The Serengeti Plain

The Serengeti is a vast grassland ecosystem in East Africa, covering about 30,000 square kilometres. It is one of the most famous wildlife areas on Earth.     22     During the day, temperatures can reach 30°C, while nights can be quite cool. The region has a wet season and a dry season, which shape the lives of the animals that live there.

The Serengeti is home to over 70 large mammal species and more than 500 bird species.     23     The most famous is the wildebeest, which travels in huge herds. About 1.5 million wildebeest migrate across the plains every year in search of fresh grass and water. This is the largest animal migration on Earth.

The migration is not just a spectacular sight — it is also a matter of survival.     24     The animals move north to find better grazing lands. Along the way, they must cross rivers full of crocodiles and avoid hungry predators like lions and hyenas.     25     It is a test of strength, courage and endurance.

However, the Serengeti is facing challenges. Climate change is bringing more droughts. Human activities are reducing the animals’ living space.     26   

A．The wildebeest migration is a dangerous journey.

B．The climate here is warm and has two main seasons.

C．Many tourists from around the world come to visit this place.

D．These animals include zebras, giraffes, elephants and lions.

E．Conservation efforts are needed to protect this unique ecosystem.

F．The weather here changes very quickly.

五、任务型阅读

Part 1: Read and Explore

Water is important for all living things on Earth. The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the Earth again. It is a cycle that happens the whole year and is most active (活跃的) from March to June in China. In this article, we will learn about the water cycle and discuss its importance for Earth.

The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming (形成) in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally comes back to the Earth again in different forms like rainwater or snow.

The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water.

Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty.Part 2: Skills Challenge
