Wildfires are a common natural disaster in dry, forested areas. They can start from lightning, human carelessness(like leaving a campfire unattended), or even a broken power line. In 2023, a large wildfire broke out in a national park in Canada. The fire spread rapidly because of the hot, dry weather and strong winds. Local people were warned to evacuate their homes immediately, and firefighters from across the country travelled to help put out the blaze.
After the fire was finally contained, lots of houses had been damaged, and many wild animals lost their habitats. The government supplied food, tents, and medical aid to the affected families. Scientists reported that the wildfire also caused heavy air pollution in nearby cities, leading to health warnings for children and the elderly.
In the months that followed, the community came together to plant new trees and create firebreak—areas cleared of vegetation to stop future fires from spreading. People learned that protecting forests and making emergency preparations, such as keeping a supply of water and a fire escape plan, are essential for staying safe.

解析
1. 原文第一段介绍野火的起因包括闪电、人类疏忽（比如无人看管营火）、破损电线等，A选项“人们的粗心行为”符合原文描述，B选项湿热天气、C选项强风都不是野火的引发原因，因此选A。
2. 原文第一段明确说明2023年加拿大野火快速蔓延的原因是炎热干燥的天气和强风，A海啸、B大雪均未在文中提及，因此选C。
3. 原文第二段提到火灾得到控制后，政府向受影响的家庭提供了食物、帐篷和医疗援助，A为所有人建造新房、B采访受灾家庭均不符合原文内容，因此选C。
4. 原文最后一段用破折号对firebreak作出解释：清理掉植被、用来阻止未来火势蔓延的区域，A灭火工具、B野火预警系统都不符合该定义，因此选C。
5. 原文最后一段提到人们从这场野火中认识到，保护森林、做好灾害应急准备对保障安全至关重要，A野火只发生在澳大利亚、B洪水比野火更危险的表述均未在文中出现，因此选C。
