你(Li Yuan)收到朋友Xiao Ming的e-mail，他在邮件中谈及买车计划。请在回信中说明你对买车的看法，内容包括：私家车的好处（如舒适、便捷等）；私家车的弊端（如交通拥挤、环境污染、停车困难等）；你的建议。
Dear Xiao Ming,It's great to hear that you've got the driver's license and want to buy a car. I'm working on that, too. But I'm lost in hesitation.Driving a car, of course, is convenient and comfortable on working days to go to work and back home and on holidays to travel around with family. However, there, definitely, are many problems, too, heavy traffic, limited and expensive parking lot, for example, especially the pollution to the air which is harmful to human.So, you see, I really don't know what to do. But I do feel an electric car would be a better choice, though the recharge of the battle is not convenient. It won't be a long waiting to improve it, I believe. You may think about that.Take care.
