[Q]: Article: To most of us,school means classes,teachers,schedules,grades,and tests.But for the children at Sudbury Valley School in Massachusetts,school is very different. Firstly,there are no lessons.All the children,aged between 4 and 19,do whatever they want.There are no teachers--only "staff members".The idea behind this is that you do not need to make children learn,because children want to learn anyway."You do not need to say to a three yearold,'Go explore your environment.'You can't stop them!" says Daniel Greenberg,a founder of the school."But if you make children do what you want all day,they will lose all taste for learning." At Sudbury Valley School,you will permit children to talk,read,paint,cook,work on computers,study French,play the piano,climb trees or just run around.Two boys spent three years just fishing! The other way that Sudbury Valley School is different is that the children can decide the rules.Every week,there is a school meeting where both children and staff have one vote each--even the fouryearolds.They decide the school rules,how to spend the school budget,and even which staff they want and do not want any more. When the school first opened in 1968,people said it would never work.But today,the school has 200 students,and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist.
Question: What is the main topic of the article?
Options: (A) An unusual school. (B) Children's hobbies. (C) A school without rules. (D) Education in the US.

[Q]: Article: A man came home from work late, tired and irritated, to find his 5-year-old son waiting for him at the door. "Daddy, may I ask you a question?" "Yeah sure, what is it?" replied the man. "Daddy, how much do you make an hour?" "That's none of your business. Why do you ask such a thing?" the man said angrily. "I just want to know. Please tell me. How much do you make an hour?" pleaded the little boy. "If you must know, I make $20 an hour." "Oh," the little boy replied, with his head down. Looking up, he said, "Daddy, may I please borrow $10?" The father was furious, "If the only reason you asked that is so you can borrow some money to buy a silly toy or some other nonsense, then you march yourself straight to your room and go to bed. Think about why you are being so selfish. I don't work hard every day for such childish behavior." The little boy quietly went to his room and shut the door. The man sat down and started to get even angrier about the little boy's questions. How dare he ask such questions only to get some money? About an hour or so, the man had calmed down, and started to think: maybe there was something he really needed to buy with that $10 and he really didn't ask for money very often. The man went to the door of the little boy's room and opened the door. "Are you asleep, son?" He asked. "No daddy, I'm awake," replied the boy. "I've been thinking, maybe I was too hard on you earlier," said the man. "It's been a long day and I took out my aggravation on you. Here's the $10 you asked for." The little boy sat straight up, smiling. "Oh, thank you, daddy!" he yelled. Then, reaching under his pillow he pulled out some crumpled up bills. The man, seeing that the boy already had money, started to get angry again. The little boy counted out his money, then looked up at his father. "Why do you want more money if you already have some?" the father grumbled. "Because I didn't have enough, but now I do," the little boy replied. "Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you."

Options: (A) was very happy (B) answered him immediately (C) was not willing to tell him (D) didn't tell him at all

[Q]: Article: We often see wind-horse flags in Tibetan areas. They are long cloths on which pictures of horses and scriptures are printed. People often put these flags on top of houses, or leave them where a vehicle accident happened. They prevent evil spirits from injuring people again. A wind-horse flag can be white, yellow, red, green or blue. These five colors symbolize the five elements that form the world; earth, water, fire, wind and sky. Another explanations that red is the sun, green is the grassland, yellow is the earth, blue is the sky, and white is the cloud. The wind-horse flag originated with a monk who obtained a scripture from India. When he crossed a river, he carelessly dropped the scripture into the water. He quickly saved the scripture and spread it out on a big rock to dry as he sat in meditation . Suddenly violent thunder sounded like drums. The monk felt liberated from all of his sadness, and when he opened his eyes he saw that the scripture had been blown into the sky by a strong wind. Finally, he went straight to heaven. In order to honor the spirit of the monk and the Buddhist scripture, people printed the scripture on a piece of cloth and hung it up between the sky and the earth as though the scripture was flying in the sky. We also know why people put the wind-horse flag on the top of mountains and houses. The Tibetan ancestors had a very great idea about chanting scripture. They thought people not only could chant scripture, but also the five elements. The wind-home flag is a good example of how they use the wind to blow the flag, which means that the wind also chants scripture.
Question: What happened when the monk meditated?
Options: (A) He felt very sad about his mistake. (B) The scripture was blown into the sky. (C) He was punished by the gods. (D) Many wind-house flags were flying.
