题目内容
阅读下列短文，从所给的四个选项中，选出最佳答案
Strange things happen to time now and then when you travel, because the earth is divided into twenty-four time zones (areas) one hour apart (相隔). 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. Travelling west, you set your clock back; travelling 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（太平洋）, you cross the international（国际的）date line. By agreement（协议）, this is the point where a new day begins. When you cross the line, you change your calendar（日历） one full day, backward or forward. Travelling east, today becomes yesterday; travelling west, it is tomorrow!
