宾语从句歌诀宾语从句三姊妹,that,if/whether,wh-/how 展风采
展风采有三关,引导词、语序、时态在把关
主从时态要一致,陈述语序永不变
陈述请你选 that,疑问需用 if/whether 连
特别问句作宾从,原来问词不用换
三关过后莫得意,人称、标点需注意
留意变脸的 if/when,从句的简化记心间
一、三姊妹 宾语从句根据引导词的不同可分为三种类型: 1
由 that 引导的宾语从句
如: We knew (that)we should learn from each other
由 if/whether 引导的宾语从句
如: Please tell me if/whether you have been to America
由 who,where,how 等连接代词或连接副词引导的宾语从句
如: Can you tell me how I can get to the nearest post office
二、三关 1
引导词关 假如从句是陈述句,引导词用 that(that 在口语或非正式文体中常省略);假如从句是一般疑问句,引导词用 if/whether;假如从句是特别疑问句,引导词用由疑问词转换而来的疑问代词/副词
语序关 ①陈述句变为宾语从句,语序不变,即仍用陈述语序
如: He is an honest boy
The teacher said
→The teacher said (that)he was an honest boy
②一般疑问句和特别疑问句变为宾语从句,语序变为陈述语序
如: Does he work hard
I wonder
→I wonder if/whether he works hard
When did he leave
I don’t know
→I don’
