The earth did not always look the way it does today. Once the sea covered mud of the land. Then mountains pushed up. They pushed up through the water. Land from the bottom of the sea became mountaintops. Seashells and fish bones were pushed up, too. They were far away from seawater. They were left high and dry.
The seashells and fish bones were covered with soft mud and sand. The mud became hard. It turned to stone. The shapes of the shell and bones were pressed into the stone. These stones are called fossils.

Your friends might be in Australia or maybe just down the road, but they are all just a few clicks away. Life has changed for millions of young people across the world who now
make friends online. Whether you use chat-rooms, QQ, MSN or ICQ, you are a member of this group.
“I don’t often talk with my parents or grandparents, but I talk a lot with my old friends on QQ,” said Fox’s Shadow, the online name used by a girl student in China. “Most of my classmates use QQ af ter school.”
QQ is the biggest messaging service in China. A record from Tencent, the company which developed QQ, shows that 4 million people used it one Saturday night in October.
And probably Fox’s Shadow was one of them. “I log in(登陆) on Friday nights, and Saturday or Sunday when I feel everything around me boring. I usually spend about 10 hours chatting online every week,”she said. “But I never talk with strangers, especially bo ys or men.”
Even though she likes chatting, she is careful about making friends with strangers online. “You don’t know who you are talking to. You should always be careful about whom you believe on line.”
Many people would like to meet offline when they feel they have got to known to someone very well. Fox’s Shadow once met one of her online friends face to face. It was a girl who was a football fan like herself and they went to a football match together.
A 16-year-old Beijing boy, named Simon online, dislike QQ users. “I used to chat on QQ, but I found that most people were talking about foolish things,” he said. Now he chats online in English, using MSN. “I only chat online because I’ve got friends in Jap an, the US and Singapore,”he said. “I want to learn more about foreign cultures(文化).”But he spends little time chatting on QQ as he sees it as a waste of time and money.
“If you are really addicted to(上瘾) it, sometimes you can’t give your mind to your lessons,”he said. “And friends in your real life are always more important than those so-called friends you meet online.”
41. People meet face to face offline when they think they ____.
A. have known each other well.
B. have the same interest.
C. have enough free time
D. have nothing to do
42. Fox’s Shadow thinks QQ is ____.
A. the biggest messaging service in China.
B. a good place to spend her time when bored.
C. a safe place to chat with strangers.
D. the best place to make friends.
43. From the passage, we know “…they are all just a few clicks away” means ____.
A. it is wonderful to see your friends by clicking
B. it is easy and fast to get in touch with your friends
C. it is possible to live much closer to your friends
D. it is popular to make friends online
44. Which of the following sentence is TRUE according to the passage?
A. All the people on QQ are talking about foolish things.
B. Chatting online is a waste of time and money.
C. We should always be careful about boys or men online.
D. We should think more of our friends in real life.
