二、主句和从句时态一致问题
(1)如果主句是现在的某种时态(包括一般现在时、现在进行时、现在完成时),那么宾语从句的时态可根据实际情况而定。
I remember he gave me a book yesterday. 我记得他昨天给了我一本书。
He has told me that he'll leave for New York tomorrow.他告诉我明天他就动身去纽约了。
(2)如果主句是过去的某种时态(包括一般过去时、过去进行时),那么宾语从句一般要用过去的某种时态(包括-般过去时、过去进行时、过去将来时、过去完成时)。
He told me that he would take part in the high jump.他告诉我他将会参加跳高比赛。
(3)如果宾语从句表示的是客观事实或真理,即使主句是一般过去时,从句也要用一般现在时。
He told me that the earth revolves around the sun.(真理)他告诉我地球绕着太阳公转。
He said that Yao Ming is much taller than him.(事实)他说姚明比他高很多。
三、语序问题宾语从句的语序要用陈述句语序。在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。
What's Kate's e-mail address? Do you know?
=Do you know what Kate's e-mail address is?你知道凯特的电子邮件地址吗?
四、连接词问题(1)当宾语从句是由陈述句转化来时,用that引导。 (that本身无意义，只起连接作用，口语中可省略）。
“She is a good girl,"the teacher told us.
= The teacher told us that she was a good girl.老师告诉我们她是一个好女孩。
(2)当宾语从句是由一般疑问句转化来时,宾语从句用whether或if连接,句尾的标点符号取决于主句。（意为“是否”，不作句子成分，但不能省略）。
“Are you from Japan?"he asked me.
= He asked me if/whether I was from Japan.他问我是不是来自日本。
(3)当宾语从句是由特殊疑问句转化来时,连接词就用原来的特殊疑问词,但从句一定要注意用陈述句语序。（when表时间 where 表地点 why 表原因 how表方式 在从句中做状语）
Could you tell me where they live?
(What which who whom whose 在从句中做主语 宾语 定语）
I don't know what they are gonging to do. 我不知道他们打算干什么。
When did he leave for Japan? Could you tell me?
= Could you tell me when he left for Japan?你能告诉我他什么时候去的日本吗?
五、特殊要点（否定转移和宾语从句简化）
否定转移在主从复合句中,当主句的主语为第一人称,谓语云词是think,believe,suppose 等时,要将从句的否定词转到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。
I don't think he will come with you.我认为他是不会和你一起来的。
宾语从句的简化当宾语从句的主语和主句的主语相同,且主句的谓语动是hope,wish,decide,agree,choose 等时,从句可简化为不定式结构。
I hope that I can receive your e-mail.
=I hope to receive your e-mail.
