When he was a little child, Andrew had a serious bad habit of sucking（吮吸） his fingers all day long, especially when he had nothing interesting to do: when he was sleeping, when watching TV, when sitting on the sofa and so on. At the beginning, his parents didn't think it was a bad habit.

Therefore, as time goes by, the boy couldn't give up his habit. Now, in his twenties, Andrew seems to have developed the bad habit into another one: he always bites his nails(指甲). He cannot stop biting his nails all the time. There're moments when he even doesn't know that he is doing it. He realized it was a problem and this worried him a lot. Some of his friends told him about this bad habit, and he stops for a while. But then, if he isn't busy doing something, he starts biting his nails again!

In fact, there're a lot of bacteria(细菌) in your nails and they can cause some disease. Also, the nails will become ugly and hard to recover. The worst thing is that this bad habit will bring the mental illness（心理疾病）. If people cannot correct it in time, it can affect man's mental health.

In short, bad habits are very worrying, especially when the person with the habit is in public and cannot stop himself or herself doing it. Still, there must be ways to give up these bad habits and these people should try their best to stop doing them.

    Many expressions(表达方式) we use in American English come from movies and books. Today we will learn some expressions from Lewis Carol's famous book Alice's Adventures in Wonderland. This book is better known as Alice in Wonderland.

    The story is about a young girl falling for a long time down a rabbit hole. When she finally lands, she finds herself in a strange world. In this strange world are some of the most popular characters in children's books. Many of the expressions from the book have found their way into American English.

    The first character Alice meets is the White Rabbit. The White Rabbit is not a usual rabbit. Alice chases (追赶) after him, and that is where her adventures begin.

    In English, "chasing a white rabbit" means to chase an impossible dream. "Following the white rabbit" means you are in the middle of an unusual situation. This situation often challenges your thinking and changes your life. Like "chasing a white rabbit", "falling down the rabbit hole" means we get interested in something else and lose ideas about time.

    Later in the story, Alice is the guest at a tea party— a crazy tea party! There she meets the March Hare. The hare seems to be truly crazy. To be "mad as a March hare" means that someone is completely mad or crazy.

Using expressions from popular books can add special flavor(味道). And when used properly, they also show you have a deeper understanding of the English language.

    Roger, a young man from China, has taught Chinese in a primary school in England for 3 years. A lot of children like his class and he enjoys teaching them very much. All the pupils are quite interested in what Roger teaches them. They learn quickly and do everything carefully.

    One day he said to the children, “People in a lot of Asian countries wear white clothes at funerals (葬礼), but people in America and in Europe wear white in the weddings because white means purity and happiness. What colour does an English woman wear when she gets married?”

    Mary said, “White, sir, because she is happy.” “That is good, Mary,” Roger said. “You are quite right. She wears white because she is happy.”

    But then one boy in the class put up his hand. “Yes, Dick?” Roger said, “Do you have a question?” “Yes,” Dick said. “Why do men wear black in our country when they get married, sir?”

(Renee—a beautiful princess   Broo—a blue bear   Nahloo—a magical place)

    When the Princess Renee heard about Broo, she came down from her astle. She found Broo while he was busy eating honey.

    "Mr. Bear," the Princess said, "you are welcome in Nahloo. Here we share with each other. We don't take things from each other."

    Broo thought about it for a moment and knew that he had made a mistake. "Well," he said, "maybe drinking all that milk wasn't the best idea."

    The Princess went on, "Mr. Bear you can drink and eat but you won't feel good because you have never made any contribution(贡献)to anyone else. I think you'll find that it is better to be full in your heart not just in your stomach." After saying this the Princess went back to the castle leaving Broo alone.

    One day Broo was going to take lots of cookies from the rabbits, and then he remembered what the Princess said to him. So Broo decided not to eat the cookies. The rabbits were surprised and said "Thank you for your kindness, Mr. Bear. Now these cookies will taste sweeter because they are given by you, my friend. If you like, come back tomorrow and we can have the cookies together."

    Broo was filled with joy and went through the land. He gave back everything he had taken. In return, he received a promise(承诺)from everyone to share their food with him. Broo was so glad that he started dancing in the moonlight with the Princess as his partner.

    Mrs Green isn't happy. Then she says, "That's dishonest."
