日本で生まれた日本人がいくら小学校から英語やったって母国語のようには英語、できるようにはならないと思うがなー、僕は。
小学校から英単語覚え始めたってその分、多くなんて覚えられないと思うんですけど。
 
Main article: Monitor hypothesis
 
For instance, one component of the Monitor Model,
propounded by Krashen, posits a distinction between “acquisition” and “learning.”
 According to Krashen, L2 acquisition is a
 subconscious process of incidentally “picking up” a language, as children do when becoming proficient in their first languages.

Language learning, on the other hand, is studying, consciously and intentionally, the features of a language, as is common in traditional
classrooms. Krashen sees these two processes as fundamentally different, with little or no interface between them. In common with
connectionism, Krashen sees input as essential to language acquisition.
中学校の英語の勉強を前倒しで始めてその分、学校の英語の点数が良くなるということは十分あるとは思いますけどね。
みなさんはどう思います?
