Passage 6
Living Space
How much living space does a person need? What happens when his space needs are not met? Scientists are doing experiments on rats to try to determine the effects of overcrowded conditions on man. Recent studies have shown that the behavior of rats is greatly affected by space. If rats have enough living space, they eat well, sleep well and produce their young well. But if their living conditions become too crowded, their behavior and even their health change obviously. They can not sleep and eat well, and signs of fear and worry become clear. The more crowded they are, the more they tend to bite each other and even kill each other. Thus, for rats, population and violence are directly related. Is this a natural law for human society as well? Is enough space not only satisfactory, but necessary for human survival? These are interesting questions.(147 words)
Passage 7
Private Cars
With the increase in the general standard of living, some ordinary Chinese families begin to afford a car. Yet opinions of the development of a private car vary from person to person.
It gives a much greater degree of comfort and mobility. The owner of a car is no longer forced to rely on public transport, and hence no irritation caused by waiting for buses or taxis. However, others strongly object to developing private cars. They maintain that as more and more cars are produced and run in the street, a large volume of poisonous gas will be given off, polluting the atmosphere and causing actual harm to the health of people.
Whether private cars should be developed in China is a difficult question to answer, yet the desire for the comfort and independence a private car can bring will not be eliminated.(143words)
Passage 8
Plastic
We use plastic wrap to protect our foods. We put our garbage in plastic bags or plastic cans. We sit on plastic chairs, play with plastic toys, drink from plastic cups, and wash our hair with shampoo from plastic bottles!
Plastic doesn’t grow in nature. It is made by mixing certain things together. We call it a produced or manufactured material. Plastic was first made in the 1860s from plants, such as wood and cotton. That plastic was soft and burned easily.
The first modern plastics were made in 1930s. Most clear plastic starts out as thick, black oil. That plastic coating inside a pan begins as natural gas.
Over the years, hundreds of different plastics have been developed. Some are hard and strong. Some are soft and bendable. Some are clear. Some are many-colored. There is a plastic for almost every need. Scientists continue to experiment with plastics. They hope to find even ways to use them! (160 words)
Passage 9
Display of Goods
Are supermarkets designed to persuade us to buy more?
Fresh fruit and vegetables are displayed near supermarket entrances. This gives the impression that only healthy food is sold in the shop. Basic foods that everyone buys, like sugar and tea, are not put near each other. They are kept in different aisles so customers are taken past other attractive foods before they find what they want. In this way, shoppers are encouraged to buy products that they do not really need.
Sweets are often placed at children’s eye level at the checkout. While parents are waiting to pay, children reach for the sweets and put them in the trolley.
More is bought from a fifteen-foot display of one type of product than from a ten-foot one. Customers also buy more when shelves are full than when they are a half empty. They do not like to buy from shelves with few products on them because they feel there is something wrong with those products that are there. (166 words)
Passage 10
Albert Einstein
Albert Einstein was born in Germany in 1879. His father owned a factory that made electrical devices. His mother enjoyed music and books. His parents were Jewish but they did not observe many of the religion’s rules. Albert was a quiet child who spent much of his time alone. He was slow to talk and had difficulty learning to read. When Albert was five years old, his father gave him a compass. The child was filled with wonder when he discovered that the compass needle always pointed in the same direction—to the north. He asked his father and his uncle what caused the needle to move. Their answers about magnetism and gravity were difficult for the boy to understand. Yet he spent a lot of time thinking about them. He said later that he felt something hidden had to be behind things. (143 words.)
