结构指的是句子的基本结构,表达法所指内容极为广泛,概括地讲,它指英文句子中词和短语的正确形式以及词与词,词与短语的正确搭配。这里主要讲解有关结构的命题,即英文句子的基本构成形式。
基本句子结构常考题型及解题要点
一般来讲,所考的有关句子结构的题目都比较简单,通常是正常词序的简单句和复合句,即主语-谓语-宾语或主语-系词-表语两种基本词序。倒装句、省略句、强调句试题也时有出现。但所占比例很小。
基本句型
(1)简单句 主- 谓- 宾
主- 系- 表
(2)复合句 主句 +连词 +从句
连词 +从句 ,主句
(3)并列句 句1 + 连词 + 句2
基本概念
(1)有主语、有谓语方可称为句子,否则为短语。
(2)主句和从句必须有连接词衔接。连接句可在两个句子中间,亦可放置于句首。
解题要点
(1)寻找谓语动词或系动词以确定主谓结构
(2)寻找连接词以确定句子结构
(3)分别检查主句和从句的主谓结构
