问主从复合句和从句有什么区别呢？

复合句、复杂句的区分i. 简单句（simple sentence）主语+谓语+宾语i love my mom.i go to school everyday.ii. 复合句（ compound sentence）beijing is in the north and nanjing is in the south.(特点：when two independent clauses, or complete sentences are joined together, they form one compound sentence.复合句是由两个独立的句子组合在一起构成的。例句中，有下面两个完整并且独立的句子组成：beijing is in the north.nanjing is in the south.iii. 复杂句（complex sentence）my uncle, who is seventy years old, works on a farm.(特点：when an independent clause and a dependent clause are joined together; they form one complex sentence.复杂句是由一个独立的句子加一个从句构成的。)china is a country that its history is very long.china is a country. (独立句子)that its history is very long (从句)iv. 复杂句+复合句（compound sentence+ complex sentence）studying english is important because a lot of jobs needpeople know english; moreover, learning english helpspeople understand other country’s culture.整体看，这是一个由 moreover 连接的复合句，前后两句都在谈论学英语的重要性， 两个独立完整的句子。但第一句话中又包含了一个由because 引导的从句。你知道英语中最常用的句型是什么句子吗？ 复杂句 (complex)。my american teacher said,” the most common sentence pattern is complex sentence, because language reflects life.”为什么不是复合句呢？she said, “how many things are equal in our life?”

含有从句的句子，称其为主从复合句。如：Where there is a will ,there is a way .其中where there is a will 就称为从句。
