1，must have been 虚拟语气，表推测，意思是一定
2，had to 因为没有推测的意味，表是原因，意思是不得不
3，must have been 可以翻译过来试试就知道了。因为不可能有“不得不是某国人”这样的句子的。所以只能是推测某人可能是某国人。
4，had to 前面说出了原因，后面就“不得不”这样做了。“他把方案忘在家了，所以他不得不回云取。”这里也没必要推测，因为“他”不得不这样做。
5，must have been这是对为什么没听见电话的一种推测，她不可能“不得不”在睡觉。
总之：虚拟语气表示推测，而且很强烈，而had to表示非此不可，不必推测。

1.must have been
2.must have been
3.must have been
4.had to
5.had to
6.must have been
must have been 是表示根据现在的实际情况而进行的主观的一种推测！
had to 是表示对于现实的一种无奈的接受！有点不乐意，又没有办法的含义！
