In February 2022, Chen Kaiyin from Beijing paid 2,000 yuan and “adopted（领养）” a panda online at Nanjing Hongshan Forest Zoo in Jiangsu. 【小题1】 Because of some social problems, the number of visitors went down greatly. More than 80 percent of zoos had money problems.

Like Nanjing Hongshan Forest Zoo, many zoos have also faced the same kind of problems. 【小题2】

Beijing Zoo has made ice creams in the shape of elephants, giraffes, pandas and parrots. It also makes soft toys and hats with the image（形象）of tigers. These creative products are popular with children.

【小题4】 Shen Zhijun, head of the Nanjing Hongshan Forest Zoo, said modern zoos should no longer be places for visitors to just see animals. Zoos can teach people how to protect animals.

Shen said, “Our zoo animals are not just for fun. 【小题5】”

A river is a flowing, moving stream of water. Usually a river feeds water into an ocean, lake, pond, or even another river. Rivers can differ in size and there is no strict rule on how big a flow of water must be to be called as a river. Here are the five longest rivers in the world.

	The Nile River The Nile River is 4,135 miles long. It is located in the continent of Africa, mostly in the countries of Egypt and Sudan. It flows north into the Mediterranean Sea.
	The Amazon River The Amazon River is 3,980 miles long. It is located in the continent of South America and flows through several countries including Brazil, Venezuela, Bolivia, and Ecuador. It ends at the Atlantic Ocean.
	The Yangtze River Located in China, the Yangtze River is 3,917 miles long and flows into the East China Sea.
	The Mississippi River and the Missouri River The river system of the Mississippi River and the Missouri River is the longest river system in North America at 3,902 miles. It flows south into the Gulf of Mexico.
	The Yenisei River The Yenisei River starts in Mongolia and flows through Russia to the Kara Sea in the Arctic Ocean. It’s 3,445 miles long.

There are 76 rivers in the world over 1,000 miles long. A lot of people think that rivers always flow south, but 4 of the 10 longest rivers in the world flow north. The United States alone has around 3.5 million miles of rivers. Four of the top 10 longest rivers flow through China at some point.

In many countries around the world, children must start going to school at an early age. Then after some years they become “adults”. An adult may have the right (权利) to do some things, like getting a job, voting (投票), having a family, or driving a car. At the same time, an adult has to take some responsibilities (责任), too.

In many countries, sixteen or eighteen is the age when a person becomes an adult. Young men and women at this age can go out to work and begin to make money. They don’t have to ask their parents for money all the time. In Canada and America, sixteen is the age when one can drive a car. In England, it is seventeen.

There are also responsibilities that follow an adult’s rights. When you get a job, you have to pay income tax (所得税). When you drive a car, you must follow the rules. Voting is another right that young people enjoy when they become adults. In the US, Canada and England, young people have the right to vote at the age of eighteen. But when young people vote, they must know what they really need for their country, and they must also learn how politics (政治) works.
