宾语从句：在句子中起宾语作用的从句叫宾语从句。
宾语从句的时态：
（1）如果主句是现在时，那么从句可以根据需要选择任意时态；
练：我记得他昨天给了我一本书；
I remember that he _______ (give) me a book yesterday.
他告诉我他明天要动身前往纽约了；
He tells me that he ____________(leave) for New York tomorrow.
我发现他正在看别人的信件。
I find that he ___________(read) others’ letters.
（2）如果主句是过去时（某种时态），那么从句一般要用过去的某种时态（一般过去时，过去进行时，过去将来时）
练：他告诉我他将会参加跳高比赛；
He told me that he __________(take) part in the high jump.
（3）如果宾语从句表示的是客观事实或真理，即使主句是过去时，从句也用一般现在时；
练：老师告诉我们地球绕着太阳转
Our teacher told us that the earth ________(travel) around the sun
宾语从句的引导词：
引导词 | 引导词的作用 | 例句 |
that | 本身无意义，只起连接作用，在口语中可省略； | He said (that) Kate was good at swimming. |
what, which, who,whose等连接代词 | 在从句中作一定的成分，如主语、宾语、定语等； | I don’t know what they are going to do. He asked me whose book this was. |
when(表时间)，where(表地点怎么看手机的系统)，why(表原因), how(表方式)等连接副词 | 在从句中作状语 | Could you tell me where you are from? |
if/ whether | 意为“是否”，不作句子成分，但不能省略； | He asked me whether / if Miss Gao was a teacher. |
1、当宾语从句是由陈述句转化而来时，用that引导，口语中往往省略；
“She is a good girl,”the teacher tells us.
→The teacher tells us _______ she is a good girl.
【注意】引导词that用于下列情况时不能省略；
（1）当宾语从句的主语是that时；
例：He says that that is a useful book.
（2）当从句前有插入语时；
例：It says, on the car, that it is made in China.
（3）当宾语从句中含有主从复合句时；
例：I’m afraid that if you lost the book, you must pay for it.

（4）当有两个或多个宾语从句由并列连词连接时，除第一个从句中的that可以省略外，其余从句中的that都不可以省略；
刘逸云是男的还是女的 例：He said (that) the film was very interesting and that he enjoyed seeing it very much.
2. 把一般疑问句变为宾语从句时，用whether 或if引导；
练： “Are you from Japan?” he asked me.
→He asked me __________ I _______(be) from Japan.
“Do you like watching TV?” he asked me.
→He asked me__________ I ______(like) watching TV.
【注意】
a. 一般情况下，whether和if可以互换。但是以下三种情况只能用whether.
①当宾语从句中出现了 or not时
例：Let me know whether you can come or not.
②当在介词之后，做介词宾语时
例：I’m thinking of whether I should go fishing ./ It depends on whether it will be sunny tomorrow.
③当与不定式连用时
例：I don’t know whether to accept or refuse. / I’m not sure whether to play basketball or go home.
b. if 在宾语从句中，意为“是否”，等同于whether；
在条件状语从句中，意为“如果”，时态遵循“主将从现”；
3、把特殊疑问句变为宾语从句时，连接词就用原来的特殊疑问词，但一定要注意用陈述语序；
练：高中家长会发言稿When did he leave for Japan? Could you tell me?
→ Could you tell me _______ he _______(leave) for Japan?
Who is our English teacher ? Do you know?
→Do you know_____our English teacher_____
宾语从句的语序
宾语从句的语序要用陈述句语序，即：主语+谓语动词；把两个独立的句子连成一个含有宾语从句的复合句时，要特别注意从句的语序，即按照主语、谓语的顺序；
【注意】：将助动词did/do/does, will, be,情态动词提到主语前，则成为疑问语序，变成宾语从句后，要将疑问语序变为陈述语序，要将助动词去掉，情态动词回归到主语之后，动词之前；
练： What’s Kate’s e-mail address? Do you know?
→Do you know ________ ________ email is?
Where is he going? I want to know.
→I want to know where _______ _______ going?
