The Victoria Falls, known locally as “Mosi-oa-Tunya” （The Smoke That Thunders）, is one of the most spectacular waterfalls in the world. It is located on the Zambezi River, which forms the border between Zambia and Zimbabwe. The falls are about 1.7 kilometres wide and 108 metres high, creating the world's largest sheet of falling water. When the Zambezi River is at its peak flow, the sight and sound of

The nearby national parks are home to a diverse range of wildlife, including elephants, lions, and zebras.

The Amazon Rainforest is the largest rainforest in the world. It covers most of the Amazon Basin in South America. The rainforest is home to millions of different kinds of plants and animals. There are thousands of tree species, many of which are used for medicine. Also, there are many rare animals like jaguars, sloths and colourful birds living there. The Amazon Rainforest is often called “the lungs of the Earth” because it produces about 20% of the world's oxygen.
However, the rainforest is facing many problems now. People cut down trees to make space for farms and cities, which destroys the homes of many animals. Also, the climate change affects the rainforest's ecosystem. Many environmental groups are working hard to protect the Amazon Rainforest.#1

三、阅读理解。
One of the world's most mysterious natural wonders is located in the middle of the Sahara Desert. It is called the “Eye of the Sahara” or more formally, the Richat Structure（理查特结构）.Unlike famous mountains or canyons, this wonder is so huge that it is best seen from space! It has a diameter（直径） of about 50 kilometers, making it one of the largest and most unique geological formations on Earth.
For a long time, scientists were puzzled by its perfect circular shape. They first thought it was a crater（弧坑） made by a meteorite（陨石） impact. However, after further study, they now believe it was formed by the uplifting of rock layers and then worn down by erosion（腐蚀） over millions of years. The different colours and shapes we see are various types of rock layers, creating a beautiful, giant bull's-eye（靶心） in the desert.
Despite its remote location, the Eye of the Sahara attracts adventurous tourists and scientists. It stands as a powerful reminder of our planet's ancient history and the incredible forces of nature that shape our world.#3

B
A.The Eye of the Sahara is a very small and hard-to-find spot.

( )4. What creates the distinctive “bull's-eye” appearance of the structure
A
A.Different types and colors of rock layers exposed by erosion.
B.Rings of trees planted by ancient civilizations.
C.Stains from different minerals in the groundwater.

二、阅读理解。
The deep sea is one of the least explored places on Earth. It starts about 200 metres below the ocean's surface, where sunlight cannot reach. This area is in permanent darkness and is extremely cold.
Despite the harsh conditions, life exists here. Many deep-sea creatures produce their own light through a process called bioluminescence to attract prey or mates. The anglerfish, for example, has a glowing lure on its head to trick smaller fish.
Exploring the deep sea is challenging for humans because of the immense water pressure. Special submarines called submersibles are built with strong materials to withstand the pressure and allow scientists to study this unique environment.
We know more about the surface of the Moon than we do about the deep ocean floor. Scientists believe that there are millions of species in the deep sea that are still unknown to us, making it a true final frontier for discovery.#4
