What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects(建筑师) believe that they are all possible. The only thing for sure is that the houses will be as green as possible.

    "My dear lady," says Holmes. "You're shivering. Are you cold? Do you want a cup of hot tea?"

    "I'm not cold," the woman replies, "I fear for my life!"

    "We are here to help you. Don't worry about anything. I don't know you. But I know many things about you. For example, I know how you travel. You came to London by train. You also ride to the train station on a horse-drawn wagon(马车)."

    "Why, yes. You're right. But how do you know these things?"

    "I see a return ticket in your glove. I see fresh mud on the left arm of your dress. Now tell us your problem."

    "My name is Helen Stoner," she states, "My mother and father are dead. I am living with my stepfather, Dr Grimesby Roylott. He comes from a rich family. But they are no longer rich. They have nothing except a small piece of land and a huge old house. We are living in the house. Dr Roylott is using my mother's money for expenses(开支). Part of it was for my sister and me. It was for our marriages."

    Holmes is sitting in his chair. His eyes are closed. He is listening carefully to Helen's story. He hears every detail(细节).

    Helen continues. "My stepfather has no friends. He fights with everyone. He is strong and gets angry quickly. Everyone is afraid of him."

    "He has no friends at all?" asks Holmes.

    "No. He talks to no one except the gypsies. They are poor people who travel from place to place. A band of gypsies is staying on our land right now."

    "Are you and your sister afraid of the gypsies?"

    "My dear Mr Holmes. You are making me so sad. My sister is dead. That is why I am standing here in this room."

The most positive(乐观的) person I have ever seen is my dad! He is so positive that I do not1 hearing a single word from him which is related(相关的) to hopelessness!

Unlike most moms and dads, my dad never says things that make me feel2 He is always there to give me encouragement and help. 3 I do wrong things, he always tells me what's right in a positive way. For example, if I am in4 he often tells me to open the books he bought me. Then he asks me to read the 5 that can help me with the problems I'm facing. After that, we have a6 together. 

Even though I'm not always a good kid, my dad7 shouts or gets angry with me. I know that he's8 a day—a day when I grow up and understand things in my life. 

I can see the reason that he is so positive is because he believes in9 . And he believes that whatever10 , it is under control. So we have nothing to worry about. Be positive!
