1、从属结构概念如果一个语法结构含有同一层次甚至高一层次的结构为其直接成分，这种现象叫做“从属”。例如：themanwithaguninhishandthemanwhowasholdingaguninhishand从属结构可以是词组（主要是介词词组），也可以是限定分句、非限定分句或无动词分句。名词词组：名词词组＋介词词组名词词组：名词词组＋关系分句限定从属分句限定从属分句就是以限定动词词组作谓语动词的从属分句。例如：Whatcausedthefireisstillamystery.Themanwhodidtherobberyhasbeencaught.Sinceth

4、词后可以接that从句充当宾语，如exceptthat,butthat,savethat,inthat：Ipreferhisplantoyours,inthathisismorepractical.WeknownothingabouthersavethathersurnameisJones.That从句作同位语同位语从句用于解释说明先行词的内容，通常由that引导，除此外还可用whether,what等疑问词。例如：Wecametothedecisionthatwemustactatonce.Hemadeaproposalthatthemeetingbepost

5、poned.thefactthat…是较常见的同位语结构，例如：Thefactthathehasnotbeenseenrecentlydisturbseverybodyintheoffice.Hewasheldresponsibleforthefactthathisdoghadbittenhisneighbor.Itisimpossibletodisguisethefactthatbusinessisbad.Thefactthat常置于句首充当主语，也可置于某些不能直接跟that从句的介词或动词之后充当宾语。That的省略问题That从句充当主语、补语、同位语时

6、，一般不省略。That从句充当宾语时，如果前面的动词为常用动词，that往往可以省略，如果前面的动词为较正式、不常用的动词，that不宜省略。例如：Shesaid(that)shewasfeelingbetter.Thejudgeheldthatthechild'sinterestsinthiscasemustcomefirst.当一个句子有多个that从句充当宾语时，第一个that可以省略，但后面的that不能省略。例如：Hetoldme(that)hewouldgofishingtomorrowafternoonandthathewouldinviteMar
