You can have days with more than twenty-four hours and days with fewer than twenty- four hours. You can have weeks with more than seven days and weeks with fewer than seven days.

If you make a five-trip across the Atlantic Ocean , your ship come into a different time zone every day. As you come into each zone, the time changes one hour. If you travel west, you set your watch back. If you travel east, you set it ahead. Each day of your trip has either twenty-five or twenty-three hours.

【解析】文章講述的是時區的問題。

1.細節題。根據第一段You can have days with more than twenty-four hours and days with fewer than twenty- four hours.可知C正確。

2.細節題。根據第一段第2句The time difference between two zones is one hour.可知B正確。

3.推理題。根據文章第2段2,3行As you come into each zone, the time changes one hour. If you travel west, you set your watch back. If you travel east, you set it ahead.本題并沒有說明是向西還是向東，可知D正確。

4.推理題。根據文章最后一句話If you travel east, today becomes yesterday, if you travel west it is tomorrow.可知向東，是要延后一天，故5號就變成了4號，B正確。

5.文章講述的正是世界時區的問題，因為世界被分為不同的時區，進入不同的時區，時間也會隨之改變。故A正確。
