24.The earliest process of making paper was done almost five thousand years ago in Egypt and the Nile Valley. In those days, paper was made from strips of the papyrus plant. Modern paper-making began in China about two thousand years ago. This process produced paper from cloth, straw, wood or the bark of trees. The raw materials are struck over and over until they become loose. Then they are mixed with water. After the water has been removed, the flat, thin form remaining is permitted to dry. This becomes a sheet of paper.Large machines started to be used for making paper near the end of the sixteenth century. Today, paper-making is a big business. But it is still possible to make paper by hand, since the steps are the same as using big machines.You should choose paper with small amounts of printing. Old envelopes are good for this reason. Colored paper also can be used, as well as small amounts of newspaper. Small pieces of rags or cloth can be added. These should be cut into pieces about five centimeters by five centimeters.Everything is placed in a container, covered with water and brought to a boil. It is mixed for about two hours with some common chemicals and then allowed to cool. Then it is left until most of the water dries up. The substance left, called pulp, can be stored until you are ready to make paper.When you are ready, the pulp is mixed with water again. Then the pulp is poured into a mold. The mold is made of small squares of wire that hold the shape and thickness of the paper. To help dry the paper, the mold lets the water flow through the small wire squares.After several more drying steps, the paper is carefully lifted back from the mold. It is now strong enough to be touched. The paper is smoothed and pressed to remove trapped air. You can use a common electric iron used for pressing clothes.(10分)24.1 According to this passage, the earliest paper was made by ______.(2分)A. Chinese peopleB. Roman peopleC. Indian peopleD. Egyptian people
22. Urban growth, also known as urbanization (城市化)，sped up dramatically with the coming of industrialization some 200 years ago. At that time, large numbers of people moved to cities in search of jobs, mostly in factories. But the most rapid growth has taken place over the past 50 years. While less than one-third of the world’s population lived in cities in 1950, about two thirds of humanity is expected to live in urban areas by 2030.Urban is defined as “that which is characteristic of a city.” But what exactly is a city? In the past, walls may have defined a city. But today’s city boundaries are often unclear. Are suburbs parts of cities? Depending on the boundaries used, Tokyo can have a population of anywhere between 8 and 40 million people.Cities make a lot of sense for humans. People are concentrated in a small space rather than being spread out over a large territory. This allows the government and others to provide more service such as water, electricity, and transportation to a larger number of people. Schools and shops are more easily accessible than in rural areas.Cities have always been at the center of economic growth and technological advances. The promise of jobs and prosperity pulls people to cities. But their rapid growth has also brought with it many negative things: violence, poverty, overcrowding, health problems, and pollution. Many cities in developing countries in particular are growing too rapidly for their own good, with many residents unable to find jobs and forced to live in slums.(10分)22.1 About years ago, people left for cities to find .(2分)A. foodB. clothesC. jobs D. factories

22. Chess must be one of the oldest games in the world. An Arab traveler in India in the year 900 wrote that it was played "long, long ago". Chess was probably invented in India, and it has been played everywhere from Japan to Europe since 1400. The name "chess" is interesting. When one player is attacking the other's king, he says, in English,"check". When the king has been caught and cannot move anywhere, he says "check mate". These words come from Persian. "Shah mat" means "the king is dead". That is when the game is over, and one player has won.Such an old game changes very slowly. The rules have not always been the same as they are now. For example, at one time the queen could only move one square at a time. Now she is the strongest piece on the board. It would be interesting to know why this has happened! Chess takes time and thought, but it is game for all kinds of people. You don't have to be a champion in order to enjoy it. It is not always played by two people sitting at the same table. The first time the Americans beat the Russians was in a match played by radio. Some of the chess masters are able to play many people at the same time. The record was when one man played 400 games! It is said that some people play chess by post. This must make chess the slowest game in the world.(10分)22.1 Which of the following is known to be true?____(2分)A. Chess is an old Indian traveling game.B. Chess is the oldest game in the world.C. Chess was played in Japan and Europe before 1400.D. Chess was played in India long before 900.
