Grammar highlights
核心概念：main clause & dependent clause
main clause 主句：可以独立成为完整句子（有完整主谓）
dependent clause 从句：不能单独成句，必须依靠主句；由连词 when /because 引出。
句子基本语序（教材优先用：主句 + 连词 + 从句，不加逗号）。
① 主句 + when + 时间从句：I feel free like a bird｜when｜I’m cycling.
② 主句 + because + 原因从句：She tries to get eight hours of sleep every night｜because｜she believes getting enough sleep keeps her active during the day.
