Passage 4
From the world’s heaviest apple, the oldest lady to the world’s smallest dog, these are all parts of a group of the world’s strangest people and things. And they are all in the Guinness Book of Records(《吉尼斯记录》).
The book is going to celebrate its birthday this August. It began exactly half a century ago. And it’s always one of the best selling books in the world.

So Beaver believed that people must have different ideas. So, he decided to start a book to record the world’s truly greatest people and things in it!
The newest book came out last Tuesday. This book has a lot of interesting records. Here are two:
☆ A British dog, Whitney, is the world’s smallest dog. It’s only 76mm tall.
