Understanding and expression are inseparable as brothers. Only by brewing in advance can we express it more appropriately in our own words. If the understanding is not in place, it will only make the expression unsatisfactory and make the listener confused. In view of the fact that the landlord wants to exercise for primary school students, he should collect some illustrated books, such as fables, fairy tales, ancient prose and novels. Let primary school students read a book 10 minutes, and then perform for the students who haven't read it with their own words and body movements. You can also watch the same story and act it out in turn to see who really plays it well. In this way, in the long run, it can deepen the understanding and expression ability of primary school students and stimulate them.
