My mp4player isn't in my bag where ()i have put it?
My mp4 player isn't in my bag . Where can I have put it? 赞同黎老师的解答。can表示推测不能用于肯定句，但可以用于疑问句和否定句。情态动词表示对过去情况推测时，要后接不定式完成体have done形式。所以 Where can I have put it?是正确的形式。正因为说话人想不起来自己把播放器放哪里了，所以不会用推测时信心程度...

关于现在完成时的问题
这个句子的翻译是错误的。作为不及物动词，increase为终结性动词，英英释义为：[no object] : to become larger or greater in size, amount, number, etc. 终结性动词的非进行体表示单个事件，为发生并结束的事件，导致主语状态的改变。本句的has increased为事件完成体，表示速度的增加发生在不确切的过去时间，强调结果—...

关于虚拟语气
were broke显然是输入错误。应为 were broken. 不能用过去式broke, 因为从句表示的是一种状态，而不是一个瞬间动作。were broken是系表结构，不是被动语态。

如何理解 should+主语+be 这样一种“陈述语序”的结构？
选择问句的选择部分可能是完整的句子。例如，我现在需要某个东西，是我去超市买呢，还是汤姆从家里带一个？这样的选择问句就不省略成分：Should I buy it in the supermarket or would Tom bring one with him from home?当我们把这个选择问句用作名词性从句时，我们用whether引导这个选择问句，同时问句改用正常语序，去掉...

融合性关系词
融合型关系词包括融合型关系代词、融合型关系限定词和融合型关系副词。之所以称这类词为融合型关系词，是因为这类词是把先行词和引导定语从句的关系词合二为一了，即先行词与关系词融为一体。例如：融合型关系代词what= the thing which。 其中the thing为先行词，which为关系代词。This is what he gave to me. = This is...

为什么要说成could have disarranged ? 为什么不是could disarra...
which could have disarranged my plans. 可能把我的计划给打乱了。我现在可能需要改变计划了。说话人根据当前的情况（大雾正向自己的方向移动），推测某件事在过去可能发生了（大雾的出现可能把他的计划打乱了）。所以用could have done.
