Answer 1

1. Tell Mary we'll be late for dinner this evening.
tell 谓语；Mary 间接宾语；we'll be late for dinner this evening 直接宾语 （从句）
2. I am afraid I don't understand.
I 主语； am afriad 谓语；I don't understand 宾语（从句）
3. I said I would be at your house at six o'clock.
I 主语； said 谓语；I would be at your house at six o'clock 宾语（从句）
4. I don't know when I'll finish.
I 主语； don't know 谓语；when I'll finish 宾语（从句）
5. My wife wants to know if Mary needs any help.
My wife 主语； wants to know 谓语；if Mary needs any help 宾语（从句）
6. I don't know what you're talking about.
I 主语； don't know 谓语；what you're talking about 宾语（从句）

Answer 2

1,祈使句，宾语从句做了tell的双宾语中的直接宾语。
2，宾语从句，I don't understand,做了afraid的从句。在afraid 后面可以加that
3，虚拟语气的宾语从句，名字是说：我告诉过你我6点钟能到你家，（其实没有到你家），可能是两人吵架时，一个人说：“不来我家没关系，你最起码得告诉我什么时候到呀”。题干来回答， 就是完美无缺。
4，when 引导的从句，我不知道我什么时候可以完事。
5，if 引导的宾语从句，if表示是否。我老婆想知道Maryl是否需要帮助。
6，what 引导的宾语从句。我不知道你们在说什么。

希望对你有帮助。

1 tell sb. sth.典型的tell双宾语从句
sb.:Mary sth.:we'll be late 句中还有一时间状语从句即：this evening.
2 I am afraid I don't understand.
典型 主谓宾。主语：I 谓语：are afraid 宾语从句：I don't understand
3 典型 主谓宾..主语：I 谓语：said 宾语从句:I would be at your house 时间状语从句:at six o'clock
4 主谓宾 主语：I 谓语：don't know 宾语从句when I'll finish(这里时间状语作宾语用)
5 主谓宾结构 主语：I 谓语：wants to know sth.这里sth.又做know的宾语。
6 主谓宾结构 主语：I 谓语：don't know 宾语从句：what you're talking about（陈述语气）
