单元加餐练Ⅰ.阅读理解AMandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington DC.And on Tuesday, August 23rd, witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.“It's very different from their normal call，” said Brandie Smith, the zookeeper. “The lemurs (monkey-like animals of Madagascar) will sound an alarm if they see or hear something highly unusual.”But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can—if you're an animal. “Animals can hear above and below our range of hearing，”said Brandie Smith. “That's part of their special abilities. They're more sensitive to the environment, which is how they survive.”Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of birds) gathered before the quake and stayed together until the shaking stopped.So what kind of vibrations (震动) were the animals picking up in the moments before the quake? Scientist Susan Hough said earthquakes produce two types of waves—a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She thinks the “P” wave might be what sets the animals off.Not all the animals behaved unusually before the quake. Forexample, Smith said the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I'm not surprised at all，”Smith said.篇章导读：本文是一篇说明文。

单元加餐练Ⅰ.阅读理解AThis summer, I was part of something that I have carried with me every day since. An experience changed my life. The Kentucky YMCA has a program called Y－Corps, which are service trips of around 20 students. This summer, two trips were made across Kentucky, one down south and the other trip up north.I was on the Y－Corps Service to the North in Indianapolis, Indiana, and our trip began at the end of July. I had butterflies flying around me as my parents drove me to Louisville, where the Service to the North team would set off on a nine－day journey in a school bus. I knew some of the team members from previous Y－Conferences, but there were many that I had never met, and I had never participated in a service trip like this before. Though I was nervous, I was also ready to try something completely out of my comfort zone. Once we loaded the bus with our lightly packed suitcases and sleeping bags, we said our goodbyes to our parents and departed for an adventure that changed all of our lives.Wi th the Kentucky Y's motto: “Participate, don't anticipate”，we had no idea where we were headed. Road signs were our only clue of where we would be stopping. We did service work at a Middle Way House in Indiana, a Detroit Market Garden, a Pennsylvania YMCA for an invasive (侵略性的) species clean－up, the Upper Main Line Y in Pennsylvania to spend time with children at a summer camp, a Hurricane Sandy clean－up in Jersey Shore and the National Mall in Washington DC. We slept on floors of local YMCAs that would take us in for a night, and some nights we didn't have the opportunity to shower. We had late nights on the road driving from city to city, and early mornings to start the day journaling and reflecting on the day before.Though we were physically tired from the hard work, we still enjoyed the time to experience the culture of the areas we were in.篇章导读：本文是一篇记叙文，主要讲述了作者参加去美国北部城市印第安纳波利斯的义务服务旅行的情况，作者认为此次行程虽然辛苦却很有意义，令人难忘。

单元加餐练Ⅰ.阅读理解AThe “happiest place on earth” is a top destination on many families' bucket lists (人生目标清单). But taking a vacation to Disney World can be difficult to do on a budget. There are some considerations that you can make to reduce the cost of your Disney World vacation.1．Come PreparedPlan ahead so that you don't have to purchase a necessity at Disneyland that you could have brought from home. For example, check the weather so that you don't need to buy a raincoat or an umbrella.2．Buy Souvenirs in AdvanceDisney has influenced practically every industry, which makes it easy to find Disney items anywhere, from Walmart, Target, and your local grocery stores to department stores and Amazon. You can save a lot of money by purchasing items before your trip at these less expensive places than at Disneyland.3．Make an Autograph BookAn autograph book is seen as a must-have by many Disneyland enthusiasts and is a memory you can take home with you. These books can cost anywhere from 7.95 to 19.95 at the Disney Store and up to $30 for the latest-and-greatest autograph book at Disneyland, such as the park's 60th anniversary editions. Other choices can get the job done for under $5. For example, you can buy a small photo album, cute pads or notebooks.4．Take Advantage of Discounts Offered to Special GroupsDisney offers a wide variety of discounts, including military service members, college students, teachers, and youth groups. If you think you might qualify for a special discount or group rate, call the Disneyland Resort to book tickets.篇章导读：本文是一篇应用文。

单元加餐练Ⅰ.阅读理解AThe British live on a small island. They are surrounded by the sea, so it is not surprising that the sea has always played an important role in their lives. After the development of large, ocean-going sailing ships in the fifteenth century,the sea became even more important to the country's development. Ships setting sail from England determined to extend Britain's territories, its wealth and its knowledge of the world. Ships returned to England bringing goods, people and new ideas from foreign places. By the nineteenth century, Britain had the largest, most powerful navy in the world.The great sailing ships were so much a part of British life that they even affected the language. Many English expressions we use today were originally nautical (航海的)terms,although most people no longer realize this. For example, people commonly describe an honest and fair business deal as being “above board”.This expression was originally used in sailing ship times when secretive, dishonest ship's business would be carried out below decks ( i.e. below the boards) out of public view. On the other hand, honest business was always conducted on deck (above the boards), in the open where everyone could see what was going on.“Pipe down！”，meaning “Be quiet！”，is another common expression that has nautical origins. The ship's boatswain (水手长)would blowa whistle,or pipe, at the end of the day to indicate (表明)to the sailors it was time to quieten down and go to sleep.Most native English speakers have heard the expression “not enough room to swing a cat”，but few know that the “cat” does not refer to a small furry animal with four legs and a tail.The “cat”is actually a short form of “cat of nine tails”—a whip with nine, knotted(打结的) tails.A boatswain needed a lot of space in order to swing the whip properly when lashing (鞭打)a poor sailorunder hiscontrol!篇章导读：本文是一篇说明文。

单元加餐练Ⅰ.阅读理解AJust in time for National Popcorn Day, a new study shows that people in what's now Peru were eating the snack about 2,000 years earlier than we thought.Coastal peoples were preparing corn－based foods up to 6,700 years ago, according to analysis of remains of the ancient corn recently discovered at the Paredones and Huaca Prieta archaeological sites on Peru's northern coast.Previously, evidence of corn as a food about 5,000 years ago had mostly come from what are called microfossils—microscopic remains that do not offer information on the size and shape of the corncobs (玉米棒). But the newly found corn remains revealed a lot, via radiocarbon dating and other tests.The people who lived in Paredones and Huaca Prieta probably cooked corn in several ways: Wrapping a corncob and resting it on coals, roasting a corncob directly over a flame, or cooking a corncob in an earthen oven. In this culture, corn was a delicious food or a minor supplement to the diet-archaeological evidence shows they did not eat it in large amounts.Corn was first grown in Mexico about 9,000 years ago from a wild grass called teosinte, according to Piperno, whose research has been published in the journal Proceedings of the National Academy of Sciences. A few thousand years later, corn was brought to South America, where farmers bred the plant crop into hundreds of varieties.Indeed, what surprised Piperno most about the new research was the diversity of corn—from corncob shapes to kernel (玉米粒) colors discovered in the new-found remains. “Farmers like to experiment and grow cool things，” she said.篇章导读：本文是一篇说明文。

单元加餐练Ⅰ.阅读理解AGetting close to active or erupting volcanoes can be dangerous. But for Michael Rampino, it's all in a day's work. Rampino is a volcanologist, a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows (熔岩流) in Hawaii and explosive volcanoes in Indonesia. He knows when to get close to an active volcano and when to back away.Rampino wasn't always a volcanologist. He worked for NASA for seven years. He studied rocks until he began to research climate change and the effects that volcanoes have on climate. He became interested in the subject. “Once I started working with volcanoes，” Rampino said, “I was hooked.”Rampino is a professor at New York University. As part of his job, he travels to areas where volcanoes have been active. “Active” means they have erupted within the past few centuries and probably will erupt again. Rampino studies the deposits (沉积物) of ash and other materials from the eruptions. The ash may hold clues to what happened to the Earth in the distant past. It may also help scientists predict what could happen to Earth's climate in the future.Rampino doesn't work alone. He works with a team of scientists who use computers to stimulate (模拟) the effects volcanoes have on Earth'satmosphere.Being a volcanologist may be hard work, but it's also fun. “It's cool traveling the world studying volcanoes，” Rampino says. When he talks to students about his work, he tells them that his goal is “to understand the events that have shaped Earth's history.”篇章导读：本文是一篇记叙文。
