Question

【题目】“How did the ancient people build that stone bridge?” asks Tom. （改为间接引语）

Tom wants to know _________ the ancient people _________ that stone bridge.

Answer 1

【答案】how built

【解析】

句意：汤姆问：“古代人是怎样建那座石桥的？”

直接引语变成间接引语，know后面的宾语从句的引导词是疑问词how;根据“How did the ancient people build”可知问的句子是一般过去时态，在从句中用陈述句语序，主语the ancient people后面用谓语动词的过去式built。故答案为how和built。
