Some utterances of imperative clauses have directive force—they impose obligations. Others have permissive force—they extend permissions. The dominant view is that this difference in force is not accompanied by a difference in semantic content. Drawing on data involving free choice items in imperatives, I argue that the dominant view is incorrect.

力量与选择

一些祈使句的表达具有指导性——它们强加了义务。其他人有许可的力量——他们扩展权限。主流观点认为，这种力量的差异并不伴随着语义内容的差异。根据涉及命令式中自由选择项的数据，我认为主流观点是不正确的。
