Many expressions that we use in American English come from novels. Today we will look at some of them from Lewis Carroll's famous novel "Alice in Wonderland" in detail.

    The story is about a young girl falling down a rabbit hole. When she finally lands, she finds herself in a strange world and meets some strange characters.

    The first character Alice meets is the White Rabbit, who runs past her and says some strange words. Alice chases（追赶）him, and that is where her adventures begin.

    In English, chasing a white rabbit means chasing an impossible clue and finding yourself in a misleading situation.

    Then, as she runs after the rabbit, she falls down the rabbit hole into Wonderland.

    To fall down the rabbit hole can mean to enter a confusing（令人困惑的）situation. However, usually we use this expression to mean we get interested in something to the point of distraction（分神）.It often happens by accident and is about something not that meaningful.

    Later in the story, Alice meets the March Hare and the Hatter at a crazy tea party. Hares（野兔）have long been thought to behave excitedly in March, which is their mating（交配）season. Scientifically, this may not be true. But to be mad as a March Hare means that someone is completely mad, or crazy. The expression mad as a Hatter also means to be completely crazy. Of the two, mad as a Hatter is more common. But don't tell the March Hare. Who knows how he will react（反应）！

    Near the end of the story, Alice meets the Queen of Hearts. A woman who is called a Queen of Hearts likes controlling others and always tries to control everything and everyone around her.

    Ancient China produced many types of beautiful works of art. Among them，calligraphy(书法)，poetry(诗歌)and painting were the most famous. Often they would be put together in art. These became important starting with the Song dynasty.

Calligraphy is the art of handwriting. In the old times the Chinese considered writing as an important form of art. Calligraphers(书法家)would practice for years to learn to write perfectly，but with style. Each of over 40,000 characters needed to be written correctly. And each stroke(笔画)in a character had to be written in a certain order.

Poetry was also an important form of art. Great poets were famous all over the country，but all educated people were expected to write poetry. During the Tang dynasty poetry was so important that writing poetry was part of the examinations to become a civil servant (文官)and work for the government.

    Chinese painting was often connected with calligraphy. It is one of the oldest artistic traditions in the world. The most traditional way of Chinese painting is known as "national "or" native painting(国画)", which is quite different from Western painting. People can draw mountains, homes, birds, trees and water on it.

    In a map of the world you can easily find two big cities, London and New York. London is the biggest city in Europe. New York is the biggest city in America. The streets in London are crowded and there is one of the world's biggest underground railway systems(地铁系统) .The streets in New York are just as crowded as those in London. And the New York subway carries more people each day than the London underground. There are a lot of big stores in these two cities. But New York has more supermarkets than London.

    In London there are many palaces(宫殿) and churches, for example, St. Paul's. New York isn't as old as London, and it hasn't got many old buildings. But its skyscrapers(摩天大楼) are much bigger than the buildings in London.

    London has more parks than New York, But New York's Central Park is much bigger than the biggest park in London.

    When you write a text message or an email, you might put a smiling face or other pictures at the end to make the message more fun. These pictures are emojis. The first emojis were on Japanese mobile phones in the 1990s. Later, they were used on Apple's iPhone and Android phones. Now they are everywhere!

Before emojis, there were emoticons. The word is a mixture(混合) of emotion(感情) and icon(图标). Emoticons are made of the signs you can find on your keyboard, for example:) for a smiley or @};—for a rose. The first use of :-)was in 1982 and it was called "joke marker". Emoji is a Japanese word which means pictograph: e(picture) +moji (character). Emojis are real pictures, for example ，or . There are 1851emojis that can be used on mobile phones and other devices. There are all kinds of emojis, from faces and weather to things in the kitchen and animal.

    In England, we have a saying: A picture paints a thousand words. For many people, an emoji is like a punctuation mark(标点). It's like the tone of voice when we speak on the phone, or hand movements(gestures) used in conversation. Emojis are also changing the way we write. The more we use emojis, the less we use slang(俚语), such as LOL or OMG.

    When someone speaks and looks serious, we try to look serious, too, and when someone smiles, we smile as well. This is how we show empathy(同感) and make friends(and enemies!). But when we're online, we can't see the person's face and there's no emotion. The invention of emojis changed that! Scientists in Australia have discovered that when we look at a smiley face online, the same parts of the brain start working as when we look at a real smiley face. Our mood changes, and we try to change our face to match the emoji. This is something we learn as we get older. Our brains have developed this ability over the last two or three years. This means that emojis have created a new brain pattern(模式)in us!
