: 哈囉~
: 最近聽廣播聽到 that's all we have time for today...
: 我知道意思 但是覺得文法好像怪怪的....
: 也有聽過 that's all the time we have for today.
: 查過google 兩種都有人說
: 但是第一句的文法到底對不對阿= =
: that's all 後面為什麼有另一個子句...
: 有人可以幫我解惑嗎?
: 謝謝

第一句還是怪怪的 that不能當後面子句的主詞或受詞

vic，看看這句：That's all (that) I ate this morning.that確定是可以當受詞，只是前句是介詞for的受詞，我剛剛那句是動詞ate的受詞。

懂了 是 we have time for -- today 斷句的位置 (拜)

感謝 我有另一個想法就是that's all (that) we have time for todaywe have time 這裡當名詞子句 補述說明all這名詞這樣看好像也通
