The child's slow reaction may be caused by insufficient communication with others. Many parents are usually too busy to communicate with their children, so children can only face electronic products such as mobile phones and computers for a long time to relieve boredom. These ways, such as watching cartoons, belong to one-way output. Children can't communicate with mobile phones on computers. After a long time, children will feel particularly strange about spoken English. When listening to others, they often have to react before they know what it means. This requires parents to communicate more with their children and actively improve this situation. Every child has individual differences. Some children are quick-witted, while others are slow-witted. There is no need to be too demanding. If the child is particularly slow-witted, parents can improve the child's reaction ability through scientific training methods. Parents ask their children to help them solve their difficulties. For example, if they can't recite a long article, they will break it down into their acceptable length. Let them recite it in small pieces and make a plan every day, so that they can help their children complete the task. Or parents can improve their children's attention, memory and reaction ability by talking about games, asking questions frequently and making demands on their children.
