4Can you show me the house where LuXun lived?
5I will never forget the day when we parted.
6I don’t know the reason why he left without telling me.
7The boy whom I spoke to just now is my brother.

3先行词前有序数词或形容词的最高级
This is the best book that I have ecer read.
二:关系代词前有for 时只能用which.
This is the magazine for which you ask.
宾语从句
一:含义:在复合句中起到宾语作用的从句叫宾语从句。
Tom said he bought a new computer last night.
二:宾语从句的引导词:that, if, whether, who whom what which, whose, where, when, how, why.
1由that 引导的宾语从句表示陈述语气,that 没有任何含义可省略不写。
I think(that Mary is the best student in her class.
2由if 或whether引导的宾语从句,翻译为是否。
She asked me if/whether she could join us.
注:当宾语从句中有or (not 连用时,只能用whether.
I’d lik e to know whether she will go or not.
三:宾语从句的时态
宾语从句的时态应与主句保持一致“

如果宾语从句叙述的内容是自然现象,客观真理,其时态不受主句限制,要用一般现在时。
She said that the sun rises in the east.
四:宾语从句的语序
宾语从句必须使用陈述句的语序即:引导词+主语+谓语+其他
When did the train leave? I want to know.
I want to know when the train left.
She asked me if I would go to the park tomorrow.
Tony want to know where she will go next week.
注:如果宾语从句的引导词恰好在从句中做主语,则句子保持原有的结构
We don’t know what has happened to him.
注:在宾语从句中,当主语的谓语动词是think, believe, imagine, suppose, 并且主句的主语是第一人称时,宾语从句的否定词要移到主句中,即:否定前移。
I don’t think she is right. 我认为她不对
I don’t believe he can come back soon. 我认为他不会很快回来。
注:当这些否定前移的宾语从句变反义疑问句时,反义疑问句的主谓应和从句保持一致。
I don’t believe he is a student, is he?
We don’t think Tom is right, is he?。
