一.组织课堂教学
二、课内探究
(一)明确目标
师生共同了解本节课的知识目标,重难点。使学生明确本节课的学习任务,保证学生有能力做到。
(二)师生共同 复习
让学生尽量总结引导宾语从句的各种引导词、宾语从句的语序、主句与从句在时态上的呼应。
(四)考点梳理:
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3种情况只能用whether:
a.在不定式前:Whether to go there or not hasn't been decided.
b.在介词前:It depends on(依靠) whether it is going to rain.
c.与or not连用:They are talking about whether to go there or not.
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。
【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 how I should do with the presents. ==> I don't know how to do with the presents.
2.要注意区分判断由if、when引导的从句类型.
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。
Can you tell me who do we have to see?(╳)
Can you tell me who we have to see?( √)
The teacher asked the students what they were doing.
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。
