基于高考外刊源文设计单元主题作业 环境与自然（学生版+教师版）--2026届高三英语复习专项

基于高考外刊源文设计单元主题作业 ———环境与自然 阅读下列短文，从每题所给A、B、C和D四个选项中，选出最佳答案。 A Every year, many howler monkeys and other wild animals in Costa Rica are dying because of unprotected power lines and transformers. As more luxury homes are built for rich foreigners, more monkeys are dying because they cannot tell the difference between electric wires and natural vines. Costa Rica is known for being one of the most environmentally friendly countries in the world, with almost all of its electricity coming from renewable sources. This reputation, along with its natural beauty, has attracted many people like tech entrepreneurs, investors, and celebrities who have chosen Costa Rica as their escape. However, building homes that meet their needs has come with a high cost to the wildlife that first attracted visitors. The problem is worse because building permits are given without proper studies. A tangled mess of wires and transformers connects these homes and resorts to the power grid. Power outages happen often when howler monkeys cause short circuits while crossing transformers. The problem is especially bad in areas where forests are cut down, leaving the animals no choice but to travel on the wires. A group of animal experts at the University of Costa Rica created rope bridges between treetops to give howler monkeys a safe way to cross in a forest near Playa Hermosa, three hours north. This helped the monkey population double there between 2015 and 2021 and may offer a solution if used in other places. By protecting the natural paths of these animals and ensuring that building projects include safety measures, Costa Rica can continue to be a leader in ecological conservation while also meeting the needs of its growing population. 1.
