摘　　要：二语句法的发展是按一定的顺序进行的。系动词be标注的是其指示语和补足语之间的局部关系,所以系动词be作为功能语类最早被习得。系动词的出现触发了T在二语句法中的建立。与系动词be相比,助动词"be"则有较多的语义和语法制约关系。时态是T的一个特征,过去时态标注涉及T和一个TP外的一个时间指称之间的非局部关系。指示语和中心语之间的一致关系所涉及的数量特征、人称特征等匹配关系仅仅是出于语法目的,但在概念意义上却无任何必要,所以对二语习得者来说比由时态算子表示的时态制约关系更难在大脑中建立。Second Language syntax develops regularly from one stage to another. Copular ＂be＂, which marks the local relation between its specifier and complement, will be acquired first before the auxiliary ＂be＂ which has more semantic and grammatical constrains. The copula ＂be＂ triggers the establishment ofT that has interpretable tense feature. And the specification of past tense involves the non-local relation between T and a temporal referent outside the TP. While the matching features involved in the non-local relation between the head and its specifier for Agree are only out of grammatical requirement, so the third singular person ＂-s＂ is more difficult to acquire than the past tense form that has been signified by a tense operator.
