词短语）①到句尾终止

例：Tomisastudentwhoworksextremelyhard.②到句中逗号为止

例：WhenIwasyoung,Ilistenedtotheradio.③到下一个修饰成分为止例：IwillinviteYaoMingwhowasatopbasketballplayertoBeijing④到下一个谓语动词终止例：YaoMinwhowasatopbasketballplayerisstudyinginShanghai.三长（3）非谓语动词：找出以下句子的非谓短语①Tomisastudentstudyinghard.②ToimprovemyEnglish,IoftenlistentoEnglishradio.--IoftenlistentoEnglishradiotoimprovemyEnglish.③Jackwalkedintothehall,wavingtotheaudience.④We,singingahappysong,runstoschool.两短（1）形容词（修饰名词的单词）位置：名词前a(beautiful)city

不定代词之后something(interesting)（2）副词（修饰形容词、动词、句子的单词）ly结尾平行：并列结构A...andB...（1）方法：先找B，再找A（2）原因：A,B中心词后常常有修饰成分（A离and很远，不好找，B很近），找到B后，再根据结构一致，含义结构相同找A（3）练习：找出以下句子的并列成分①Iliketheboxplacedonthedeskandtheflowersinyourhand.②Mr.Smithisakind,patientandknowledgableEnglishteacher.
