在宾语从句中，宾语部分怎样区分陈述句，疑问句，和特殊疑问句？另外she doesn‘ t know————

Question

a.how long was Nancy back b.how long Nancy was back c.how long has Nancy been back d.how long Nancy has been back 选几？这时疑问句？or？
理由！！加分！！5~20
题错了！！是Do you know————最后有个For two days

Answer 1

题没有错， 选D项，宾语从句中的从句若为特殊疑问句，那么从句用陈述句语序即：特殊疑问词+主语+谓语；
另外此句考察现在完成时的第二种用法：从过去的某一时间起持续至现在的动作（必为可持续动词）用现在完成时表达。
1. Our teachers always give us good advice. We should follow _________.（2012冀中考45题）
A. what they say B. what they said C. which they say D. which they said
正确选项为A
2.Jenny is on holiday now. I wonder ________. （2011冀中考45题）
A. when she will come back B. when she came back
C. when will she come back D. when did she came back
正确答案也是A
不再多举例，希望我的解答对你有所帮助，你能够顺利地弄清晰这个重要的知识点

Answer 2

选D
Do you know---？是问句（这是主句）
how long Nancy has been back 是know的宾语从句
所以的宾语从句都是用陈述句，而不是问句
特殊疑问句=特殊疑问词+一般疑问句 如A和C项
当宾语从句时wh- 时
结构是：wh- +主语+谓语+其他追问

谢谢了，因为实在不好选，就随便选了一个。。。
