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 1.
    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 2.
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 3 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 4 to get through that?” I almost laughed because asking questions really was starting to become a 5.
    I thought I had made it safely through the whole day, 6 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 7 again. “Well, I hope you went to school,” he said.
    “Uhhh … why would you think otherwise?” I asked. My parents exchanged another 8  and were becoming annoyed.
    “Do you think questions are a good way to train your mind to be active?” I asked.
    “It 9 the question,” said my father. “Some questions are asked for 10 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 11.
    “I think it worked 12!” my father said. “You made a discovery, didn't you? What matters is that you have put your idea into practice.”

Try to help your dog relax

    It's a Saturday morning. You rush through breakfast, walk the dog, and then get to soccer practice on time. A few hours later, you return home, only to find that the dog has made your bedroom untidy.  ____ Your favorite sports shoes are in poor condition.

    Before you get angry, stop and think. Your dog wasn't misbehaving (行为不端) just for the fun of it. ____ Some dogs just feel nervous when left alone. It's called separation anxiety (分离焦虑).

    Think of it this way: Dogs can't ask where you're going or when you'll be back. They can't call you on the phone. ____ Since you're not there, they need to find you. Dogs may suddenly develop separation anxiety. But with practice and patience (耐心), you can teach your dog to be comfortable being left alone.

    Put on your jacket, and then sit back down. Open and close the door, and then sit down. After a while, walk out the door for 10 seconds, then 20, then a minute and so on. ____

    Besides, you can also try the following ways:

    Teach your dog a word or action that you use every time you leave, which tells your dog you'll be back.

    Help comfort (安慰) your dog by leaving a piece of clothing that smells like you.

    Before you leave, give your dog a toy. ____
