Young although the boy is he knows a lot.这个病句怎么改?

young改成though 或asa。/n。as/though sb be是倒装的固定形式,考试中常见。原句的正常语序是就是as/though the boy is young尽管这个男孩还小例如Young as/though the boy is,he knows a lot。尽管这个男孩还小,但他知道很多。Child as/though he is,he knows a lot。尽管他只是个孩子,但他知道很多。Old as/though he is,he is still vigorus。虽然他很老,但是很有活力。 再问： 我纠正一下，although改成though 或as 还是很感谢，明白了。
