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。出国留学网雅思栏目为大家带来“雅思阅读句子结构分析”，希望大家能有所收获!
雅思阅读中五大句子结构的讲解主要从句型特点、例句讲解两个方面给大家分享了如何从雅思阅读中的长难句中提取出五种基本句型结构，也就是主干信息的方法，希望对大家雅思考试阅读练习有帮助。
一、主语+谓语(S+V)：
这类句子有一个共同特点，即句子的谓语都能表达完整的意思。谓语动词是不及物动词，后面可以跟副词、介词短语、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。

(剑8 Test 1Passage 1 )
句子结构分析：这句话的主语是They，谓语是based，宾语是their calendars，后面是on引导的介词短语。冒号后面的三个并列结构：the solar day, the lunar month and the solar ye...
