At the age of three, the younger a child is exposed to a second foreign language, the easier it is to learn it well, just as we have been exposed to Chinese since childhood. Of course, this does not mean that we should deliberately enroll our children in an English remedial class. Teachers don't always speak Chinese to such a small child, and the effect is not very great. It is suggested to create more English atmosphere at home. If parents speak English best, they can communicate more with their children. If not, they should put more children's English songs and CDs on their walls for children to learn English.
