Research clearly shows that young children are able to become fluent in more than one language at the same time，if there is rich input in each language. In this context，it is 1．(good) to start as young as possible.

Learning in language classes at school is 2． (complete) different. The normal pattern of these classes is to have one or more hourly 3． (lesson) per week. To succeed in learning with such little input 4．(require) meta-cognitive(元认知) skills that do not usually develop 5． a young age. For this style of language learning, the later years of primary school is 6． ideal time to start.

What does this tell us about when we should start teaching second languages to children? In terms of the 7． (develop) of language proficiency，the message is fairly clear.

If we are able to provide lots of exposure to rich language use, early childhood is better. 8． the only opportunity for second language learning is through more traditional language classes, then late primary school is likely to be just as good as early childhood.

However, if language learning relies on 9． (be) self-directed, it is more likely to be 10． (success) after the learner has reached adulthood.
