Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it.

Water can change from a solid to a liquid or to a gas easily. This is why we always have fresh water. Now let us find out how it does. The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air.

When the clouds come near a mountain, they rise high. As the clouds rise, they get cooler. The higher they rise, the cooler they become. Then more and more water gas turn into water drops. In this way, the drops of water in the clouds get bigger and bigger. Then they fall to the earth as rain.

A long story about people is usually called a novel. It can be about any kind of man, woman, or child. It can be about kings, or Chicago newsboys, or housewives. The French writer, Victor Hugo, wrote his novel Les Miserables about a poor man who stole (偷) a loaf of bread. The American writer, Ernest Hemingway, wrote A Farewell to Arms about a young American with the Italian Army in World War One.

A novel can tell the story of any kind of action, over any period of time. The modern Irish writer, James, Joyce, covers less than twenty-four hours in Ulysses. Yet, Joyce takes a thousand pages to tell all that happens from the time one man gets up in the morning until he goes to bed early the next morning. A German writer, Herman Hesse, uses only one hundred and fifty pages in his novel Demian to cover a boy’s life from the age of ten until he becomes a young man.

A novel does not just tell the things that people do. It also tells why they do them. The Badge of Courage, by the American novelist, Stephen Crane, tells about a young soldier who runs away the first time he is in the war. The book shows why he acted as he did. It describes his mental suffering (精神折磨) until he overcomes his fears.

People buy novels because they enjoy reading about other people. The novel meets the human desire (欲望) to know and understand other people.

Traveling by train is usually not easy in China. It can be hard to get a ticket. When you’re traveling to the railway station you look at your watch, afraid you will miss your train.

But there is good news for people traveling between Beijing and Shanghai. Construcion(建设) on the express railway(高速铁路) between the two cities started just before the Spring Festival of 2008. When it is finished by 2013, taking a train will be as easy as taking a bus.

The new line will be 1,318 kilometers long and go across specially built bridges. It will run alongside the present line. There will be 21 stations, in Hebei, Tianjin, Shandong, Anhui and Jiangsu.

“The cost of traveling by the express railway may be around 800 yuan. That will be more expensive than an ordinary train. But cheaper than by air,”said Zhang Xiaolin, a Jiangsu government official.
