选择题
---That actor often joins in different activities in Beijing. Do you know ____?
---For 5 years.
A．how soon he will come back
B．how long he has stayed there
C．when he went there
D．when he will come here
答案
答案：B
题目分析：英语宾语从句中一般为陈述语序。根据下文，已经五年了。可知上文问的是时间长短，选项A为倒装语序，故选B。
点评：宾语从句中一般为陈述语序，需注意当疑问词做从句主语时，则貌似倒装句，需注意区分。关于引导词的区分需结合引导词的基本含义及其在句子中所承担的句子成分进行具体分析。宾语从句的时态和主句没有必然的联系，需结合语境具体分析。
