where is my pen?i()it well.这个题目为什么不能选must have kept呢?
用来表示我的笔在哪里,我刚才肯定是放好了的.这样表达不行吗?为什么一定要选择should have kept呢?

should have kept是虚拟语气.
语法是：should have +done 表示“本应该.”,对已发生的动作的一种虚拟
再问：那为什么不能选 must have kept呢？
再答：根据前一句 where is my pen?（我的笔在哪儿）可以看出说话人是找不着自己的笔了，因此后悔地说：我应该把它放好的
再问：那也可以是说话者肯定自己放好了笔，但认为笔莫名其妙的不见了也可以啊，这道题目太活了点吧
再答：意思上说得通，但语法和英语表达习惯上不会这么搭配。毕竟语言不是汉语，要遵循西方的逻辑思维习惯
再问：那么he ()you more help,even though he was very busy.might given;might have given.中为什么选第二个呢？might given不是也表示可以给于帮助的意思吗？这又不是对过去的假设，还是说是对过去的推测，所以用might have given吗？
