V. Read this passage about the effects of visual pollution.

Visual pollution has a greater effect on people than you may think. I remember when I went to a foreign city, I was really scared because there was so much graffiti on the buildings' walls. Then I looked up, and I saw a lot of power lines over my head. Although they were not dangerous, I still felt insecure since I thought they might fall down. These things prevented me from enjoying the beautiful sights of the city. I also remember the time I studied in Melbourne. Once I was so busy with my assignments that I did not tidy my room for two weeks. Looking at the messy room caused me so much stress that I did not want to study. Then I decided to clean the room and put my things in their proper places. I also bought a small plant and placed it in a corner. These simple actions increased my motivation and helped me focus on my learning.What about you? Have you ever been affected by visual pollution?

Answer the questions.1. Why was the author scared when she was in a foreign city?        2. How did the author feel when she saw the power lines?3. Why did she have that feeling?4. What was she busy with?5. What happened when she looked at the messy room?6. What did she do for her room?

VI. Circle the correct answer A, B, or C.

Noise is constant and loud sound. To measure the loudness, or volume of sounds, people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or a motorcycle can result in permanent hearing loss after eight hours? The sounds of a concert are even more serious. They can reach as high as 130 decibels and may cause immediate and permanent hearing loss. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music through headphones, and other people can hear it, it means the music is too loud and unsafe. If there seems to be a ringing or buzzing in your ears, it means the noise is affecting you and damaging your hearing. Wearing earplugs when you go to concerts or other loud events, and listening to music through headphones or headsets at safe levels can help you reduce the effects of noise pollution.
