② help sb. (to) do sth.：help后接动词原形或to do，不接动名词
③ 祈使句：动词原形开头（Pass me.../Help yourself.）；否定用Don't...（Don't waste...）
④ Can/Could you + 动词原形？用于礼貌请求（Could比Can更礼貌）
⑤ pass sb. sth. = pass sth. to sb. 双宾语结构可互相转换
⑥ 情态动词can/can't + 动词原形，表能力，无人称变化
⑦ 名词复数：chopstick→chopsticks, dish→dishes, glass→glasses, knife→knives
⑧ 礼貌用语：Would you like...? / Of course. / Sure. / Thank you. / You're welcome.
⑨ 否定祈使句：Don't + 动词原形（Don't waste food. / Don't litter.）
⑩ 综合：餐桌礼仪场景——帮助他人、礼貌请求、自我服务、收拾清理
【考点一：反身代词 myself / yourself / himself / herself / themselves】
📌 反身代词表示"某人自己"，作宾语或同位语。第一二人称由"物主代词+-self/selves"构成，第三人称由"宾格+-self/selves"构成。
