The lesson focuses on practicing the Chinese sentence structure “because… therefore” and the expression for “you’d better.” Students follow along in the textbook “Easy Steps to Chinese 3,” working through sentences that use these structures, such as “因为弟弟今天生病, 所以他没有去上学” (“Because my younger brother is sick today, therefore he did not go to school”). Additionally, learners are reminded of the Chinese expression for “heavy rain” (下大雨) to construct sentences like “因为今天下大雨, 所以我不能外出” (“Because it is raining heavily today, therefore I cannot go out”).
