宾语从句是用一个句子作宾语，即该句子的宾语是至少有一个主谓结构。
举个例子：
Li Jiayuan told me a story. 宾语
Li Jiayuan told me that she was a beautiful girl.宾语从句
that 是引导词，that 后是宾语从句，是陈述句语序。
记住这2点（1.that是引导词；2.从句语序是陈述句。）
a:写出宾语从句：按照写英语句子的方法来写宾语从句：
一、14年前，李嘉媛的妈妈在垃圾堆旁边发现了一个女孩在哭.
S1：找关键词，并且发现“发现”的后面需要一个句子来表达，也就是需要宾语从句。关键词是find.
S2: 从左往右考虑：
1.考虑主句的主谓， 用以前写句子的方法：
句型：宾语从句的陈述句句型，所以结构是主谓；
人称：第三人称；
时态：一般过去时，所以不用单三。
所以：Li Jiayuan's mother found
2.根据要表达的意思选用引导词，从句的意思是一个肯定式陈述句，所以用that来引导。
3.以写句子的方法来写宾语从句：
3.1 句型：从句是陈述句句型，所以结构是主谓；
人称：第三人称；a girl
时态：宾语从句的时态选择方法：
https://www.jianshu.com/p/c61ced04bd3c
a girl was crying
3.2 考虑名词，形容词，副词……
3.3 写出宾语从句：
Li Jiayuan's mother found that a girl was crying next to the garbage dump 14 years ago.
为了句子好理解，把时间状语放在句首，
14 years ago，Li Jiayuan's mother found that a girl was crying next to the garbage dump 14 years ago.
注意：在口语之中，此时的that 是可以省略的。
二：我想知道李嘉媛是否将过来。
S1：找关键词，并且发现“知道”的后面需要一个句子来表达，也就是需要宾语从句。关键词是wonder.
S2: 从左往右考虑：
1.考虑主句的主谓， 用以前写句子的方法：
句型：宾语从句的陈述句句型，所以结构是主谓；
人称：第一人称；
时态：一般现在时，所以不用单三。
所以：I wonder
2.根据要表达的意思选用引导词，这里要表达的意思是“是否”所以要用whether来引导。

3.以写句子的方法来写宾语从句：
3.1 句型：从句是陈述句句型，所以结构是主谓； Li Jiayuan come
人称：第三人称；Li Jiayuan
时态：宾语从句的时态选择方法：
https://www.jianshu.com/p/c61ced04bd3c
因为主句是一般现在时，所以从句就要根据需要选择时态，这里应该选在一般将来时：
Li Jiayuan will come
3.2 考虑名词，形容词，副词……
3.3 写出宾语从句：
I wonder whether Li Jiayuan will come.
4.句首字母大写，句尾用什么标点符号呢？
三、我们对于谁将在这次考试中获胜非常感兴趣。
四、我们不知道为什么李嘉媛为什么学习这么刻苦。
b.宾语从句的否定：一般在从句中否定，而think，believe，suppose，expect等动词后的宾语从句要否定前移。
例如:
I don’t think you are right.
I don’t believe they have finished their work yet.
I don’t suppose he cares，does he？ 我想他不在意，是吗？
S1：找关键词，并且发现“知道”的后面需要一个句子来表达，也就是需要宾语从句。关键词是wonder.
S2: 从左往右考虑：
1.考虑主句的主谓， 用以前写句子的方法：
句型：宾语从句的陈述句句型，所以结构是主谓；
人称：第一人称；
时态：一般现在时，所以不用单三。
所以：I wonder whether
2.根据要表达的意思选用引导词，这里要表达的意思是“是否”所以要用whether来引导。
综上，
宾语从句引导词用法总结如下：
注：1.引导词that可以省略 2.只有whether 可以 和or not 连用，if不能
三、宾语从句的语序
凡是从句都必须使用“主语在前，谓语在后”的陈述语序，宾语从句也不例外，也就是说宾语从句的语序必须是“引导词+主语+谓语+其它”。例如：
误：Could you tell me where is the bus station?
正：Could you tell me where the bus station is?
四、宾语从句的时态一致
1、 当主句为一般现在时或一般将来时的时候，从句可以根据需要选择相应的时态，不受主句的影响;主句为一般过去时，从句要用相应的过去时态。例如：
I want to know what time he ate his breakfast.
我想知道他今天早晨几点钟吃早饭的。
They will tell us that they have been able to look after themselves.
他们将会告诉我们他们已经能照顾自己了。
I asked what my father was doing then.
我问那时我爸爸在干什么?
2、 当宾语从句表述的是客观真理或自然现象是，宾语从句的时态不受主句的时态的影响，仍然用一般现在时。如：
He said the moon moves round the earth.
他说月亮围着地球转。
She asked whether light travels faster than sound.
她问光速是否比声速快。
五、宾语从句的简化
由特殊疑问词引导的宾语从句中的主语与主句的主语或宾语相同时常常可以将宾语从句简化成“特殊疑问词+动词不定式”这种结构。有时候由that引导的宾语从句也可以用动词不定式或者动词的ing形式来简化。如：
Can you tell me how I can get to the post office?
= Can you tell me how to get to the post office?
She don’t know whether she should go there with them or not.
= She don’t know whether to go there with them or not.
He can remember that he has climbed the tall tree.
= He can remember climbing the tall tree.
六、宾语从句的否定转移及其它
1、当I think/believe/guess等一些看法的词后面所接的宾语从句是否定句时，习惯上否定主句，采用“I don’t think/believe/guess+肯定形式的宾语从句”这种结构来表达。如：
我认为明天她不会来。
误：I think that she won’t come tomorrow.
正：I don’t think that she will come tomorrow.
2、 对I think/believe/guess等动词后面所接的宾语从句进行划线部分提问时，要用“疑问词+do you think /believe/guess+宾语从句的剩余成分?”这种结构来表达。如：
你认为谁将在会上发言?
误：Do you think who will speak at the meeting?
正：Who do you think will speak at the meeting?
对于宾语从句，中考怎么考？

想一想，一个宾语从句的顺序：
S1：引导词
1.引导词that可以省略 2.只有whether 可以 和or not 连用，if不能；根据回答选择特殊疑问词作为引导词，并且疑问词在从句中做成分；例如：地点就用where，时间就用when。
S2:从句句型：用陈述句语序：主谓宾；
S3：从句时态：特别注意：主句的情态动词用过去式，是为了表示委婉，而不是表示过去时。
S4：从句能否用不定式代替?
1、 当主句为一般现在时或一般将来时的时候，从句可以根据需要选择相应的时态，不受主句的影响;主句为一般过去时，从句要用相应的过去时态。例如：
I want to know what time he ate his breakfast.
我想知道他今天早晨几点钟吃早饭的。
They will tell us that they have been able to look after themselves.
他们将会告诉我们他们已经能照顾自己了。
I asked what my father was doing then.
我问那时我爸爸在干什么?
2、 当宾语从句表述的是客观真理或自然现象是，宾语从句的时态不受主句的时态的影响，仍然用一般现在时。如：
He said the moon moves round the earth.
他说月亮围着地球转。
She asked whether light travels faster than sound.
她问光速是否比声速快。
