C
No noisy cars, no smoky kitchens, no sad wild animals—sounds nice, right? These aren't just dreams: The Netherlands(荷兰), Mexico, and Ecuador(厄瓜多尔) made them real. Let's see how.
The Netherlands
In the 1970s, Groningen (格罗宁根) faced serious traffic problems because of too many cars in the city centre. The local government took away the motorway and replaced(取代) it with green spaces, areas for walking, paths for cycles and buses. Cars can't park in the market square and enter the city centre.
Today, 61% of trips in the city are done by bicycle. The city centre is full of places for bikes to park and most buildings have bicycle parks. As a result, today Groningen has got the cleanest air of any big Dutch(荷兰的) city.
Mexico
In many countries, people still cook and warm their homes using open fires, which cause health problems because of smoke and gas. The Patsari stove, developed in Mexico, uses less wood and makes indoor air better. It has a chimney(烟囱) that takes smoke outside.
Health studies show that families with this stove get 30% fewer lung infections(感染) and 50% fewer eye infections.
Ecuador
The Bigal River Nature Park, between the Amazon and the Andes, is home to different animals and birds. However, human activity has a negative effect on the wildlife there. Many animals and birds are in danger because the forests are getting smaller and people hunt them. To show people how wonderful the nature park is, the Sumac Muyu Foundation set up camera traps(相机陷阱) in 2014. They take videos of animals and study the changes in their activities. The videos can help stop new building projects in the nature park.
In conclusion, different places around the world are taking creative local actions to solve their own environmental problems.

C ［文章大意］本文是一篇说明文。文章介绍了荷兰格罗宁根、墨西哥、厄瓜多尔三个地区针对各自的环境问题采取的创意解决方案，包括推广绿色出行、改良炉灶、用陷阱相机保护自然公园等，展现了不同地区的环保智慧。
42. B ［解析］细节理解题。根据“The Netherlands”部分的“The local government took away the motorway and replaced(取代) it with green spaces, areas for walking, paths for cycles and buses. Cars can't park in the market square and enter the city centre.”和“Today, 61% of trips in the city are done by bicycle.”可知，格罗宁根用绿色空间取代高速公路、设置步行区与自行车和公交车道、限制车辆进入市中心等方式，鼓励绿色出行，进而解决交通问题。故选 B。
43. C ［解析］细节理解题。根据“Mexico”部分的“The Patsari stove, developed in Mexico, uses less wood and makes indoor air better. It has a chimney(烟囱) that takes smoke outside.”可知，墨西哥研发帕察里炉灶是为了减少木材的使用并改善室内空气。故选 C。
44. B ［解析］词义猜测题。根据下文中的“Many animals and birds are in danger because the forests are getting smaller and people hunt them.”可知，人类活动让很多动物濒临危险，所以对野生动物有负面、糟糕的影响，negative 与 terrible 意思相近。故选 B。
技巧点拨 做词义猜测题时，可通过后文的解释性内容推断词义，如本题中“Many animals and birds are in danger”是对 human activity 影响的说明，由此可推断 negative 表示“负面的；糟糕的”。
45. C ［解析］推理判断题。通读全文可知，本文主要介绍了不同地区的环保解决方案。A 选项“印度每年建50家医院”属于医疗领域；B 选项“法国增加20条城际铁路”属于交通建设；C 选项“中国打造100多个无废城市”属于环保举措，符合本文主题；D 选项“南非给学生发放免费课本”属于教育领域。故选 C。
易错警示 本题易误选 B，城际铁路建设属于交通发展范畴，并非环保举措，需明确本文核心是环保解决方案，只有与环保相关的选项才符合要求。
