你好，我想咨询关于ec2免费套餐的计费政策

1、从哪里查看我的免费套餐的开始日期，到期前通知吗？过期了12个月是否会自动计费？ 2、ec2的免费12个月实例主机,如果长时间执行高度占用 CPU 的任务，是否会增加费用，或者在CPU占用这块有没有什么限制。 谢谢！

1. Where can I view the start date of my free package and will I be notified before it expires? Will it automatically start charging after 12 months of expiration?
2. For the free 12-month instance host on EC2, will there be any additional charges if it performs high CPU-intensive tasks for a long time? Are there any restrictions on CPU usage? Thank you!
