句子的骨干是个宾语从句.
主语：Hans
谓语：explained
宾语（从句）：how it was that he was still alive.
其中宾语从句又是一个强调句,还原回普通句为：how he was still alive,意思是,“他是怎样活下来的.”看不懂这句强调句，强调句不是it is ..that 吗从句改强调句怎么改？请指教特殊疑问句改为强调句：疑问词如why+is/was it +that +其它，如果这个特殊疑问句要做宾语从句，那么只需把is/was和 it的位置调就行了，就像陈述语序一样。 【俊狼猎英】团队为您解答。请尽快采纳。特殊疑问句改为强调句：疑问词如why+is/was it +that +其它，如果这个特殊疑问句要做宾语从句，那么只需把is/was和 it的位置调就行了，就像陈述语序一样你是说，这个特殊疑问句不改为强调句作宾语从句时（即单纯的特殊疑问句做宾语从句），只需把is/was和 it的位置调就行了，吗？单纯的特殊疑问句做宾语从句，根本没有it is/was...that结构，又何来把is/was和 it的位置对调呢？只需按照下面的语序：特殊疑问词（或者连同被它修饰的成分）+主语+谓语就行了。如：Hans explained how he was still alive. 【俊狼猎英】团队为您解答。how was he still alive-----how was it that he was still alive特殊疑问句----特殊疑问句的强调句how was it that he was still alive的特殊疑问句的形式是这样的吗how was he still alive完全正确！本题解答到此为止，请即采纳！ 【俊狼猎英】团队为您解答。请尽快采纳。how was he still alive-----how was it that he was still alive特殊疑问句----特殊疑问句的强调句为什么不是how was it that was he still alive?本题不再解答。如再有疑问，请另外提问。 【俊狼猎英】团队为您解答。问题是我还没完全懂，为什么不教懂我吧，帮人帮到底。 how was he still alive-----how was it that he was still alive特殊疑问句----特殊疑问句的强调句为什么不是how was it that was he still alive? 特殊疑问句：how are your roommate's request and yours identical ? 表强调的的特殊疑问句：how is it that your roommate's request and yours are identical? 这句是这样的吗先采纳吧！
