Dear Earthmen(地球人)，
I enjoy my stay on your interesting planet(星球).
I think I know the life on Earth now and I would like to tell you my ideas.
First of all you live in boxes. Every morning you leave your boxes and get into smaller boxes on wheels(轮子). All these small boxes run around and around, and finally stop to rest. You leave these boxes on wheels and go to very large tall boxes.
After resting all day, you get back in your little boxes. There you sit and look at very small glowing boxes with moving pictures in them.
There is only one thing I don’t know. Some angry boys fought for a little round (圆的) ball. Everyone shouted(大声喊) but they kept fighting. They were angry, because they had to stay in boxes all day, I think.
Thank you for this chance(机会) to get to know you.
Yours,
The man from Mars(火星)
【小题1】How many kinds of “boxes” does the man from Mars tell us？

My sister Sharon and I look very different. She’s tall, and I’m short. She has short curly dark (黑暗的，深色的) hair, and I have long straight blond hair. We both have dark eyes, but Sharon wears glasses, and I don’t. And she always wears large earrings (耳环). I don’t wear earring.
Sharon and I do many things together (一起). We watch movies together, and we often go shopping. We play tennis together every Saturday. Often, people don’t know that Sharon and I are sisters, because we look so different. But we are also good friends.
