【1】C

【2】B

【3】G

【4】F

【5】E

【解析】

人们坐长途飞机会影响到人体的生物钟，让人产生疲劳感，产生时差反应。本文就如何调节时差给读者提供了一些小建议。

【1】C 整体看，文章的结构是总分结构，在第一段文章引出话题，介绍了一些时差的情况，而后面的几段就如何调节时差给出了一些建议，所以在备选项当中C项符合结构。

【2】B 该空所在的段落，就Change your watch...做了详细的阐述，备选项当中的B项就是关于change的总结。

【3】G 该段讲的是要提前到，提前到有它的好处，所以G项就是对这种方式好处的介绍。

【4】F 根据后面的Alcohol can affect your sleep.是在讲述酒对睡眠不好，所以F项符合语境。

【5】E 根据后面讲述在临睡前锻炼会影响睡眠，故前面应该是讲要在合适的时间锻炼，故选E项。
