    There will be three kids movies in theaters. Let's know the main idea of them first.

    "How are you?" is a nice question. It's a friendly way that people in the United States greet each other, but "How are you?" is also a very unusual question. It's a question that often doesn't have an answer. The person who asks "How are you?" hopes to hear the answer "Fine", even if the Derson's friend isn't fine. The reason is that "How are you?" isn't really a question and "Fine", isn't really an answer. They are simply other ways of saying "Hello!" or "Hi!".

    Sometimes, people also don't say exactly what they mean. For example, when someone asks "Do you agree?". the other person might be thinking, "No, I disagree. I think you're wrong. "But it isn't very polite to disagree so strongly, so the other person might say "I'm not  so sure. "It's a nicer way to say that you don't agree with someone.

    People also don't say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person says "I have to go now. "Often, the person who wants to hang up gives an excuse: "Someone's at the door." "Something is burning on the stove. "The excuse might be real, or it might not. Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't polite to say that. The excuse is more polite, and it doesn't hurt the other person.

    Whether they are greeting each other, talking about an idea, or finishing a talk, people often don't say exactly what they are thinking. It's an important way that people try to be nice to each other, and it's part of the game of language.

    For many young people, Halloween is the best day of the year.

    Halloween comes on October 31^st. When it comes, all the family members always get together to make a pumpkin lantern. They usually cut scary(恐怖的) or funny faces into pumpkins. Then they put candles inside to make the pumpkins into lanterns.

    Children dress up in costumes. They walk around their neighborhoods to collect candies. They knock on their neighbors' doors. When a person opens the door, the children shout, "Trick or treat!" If the person gives them candies, they go away. If they can't get the candy, they always play tricks on the person.

    Many people have Halloween parties. They like to watch scary movies and tell ghost stories.

    "Cool" is a word with many meanings. Its old meaning is used to express a temperature that is a little cold. When the word is changing, the word has different meanings.

    "Cool" can be used to express feelings of interest in almost anything.

When you see a famous car in the street, maybe you will say, "It's cool." You may think "He's so cool" when you see your favorite footballer.

    We all maximize(扩大)the meaning of "cool". You can use it instead of many words such as "new" or "surprising". Here's an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall they visited last week. On one student's paper was just the one sentence, "It's cool." Maybe he thought it was the best way to show what he saw and felt.

    But the story also shows a scarcity(缺乏) of words. Without "cool", some people have no words to show the same meaning. So it is quite important to keep some credibility(可信性).Can you think of many other words that make your life as colorful as the word "cool" can? And I think they are also very cool.
