The purpose of this paper is to investigate agreement-feature checking and English root infinitives in child language from the perspective of Minimalist Program. To explain this apparent derivation from the target adult gram- mar, researchers have elaborated two main models. One is the Tense Omission Model and the other is the Truncation Model. Wexler (1994) proposes in the former that an optional infinitive clause arises when the child leaves the tense feature underspecified in a given clausal represen- tation. Rizzi (1993/1994) proposes in the latter that the Root Infinitive reduces structures that result from the option of truncating structures at different levels of the clausal architecture. A further expectation would be that nominative Case is not assigned properly if AgrP is not yet projected. In the Minimalist Program, T inherits Agree-feature from C, but root infinitive clauses don`t have TP. Therefore, in children`s speech, functional projections are truncated below CP. The phenomena of early language acquisition reflects the process of acquiring functional categories as children grow.

Heinrich Bullinger and John Calvin agreed on a common doctrine of the Eucharist in 1549. They signed a mutual agreement in Zurich, includes 26 items:≪Consensus Tigurinus≫, which was published in Zurich and Geneva in 1551. The agreement between the Zurich and the Geneva branch of the Reformation is historically significant. On the one hand, the≪Consensus Tigurinus≫brought the unity of the Zwinglian Reformation and that of the Calvinist in Switzerland. This means to be a single Reformed Church. But on the other hand, the document was attacked by the Gnesio Lutheran Joachim Westphal, and it brought about the innocent occasion of the second sacramental controversy.
