One night, I wondered what it would be like if I only asked questions. I decided that no matter what anyone said to me the next day, I would reply only with   36  .

I loved to read about scientists and their discoveries, and I knew that scientists always started their research with a question. I hoped that I could become a scientist. Maybe by asking questions, I could train my mind to be   37  .

  I survived the morning easily. “Is there any egg?” I answered when my mother asked what I wanted for breakfast. “Is this seat taken?” I asked when my friend Mike asked where he was going to   38   on the bus.

In the classroom, Mr. Black spoke slowly and clearly while I listened carefully. The problem had been part of my homework the night before. I wrote the answer on the board, “Could the answer be 361?”

  Mr. Black smiled and nodded. I thought,“How did I   39   to get through that?” I almost laughed because asking questions really was starting to become a   40  .

  I thought I had made it safely through the whole day,   41   what I had come to consider my experiment blew up at the dinner table when my dad asked me about my day. “What do I always do?” I replied.

My parents looked at each other. My father   42   again. “Well, I hope you went to school,” he said.

    “Uhhh … why would you think otherwise?” I asked. My parents exchanged another   43    

and were becoming annoyed.

   “Do you think questions are a good way to train your mind to be active?” I asked.

“It   44   the question,” said my father. “Some questions are asked for   45   information. Those are good mind-training questions. Sometimes, people use questions to get the other person to say something. Sometimes people ask questions to get someone to agree with them. Those questions don’t really achieve anything.”

   “I guess my experiment didn’t work,” I said, and I told my father about my   46  .

“I think it worked   47  !” my father said. “You made a discovery, didn’t you? What matters is that you have put your idea into practice.”

Mike didn’t do his English homework. The teacher asked him    31  . “I’m sorry, I   32  .” “But why did you forget?” “It didn’t seem   33   or important,” said Mike. “Are you going to punish (懲罰)me?” asked Mike. “   34  . The punishment is for me. I didn’t teach you well,” said the teacher.
“Thank you,” said Mike. “You are the best    35  in the world. I can never know as much as you , but you taught me a lot.” “How can I be a good teacher if the students do not know more than me? I will not succeed until that happens,”   36  the teacher.
Mike’s   37   teacher was a strict（嚴(yán)厲的） man.. Every day Mike played the same piece of music,and the teacher said it was not good and he must practise   38  . After two years of hard work, Mike left and felt sad.   39  when he played it in public, everyone said it was perfect, and he found he could play other pieces of music easily.   
What do you think of these two   40  ?

When are you an adult (成年人)？

When do you think you are an adult ? Maybe different __31_ have different ideas.

Now let’s see what some American teenagers(青少年)say .

Sam: In  32 idea ,you are an adult at the  33  of 18. That’s when you can vote(投票)。You can help to   34  who rules(統(tǒng)治)the whole country .That’s also a grown-up does! My grandfather couldn’ t vote   35 he was 21.They changed（改變） it to 18 in 1971.

Jenny：I don’t 36  it’s hard to say . I can drive a car at 16, can’t I ?When you have a driver’s licence , you can 37 it to people to tell them your age for all kinds of things .  38    sixteen must be the age when you change from a  39  person to an adult.Because you can tell others you are not a  40   any more .

Suzie : Well , I think there is  41   wrong with American laws for when young people can  42  things . I can vote at 18 and drive at 16. So you would think 18 is a grown-up,  43  16 isn’t .But then I can’t drink wine（酒）until I’m 21 ! If I’m 44   an adult at 18, how can people stop me from  45   a cup of beer in a bar ?

Tom and Fred were talking about the year 2050.

　　“I don’t know,” said Fred. “What do you think?”
　　“Well, no one knows. But it is __37__ to guess,” said Tom. “In the year 2050 everybody will carry a pocket (袖珍) __38___. The computer will give people the __39__ to all their problems. We shall all have telephones in our pockets,__40___ . And we’ll be able to talk to our friends all over the world. Perhaps(也許) we’ll be able to ___41__ them at the same time. Machines will do ___42___of the work, and people will have more__43___. Perhaps they will work only two or three days a week. They will be able to fly to the moon by spaceship and spend their holidays there.”
　　“I’m very _44__to hear that. I hope to fly to the moon. And I hope I’ll be able to live _45___,” said Fred. “Won’t that be interesting? Just like a fish.”
