Mr. Black is short-sighted（近视的）but he doesn’t wear glasses, because he thinks it is not cool to wear glasses.

It is Saturday and it is fine today. Mr. Black likes sunny days and he wants to take a walk. He puts on（戴上）his black hat, takes his yellow bag and then goes out of his house. He walks on the street and looks around. The sun is shining and the birds are singing in the tree. Mr. Black feels very happy. Suddenly, a strong wind blows away his hat. “Oh, my hat!” Mr. Black begins to run after it. He runs and the hat “runs”, too. Mr. Black feels surprised（感到惊讶的）. An old man shouts（喊叫）at him from a window.

“Hey! What are you doing?”

“Running after my hat!”

“Your hat? You are running after my black cat.”

A very big Lost and Found Office is at Baker Street in London. Do you know how many things there are in the office now? About 250,000!

You can see all kinds of things there. Most of them are common (普通的) things like books, bags, clothes and keys. But some are dear things like phones, laptops (笔记本电脑) and watches.

Where do so many things come from? People often find them on trains, on buses and in taxis. The office marks (作标记) them with different colors. Red is for the things from a taxi, white is for the things from a bus and yellow is for the things from a train.

How many of the things can go to their owners (主人)? Many of the things are there for a long time, but no one comes to get them. If the office can’t find the owner of a thing in three months (月), they will give it to a charity (慈善机构) to help more people.
