句子结构是英语语法的核心部分,它定义了单词如何组合成有意义的句子,以下是一些常见的英语句子结构:
简单句(Simple Sentence) :由一个主语和一个谓语构成,"She runs." 或 "The dog barks."
复合句(Complex Sentence) :包含至少一个从句,可以分为两种类型:名词性从句(Noun Clause)和形容词从句(Adjective Clause)。"Although it was raining, she went for a walk." 这个句子中,“Although it was raining”就是一个名词性从句。
复杂句还可以进一步细分为同位语从句(Appositive Clause)、定语从句(Attributive Clause)、状语从句(Adverbial Clause)等。“The book, which I borrowed from the library, is very interesting.” 这个句子中,“which I borrowed from the library”就是一个定语从句。
疑问句(Interrogative Sentence) :以疑问词开头,"Is it raining?" 或 "Where are you going?"
感叹句(Exclamatory Sentence) :以感叹词或特殊疑问词开头,"How beautiful the sunset is!" 或 "Why are you crying?"
只是基本的句子结构,实际上英语语法远比这要复杂,理解并掌握这些基本的结构是学习英语语法的关键。
