If与Whether的区别
Lead-inFree talkD yu like teacher?I like my teacher.(名词作宾语)What d yu like sprt?I like playing basketball.(动名词作宾语)宾语是动作、行为的对象,是动作的承受者。宾语由名词、代词、不定式或相当于名词的词、短语来担任。
I like my teacher.(名词作宾语)I like playing basketball.(动名词作宾语)I decide t study hard.(不定式作宾语)I knw him .(代词作宾语)宾语是动作、行为的对象,是动作的承受者。宾语由名词、代词、不定式或相当于名词的词、短语来担任。
We knw him.
We knw he likes English.
一 什么 是宾语从句?
概念:句子的宾语一般由名词、代词、 动名词或动词不定式充当,当一 个句子充当宾语时,我们把这个句 子叫做宾语从句。 宾语从句当中的从句在全句中作宾语
We knw he likes English.主S 谓V 宾O
Find ut the Object Clauses
We are prud f that Beijing is ne f the biggest cities in the wrld .D yu knw where he cmes frm? He asked me if I culd get t the bus statin n time.
引导词可以简单的分3类:宾从陈述句,that来引导;宾从特问句,特殊疑问词引导;宾从一般问句,if、whether来引导。
2.由连接代词 Wh,whm,whse,which,what和连接副词 where,hw,why,when引导的宾语从句。这些连词既有词义又充当句子成份。
e.g.1)D yu knw whse bk it is ?(谁的,作定语) 2)Culd yu tell me why the train is late? (为什么,作状语) 3)He asked wh culd answer the questin.(谁,作主语)
注:that 在句中无词义,在从句中不能充当句子成分,在口语中往往被省略.连接的宾语从句是陈述句。
e.g. I hear (that) he will be back in an hur.
1.由从属连词that引导的宾语从句
二 .宾语从句的引导词
3.由从属连词 whether, if 引导的宾语从句
e.g. I want t knw if/whether she is right . They didn’t knw whether Tm culd cme back r nt .
if/whether 引导宾语从句 表示“是否”之义,在句中不充当句子成份。 if/whether可互换,但whether…r nt为固定搭配.
看一看:I dn’t knw if it will rain tmrrw.If it rains ,I’ll stay at hme. I want t knw when he will cme back.When he cmes back, please tell me.想一想:when和if 可以引导什么从句?它们的时态有什么特点?
when和if 既可以引导宾语从句,也可以引导状语从句。在宾语从句中,时态根据需要确定;在状语从句中,遵循主将从现的原则。
If 与whether 的区别
I dn’t knw _____ he will cme r nt.I dn’t care f ______ he is handsme.He wndered ______ t stay here the next week.____ he will cme is nt decided.
与r nt 连用只能用whether
介词后只能用whether
与t d 不定式连用只能用whether
作主语只能用whether
Helen says that she will learn French next year. D yu knw where he cmes frm? He asked me if I culd get t the bus statin n time.
无论主句是陈述句还是疑问句,宾语从句都是运用陈述句的语序,即是“主语在前,谓语在后”的顺序。
将下列问句变成陈述句。
1. Can he swim ? → swim .
2. Des he have a pen ? → a pen .
3. Which place did he g t ? →Which place .
4. What's wrng with yu ? → .
5. What happened t yu ? → .
6. Which is the way t the statin? → . 想一想 为什么4,5,6 语序不变?
What happened t yu
What's wrng with yu
说一说将上面的句子置于一个主句后,变成一个宾语从句。
Which is the way t the st想一想 为什么4,5,6 语序不变? atin
Can yu tell me/I want t knw/I wnder/Please tell me……?e.g. Can yu tell me if/whether he can swim?
2.当主句是一般过去时的时候,宾语从句必须运用相应的过去的某一种时态,从而达到主句和从句的相互一致。(呼应性原则)
1) He will g t Hng Kng .2) He is sick.3) He is reading a bk . 4) He has finished his wrk.
1) he t Hng Kng .
2) he sick.3) he a bk . 4) he
was reading
had finished
四.宾语从句中时态的变化
was playing
had learned
1.当主句是一般现在时,宾语从句的时态不作限制,我们可以根据句子的需要使用任何一种时态。(需要性原则)
确定从句的时态(根据主句时态)
从 句 时 态
3.当宾语从句说明的是客观存在的事实或者是客观存在的真理时,就不用受到主句时态的限制,仍是用一般现在时态。(特殊性原则)
He tld me (that)
Summer is after Spring .
I was tld (that)
the sun is much bigger than the mn.
My parents tld me (that)
n news is gd news.
比一比 I dn’t knw where I shuld g. Tell me hw I can d it. I dn’t knw where t g. Tell me hw t d it. 你有什么发现? 结论:由连接代词和连接副词引导的宾语从句 ←→疑问词 + t d 的简单句。
条件:(1). 主主从主 (2). 主(间)宾从主练一练
1.I dn’t knw what I shall d next .(变为简单句)
→ I dn’t knw next .
2.Jhn didn’t decide which bk he wuld buy .(变为简单句) → Jhn didn’t decide .
五.宾语从句与简单句的转换
What t d
which bk t buy

if/whether(一般疑问句 )
特殊疑问词(特殊疑问句)
主句为一般现在时从句可为任何时态
宾语从句的语序都为陈述句语序
客观真理 自然现象公式定理 名言警句 时态不变
