我们先来说说写作的五重境界：

第一：简单句的罗列和堆砌
S1+V1…S2+V2…S3+V3…
第二：并列连词连接简单句
S1+V1…and/or/but/also/whereas S2+V2…
第三：复合句
S1+V1…which/that/where/when etc./because/if/in order that etc. S2+V2…
第四：独立主格
S1+V1…，S2+V2…
S1+V1…，S2+V2ing/V2ed
第五：非谓语动词作修饰成分
S1+V1…，S1+V2…
S1+V1，V2ing/V2ed…

如果你觉得上面的这堆“公式”看起来有些枯燥难懂的话，那么不妨给你举两个例子，同样的话，用不同的句子说，看看有什么不同的效果。
