關於英文被動式 eaten to eat?

# so：[接續詞] 釋義1. ((so that 的省略that )) 釋義(1-2)((結果))那個結果，在那裡，因此
# 本句沒(想)使用「被動語態」。
## Be sure to put the meat in the oven at 5:00 so (that) “it will be ready to eat by 6:30”. 華文譯：一定要在5點將肉放入烤箱，這樣“它就可以在6:30之前食用”。←← "it …… 6:30"子句係英文五句型的第二型：S.+V.+S.C.(主詞補語)，“(不定詞) to eat by 6:30"是真正主詞， "it"是形式主詞。
#參考例：Be sure to account for spoilage so that you will not have an underrun. (為了防止物品數量不足，請計算傷痕的數量。)

will be ready=passive voice;
to be eaten=passive voice;
eat=to have a meal=What and when shall we eat tonight?=dinner-meat and 6:30.
