Each day of your trip has either twenty-five or twenty-three hours.If you travel by ship across the Pacific Ocean (太平洋), you cross the International Date Line (国际日期变更线).

They might also think that teachers write too fast. They are just trying to find ways to make things easier. But so digital cameras or recorders really make taking notes easier? Not really! Before you can read the notes on your digital cameras, there are a lot of things to do. You have to find a computer to download the photos. You also have to find a printer to print the photos out. To listen to the sounds from the digital recorder is even harder. There is usually a lot of noise with what you have recorded.
