我用最简单的语言说,你有些眉目之后,想把具体的内容弄明白,一定再看看语法书.
句子的基本结构是：主谓宾（或许还有 补语、定语、状语、表语）要学会找句子主干.
从句子结构上分,可以将句子分为简单句、复合句和并列句.
简单句：有一套主谓宾的句子.如：It will not happen again.
复合句：包括主、从句两个部分.句子的某一个成分,主、宾、定、状或表语,是由一个句子充当的.
如果主语是有句子充当的,就是主语从句.如：That I am late for school will not happen again.宾语从句 如：Mr.Wang knew that I was late again.
定语从句：I was late for school,which is known to all.
状语从句：I was late for school again because John stopped me on my way to school.
并列句：就是句子有2套或者2套以上的主谓宾.A句 and/but B 句 的形式.
I am from China,and he is from the U.S.
