不及物动词的两种类型--非作格动词（有潜在主语）和非作格动词（有潜在宾语）--在二语习得的早期阶段可能并不存在，两者在句法上都表现为非作格动词。这一观点，在这里被称为非重复性陷阱假说，为英语、日语和汉语中各种看似无关的句法现象提供了一个优雅的发展解释。目的语输入、自然语言连接规则的结构约束以及学习者母语的语言特性在中介语语法的词汇和句法成分的重组过程中形成阶段。虽然非母语语法最初可能会超越不确定性假设（Burzio，1986; Perlmutter，1978）和Theta赋值假设（Baker，1988）的一致性，但在后来的发展阶段，一些语法仍然可能符合自然语言的规范。
The distinction of two types of intransitive verbs—unergatives (with underlying subjects) and unaccusatives (with underlying objects)—may not exist at early stages of L2 acquisition, both being syntactically represented as unergatives. This idea, referred to here as the Unaccusative Trap Hypothesis, provides an elegant developmental account for a variety of seemingly unrelated syntactic phenomena in L2 English, Japanese, and Chinese. Target language input, structural constraints on natural language linking rules, and linguistic properties of a learner's L1s shape stages in the reorganization of the lexical and syntactic components of interlanguage grammars. Although nonnative grammars may initially override the structural constraints postulated as the Unaccusative Hypothesis (Burzio, 1986; Perlmutter, 1978) and the Uniformity of Theta Assignment Hypothesis (Baker, 1988), at later developmental stages some may still achieve conformity with the norms of natural languages.
