2. 宾语从句的概念和结构(10 分钟)
讲解宾语从句的概念,即在句子中起宾语作用的从句。并通过示例展示宾语从句的基本结构:连接词+主语+谓语+其它成分。
3. 连接词的使用(10 分钟)
介绍宾语从句中常用的连接词,如 that, if, whether,what等,并讲解它们的用法和区别。
在宾语从句中,连接词(Conjunction)起到连接主句和从句的作用,常见的连接词包括 that、if/whether、疑问词等。以下是这些连接词的用法:
① that:that 在宾语从句中不充当任何成分,没有实际意义,通常可以省略。
● He said (that) he would come back soon.
② if/whether:if 和 whether 通常用于引导一般疑问句转化而来的宾语从句,表示“是否”。
● I don't know if/whether he will come.
注意:在下列情况下,只能用 whether,不能用 if:
- 当从句中有 or not 时:I don't know whether he will come or not.
- 当从句作介词的宾语时:We are talking about whether we will go on a trip.
- 当从句放在句首时:Whether he will come, I'm not sure.
③ 疑问词:疑问词包括 who、whom、what、which、when、where、why、how 等,它们在宾语从句中充当一定的成分,如主语、宾语、表语、状语等。
● He asked me what I was doing.
注意:当疑问词在句中作主语时,语序不变。
● I don't know who will come.

4. 时态(10 分钟)
在宾语从句中,动词的时态需要根据主句的时态进行变化,具体规则如下:
● 主现从任:主句动词为现在时,从句动词时态任意,不受限制。
● I know that he is a teacher. (我知道他是个老师。)
● I know that he was a teacher. (我知道他过去是个老师。)
● I know that he will be a teacher. (我知道他将要成为一个老师。)
● 主过从过:主句动词为过去时,从句动词必须为过去时的某一种形式。
● 若从句动词发生在主句动词之前,应选择过去完成时或过去完成进行时,表达"过去的过去"。
● She said that she had seen the film before.
● I asked where they had been staying all those days.
● 若从句动词发生在主句动词之后,应选择"过去将来时"的某一种形式,表达过去的将来。
● He told me he would go to Beijing.
● 若强调从句动词在主句动词发生时刻正在进行,应选择过去进行时。
● They said that it was raining.
● 若不强调两动词发生的时间顺序,则选择一般过去时。
● I didn't know you were in Paris.
● I thought you were ill.
