My mother was telling me about how she and her family got their first television when she was a teenager. Of course, it was black and white. She said she only watched it at night. When I was young, we had only about 3 or 4 different channels. My brothers, my sisters and I would sometimes fight about which channel to watch. But we usually enjoyed the same shows.

   Nowadays, we can get hundreds of channels on TV. There are channels with old movies, cooking, fishing and so on. It's amazing! I wonder how much my brothers, my sisters and I would fight if we had hundreds of channels when I was a child. Of course, we had only one television set. These days I notice families with 2 or 3 or more television sets in their homes. I guess it stops people from arguing over which channel to choose.

    Last weekend John went camping with his parents and his sister, Mary. They took a tent, sleeping bags, water and food. They arrived at the campsite at about three on Saturday afternoon. First they went cycling along thelake for more than two hours. When it was getting dark, they returned and began to enjoy their dinner. Everything tasted delicious.

    Soon it was time to put up the tent. John helped Dad pull the tent out of the bag. Then, they found there were no poles (杆子) to hold it up.

    "Oh," cried John. "I forgot to bring the poles. What could we do?"

    Dad looked up at the sky. There were many stars in the sky. The night was clear and the air was warm.

    "It's OK," Dad said. "We don't even need a tent." He put the sleeping bags on the ground.

    They slept well that night. The sun was shining on them when they woke up the next morning.

    "It is my best camping trip," said John.

    It was a fine day. Sherlock Holmes invited his best friend Doctor Watson to go camping with him. They found a nice hill and put up their tent. Then they went fishing and climbed the hill. {#blank#}1{#/blank#} They began to chat (聊天) happily.

    "Watson, look up into the sky and tell me what you can see." said Holmes.

    "{#blank#}2{#/blank#}"Watson replied.

    Holmes asked again, "What does that tell you?"

    Watson thought for a while, "It tells me that there are tons of galaxies (星系) and planets."

    Holmes continued asking, "{#blank#}3{#/blank#}"

    Watson smiled. "It tells me that God is great and powerful. At the same time, {#blank#}4{#/blank#}"

    "Oh, I think so. Is that all?" asked Holmes.

    "No, as for the weather, {#blank#}5{#/blank#} What does it tell you?" Watson said.

    Holmes laughed. "Someone has stolen our tent."
