[素能提升练]Ⅰ.阅读理解(每小题2.5分,共10分)(2025·南京市高一检测)Urban expansion (城市扩张) has greatly changed the habitats of many animals.Forests are cut down to build houses,rivers are changed to provide water for big cities,and pollution is now a serious problem for many ecosystems.These actions force animals to get used to city life,often causing conflicts when they enter areas where people live to find food or a place to stay.Environmentalists say that it’s important to create special places called wildlife reserves.These reserves protect animals that are in danger and help keep different kinds of life in nature.Wildlife reserves are like safe homes where animals and plants can live and grow without being bothered by people.Studies show that animals in these protected areas survive better,which helps maintain balance in nature.Every animal,from small insects to large animals,plays an important role in keeping the ecosystem healthy.In addition to reserves,people are also working on setting up “wildlife corridors”.These are protected paths between places animals live in,which allow animals to migrate safely.Without such corridors,animal groups that live alone in one place lose genetic diversity (基因多样性),which makes them more likely to die out.For instance,large predators like tigers and wolves need big space to hunt and survive.Corridors offer these animals freedom to move around without entering human spaces.Protecting biodiversity (生物多样性) not only benefits animals but also supports human life.Healthy ecosystems control water flow,clean the air,and stop the climate change,all of which are extremely important for human survival.Therefore,protection efforts not only focus on saving different species,but also make sure our environment stays healthy for everyone.【语篇解读】 本文是一篇说明文。文章主要介绍了城市扩张对野生动物栖息地的影响,以及建立野生动物保护区和野生动物走廊对于保护动物和生态系统的重要性。1.What is one main result of urban expansion on wildlife A.Fewer people in cities.B.Fewer human activities.C.Damage to animal habitats.D.More places for animals to live.答案 C [细节理解题。根据第一段中“Urban expansion (城市扩张) has greatly changed the habitats of many animals.”可知,城市扩张对野生动物的一个主要后果是破坏了动物的栖息地,故选C项。]2.What is the purpose of wildlife reserves A.To attract more tourists.B.To create jobs for local people.C.To protect animals from human bothering them.D.To allow humans to connect with animals.答案 C [细节理解题。根据第二段中“These reserves protect animals...without being bothered by people.”可知,建立野生动物保护区的目的是保护动物不受人类的干扰,故选C项。]3.What is the author’s attitude toward creating wildlife reserves and corridors A.Supportive.
