The earliest process of making paper was done almost 5,000 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 2,000 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 16th 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 5 centimeters by 5 centimeters.
Everything is placed in a container, covered with water, and brought to a boil. It is mixed for about 2 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 special box or 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.
When the paper is lifted from the mold, it is time to _____.
选项
A、make it smooth
B、make it strong
C、decorate it
D、iron it
答案
A
解析
最后两段是手工造纸的最后两个步骤,最后一段是最后一个步骤,表明把纸从模子中取出后,应该把纸压平,去除残留的空气,A与原文的The paper is smoothed同义,为本题答案。本题较具干扰性的是B和D。B用了倒数第2段末尾的strong一词,倒数第2段表明把纸从模子中取出时,纸已变得相当坚韧了,因此,B不符合造纸步骤的先后顺序;D用了最后一段最后一句的iron一词作干扰,但用普通电熨斗只是把纸压平的一个办法,原文未表明这是一定得用的方法,因此,D也不对。
