Strange things happen to time when you travel because the earth is divided into twenty-four zones（时区）,one hour apart（一个时区相差一个小时）．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（大西洋）,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 it ahead．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）．By agreement,this is the point where a new day begins．When you cross the line,This is the point where a new day begins.When you go across the line,you change your calendar one full day,back or ahead.Isn't it interesting?
