Question

閱讀理解 　　Strange things happen to time when you travel because the earth is divided(劃分)into twenty-four zones(時區(qū)), one hour apart(一個時區(qū)相差一個小時)．You can have days with more or fewer than twenty-fours, 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．Traveling west, you set your clock back, traveling 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 Ocean(太平洋), you cross the International Date Line(國際日期變更線)．By agreement, this is the point where a new day begins．When you cross the line, you change your calendar one full day, backward or forward．Traveling east, today becomes yesterday．Traveling west, it is tomorrow． (1) Strange things happen to time when you travel because ________． [　　] A． no day really has twenty-four hours B． no one knows where time zones begin C． the earth is divided into time zones D． in some places one day always has twenty-five hours (2) The difference in time between zones is ________． [　　] A． one hour B． more than seven days C． seven days D． twenty-four hours (3) If you travel across the Atlantic Ocean, going east, you set your clock ________． [　　] A． one hour ahead in each time zone B． one hour ahead for the whole trip C． one full day back for each time zone D． one hour back in each time zone (4) From this passage, it seems true that the Atlantic ________． [　　] A． is in one time zone B． is divided into twenty-four zones C． is divided into five time zone D． is in four time zones (5) The International Date Line is the name for ________． [　　] A． the beginning of any new time zone B． any point where time changes by one hour C． the point where a new day begins D． the end of any new time zone

Answer 1

答案：1．C;2．A;3．A;4．C;5．C;
解析：

(1)	由句首的那一句話可知，導(dǎo)致這種奇怪現(xiàn)象的原因就是因為時區(qū)的劃分．
(2)	根據(jù)首句，再聯(lián)系地理方面的知識，可知時區(qū)與時區(qū)之間的時間差為一個小時．
(3)	根據(jù)第二段的介紹，自西向東橫渡大西洋時，因每增加一個時區(qū)，就早一個小時．即“…traveling east, you set it ahead．”，所以答案為A．
(4)	段首一句說得非常清楚，“橫渡大西洋做五天的旅行”，段落末尾又說“每一天你的旅行不是二十四小時，就是二十五小時”．由此可以判斷大西洋跨五個時區(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性小品文．地球上共劃分了二十四個時區(qū)，兩個相鄰的時區(qū)之間時間正好相差一個小時．因此，我們環(huán)球旅行時，就會遇到時差問題．國際日期變更線是新的一天開始的地方．穿越這條線向東去，今天就變成了昨天，向西去，今天就成了明天．
