一、句子过长的原因英语句子之所以会过长，主要是因为以下原因：1.修饰语多：英语句子中可以有多个形容词、副词、介词短语等来修饰名词或动词，导致句子变长。 2.并列结构：句子中出现并列的主语、谓语、宾语、表语、定语、状语等，也会使句子变长。 3.从句嵌套：句子中包含一个或多个从句，并且从句中又包含另一个或多个从句，这会让句子更加复杂。 二、分析长难句的步骤1.找出谓语动词：谓语动词是句子的核心，它决定了句子的时态和语态。 2.分清主从结构：如果句子中有从句，要分清主句和从句，以及从句的类型。 3.分析从句：如果从句是名词性从句（主语从句、宾语从句、表语从句、同位语从句），要找出从句的连接词和句子的成分；如果从句是形容词性从句（定语从句），要找出先行词和关系词。 4.翻译句子：按照句子的成分和结构，把句子翻译成中文。 三、长难句分析实例1.主语从句：That she was chosen made us very happy.（她被选中了，这使我们很高兴。） 2.宾语从句：We believ
