本文反駁橫越式位移的假說。從理念上講，該假說提出的分叉式位移軌道很武斷，而且與公認的句法特徵刪減的操作原理相左。從句法操作上講，在同一領域內對下位成分進行多項位式提取是不可能的。不可能的原因是多項位式位移首先需要諸項目合為一體；其次需要遵守循序漸進的流程。這兩個要求自然而然地排除了橫越式位移的可能性。我們發現，如果兩個成分要作同類型的位移，其中一個的起點必須成分統治另一個的起點。從實證角度上看，有論據表明橫越式句型的成分提取僅起始於第一個並列項而已。

This paper argues against Across-The-Board movement. Conceptually, the stipulation of a forking chain is ad hoc, and incompatible to our well-recognized feature checking operations. Computationally, no multiple extraction operations from sub-constituents to the same damain are possible. The impossibility is accounted for if we realize that multiple movement chains need to form a cluster and that movement obeys the cyclicity condition. The combination of the two considerations rules out ATB movement. I found that if two elements undergo the same type of movement, the launching site of one element must c-command the launching site of the other element. Empirically, there is evidence to show that the extracted element of ATB constructions is originated in the first conjunct only.
