读世界某地全年日出时刻示意图,回答问题。

小题1:该地的经度是

A.152.5°W

B.150°W

C.92.5°E

D.40°E小题2:T日期过后

A.北京日落时刻推迟

B.全球极夜范围扩大

C.该地正午日影由朝南转为朝北

D.该地正午太阳高度增高

答案

小题1:A

小题2:D

本题考查读图能力、地方时、昼夜长短、正午太阳高度等知识。

小题1:从图中可以看出该地一年的日出时刻在北京时间0点到0:20之间变化,说明日出时刻为北京时间0点或0:20为夏至日或冬至日,日出时刻北京时间0:10为二分,此时当地日出地方时为6点,由此可计算出当地经度。

小题2:直接判断分析,由于该地日出时刻变化不大(20分钟),说明该地昼长年内变化不大,该地的纬度较低(回归线之间,位于北纬20°最大昼长为13小时13分),T时刻为12月22日或6月22日,但此后一定向该地移动,故正午太阳高度变大。

Nobody Benefits

NEW YORK—America has been experiencing the longest economic increase in its history.Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings.

But just a short walk from Manhattan's skyscrapers, George Brown sits on the side-walk, cooking a lunch of rice and bits of fish over a can of cooking fuel.

Brown is homeless — one of the 2.3 million people in the US who end up on the street.

During the day, Brown collects aluminium cans and sells them for five cents a piece.At night, he sleeps on the street.

"I have been on the street about eight or nine years, something like that," said the 62-year-old former construction worker.

Brown admits he's had problems with alcohol and has smoked cocaine.But he said he still wants a more stable housing arrangement.He could afford it just with the money he earns by collecting cans and small pieces of metal, if only truly low-income housing were available.

However, he sees no hope of finding affordable housing in New York.

With the strong economy and unemployment down, beautiful housing is being built to meet demand.

A US report shows rents in New York city rose more than 27 percent between 1984 and 1999, from US $549 to US $700 a month.

One of the side effects of the strong economy is that rents have been going up.

The majority of people who experience homelessness really just need some affordable housing help.

But few housing companies have been built for the poor.Many small apartments in the city now rent for US $1,500 a month or more.

Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her.She is angry about his drinking and won't allow it in her house.

Smiling, he said he also has seven grandchildren whom he'd like to see more often.

"All I've got to do is clean up my act," he said.
