冀教版（一起）一年级英语下册拓展资料Unit 1 My schoolLesson 3 Places in my schoolAbout Time Zone（有关时区） Strange things happen to time when you travel, because the earth is divided into twenty -four zones, one hour separate
You can have days with more or fewer than twenty –four hours, and weeks with more or fewer than seven days
If you make a five-day trip across the Atlantic Ocean, your ship enters a different time zone every day
As you enter each zone, the time changes one hour
Traveling west, you set your clock back; traveling east, you set ahead
Each day of your trip has either twenty-five or twenty- three hours
If you travel by ship across the Pacific, you cross the International Date Line
By agreement this is the point where a new day begins
When you cross the line, you change your calendar (日历)
