初中英语语法宾语从句讲解
小口诀：
宾语从句三注意，时态语序引导词；主句一般现在时，从句不需受限制；
主句一般过去时，从句须用相应时；陈述转化that引，一般疑问用if/whether,
特殊问句疑问词，引导词后陈述式。
一．基本讲解 来源：直接引语变间接引语
概念:在句中担当宾语的从句叫宾语从句。
Eg: He said,“I am good at drawing”.
He said he was good at drawing. (动词宾语)
1.引导词
(1) that引导宾语从句时，通常用陈述句充当, that可省略。
Eg: She said,“I want to go there
” She said (that) she wanted to go there.
(2) whether 或 if 引导的宾语从句,由一般疑问句/选择疑问句充当，陈述语序。
Eg: “Are you interested in geography?” she said.
She asked if/whether I was interested in geography.
I wonder if /whether she has told the new to Li Lei .
I’m not sure whether he will come or not.
注意：一般情况下，whether 和if 可以互用， 但有些情况例外
a. 介词短语后只用whether 不用if
eg: We are talking about whether we'll go on the panic.
b. 引导词与动词不定式或or not 连用时，只用whether.
eg:I can’t say whether or not he will come on time

宾语从句
在复合句中用作宾语的从句叫做宾语从句。它在句中可以充当及物动词、介词或形容词的并与。宾语从句的三大考点即：引导词、时态和语序。
一、宾语从句的引导词
1.that引导的宾语从句
当宾语从句是陈述句时，用连接词that引导，that在口语、非正式文体中常被省略。
He says(that) he has been to Shanghai twice.他说他去过上海两次。
She said (that) she went to the park last week.她说她上周去公园了。
2. 特殊疑问词引导的宾语从句
当宾语从句是特殊疑问句时，特殊疑问词就是引导词。特殊疑问词引导的宾语从句疑问词不可省略。
Could you please tell me where we will have a meeting?你能告诉我们将在哪儿开会吗？
I wondered what I should do next.我想知道下一步该做什么。
3. if或whether引导的宾语从句
（1）当宾语从句由一般疑问句变来时，要用if或whether引导，意为“是否”。 If和whether只起到连接作用，不充当句子成分，一般情况下可互换，但if常用于口语中，whether常用于正式文体中。
I want to know if /whether he is waiting for me.我想知道他是否在等我。
Could you tell me if /whether you have been to Australia? 你能告诉我你是否去过澳大利亚吗？
（2）下列情况下一般只能用whether：
①与or not连用时
I don’t know whether he likes the movie or not. 我不知道他喜不喜欢这部电影。
②作介词的宾语时
Everything depends on whether we have enough time.一切取决于我们是否有足够的时间。
