题型组合练(二十九)　选择性必修第二册　Unit 5　A delicate world (建议用时：45分钟　总分：47.5分) Ⅰ．阅读理解(共8小题；每小题2.5分，满分20分) A (2025·黑龙江大庆二模)Since wolves was put on the Endangered Species List，the predators (捕食者) have slowly returned to more of their habitats． But in every place where wolves recovered，heated debates followed—about their numbers，hunting and trapping rights． However，Minnesota is an exception． Some of the techniques used by Minnesotans to avoid conflicts may need to be adopted in other states if the predators continue to return． 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world Minnesota is the only place in the United States to never kill all its wolves．More than 2，700 wolves live in Minnesota． The wolf population in Minnesota has been remarkably stable，bouncing between 2，400 and 3，000． That's well above the original recovery goal of 1，400． The relatively fixed population shows that wolves have likely already spread to every part of the state that has enough food to support them and is far enough from men． 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world Despite such high numbers，wolves attack cattle，turkeys and other animals on less than 2% of livestock (牲畜) operations in Minnesota． As wolf numbers have remained stable for nearly three decades，so have those conflicts． Farm owners have had mixed results using various methods to scare wolves away． The most adopted method comes from a farm on the border of Voyageurs National Park，where wolf researchers are building a 6-foot-high fence around the property． Early results show that wild wolves don't seem to try to jump fences for food． 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world However，there are still many unanswered questions． But most importantly to wildlife managers，exactly what does a healthy wolf population do for the ecosystem? To get the answer，researchers have come to Minnesota to learn about how wolves behave and survive． Now with GPS and tracking cameras，researchers are getting their first detailed look at how the secretive predators live all year round． 【语篇解读】　本文是一篇说明文。文章主要探讨了狼作为濒危物种受到保护后，如何在明尼苏达州数量保持稳定，以及人类与狼群和谐共存的方法。 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world √ 1．What can we learn about Minnesota? A．It never kills any of the wolves there． B．It provides ideal habitats for the wolves． C．It avoids disturbing normal wolf activities． D．It succeeds in handling human-wolf co-existence． D　[推理判断题。根据文章第一段中“Some of the techniques used by Minnesotans to avoid conflicts may need to be adopted in other states if the predators continue to return．”以及第二段第一句话可知，明尼苏达州在人狼共存问题上做得非常成功。因此，明尼苏达州成功解决了人类与狼的共存问题。故选D。] 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world √ 2．What does the stability of wolf population indicate? A．Wolves in Minnesota have adapted to the environment there． B．The Endangered Species List is effective and well carried out． C．The original recovery goal is too low and needs to be adjusted． D．Wolves are widely distributed and distant from human society． A　[推理判断题。根据第二段中“The relatively fixed population shows that wolves have likely already spread to every part of the state that has enough food to support them and is far enough from men．”可知，狼群的数量稳定表明它们已适应环境，在合适的地方生活得很好。由此可推知，狼群已适应了明尼苏达州的环境。故选A。] 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world √ 3．What does the author think of building fences? A．Traditional．　 B．Rewarding． C．Economical．　 D．Thoughtful． B　[推理判断题。根据文章第三段中“Early results show that wild wolves don't seem to try to jump fences for food．”可知，筑栅栏是有效的，能够成功阻止狼袭击牲畜，因此是值得推广的方法。故选B。] 单元主题 考点归纳 题型组合练 基础巩固 主题引领 选择性必修第二册　Unit 5　A delicate world √ 4．What is the best title for the text?
