Question

英语中的复合句和复杂句有什么区别？

Answer 1

复合句是两个或两个以上的简单句组成，每个简单句都有主谓，句子句子之间由连词连成；而复杂单句再长，也是一个句子，只有一个主语，一个谓语，只是在定语状语补语上修饰成分多，显得长而已，对于长的复杂句，抓住主语谓语是关键，回头在看修饰成分，就不难看懂

Answer 2

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 need
people know English; moreover, learning English helps
people 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?”
