Wildfires burning across western Canada have forced thousands of people to evacuate their homes and have prompted some oil and gas companies to curb production as blazes approach pipelines. The fires have burned about 478,000 hectares, or 1,800 square miles, across Alberta and British Columbia as of Monday — 10 times the average area burned for this time of year, according to the NASA Earth Observatory.

在加拿大西部燃烧的野火迫使数千人撤离家园，并迫使一些石油和天然气公司限制生产，因为大火已经开始接近运输管道。根据美国宇航局地球观测站的数据，截至周一，阿尔伯塔省和不列颠哥伦比亚省的大火已经烧毁了47万8000公顷，即1800平方英里，是每年这个时候平均被烧毁面积的10倍。

The smoke also has caused poor air quality and hazy skies in parts of southern Canada, as well as in North Dakota, Minnesota and several other states. The spread of the smoke, which contains particles called aerosols, has prompted concerns over the impact of poor air quality on respiratory and cardiovascular health.

大火的烟雾还导致加拿大南部、北达科他州、明尼苏达州和其他几个州的空气质量变差，天空都是雾蒙蒙的。烟雾中含有被称为气溶胶的颗粒，它的扩散引发了人们对恶劣空气质量对呼吸系统和心血管健康影响的担忧。

例句：Climate change is increasing the frequency and intensity of wildfires in western Canada and prompting longer seasons. Rising temperatures, prolonged periods of drought and shifts in precipitation patterns make the region more vulnerable to fires that ignite and spread quickly.

气候变化正在增加加拿大西部野火的频率和强度，并延长野火的蔓延时间。气温上升、长期干旱和降水模式的变化使该地区更容易受到迅速点燃和蔓延的火灾的影响。
