题目内容

【题目】从3月21日到9月23日，可能出现的现象是( )

A. 地球公转速度最慢→快→慢 B. 北极圈内极昼范围的变化小→大→小

C. 北京正午太阳高度的变化大→小→大 D. 南半球昼长时间短→长→短

【答案】B

【解析】试题分析：根据太阳直射点的移动规律。3月21日至9月23日，有个远日点，公转速度最慢，故速度是快-慢-快，故A不符合题意；春分无极昼极夜现象，此后极昼范围变大，6月22日最大，此后变小，故北极圈内极昼范围的变化是小→大→小，故B正确；北京位于北回归线以北地区，夏至日正午太阳高度一年中最大，故正午太阳高度变应该是小-大-小，故C不符合题意；北半球昼长在此期间为短-长-短，故南半球为长-短-长，故D不符合题意。故选B。

阅读下面短文，从每题所给的A、B、C、D四个选项中，选出最佳答案。

Thanksgiving Day is a special holiday in the United States and Canada. Families and friends gather to eat and give thanks for God’s blessing.

Thanksgiving Day is really a harvest festival. That is why it’s celebrated in late autumn. But the first Thanksgiving Day in America had nothing to do with a good harvest. On December 4, 1619, the Pilgrims from England landed near what is now Charles City, Virginia. They knelt down and thanked God for their safe journey across the Atlantic.

The first Thanksgiving Day in New England did celebrate a rich harvest. The Pilgrims landed at what is now Plymouth, Massachusetts, in 1620. They had a difficult time and the first winter was cruel. Many of the Pilgrims died. But the next year, they had a good harvest. So Governor Bradford declared a three-day feast(盛宴). The Pilgrims invited Indian friends to join them for their special feast. Everyone brought food.

After that, other colonies(殖民地)began to celebrate the day of thanksgiving. But it took years before there was a national Thanksgiving Day. During the Civil War, Sarah Josepha Hale persuaded Abraham Lincoln to do something about it. He proclaimed(宣布)the last Thursday of November, 1863 as the day of thanksgiving. Today, Americans celebrate this happy harvest festival on the fourth Thursday in November. Canadians celebrate Thanksgiving Day in much the same way as their American neighbours do. But Thanksgiving Day in Canada falls on the second Monday in October.

【题目】A

The forces that make Japan one of the world’s most earthquakeprone (有地震倾向的) countries could become part of its longterm energy solution.

Water from deep below the ground at Japan’s tens of thousands of hot springs could be used to produce electricity.

Although Japanese hightech companies are leaders in geothermal (地热的) technology and export it，its use is limited in the nation.

“Japan should no doubt make use of its resources of geothermal energy，” said Yoshiyasu Takefuji，a leading researcher of thermalelectric power production.

The disastrous earthquake and tsunami on March 11,2011 caused a reaction against atomic power，which previously made up 30 percent of Japan’s energy needs，and increased interest in alternative energies，which accounted for only 8 percent.

Artist Yoko Ono has called on Japan to explore its natural energy，following the example of Iceland which uses renewable energy for more than 80 percent of its needs.

For now，geothermal energy makes up less than 1 percent of the energy needs in Japan，which has for decades relied heavily on fossil fuels and atomic power.

The biggest problem to geothermal energy is the high initial cost of the exploration and constructing the factories.Another problem is that Japan’s potentially best sites are already being developed for tourism or are located within national parks where construction is forbidden.

“We can’t even dig 10 cm inside national parks.” said Shigeto Yamada of Fuji Electric，adding that regulations protecting nature would need to be relaxed for geothermal energy to grow.

Researcher Hideaki Matsui said，“Producing electricity using hot springs is a decadeslong project.We also have to think about what to do for now as energy supplies will decline in the short term.”

The Earth Policy Institute in Washington，US，believed Japan could produce 80 000 megawatts (兆瓦) and meet more than half its electricity needs with geothermal technology.

Japanese giants such as Toshiba are already global leaders in geothermal technology，with a 70 percent market share.In 2010，Fuji Electric built the world’s largest geothermal factory in New Zealand.

【1】What would be the best title for the text?

A．Alternative energies in Japan

B．World’s largest geothermal plant

C．Japan takes the lead in geothermal technology

D．Japan thinks of geothermal energy

【2】What percentage of Japan’s energy needs is geothermal energy?

A．About 8%. B．Below 1%.

C．Around 30%. D．Over 80%.

【3】According to Shigeto Yamada，the growth of geothermal power in Japan needs________.

A．a change of rules B．financial support

C．local people’s help D．high technology

【4】It can be learned from the last two paragraphs that________.

A．the world’s biggest geothermal plant was built by America

B．Japan will not export its geothermal technology

C．the potential of Japan’s geothermal energy is great

D．it is hard to find geothermal energy in Japan
