阅读是雅思考试中非常重要的部分，很多考生阅读成绩不是很理想，在这方面考生们既要加强自己的词汇量和语法知识，同时也要掌握一定的技巧规律。留学群雅思栏目为大家带来“2016雅思阅读常考句子结构分析”，希望大家能有所收获!
雅思阅读五大常用句子结构剖析，主要从各句型特点、例句讲解以及两个方面讲解，告诉大家如何从雅思阅读的长难句里提取出5种基本句型，希望可以对大家的雅思阅读考试有所帮助。
第一个：主语+谓语
共同特点是句子的谓语能够表达出完成的意思，谓语动词是不及物动词，后面可以跟副词、介词短语以及状语从句等。
例如：An accident that occurred in the skies over the Grand Canyon in 1956 resulted in the establishment of the Federal Aviation Administration (FAA) to regulate and oversee the operation of aircraft in the skies over the United States, which were becoming quite congested. (剑8 Test 1Passage 2 )
句子结构分析：这句话的主干是An accident resulted in the establishment of the Federal Aviation Administration (FAA)。主谓结构式An accident resulted，后面跟得是介词短语。That引导定语从句修饰An accident，to regulate and oversee…表示目的，which引导非限制性定语从句修饰the operation of aircraft。
第二个：主语+系动词+表语
常见的系动词有两类：一类表情况——be，look，smell，taste，sound等;一类表变化——get，grow，become，turn，go等。
例如： The revolutionary aspect of this new timekeeper was neither the descending weight that provided its motive force nor the gear wheels (which had been around for at least 1,300 years) that transferred the power; it was the part called the escapement. (剑8 Test 1Passage 1 )
句子结构分析：这句话的主干是主系表结构，不过有两个并列的表语。主语是The revolutionary aspect，系动词是was，表语是neither the descending weight nor the gear wheels。第一个that引导定语从句修饰weight，括号里的句子做插入语，是对gear wheels的补充说明，that引导定语从句修饰gear wheels，分号后面是一个简单的句子。
