The students of Class 3 had a discussion about if it is necessary learn English from childhood. Some think it necessary. As a little boys and girls have a very good memory, they can learn many English words by hearts, which will help them lay a solid foundation for their future English learning. But others do not agree. Children have to learn Chinese Pinyin. If they study Chinese Pinyin or English at the same time, it will be very easily for them to mix them up. This would do a lot of harm with their learning. In short, the students have not reached any agreement still.
