改错并指出错误I wanted to know whether have they been to the Great Wall
I wanted to know whether they had been to the Great Wall
我这样改的原因是：
1、关于have been顺序的调整
这是因为在whether 后用陈述语序,而不用疑问语气.
更多例子：I don't know whether he can do it.我不确定他是否能完成
2、关于have 变成had
由于主句是wanted,已经表示了过去的时态,而又在讨论他们在我wanted to know这一过去动作之前,是否去过长城,过去的过去用过去完成时.
应改为I wanted to know whether they have been to the Great Wall.
whether引导know的宾语从句，因此应该为陈述句语序。
谢谢！
I wanted to know whether they have been to the Great Wall
宾语从句用陈述句语序
I wanted to know whether they had been to the GreatWall
宾语从句用陈述语气
主句用过去时态，从句还问“以前”，为以前的以前，用过去完成时
二三楼错
I wanted to know whether have they been to the Great Wall
我想知道他们是否去过长城。
I wanted to know whether they have been to the Great Wall or not.
或者
I wanted to know if they have been to the Great Wall.
I want to know whether they have been to the Great Wall.
I wanted to know whether they had been to the Great Wall.
注意：
1.句子前后时态要一致！
want对应have been,wanted对应have been.
2.whether引导的从...
全部展开
I want to know whether they have been to the Great Wall.
I wanted to know whether they had been to the Great Wall.
注意：
1.句子前后时态要一致！
want对应have been,wanted对应have been.
2.whether引导的从句是want to know的宾语从句，所以用一般陈述语态，即主语在前，谓宾在后！
