Volcanoes can be fun to learn about. It can be neat to watch them erupt. But if you live near a volcano, you know that they are dangerous! An eruption can like an explosion. Rock and lava can throw up into the air. Streams of red hot lava quickly run down from the peak of the volcano. The air is filled with deadly gases. These things can put many lives in danger. Scientists have learned that there are many things that they can study to help them tell when an eruption might happen. They can study the movements of the ground. When a volcano is about to erupt, the ground will often move just like it does during an earthquake. Scientists can also measure the gases that come out of a volcano. Most volcanoes emit gases all of the time. More gases are let out as the volcano gets closer to erupting. They can also study the way the land and water around the volcano. Scientists can read these signs and warn people of danger. They may not realize it, but their work helps to keep people safe! 26. In the passage, a volcanic eruption is compared as .

Bands of thunderstorms form and swirl around and around because the rotation of the earth. As more and more thunderstorms form, the hurricane gets bigger and bigger. A hurricane is one of the world's worst storms because it can last for days or weeks. Hurricanes can also be very large. They may cover hundreds of miles and affect large areas of land. For a storm to be classified as a hurricane, wind speeds within the storm have to reach at least 74 per hour. But hurricane winds can reach speeds of over 155 miles per hour! A large amount of destruction may occur with winds that strong. Roofs may be torn off homes. Buildings may be flattened. Trees topple over. Hurricanes are deadly, but not just because of their winds. They can also produce very heavy rains and huge waves that slam into the coastline. Hurricanes are very common along the east coast of the United States. Here, wind, waves, and rain do the most damage. Luckily, meteorologists (people who study weather) can forecast hurricanes days in advance by using radar technology. Radar is a little bit like a moving picture. It shows how big storms are and which way they are moving. Radar images people time to prepare for a coming storm. If the storm is very strong, home and business owners will put up plywood to protect their glass windows and doors. People who live along the coast will evacuate. They'll go to a hurricane shelter or stay with friends and relatives who live in safer places farther inland. Many lives are saved every year by people who take the necessary precautions. 31.

It comes from household chemicals; the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things. First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it. Second, we need to watch the amount of water used in the home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth. Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing. If we do our part in our own homes, we can help keep the planet from becoming more polluted. 36. Pollution can be caused from the following sources except .

They are not just a single group of people - there are many different tribes of Native Americans. Different Native American groups have different languages, religious believes, and ways of living, or folkways. The Hopi are Native Americans who come from what is now the American Southwest. When the Spanish came to America in the 16th century and found the Hopi people, they nicknamed them “pueblo people” because Hopi people didn’t move around much - they lived together in what amounted to towns. Pueblo is a Spanish word that means “town.” The Hopi have always been a very peaceful people. Their name comes from the term Hopituh Shi-numu, which means, in the Hopi language, “The Peaceful People” or “Peaceful Little Ones.” The Navajo come from the same general area as the Hopi. But instead of staying in one place, they moved around. They didn’t live in permanent towns like the Hopi. They were a “semi-nomadic” people. While the Hopi were historically known for farming, the Navajo were known for hunting and gathering. After they met the Spanish, the Navajo became known for herding sheep. The Hopi, not so much. Today, there may not be as many thriving Native American tribes as there used to be, but there are more than a few. All in all, there are about 1,000 different groups of Native American people in the United States, and each group is unique. 41. How long have Native Americans been living in America? A.

Which of the following is NOT true about the Hopi? A. They live in the American Southwest. B. They were farmers. C. They travelled from place to place in search of land. D. They enjoyed a peaceful way of life. 44. What does the word “permanent” most nearly mean? A. changing B. cultural C. long-lasting D. unstable 45. After the Spanish arrived in the 1600s, the Navajo A. didn’t live in permanent towns. B. lived by hunting and gathering. C. moved from their homeland. D. began to farm sheep.
