Passage 2:

Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing material more than 5000 years ago. The Chinese invented the paper that we use 2000 years ago.

             A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resin may add weight and texture.

            Where do these fibers come from ? The majority of paper is made from the plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may also be made from things like old rags or pieces of cloth. Wastepaper, paper that has been made and used, can be turned into recycled paper. This recycling process saves forest, energy and reduces air and water pollution.

Passage 4:

      Along with jogging and swimming, cycling is one of the best all-round forms of exercise. It can help to increase your strength and energy, giving you more efficient muscles and a stronger heart. But increasing your strength is not the only advantage of cycling. Because you’re not carrying the weight of your body on your feet, it’s a good form of exercise for people with painful feet or backs. However, with all forms of exercise it’s important to start slowly and build up gently. Doing too much too quickly can damage muscles that aren’t used to working. If you have any doubts about taking up cycling for health reasons, talk to your doctor and ask for his/her advice.

Passage 5:

Music influences people in different ways or the same person differ­ently at different times. Music may seem to influence people differently. That is because people can react differently to the music. We are able to apply a choosing process to the music we hear. If someone hates jazz, then a jazz piece with a positive effect will probably not make him feel good. A happy song might appear to make an angry person angrier, yet it is not the music itself that is creating the anger; rather it is the positive effect of the music. The angry person does not want to accept the song's happy feeling: it points out his already existing anger, and makes that anger come to the surface. When a piece of music is played and we are listening to it, our body, mind, and feelings are being affected. The musi­cians of ancient cultures such as China, India, Turkey and Greece under­stood the effects of music. In fact, Pathagoras, in ancient Greece, intro­duced a whole science that concerned them. Because the musicians of these ancient cultures understood these effects, they created music that was positive, uplifting, and beneficial. Once the effects of music are better understood, the next step is to gain a better understanding of the music around us, and what effect it is actually having.

Passage 7:

     Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so no new space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages. Wind and water power rely on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime.

      However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cells require large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil, and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy.

1. What does the passage primarily discuss?

A. Advantages and disadvantages of solar energy.

B. Solar energy’s advantages over other sources of energy.

C. The cost of solar energy.                                     

D. Solar energy as an alternative for fossil fuels.

C. advantages.                                                      D. solar cells.

3. What is NOT mentioned as an advantage of solar cells?

A. They require little maintenance.                B. They are non-polluting.

C. They cost little to produce.                          D. They operate quietly.

4. Which of the following is NOT a traditional source of energy?

Passage 8:

When you enter the supermarkets, you see shelves full of food. You walk in the aisles between the shelves. You push a shopping cart and put your food in it.

            You probably hear soft, slow music as you walk along the aisles. If you hear fast music, you walk quickly. The supermarket plays slow music, you walk slowly and have more time to buy things.

            Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.

            The dairy department sells milk and milk products such as butter and cheese. Many customers like milk that has only little butterfat in it. One store has three different containers of low fat milk. One says ‘1% fat’ on the container. The second says ‘99 percent (99%) fat free’. The third says ‘Low fat’ in big letters and 1% in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. The amount of milk in each container is also the same. However, in this store they cost three different amounts of money. Maybe the customers will buy the milk that costs the most.

1. What is the main topic of this passage?

          A. How different kinds of food are arranged in supermarkets.

          B. Soft, slow music makes people buy more in supermarkets.

          C. The supermarket is designed to make you buy things.

Passage 7:

     Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so no new space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages. Wind and water power rely on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime.

      However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cells require large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil, and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy.

Passage 8:

When you enter the supermarkets, you see shelves full of food. You walk in the aisles between the shelves. You push a shopping cart and put your food in it.

            You probably hear soft, slow music as you walk along the aisles. If you hear fast music, you walk quickly. The supermarket plays slow music, you walk slowly and have more time to buy things.

            Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.

            The dairy department sells milk and milk products such as butter and cheese. Many customers like milk that has only little butterfat in it. One store has three different containers of low fat milk. One says ‘1% fat’ on the container. The second says ‘99 percent (99%) fat free’. The third says ‘Low fat’ in big letters and 1% in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. The amount of milk in each container is also the same. However, in this store they cost three different amounts of money. Maybe the customers will buy the milk that costs the most.
