Step Ⅰ Warming-up
Look at the pictures and sentences, and then say object clauses according to the given information.设计意图：让学生在真实的情境中回顾if/whether及疑问词引导的宾语从句，为本课时的语法学习奠定基础。

Step Ⅰ Presentation
Language practice
Read the sentences in the box and pay attention to the colored words.
Grammar
T explains the use of the object clause with whether/if and wh-words.
宾语从句三要素：连接词、语序、时态
宾语从句的连接词
1. 连词that，起连接作用，在从句中不作句子成分，也无词汇意义，在口语中常被省略。

2. 连词if/whether，起连接作用，在从句中不充当任何句子成分，意为“是否”，不能省略，在口语中多用if。

注意：一般情况下，if 和whether可以互换，但以下3 种情况只能用whether：
(1) 在不定式前
(2) 在介词后
(3) 与or not连用
3. 疑问词在句中既起连接作用，作句子成分，又有实际意义：
连接代词：who, whom, whose, what, which
连接副词：when, where, why, how
who 在从句中作主语、表语；
whom 在从句中作宾语；
whose 在从句中作定语；
what和which 在从句中作主语、宾语、表语或定语；
when, where, why, how 在从句中分别作时间状语、地点状语、原因状语和方式状语。

宾语从句的语序
宾语从句的语序是陈述句语序，即：连接词+ 主语+ 谓语+ 其他成分。

☞Can you tell me where will we go?
☞Can you tell me where we will go?
☞I don’t know what they are looking for.
☞Can you imagine what kind of man he is?
☞Could you tell me when the train will leave?
人称和时态变化
1. 陈述句变为宾语从句时，要注意人称和时态的变化，语序不变。

2. 一般疑问句和特殊疑问句变为宾语从句时，也要注意人称和时态的变化，后接陈述语序。

设计意图：以本单元的句子为引子，总结whether / if及疑问词引导的宾语从句的用法。
