A boy called Mario had many friends, and he was proud of it. Whoever he met, he would like to show off(炫耀) how popular he was at school.
One day, his grandpa said to him, “Mario, I know that you don’t have as many friends as you think. Many of them are not true to you.”
Mario thought maybe his grandpa was right. However, he wasn’t sure how he could test whether his schoolmates were real friends or not, so he asked his grandpa. The old man answered, “I have just exactly what you need. It’s in my room. Wait a minute.” The old man left, soon returning as if(好像) carrying something in his hand, but Mario could see nothing there.
“Take it. It’s a very special chair. Because it’s invisible, it will be hard for you to sit on it. However, if you manage to sit on it, you can use the chair’s magic power（力量） to tell who your real friends are.”
Mario took the strange invisible chair to school. At break time he asked everyone to form a circle, and he put himself in the middle, with his chair.
“Nobody move. You’re about to see something amazing，” said Mario. Then he tried sitting on the chair. Having difficulty seeing it, he missed and fell to the ground. Everyone had a pretty good laugh. “Wait, wait,” said Mario, making another try. But again he missed the seat.
Mario didn’t give up. He kept trying to sit on the magic chair. Finally, he did it. This time he felt himself in mid-air.
Then he experienced the magic that his grandpa had been talking about. Looking around, Mario saw George, Lucas and Diana holding him up, so he wouldn’t fall. But some schoolmates whom he had regarded as friends had done nothing but made fun of him. Mario was quite thankful to his grandpa, who helped him test who his true friends were.
【小题1】Mario’s grandpa gave him a special chair to _____.

　　This year 1 twenty-three hundred teenagers from all over the world will spend about ten months in U. S. 2 . They will attend U. S, schools, meet U. S. teenagers, and form 3 of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new 4 and gain a new understanding of the rest of the world.

　　Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George's family. 5 , George's son Mike spent a year in Fred's home in America.

　　Fred, a lively young man; knew little German when he arrived, but after two months' study, the language began to come to him. School was completely different from what he had expected－much 6 . Students rose respectfully when the teacher entered the room. They took fourteen subjects 7 the six that are usual in the United States：There were almost no 8 activities.

　　Family life, too, was different. The father's word was 9 , and all activities were around the family rather than the individual. Fred found the food too simple at first. 10 , he missed having a car.

　　“Back home, you 11 some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”

　　At the same time, in America, Mike, a friendly 12 boy, was also forming his idea. “I suppose I should criticize American school,” he says. “It is far too easy by our 13 . But I have to say that I like it very much. In Germany we do nothing but 14 . Here we take part in many outside activities. I think that maybe your schools are better in training for 15. There ought to be some middle ground between the two.”

I was woken up by a strange sound. I saw something moving by my window. I was terrified and ran downstairs. I found my mom in the kitchen, getting my brother ready for school.
"Mum, did you hear anything? I, uh. I thought I saw an alien."
"Are you all right? Just a dream ! "Mum answered.
Then I went back to my room. As I walked to the window, I cried, I saw a little alien, no more than three feet tall, with big and black eyes. It tried to run between my legs and escape through the window. Although I was scared, for some reason, I squeezed (挤) my legs together in time to catch it. It took out something and hurt me. I felt a terrible sense of nothingness and fainted (晕倒). Then I woke up.
At first, I could hardly move. I wasn't sure whether it was a dream or not. I pulled myself out of the bed and walked downstairs. I saw my mum in the kitchen. She was really getting my brother ready for school, wearing her pink clothes. Then I realized it was just a dream because in my dream she was wearing her work clothes.
From then on, I always dreamt about aliens and all the dreams felt so real. At that time, I really thought maybe I had some kind of relationship with aliens. About two months later, I stopped having such dreams. Later I realized that l used to have those dreams because I always read books or watched TV programs about aliens before I fell asleep!
