Mom: Of course. For example (例如), it is 2:45 p.m. now in China, but it is 6:45 a.m. in the UK. Because our country is 8 hours ahead of (提前) than the UK.
Xiaojun: Amazing! Is there any time difference between China and the USA?
Mom: Yes, there is. China is 13 hours ahead of than the USA.
Xiaojun: Oh, it is 1:45 a.m. in the USA!
Mom: That’s right! People in the USA are sleeping now.
