答案：
The students of No. 4 High School had a discussion about whether it is necessary to start learning English from childhood. Some of them think that English learning should start from childhood. As little boys and girls have a very good memory, they can learn a lot of English words by heart. This will help them lay a solid foundation for their future English learning. But others do not agree. Young children have to learn Chinese pinyin at school. If they study Chinese pinyin and English at the same time, it will be very easy for them to mix them up. This will do a lot of harm not only to their Chinese learning but also to their future English learning. In short, the students have not arrived at any agreement yet.
