It was reported in May 2024 that the China Wildlife Conservation Association (CWCA,中国野生动物保护协会) will send giant pandas Yun Chuan and Xin Bao to the San Diego Zoo in the United States, which is a symbol of a new 10-year period of international conservation partnership. The CWCA has organized experienced caretakers and doctors to go with the pandas to the US. The zoo is getting ready to provide the pandas with a larger and more comfortable living environment. It has also formed a team with special skills related with panda care, daily nursing, and scientific research.

The cooperation (合作) between the CWCA and the San Diego Zoo dates back to 1996 when Bai Yun and Shi Shi became the first pair of pandas to live in the zoo. Giant pandas Hua Mei, born in 1999, and Mei Sheng, born in 2003, who used to live there, are the result of China-US giant panda research cooperation. Over the past twenty years, the two sides have cooperated and solved many technical problems, including important discoveries in key areas like panda raising.

Since the 1990s, China has cooperated on giant panda conservation with 20 countries. “International cooperation in fields such as disease prevention and control, treatment, and wild training and reintroduction to the wild, has achieved good results. Giant pandas will facilitate communication between peoples and let people around the world know China better,” said Li, the leader of the China Conservation and Research Center for the Giant Panda.

“Scientific and educational outreach (延伸服务) also serves as a key role in international giant panda exchanges, allowing more people to understand giant pandas, which provides very good support for our efforts in protecting wild giant pandas,” Li said.

6 . Though oceans cover about 71 percent of the earth’s surface, there’s still a lot we don’t know about them. Only about 20 percent of the seafloor has been mapped, and the remaining 80 percent is still a secret to us. Some scientists even think that 91 percent of sea animals have yet to be discovered.

So why do we know so little about the deep sea? Well, getting to those depths is very difficult and requires high technology that simply didn’t come into being for most of human history. The first navigable submarine (可驾驶的潜水艇), for example, was built in 1620, and it couldn’t go more than five meters below the surface. In fact, for a long time many scientists didn’t even think that there could be any life at depths greater than 550 meters and didn’t see much need to explore (探索) the deep sea. However, this changed in 1862 when life was discovered as far down as 945 meters below sea level with the help of a digging machine. Ten years later, around 4, 700 species (物种) unknown before from the ocean floor were discovered.

Since then, high technology has been developed to help explore the deep sea, including satellites. But why is deep-sea exploration still so difficult? Well, at greater depths it is freezing (极冷的), everything is completely dark, and the pressure can be over 1, 000 times greater than that on the surface.

Though we have the difficulties, it’s important that we understand the seas. They help control the earth’s temperature and produce half of the oxygen (O₂) in the air. They can also provide us with information about climate change. Our future depends on learning more about our oceans, and it is possible for us to really understand what is ongoing below the surface.

1. Why are some numbers listed in Paragraph 1?

A．To introduce how important oceans are.

B．To discuss why sea animals have yet to be found out.

C．To explain that oceans cover a large area of the earth.

D．To show that we have only a little understanding of oceans.

2. What caused the change of exploration into the deep sea?

A．High technology.	B．Unknown species.
C．A pleasant environment.	D．Valuable information.

3. What does the underlined word “They” in the last paragraph refer to?

A．Sea animals.

B．The seas.

C．The satellites.

D．Many scientists.

4. What can we learn from the text?

A．It is difficult to build a navigable submarine.	B．The seas have a strong influence on our future.
C．The seas have no lives at a depth of 550 meters.	D．It is easier to go into the deep sea than we think.

5. What could be the best title of the text?

A．Hidden Treasures in Deep Sea	B．Unlocked Secrets of Deep Sea
C．Deep-Sea Exploration: Into the Freezing Depths	D．Deep-Sea Exploration: The Past and the Future

Once upon a time, there was a little boy. His parents were poor farmers. They couldn’t pay for a worker, so the boy had to help. He worked hard.

Every day, he had a one-hour rest at sunset (日落). He used that time to climb to the top of a hill. There, he could see a house on another hill. It had golden windows. They were really bright and shone like diamonds (钻石).

One day, the boy’s father said to him, “You worked really hard, so you can take a day off. Try to learn something good.”

The boy thanked his father. Then, he left home and walked to the far hill.

He came to the house and knocked on the door, and a girl answered. He told her about the golden windows. The girl shook her head and said, “Poor farmers like us only have glass windows. Look there! That’s the house with the golden windows.” She pointed at something far away.

When the boy looked, he saw his own house. He then thanked the girl and rushed home.
