【Object clauses】 二、由if / whether引导的宾语从句
当宾语从句具有疑问意义时，可用if或whether引导。它们在句子中的意思是是否, 不能省略。
Ⅰ. if和whether引导宾语从句时，作“是否”讲，一般情况下，二者没有区别，可以换用。但if常用于口语中，whether比较正式。
如：Millie asked if/whether he liked this sweater.
米莉问他是否喜欢这件羊毛衫.
Ⅱ. 由于if和whether连接的是一般疑问句，因此要注意把从句语序改为陈述句语序。
如：Does Mr Zhao live in Room 208 Could you tell me
→Could you tell me if/whether Mr Zhao lives in Room 208
Ⅲ. if和whether的区别
二者在下列几种情况下不能换用：
1. 宾语从句与or not直接连用时，应用whether，不能用if。
如：I don’t know whether or not he will come tomorrow.
我不知道他明天是否来。
2. 与动词不定式连用时，只能用whether。
如：She can’t decide whether to go to America.
她不能决定是否去美国。
3.在介词后通常用whether
It depends on whether I have enough time.

Grammar
（一）宾语从句
I学习语法--2.教师点拨
一、宾语从句的概念
在复合句中，由一个句子充当宾语，这个句子叫做宾语从句。引导宾语从句的常见关联词有that，if，whether，what，who，where，why和how等。
We know Mr Green teaches English.
She asked if these answers were right.
二、宾语从句三要素
引导词（连接词）：that，if，whether
语 序：陈述句语序
时 态:主现从需，主过从过，从真为现。

【Object clauses】 三、宾语从句的时态变化
宾语从句的时态一般受主句时态的影响。当主句是一般现在时或一般将来时，宾语从句可以根据具体情况用适当的时态；当主句是一般过去时，从句要用相应的过去时。
主句时态 从句时态
一般现在时、一般将来时、祈使句时 根据句意的需要用任意一种时态
一般过去时 与原句相对应的过去的时态
客观事实、真理、自然现象、名言警句、谚语等,一律用一般现在时
I know(that) Jack is a hard-working student.
I know (that) he will take the exam.
Linda didn’t say if her aunt was still with them.
Dad told me that the sun rises in the east.
Teresa told her son that leaves turn yellow in autumn.
宾语从句歌：
学习宾从三注意，时态语序和连词。时态主从要呼应：
主句若为现在时，从句时态随句意；主句若为过去时，从句时态变过去；
宾从若是表真理，时态不变无质疑。语序要用陈述序，切莫照搬疑问句。
That 连接陈述句，省与不省要注意。从句若表“是否”时，if / whether要慎记。
特殊问句作宾语，仍用原来疑问词。三个问题需牢记，切莫丢东忘了西。
1. I hear (that) _______________________.
2. He said (that) ______________________.
3. The teacher told us (that) _______________ ________________.
he will be back in an hour
he missed us very much
the earth moves
由that引导的宾语从句
注：that 在句中无词汇意义，在从句中不充当成分，在口语当中往往省略。
around the sun

Ⅰ. if和whether引导宾语从句时，作“是否”讲，一般情况下，二者没有区别，可以换用。但if常用于口语中，whether比较正式。如：

结构：
由于if和whether连接的是一般疑问句，因此要注意把从句语序改为陈述句语序。
一般来说，在宾语从句中if与whether可以互换使用。在口语中常用if。但在特殊情况下，两者不能互换。只能用whether，不能用if引导的情况：
1) 与不定式连用
e.g. I don’t know whether to go to Beijing tomorrow.
2) 与(…)or not直接连用
e.g. I dont know whether or not they can get there on time.
3）在介词后，只能用whether
The thing depends on whether you will arrive at school on time.

or mon gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is becoming more and more popular to celebrate Mother’s Day and Father’s Day in China.
