C. if he goes on a trip to Wu xi      D. when does he go on a trip to Wu xi

【小知识】宾语从句的语序

无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,即“主句+连词+宾语从句(主语+谓语+……)”句式。根据连接词在从句中所担任的不同成分,可分为以下四种:

1)连接词+谓语。连接词在从句中作主语。常见的连接词有: who,what,which等。如:
Could you tell me who knows the answer,please?你能告诉我谁知道答案吗?
The small children don't know what is in their stockings.这些小孩子不知道袜子里有什么东西?

2)连接词+名词+谓语。连接词在从句中作主语的定语。常见的连接词有:whose,what,which,how many,how much等。如:
He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
The teacher asked us how many people there were in the room.老师问我们房间里有多少人。

3)连接词+主语+谓语。连接词在从句中作宾语、状语或表语。常见的连接词有:who(m),what,which,how many,how much, when,why,how,where,if /whether(在句中不充当任何成分)等。如:
He hasn't decided if he'll go on a trip to Wuxi.他还没决定是否去无锡旅行。
Could you tell me what I should do with the money ?你能告诉我我如何处理这笔钱吗?

4)连接词+名词+主语+谓语。连接词在从句中作宾语或表语的定语。常见的连接词有:what,which,how many,how much,how等。如:
Do you know which class he is in ?你知道他在哪个班吗?
She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。
