宾语从句教案设计

(The Object Clause) 教学目标：

1.掌握引导宾语从句的各种连词

2.掌握宾语从句的语序──主句+连接词+主语+谓语

3.掌握宾语从句，主句与从句在时态上的呼应。

教学重点难点

重点：语序和时态呼应

难点：语序和时态呼应;与疑问词+不定式的转化;与状语从句的辨析

教学过程

一、宾语从句的连接词

1.连词that，只起连接作用，在从句中不作句子成分，也无词汇意义，在口语中常被省略。

eg. He knew (that) he should work hard. 2.连词if 、whether，它们起连接作用，在从句中不作句子成分，作“是否”解，在口语中多用if。

eg. Tom don't know if/whether his grandpa liked the present. He asked me whether or not I was coming. 一般情况下，if 和whether可以互换，但以下4种情况只能用whether：

①介词之后 ②与or not连用 ③

置于句首 ④

不定式前

①They are talking about whether she will go there. ② They wondered whether she would go there or not.

③

Whether they will walk to the zoo I don’t care.

④ I want to know whether to walk there. 3.连接代词who, whom, whose, what, which，连接副词when, where, why, how，

它们起连接作用，作句子成分，各有自己的意义。

eg. The teacher asked the new students which class he was in. I wonder where he got so much money. 【注意】

1.由连接代、副词引导的宾语从句可以和“疑问词+不定式”结构转化。

eg. I don’t know which one I should choose. ==> I don’t know which one to choose. I don't know what I should do with the presents. ==> I don't know what to do with the presents. 2.要注意区分判断由if、when引导的从句类型. 我不知道明天是否会下雨，如果明天下雨，我要呆在家里看电视。

I don’t know if it will rain tomorrow. If it rains tomorrow, I will stay at home and watch TV. 在条件状语从句中使用if,意思是如果，用一般现在时表示将来。在宾语从句中使用if,意思是是否，从句的谓语动词的时态应根

据主句的时态作相应的变化。 我不知道何时会下雨，当下雨时，我要长大。

I have no idea when it will rain. When it rains, I will grow up. 在条件状语从句中使用when,意思是当……的时候，用一般现在时表示将来。在宾语从句中使用when,意思是何时，从句的谓语动词的时态应根据主句的时态作相应的变化。

二、宾语从句的语序

宾语从句的语序是陈述语序，即“连接词+主语+谓语+其它成分”。特别强调：它的主语和谓语的语序是陈述语序，而不是疑问句的倒装结构。

Could you tell me how do you go to school?(╳) Can you tell me who(m) we have to see?( √) The teacher asked the students what they were doing. (what在从句中的成分) 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。

eg. She said, “I will leave a message on the desk.”

→ She said she would leave a message on the desk. 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,后面接陈述语序。Eg. “Where are the tickets?” I asked him. → I asked him where the tickets are. 三、宾语从句的时态呼应

宾语从句中谓语动词的时态，常常受到主句谓语时态的制约，此为时态呼应。如果主句谓语是一般现在时或将来时，从句谓语的时态不受限制;如果主句谓语的时态是一般过去时，从句一般要随着改为相应的过去时态(一般过去时、过去进行时、过去将来时、过去完成时)。

eg. I thought (that) you are free today. (╳) I thought (that) you would be free today. ( √) 【注意】当宾语从句叙述的是客观真理时，不管主句谓语的时态如何，从句都用一般现在时。

eg. The teacher told us (that) the earth moves around the sun. 四. 标点由主句决定。

如主句是陈述句、祈使句，则用句号;是疑问句则用问号。

1.

I heard she had been to the Great Wall. 2.

Can you tell me which bus I should take? 3.

Excuse me, could you tell me if you are interested in English?
