求翻译：64课是本单元最后一课。所以我认为在一个阶段的英语学习之后来一个总结是很必要的。首先我想设计一些活动让学生来复习“问路和指路”的表达方法。在听、说、读、画之后，我想给他一个链式训练作为巩固。是什么意思？

64 is the final lesson of this module. So I think after a stage of English learning to a summary is needed. First of all, I want to design activities for the students to review "asking the way and the way" method of expression. After listening, speaking, reading, painting, I want to give him a chain training as consolidated.
