各位英语大侠，求救

[1]. Tom is the uncle of Sally
[2]. Mary is the aunt of Tom.
[3]. My uncle is Peter.

A dictionary always needs to be at hand whenever I'm doing my English homework.
dictionary: 字典
I have been keeping a diary for several years, and it's went from a plain habit to a great pleasure in my life.
diary: 日记

1.同义句转换
（1）Tom is Sally's nephew .

（2）Tom is Mary's nephew .

（3）I' m Peter's nephew.

2.用diary,dictionary造句,要简短并介绍出它们各自的作用.

A diary is something you write everyday about your life.

A dictionary is something to which you can refer when you meet

new words.

1.Tom is Sally's nephew<外甥>。
2.Tom is Mary's nephew.
3.I am Peter's nephew.
这3句说的是一个意思。

diary是日记，dictionary是字典。
I keep a diary everyday.我每天都写日记
My dad bought me a dictionary.我爸爸给我买了本字典。

符合要求，简单实用
