1. What makes a city a good one to live in? 是什么让城市宜居?
Oh, a lot of factors, to my mind. The ones I consider the most important for life are affordability, I mean housing expenses, the prices for consumable goods, the price of petrol, utility services, taxes and stuff like that, and accessibility, appearance and amenities, that is the presence of the airport, train and bus stations, good transport links, a number of educational institutions, a wide array of recreational facilities, shopping malls, parks and gardens and, of course, hospitals. I would also add good employment Opportunities and low rates to my priority list, oh, and the climate as well.
2. What can people do to improve the air quality in the city? 为了提高城市的空气质量，人们可以做哪些事?
Well, stop using polluting vehicles, first of all, I mean petrol and diesel cars, and start using battery-driven vehicles or public transport. This will significantly improve air quality levels as well as save some money for car owners. It's also a good idea to ride a bike if there are special cycling lanes in the area or walk around instead of using private cars. One more really vital thing for improving the air quality is greening the city. I mean planting trees, bushes and flowers in the yards, gardens and parks.
