是共用成分,还是承前省略成分

就汉语中几个谓词性短语连用且前有相同修饰语或主语的句子的单复句归属问题展开讨论。得出前有相同主语的一般为复句,前有句中相同修饰语的为单句,句首有相同修饰语的为复句。引入“象似性”（iconicity）中的“距离象似原则”和“数量象似原则”对此加以解释。最后为几个谓词性短语连用且句中无共同修饰语的句子的单复句划界找到了形式上的依据。

Common Constituent,or Zero Anaphoric Constituent?

In the paper, we talk about some sentences which include several linked predicate phrases. These phrases have preposed common subjects or modifiers. We conclude that the sentence that has common subject is complex one, that has middle common modifier is simple one, and has first-place common modifier is complex one. We try to introduce distance iconic and number iconic principles of iconicity to explain this. In the end we found some formal basis for whether these sentences are simple or complex.
