Question

Time Zones（時(shí)區(qū)）

Strange things happen to time when you travel. Because the earth is divided into twenty-four zones one hour apart（相差）.You can have days with more or fewer than twenty-four hours, and weeks 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. Travelling 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（太平洋）, you cross the international date line. By agreement, this is the point where a new day begins, when you cross the line, you change your calendar one full time day, backward or forward. Travelling east, today becomes yesterday; traveling west, it is tomorrow.

試題分析：

1.這是細(xì)節(jié)理解題。根據(jù)Because the earth is divided into twenty-four zones one hour apart（相差）.一句話可知，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。故選B。

2.這是細(xì)節(jié)理解題。根據(jù)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.段落末尾又說“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)。故選A。

3.這是細(xì)節(jié)理解題。根據(jù)Travelling west ,you set your clock back;故選 D。

4.這是細(xì)節(jié)理解題。根據(jù)this is the point where a new day begins故選 C。

考點(diǎn)：這是一篇知識(shí)性小品文。

點(diǎn)評(píng)：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)差問題。國(guó)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。做這種題需用地理方面的知識(shí)來幫助考生理解。
