B
Have you ever done something foolish that made you feel so embarrassed（尷尬的）?
   Well, that’s exactly how I felt. On a Saturday morning last autumn．I had gone to town to do some shopping and as I was on my way home，it suddenly began to rain. I at once ran into a nearby phone box since I didn’t have an umbrella．It was raining so heavily that I have to stay in the phone box until it stopped．
   A few moments later，I saw a young man walk up to the phone box，wearing a yellow raincoat and holding a box. I didn’t want to go out into the rain，so I picked up the phone and pretended I was talking to someone. I thought the man would go away，but he didn’t. He just waited in the pouring rain，watching me. I had to wave my hands about and act as if I was deep in conversation.
   Luckily，it began to stop after about ten minutes．“Okay，Mum，” I said loudly into the phone，“I’ll see you later Bye!” I put the phone down．picked up my shopping bag and walked out of the phone box “I’m sorry I took so long,”I said to the man．
   “Oh, I don’t want to use the phone,”he replied．smiling．“I’ve just come to repair it. It’s out of order．you see.” I felt myself go bright red in the face and I hurried away with my head down，feeing a complete fool. That was certainly one of the most embarrassing moments of my life!

How could you tell time if there were no watches or clocks anywhere in the world?
    The sun was probably the world’s first clock, except in the far north, where the Eskimos(愛斯基摩人) live. There, it’s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun for a clock. Even today, if you don’t have a clock, you still know that when the sun shines, it’s day, and when it’s dark, it’s night. The sun can also tell you if it’s morning, noon or afternoon.
    People who live near the sea can tell time from the tides. In the daytime, for about six hours, the water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every 24 hours.
    Seamen on a ship learn how to tell time by looking at the moon and the stars. The whole sky is their clock.
    In some places in the world the wind comes up at about the same time every day or changes directions or stops blowing. In these places the wind can be the clock.
    A sand clock is an even better clock. If you had find dry sand in a glass shaped like the one in the picture, you would have what is called an hourglass. The sand in the hourglass goes from the top part to the bottom part in exactly one hour. And when it is turned over, the sand will take another hour to go back again.
