I want to introduce my hometown Hebei. Welcome to Hebei at weekends! 外刊 · 时文阅读速递 阅读理解 The Grand Canyon in Arizona, the USA is one of earth's most amazing natural wonders. Stretching about 446 kilometres long and over 1,800 metres deep, this huge canyon was formed by the Colorado River over millions of years.Its colourful rock layers show earth’s long history,with some rocks being about 2 billion years old. About 5 million visitors come each year to see the Grand Canyon's wonderful views.The canyon's colours change with sunlight during the day—golden in the morning,deep red at midday, and orange in the evening.Many walk the Bright Angel Trail or fly over the canyon.The South Rim is popular, with great views like Mather Point. The Grand Canyon isn't just rocks—many animals live there too.Visitors might see bald eagles flying, mule deer eating grass,or bighorn sheep climbing on rocks.The Colorado River has special fish like the humpback chub,which is endangered.This shows how the whole environment is connected. In 1919,the Grand Canyon became a national park.Now, park workers help keep it clean and safe by teaching visitors to stay on paths, not to leave trash, and not to disturb animals.Problems like climate change and too many visitors could damage this special place, so protection is very important. The Grand Canyon shows nature's power and beauty. It teaches us about earth's history and why we must protect it.Sustainable (可持续的) tourism keeps it safe for the future.

This is true!New Zealand is one of the few countries where sheep outnumber humans.Up to June, 2024, there had been about 23.6 million sheep and about 5.3 million people.That means there were about 4.5 sheep for each person. In 1982, there were about 22 sheep for each person.At that time,farming sheep for meat and wool was very important to New Zealand's economy(经济). New Zealand is about the size of the UK, but it has far fewer people.This leaves plenty of space for sheep. However, sheep numbers is dropping over the years.Wool prices are falling because many people now use synthetic fibres(合成纤维)instead of wool.Farmers are changing how they use their land and are focusing on things like dairy(乳品的)farming and forestry(林业)to make more money. In 2022, there were fewer than five sheep per person,the lowest number ever. Some farmers worry that New Zealand could lose its wool industry(工业) completely. The government is trying to help by encouraging people to use wool products,but farmers think this might not be enough. Other countries,like Australia,also have more sheep than people.Their sheep numbers are falling too. 三．阅读表达 Guo Qingshan works as a designer in Shanghai.In January, he went back to visit his hometown, Yichang in China.During his trip,he went for a hike in the mountains and took some photos.

It is one of the most amazing places on earth.But why is it called the Dead Sea? Can anything live in it?Can people swim there?Let's find out! The Dead Sea is not really a sea—it's a lake in the Middle East.It is the lowest place on land, about 400 metres below sea level. It is between Israel and Jordan.Hot,dry desert surrounds(包围)the lake. Because the weather is hot,water evaporates (蒸发)quickly.But the lake doesn't get enough new water.So the water level gets lower,and lots of salt is left behind.The Dead Sea is saltier than the ocean! Because it's so salty, fish and other animals can't live there.Only a few bacteria(细菌)can. The salt also forms crystals(晶体)on the shore, making it hard for animals to come close. It's so salty.Why do people go there? Actually,it is really safe for people.You can even go swimming there if you want.Although it's pretty hard to swim, all that salt in the water makes it much easier for people to float. Want to know more about it? Just explore it yourself! ( )21.What can you learn about the Dead Sea from the passage? A.It's near the Middle East. B.It's far from the desert. C.It's 11 kilometres wide.
