教学过程
Step 1. Lead-in. 宾语的概念。 什么是宾语？宾语是动作、行为的对象，是动作的承受者，它可以是名词、代词、不定式或者相当于名词的词或短语来担任。 eg： I love my family.名词作宾语。 I understand you.代词作宾语。 She likes dancing.动名词作宾语 I want to buy a dictionary.动词不定式作宾语。 Step 2. 宾语从句的概念 在复合句中，由句子充当宾语，位于及物动词、介词或复合谓语之后的从句叫作宾语从句。I think that mooncakes are delicious! 宾语从句的构成：主句+引导词+从句。 Step 3. 宾语从句的引导词 如果从句是陈述句，引导词用that.，that 无词义，在口语或非正式文体中常省略。 eg: I think (that) he will return in two hours. The teacher said (that) I was right. I am sure (that) he will succeed. 如果从句是一般疑问句，可以用if/whether来引导，意思是“是否”，在口语或间接引语中两者可以互换。 eg: I wonder if/whether he is a good learner. Alice wants to know if/whether she has passed the exam. 注意: 当从句后有or或者or not时，只能用whether. eg: I don't know whether or not they will come. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。 eg: Do you know who (whom) they are waiting for Can you tell me where the bus stop is I don't know why he is late again. 注：连接词就是疑问词本身。 Step 4. 宾语从句的语序 宾语从句的主句和从句都可以是陈述句也可以是疑问句，但从句都必须使用陈述语序。陈述语序就是“主语在前,动词在后” 陈述句语序表达方式： 1.主语+动词 2.主语+助动词/情态动词+实义动词 eg: Can you tell me where the restroom is Do you know when the meeting will begin Step 5.宾语从句的时态 如果主句是一般现在时，从句可以用任何时态。 eg: I'm sorry to hear that you were ill last week. He thinks that they will give him a visa tomorrow. 主句用一般过去时，从句用与过去相关的时态。 eg: She didn't know that Tom had left for Shanghai . She said that she would come to the meeting. 从句说明的是一般真理、客观事实、自然现象、名言时,无论主句是什么时态，从句都要用一般现在时。 eg: The teacher told us that light travels faster than sound. Step 6.
