题目

陈述句改疑问句
The Russians and Germans have built a new Amber Room at the summer palace.By studying old photos of the former Amber Room.
改成两个疑问句
1.Who built the new Amber Room?
2.What did they built the new Amber Room by?
帮我看看有没有语法错误或者意思不对的地方?
有倒是说啊！别捣乱

答案

你原句是现在完成时态,建议第一个问句也用完成时态.
第二个问句是提问"通过什么方式的",不用what by,直接用"how"
修改为:
1.Who have built the new Amber Room?
2.How did they build the new Amber Room by?
