The role of holiday homework: people's memory has a certain period. In fact, it forgets its previous knowledge every day. Holiday homework is to help you consolidate your existing knowledge so that you won't forget it so quickly, and to strengthen the memory function of your brain for knowledge, so that you won't forget it after accumulating day by day. In fact, everyone is looking forward to the holiday, and how many can resist the temptation to play? Hard-working students will not finish all day like wood. They arrange their time reasonably, play when they should, and do their homework when they should. In fact, they don't have to spend too much time doing their homework a day, just a few hours. Only in this way can the homework be completed efficiently and played well. Why not?
