2. (2019高一下·株洲期末) 阅读明白     It was dinner time for the Rangers, a group of mostly Indigenous (内陆的) Australians who had spent a long day cleaning up the polluted beaches of the continent's northern coast. Soon they would be eating freshly caught fish and seafood cooked under the stars on an open fire, as their ancestors did.     The Rangers are of more than 100 Indigenous groups spread across Australia who have taken on the job of protecting the land of their forefathers. In Arnhem Land, they are the protectors of 3,300 square miles of land and sea. They comb the beaches by hand, picking up as much rubbish as possible. The task is very difficult as each day it delivers waves of new rubbish.     For the Rangers, cleaning the beaches is more than a vacation. For a people whose culture is strongly tied to the land, protecting the environment is equal to preserving their history.     However, colonization forcefully broke their connection to the land generations ago. Indigenous people were displaced and their cultural practices outlawed. Tens of thousands of years of traditional land management ended, and as a result many parts of the country now face serious disasters from invasive plant and animal species, bush fires and land mismanagement.     In recent years, the government has restored more than 20 percent of Australia's land to Indigenous owners. Since 2007, the Indigenous Rangers Organizations have been at work protecting this land.     Luck, one of the few non-Indigenous employees working with the Rangers, said the combination of old and new techniques and an appreciation for the culture of Indigenous workers has been critical to the program's success.     "You are working with staff who see the world different to you, so there is a much higher focus on the cultural aspects of work and life," he said.     "Being a ranger is a source of confidence. You feel strong," said Terence, a senior ranger. "Here we still live on the land. The culture is still alive."3. (2019高一下·浙江开学考) 阅读明白     We bet that on cold winter days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of small insects like to do the same thing! Winter is the time when small insects enter your house without an invitation. The season can be difficult for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So small insects do what they have to do to survive.     Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapauses. There're different kinds of diapauses, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn't when the temperature drops.     They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there's each day. They use that to tell themselves when to shut down. Insects are cold-blooded, meaning that their inside temperature is the same as the outside. They can't move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.     They're looking for protection. These guys have been doing this for 300 million years, so they don't really know they're coming into your house. The home is a recent event in terms of their evolutionary (进化的) behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be entering your homes for warmth and food, but they don't care about humans.
