As we all know, the Yangtze River is the longest river in China. Today let me introduce another famous river to you — the Yellow River.
The Yellow River is the second longest river in China. The “yellow” in its name is from the mud (泥) and sand. About ninety per cent of the mud and sand in the Yellow River come from the Loess Plateau (黄土高原).
The Yellow River starts from the Qinghai-Xizang Plateau. Its shape is similar to “几”. It runs from west to east through nine provinces and finally runs into the Bohai Sea. It covers an area of about 795,000 square kilometres.
In Chinese history, the Yellow River is the most important birthplace. Ancient Chinese people lived on this land, worked hard and created rich culture. Today, the river is important for farming, factories, and people’s lives. It also plays an important role in Chinese culture. People have created a lot of poems, paintings, and songs about it. The Yellow River is a symbol of China. We call it the “mother river”. We love our mother river!

Have you ever heard of the Dead Sea It’s one of the world’s most amazing places. It isn’t a sea, but a large lake. It lies in the Jordan Valley in the western part of Asia and is famous for being the lowest point on Earth.
The water in the Dead Sea is very salty—almost ten times saltier than regular ocean water. Because of this, fish or plants cannot live in it. That’s why people call it the “Dead” Sea. But don’t let the name scare you! The water is so buoyant (有浮力的) that you can float on it easily. It’s a funny feeling, like lying on an air bed!
Many people visit the Dead Sea every year because of its special mud (泥浆). The mud is rich in minerals and is said to be good for our skin. Visitors often cover themselves in the dark mud and then float in the water. It’s a popular way to relax.
However, the Dead Sea is facing a problem. It is shrinking (缩小)! The water level is going down by about one meter per year. Scientists say we need to bring water from other places to save it. If we don’t take action, this natural wonder might one day disappear.
The Dead Sea teaches us an important lesson: nature is powerful and beautiful, but also weak. We should try our best to protect such wonders for our future.

Mountains are usually not nice places for people to live in, mainly because the weather in mountains is not as good as that in low areas. 1． Few people live in the mountains that are over 2,500 meters high, because it’s difficult for people to breathe. If a mountain is more than 8,000 meters high, for example, Qomolangma, there’s not enough air for people. 2．
However, mountains are important to people. Most water in the rivers is from the snow and rain water of the mountains. Lots of people in the world depend on mountains to get drinking water. Mountains are also rich in minerals (矿产). 3． Many people also go to mountains to spend their holidays during the hot summer, because it's much cooler there.

Located in Africa, the Sahara Desert covers 30 per cent of the whole continent. Known as “the great desert” in Arabic, it is about 9 million square kilometres in size, with a history of over 4.6 million years, making it one of the oldest places in the world.
As the world’s largest hot desert, the Sahara is extremely dry and hot all year round. However, not all deserts are hot. For example, scientists regard Antarctica as a typical cold desert.
Most of the Sahara is rocky land. Besides, it also has grasslands, lakes, mountains and sand seas, which look like endless oceans of sand. When the wind blows, the sand looks like waves.
Life in the Sahara is difficult. Around 2 million people live in this area. They usually move from place to place. There is water in a few parts of the Sahara, and some people live in these places all year round.
Few animals can live in a place with such a dry and hot climate. They must adapt to survive. Camels can live for a long time without water, and can drink over 100 litres of water in just 13 minutes. Fennec foxes have large ears to help their bodies stay cool.
Today, the Sahara is getting even bigger. It is 10 per cent larger than it was a century ago. But why is it growing Some scientists believe that part of the reason is climate change. As temperatures rise, summers in Africa grow hotter and less rain falls. Water bodies get smaller and the ground gets drier and drier. If we do not take effective measures, the desert will keep growing!
1．How old is the Sahara Desert according to the passage

2．Where can some people live all year round in the Sahara

Let’s set off on an exciting journey to discover our country’s four major plateaus (高原).
The Qinghai-Xizang Plateau in southwest China is the largest of the four plateaus. 1． With an average altitude (海拔) of over 4,000 metres, it is the highest plateau in the world and is known as the “roof of the world”. This plateau is the birthplace of many Chinese rivers and has over 1,000 lakes, with Qinghai Lake being the largest saltwater lake.
In the north of China, we can find the Inner Mongolian Plateau. As the second largest plateau, it’s about 700,000 square kilometres. It lies mostly between 1,000 and 1,200 metres above sea level. The plateau is mostly flat (平坦的) and has wide grassland. 2．
The Loess Plateau is the third-largest plateau in our country. It rises between 1,000 and 2,000 metres above sea level. The plateau is covered with the yellowish soil (土壤). 3． Through many studies, some Chinese scientists hold that it was carried by the north wind from the Inner Mongolian Plateau and the Mongolian inland areas over thousands of years.
The Yunnan-Guizhou Plateau is the smallest among the four major plateaus. It mainly spreads over the provinces of Yunnan and Guizhou. The plateau has a great difference in altitude, from 400 to 3,500 metres above sea level, and it goes down from the northwest to the southeast. 4． It has many mountains and valleys (峡谷).

Lin Tao (13, Grade 7)—Be Nature’s Guardians (守护者) 8:35 p.m. 19 Sep.
Nature isn’t just there for us to use—it has its own value (价值). We should protect forests, oceans, and animals for our future. We can build more nature reserves (保护区) and cut down pollution. It’s also important to learn to enjoy nature and live peacefully with it, not just take from it. Small actions like saving water can help a lot if everyone does them.
Wang Mei (14, Grade 8)—Technology Helps the Environment 8:45 p.m. 19 Sep.
We can’t give up modern life and go back to a simple one. Instead, we should use technology to fix environmental problems. For example, we can develop clean energy like solar power to take the place of coal and oil. Technology caused some of these problems, so we need smart ideas and new inventions. Humans can’t live without a good natural environment, so we need smart ideas and new inventions.
Zhang Jian (15, Grade 9)—Balance Protection and Progress 10 minutes ago
We need natural resources to develop, and we have to use them in a proper way. For example, we can cut down trees, but we should also plant new ones.
