     When I stepped out the plane from Miami into Charlotte, North Carolina, airport for a connecting

flight home, I immediately knew something was wrong. Lots of desperate people crowded the terminal.

I quickly learned that flights headed to the Northeast were called off because of a storm. The earliest they could get us out of Charlotte was Tuesday. It was Friday. A gate agent stood on the counter and shouted, "Don't ask us for help! We cannot help you!"

     I joined a crowd that ran from terminal to terminal in search of a flight out. Eventually, I found six

strangers willing to rent a van with me. We drove through the night to Washington, where I took a train

the rest of the way to Providence.

     The real problem, of course, is that incidents like this happen every day, to everyone who flies, more

and more often. It really gets to me, though, because for eight years I was on the other side, as a flight

attendant for Trans-World Airlines (TWA).

     I know the days are gone when attendants could be written up if we did not put the lines napkins

with the TWA logo in the lower right-hand corner of the first-class diners' trays. As are the days when

there were three dinner options on flights from Boston to Los Angeles in economy class. When, once,

stuck on a tarmac(机场停机坪)in Newark for four hours, a planeload of passengers got McDonald's

hamburgers and fries by thoughtfulness of the airline. I have experienced the decline of service along with

the rest of the flying public. But I believe everything will change little by little, because I remember the

days when to fly was to soar (翱翔). The airlines, and their employees, took pride in how their

passengers were treated. And I think the days are sure to come back one day in the near future.

1.Many people crowded the terminal because _______.

A. they were ready to board on the planes    

B. something was wrong with the terminal

C. the flights to the Northeast were canceled  

D. the gate agent wouldn't help the passengers

2. How did the writer get to Providence at last?

A. by air  

B. by van    

C. by train    

D. by underground

3. Which of the following is NOT true according to the passage?

A. Incidents happened to those who fly quite often.

B. The writer used to be a flight attendant for Trans-World Airlines.

C. Even a small mistake might cause complaints from passengers in the past.

D. McDonald's hamburgers and fries were among regular dinner options.  

4. What can be implied from the passage?

A. The writer lived in Charlotte, North Carolina.

B. The writer thought the service was not as good as it used to be.

C. The writer with other passengers waited to be picked up patiently.

D. Passengers would feel proud of how they were treated on the plane.

(1)概括材料反映的古代纪年特点。(2分)结合所学,分析这一特点所反映的历史状况。(6分)

格林尼治时间大事记

1840年前格林尼治时间由英国的格林尼治天文台(1675年建)制定,但其影响力有限,英国各地城镇仍遵守地方时间
1847年英格兰和苏格兰铁路时刻表采用格林尼治时间,以克服计时不同给交通造成的混乱局面
1851年600万游客乘火车到伦敦参观世界博览会,首次体验标准时间体系
1880年格林尼治时间成为全英国唯一的、法定的时间标准
1884年英法美德俄日等25国在华盛顿召开会议,确定经过格林尼治天文台的经线为本初子午线,据此确定格林尼治时间为国际标准时间
(2)阅读上表,对格林尼治时间成为国际标准时间的历史进程划分阶段并说明理由。(4分)分析国际标准时间形成的历史条件。(8分)

材料二  1874年法国传教士在上海徐家汇建立了观测台,19世纪80年代这一观测台利用上海法租界内的信号塔开始报告正午时刻,为外国船只服务。这一时间标准被称为“海岸时”。19世纪末20世纪初,列强控制下的清朝海关采用“海岸时”,使用的是东经120º的时刻。此后“海岸时”逐渐被铁路、航运、邮政、电报等行业采用,并延及京奉等铁路沿线和长江流域。1918年,北洋政府将全国划分为5个时区,1927年将北京时定为标准时。1929年国民政府以南京时为标准时,每天通过电报和广播发布;上海、天津、南京、北平等地的车站、码头、银行、机关及市区街道多设标准钟。与此同时,汽笛、午炮或寺庙的钟声等报时方式仍在使用。中华人民共和国成立后将东八区区时定为北京时间。

(3)依据材料二并结合所学,解读从“海岸时”到北京时间在近现代中国的变化历程。(14分)
