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.

【解析】文章讲述的是时区的问题。

1.细节题。根据第一段You can have days with more than twenty-four hours and days with fewer than twenty- four hours.可知C正确。

2.细节题。根据第一段第2句The time difference between two zones is one hour.可知B正确。

3.推理题。根据文章第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.本题并没有说明是向西还是向东，可知D正确。

4.推理题。根据文章最后一句话If you travel east, today becomes yesterday, if you travel west it is tomorrow.可知向东，是要延后一天，故5号就变成了4号，B正确。

5.文章讲述的正是世界时区的问题，因为世界被分为不同的时区，进入不同的时区，时间也会随之改变。故A正确。
