That's all we hvae time for today.
= That's all (that) we have time for today.
= Today, that's all (that) we have time for.
意思是：我们今天有时间聊（或做）的就是这些。
That's all the time we have for today.
= That's all the time we have...for today.
意思是：我们今天能用来聊天（或做事）的时间就这么多了
意思大同小异，不过都说得过去。
※ 引述《denisck123 (丹尼斯)》之铭言：
: 哈囉~
: 最近听广播听到 that's all we have time for today...
: 我知道意思 但是觉得文法好像怪怪的....
: 也有听过 that's all the time we have for today.
: 查过google 两种都有人说
: 但是第一句的文法到底对不对阿= =
: that's all 后面为什么有另一个子句...
: 有人可以帮我解惑吗?
: 谢谢

第一句还是怪怪的 that不能当后面子句的主词或受词

vic，看看这句：That's all (that) I ate this morning.that确定是可以当受词，只是前句是介词for的受词，我刚刚那句是动词ate的受词。

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

感谢 我有另一个想法就是that's all (that) we have time for todaywe have time 这里当名词子句 补述说明all这名词这样看好像也通
