一般地说,印欧语比汉语更多使用语法手段,表达焦点敏感算子与焦点词语的语义关系方面恰恰相反,印欧语用语音表达,汉语反而用句法表达,算子浮动到尽可能接近焦点的位置,而且还要受到成分统制和区域性条件等句法限制。这说明汉语也受句法制约,虽然不表现在反身代词约束等方面,至少表现在焦点关联方面。 In general, Indo-European languages ​​use more grammatical means than Chinese. Contrary to the semantic relationship between focus-sensitive operators and focus words, Indo-European languages ​​use expressions instead of Chinese to express sentences. Operators float as close as possible The focus of the position, but also subject to composition control and regional conditions and other syntax restrictions. This shows that Chinese is also subject to syntactic constraints, although not reflected in the reflexive restraint and other aspects, at least in the focus of relevance.
