语言视角
用母语深入讲解
Requests, commands, and prohibitions use 请, imperative context, 吧 for softening, and 别/不要 for negative commands.
请坐。
qǐng zuò = please sit
在所学语言中
英语的请求和命令可以用祈使句、情态动词、please、疑问句形式以及语调来调节直接程度，例如 Close the window、Please close the window、Could you close the window? 语气不同。
Please close the window.
Please + close：please 加动词原形 close，表示礼貌的请求或命令。
学习者可能照字面使用命令句，听起来太直接；也可能不知道用 please、could you 等方式让语气更礼貌。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
