按照乔姆斯基的约束论,A、B、C三原则不是后天习得而是天生的。针对部分研究显示儿童遵循A原则和C原则而违背B原则,即B原则可能不是天生的问题,综述约束论及其发展,指出儿童违背B原则并不意味着其不是天生的。相反,试验显示儿童理解B原则的句法,而其违背B原则可能为语义或者语用方面的原因。 According to Chomsky’s theory of constraint, the three principles of A, B and C are not innate but innate. Some studies have shown that children violate the B principle by observing principles A and C, that is, the B principle may not be a natural problem. To sum up the theory of restraint and its development, it is pointed out that children’s violation of the B principle does not mean that they are not innate. On the contrary, experiments show that children understand the syntax of the B principle, whereas the violation of the B principle may be a semantic or pragmatic reason.
