修改下列对联。（只改动一处）。（2分） 松竹梅岁寒三友，桃李杏春风一家。 ___

（28分）新一届中央领导集体在制度建设上的第一个行动就是进行“营改增”税制改革。阅读下列材料，回答问题。

材料一 表1 中国税收弹性系数变化情况

	“九五”期间	“十五”期间	“十一五”期间
GDP增长率（%）	8.3	9.5	11.2
税收增长率（%）	16.3	19.5	21.8
税收弹性系数	1.37	2.24	1.95

  注 ：税收弹性系数=税收增长率／GDP增长率。若税收增长率小于GDP增长率，即税收弹性系数小于1，则纳税人整体税负减轻。

表2  中国基尼系数变化情况

20世纪80年代	2000年	2005年	2010年
0.21-0.27	0.412	0.485	0.481

  注：基尼系数是反映居民之间收入差距的指标。0.3以下表示比较平均，0.3～0.4表示相对合理，

0.5以上表示收入差距悬殊。

材料二 2012年11月“十八大”提出“2020年实现国内生产总值和城乡居民人均收入比2010年翻一番”，作为未来经济发展的战略目标。有人认为，实现“收入倍增计划”离不开政府“放水养鱼”，切实实施减税政策，提高企业的投资能力和居民的消费能力，为经济的增长释放能量。

（1）描述材料一反映的经济信息。（6分）

（2）结合材料一、二，运用《经济生活》知识，请你为实现收入倍增计划提出合理建议。（12分）

（3）结合材料二，运用《政治生活》知识，分析实现“收入倍增计划”离不开党和政府的原因。（10分）

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the America from being discovered by the people of Europe.

Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to “the edge of the world” . Sailors were afraid that they might sail off the earth. Another idea was that at the equator(赤道) the ocean would be boiling hot.

The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2,00 miles (3,200 km) wide.

Two things make the Atlantic Ocean rather unusual. For so large an ocean it has few islands. Also, it is the world’s saltiest ocean.

There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers, it would take the ocean about more than 4,000 years to dry up. On the average, the water is a little more than two miles (3.2km) deep, but in some places it is much deeper. The deepest spot is near Puerto Rico. This “deep” measures 30,246 feet---almost six miles (9.6km).

One of the longest mountain ranges of the world rises from the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands.

Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels(船) the crew were afraid they would be becalmed (can’t move) here. Sometimes they were.

Today the Atlantic is a great highway. It is, however, not always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the far North across the paths of ships.

We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!
