    It's a sunny Sunday. Mrs. Green is on a bus. She sees a woman get on the bus with ten boys. All the boys wear (穿) the same clothes —blue coats and black trousers.

    “Are these all your sons?” Mrs. Green asks the woman.

    “Yes, they are,” says the woman.

    “Where are you going?” asks Mrs. Green.

    “My sons want to play in the park.”

    “Why do they wear the same clothes?” asks Mrs. Green.

    “Because it's easy to see them. When I have three sons, I dress( 给……穿衣服) them in the same clothes because I don't want to lose any of them. But now I have ten sons, and I let them wear the same clothes. I don't want to take other boys home,” says the woman.

根据短文理解，选择正确答案。

    Then the white rabbit saw Alice.

    “What are you doing here, Mary Ann?” he asked. “Go home right away and bring me a fan and a pair of white gloves.”

    Alice was too afraid to tell him she was not Mary Ann, a servant. So she ran off.

    “I'll try and find his fan and gloves,” she thought when she ran.

    She soon came to a little house. There was a name on the door, “W. Rabbit.”

    She went inside without knocking on the door. “How strange this all is!” she thought. “I am running errands for a rabbit. Perhaps Dinah will ask me to run errands for her.”

    She ran up the stairs into a little bedroom, and there she found a pair of gloves and a fan. She picked them up and was going to leave when she saw a bottle. It was near a looking glass. On the side of the bottle were the words “Drink me.”

    “I'll drink some,” Alice thought. “Perhaps it will make me grow again. I am tired of being so small.”

    She quickly drank half the bottle. Before she could get out of the little house, she started to grow. Soon, she was so big, she could not move in the room.

    “That was a silly (傻的) thing to do,” she thought. “Why didn't I take the bottle with me and drink from it outside the house?”
