C-----your food well before you swallow it.

问题描述:

C-----your food well before you swallow it.
before前面那块是主语吗?

NHK : Chew your food well before you swallow it = 充分咀嚼你的食物, 当你吞下它以前...整句来说...其实应该是 (You should +) chew your food well before you swallow it = (你应该 +)充分咀嚼你的食物, 当你吞下它以前...所以...被隐藏的 You should...当中的 You...就是"你"...才是这句的主角...你用中文...也不会说..."他 / 她"应该充分咀嚼"你"的食物, 当"你"吞下它以前...嘿嘿嘿...所以整句的主角...都是你.
