成人二语者在建立非局域性句法关系的时间进程中，其中介语语法机制虽然也会激活 ＷＨ 成分并将其作为变量储存在临时记忆中，但却不能基于连续循环操作为中间空位构建出心智表征，这完全迥异于英语本族语的语法表征和处理模式。就 ＷＨ 移置而言，本研究所获得的行为数据模式显示：中介语句子处理更多依助于词汇语义信息，而对结构信息的利用程度较为有限，从而在一定程度上支持中介语具有浅层表征的假设。文章认为，尽管移置性在近期被视为自然语言的基本属性，但由于中介语语法并不遵从结构依赖原则，因此在以累加方式即时处理二语句子的时间进程中，成人二语者无法为 ＷＨ 成分建构出结构化的层级表征，而其母语特异性对构建中间空位表征并无实质影响。

During the time course of establishing non-local syntactic relationships,the adult L2 learners’ interlanguage mechanism would also activate WH elements as variables and maintain their storage in the temporary memory, but would fail to construct mental representation for the intermediate gaps by way of successive cyclycity. This leads to the formation of contrasts between native representation and interlanguage representation. In terms of WH-dislocation, the present study obtains results through a self-paced reading design, which reveals the following behavioral pattern:sentence processing in interlanguage relies more on lexical semantic information, whereas less on structural information, thereby lending support to the Shallow Representation Hypothesis. Although displacement, as the inherent property of natural languages, receives crucial emphasis in recent theoretical inquiry, interlanguage grammar still lacks structural dependency, which well accounts for the lack of structural representation for WH elements and the insubstantial effects from L2 learners’ native language background.
