在我国,关键期假设理论对外语的学习有很大的影响,尤其对外语学习的起始年龄。大多数人认为学习外语的年龄越小越好,可是,在外语的学习中,除了年龄因素外,还有其他的影响因素,年龄不能够起决定性的作用。因此,要正确理解关键期假设在外语学习中的作用。 In our country, the hypothesis theory of critical period has a great influence on foreign language learning, especially the starting age of foreign language learning. Most people think that learning a foreign language is as small as possible. However, in the study of foreign languages, besides age, there are other factors that affect the age. However, age can not play a decisive role. Therefore, it is necessary to correctly understand the role of critical period hypothesis in foreign language learning.
