Answer 1

答案：1．C;2．A;3．A;4．C;5．C;
解析：

(1)	由句首的那一句話(huà)可知，導(dǎo)致這種奇怪現(xiàn)象的原因就是因?yàn)闀r(shí)區(qū)的劃分．
(2)	根據(jù)首句，再聯(lián)系地理方面的知識(shí)，可知時(shí)區(qū)與時(shí)區(qū)之間的時(shí)間差為一個(gè)小時(shí)．
(3)	根據(jù)第二段的介紹，自西向東橫渡大西洋時(shí)，因每增加一個(gè)時(shí)區(qū)，就早一個(gè)小時(shí)．即“…traveling east, you set it ahead．”，所以答案為A．
(4)	段首一句說(shuō)得非常清楚，“橫渡大西洋做五天的旅行”，段落末尾又說(shuō)“每一天你的旅行不是二十四小時(shí)，就是二十五小時(shí)”．由此可以判斷大西洋跨五個(gè)時(shí)區(qū)．
(5)	“…this is the point where a new day begins．”是答案的出處． 　　這是一篇涉及地理方面的知識(shí)性小品文．地球上共劃分了二十四個(gè)時(shí)區(qū)，兩個(gè)相鄰的時(shí)區(qū)之間時(shí)間正好相差一個(gè)小時(shí)．因此，我們環(huán)球旅行時(shí)，就會(huì)遇到時(shí)差問(wèn)題．國(guó)際日期變更線(xiàn)是新的一天開(kāi)始的地方．穿越這條線(xiàn)向東去，今天就變成了昨天，向西去，今天就成了明天．
