I could not pass the truck because there were two cars coming near from Newton. My taxi hit the truck, and some glass cut my left hand.
TOM: I was watching the traffic about a kilometer from the airport. A truck was going to Newton. It was not going very quickly. There was a taxi about two hundred meters behind the truck. It was going fast. When the truck slowed down, the taxi hit it. The taxi driver was not looking at the truck. He was looking out of the window at something. My friend saw the accident, too.

【小题1】How many people are mentioned in the story?

Not only women wear skirts. Men can wear them, too. In Scotland (苏格兰), men wear a kilt – a kind of skirt. The kilt is their national dress.
The kilt has checks (方格) and different colors, like red or blue. Each family in Scotland has its own colors. How did the Scotsmen (苏格兰男人) start to wear kilts. There is a story about it. Rawlinson had some workers from Scotland in his office and he thought their clothing got in the way of their work. So he cut their clothes into a shorter skirt.
Today, they usually only wear them at weddings (婚礼) or big dinners. Only a few men wear a kilt every day. Scotsmen also wear kilts in big parties. The policemen still have skills as the dress uniforms, but they don’t wear them to catch the thieves.
