英语中,在复合句中作宾语的句子叫作宾语从句。请注意以下问题:
1. 宾语从句由连接代词或连接副词来引导
(1)that引导宾语从句时,在句子中不充当任何成分,在口语和非正式文体中常被________。例如:
They said they had been there before.
他们说他们以前去过那儿。

I don't know if/whether they will come here.

I can't decide whether to stay.
我不能决定是否留下。
(3)如果宾语从句是____________,则由特殊疑问词what, how, which, when, where, why等引导。例如:

Ⅰ. 单项填空
( )1.2017·安徽—Do you know ______ Ann goes to work every day?
—Usually by underground.
A.why B.how
C.when D.whether
( )2.2017·泰安—The light in Bill‘s office is still on. I wonder_____.
—Maybe at midnight again.
A. if will he stop workingB. why he works so hard
C. how long will he workD. when he will stop working
【解析】考查宾语从句。宾语从句需用陈述语序,由此排除A、C项;由下一句“可能又要到午夜”可知,上一句是询问时间,应用when引导宾语从句。故选D。
( )3.2017·乐山改编—Do you know ________ next Friday, Lily?
—If it doesn't rain, we will.
A. if we will take a field trip
B. will we take a field trip
C. why we will take a field trip
D. why will we take a field trip
【解析】考查宾语从句的用法。宾语从句要用陈述语序,排除B、D项;再由句意可知,C项中的连接词why与句意不符。故选A。
