四、阅读理解
It's winter in Siberia in the east of Russia.Lake Baikal is covered with ice.If you want to get to Olkhon Island, more than 27 kilometres out from the shore, you can't take a boat.You have to drive across the ice.But don't worry because the ice is about 60 centimetres thick.Just try not to think about how much water is below you.Try to forget that you're traveling over the deepest lake in the world.
At its deepest, Lake Baikal is about 1,640 metres deep.The lake is more than 630 kilometres long and it is over 25 million years old.On either side of it, there are mountains which are very slowly moving apart—by about 2 centimetres each year.
Around the beginning of the twentieth century, the Trans-Siberian Railway was built, crossing Russia from west to east.Before then, it was difficult to travel across Siberia's long distance,so Lake Baikal was quite an isolated (与世隔绝的) place.Building the railroad along the shore of the lake was a difficult job, but it enabled more people to visit the area.
Olkhon is the largest island in the lake.For the local people, it is a scary place.For them, Lake Baikal is not simply a lake.It is the “father” of 337 “daughters”.These “daughters” are all the rivers and streams around the lake.In a legend, one of the daughters, Angara, ran away from the family.This explains why the Angara River flows out of the lake while her 336 “sisters” flow into it.
Lake Baikal is usually frozen from January to May.When the weather gets warmer and the ice breaks, visitors can take a boat to Olkhon to enjoy the quiet beauty of this place.
1.Why was Lake Baikal an isolated place before the Trans-Siberian Railway was built
A.Because the ice on the lake was too thick to cross.
B.Because there were no boats to take people to Olkhon Island.
C.Because local people didn't allow visitors to come.
D.Because it was difficult to travel across Siberia's long distance.
2.What does the word “enabled” mean
A.Allowed. B.Prevented. C.Reduced. .Recorded.
3.What can we infer from the legend about Baikal and its 337 “daughters”
A.The Angara River is the only river that flows out of Lake Baikal.
B.All rivers around Lake Baikal are called Angara.
C.Local people think Lake Baikal is not important.
D.The 337 “daughters” are all islands in Lake Baikal.
4.Where is this text most likely taken
A.In a chemical textbook.
B.In a travel guide.
C.In a storybook.
D.In a news report.

二、阅读理解
The Yellow River is a precious treasure of China.People living near its banks are always worried about floods(洪水).Now, scientists can solve these flood problems better with a digital (数字的) copy of the river.This helps stop floods from causing harm.
The digital copy uses technologies like big data, AI, and the internet.Tools placed along the river collect information and send it to a control centre.With this information, the system makes a model.Then, a 3D picture on screens shows how the river is doing right now—It's like the river's digital copy.
One great thing of the copy is “smart stones”.They look like real stones, but they are special tools.Workers put them on dikes(堤坝).The stones can feel if the dikes move and send warnings right away.These sensors(传感器) help keep floods from becoming more dangerous.
Above the water, drones (无人机) fly in the sky.Engineers set fixed routes for them.The drones watch the dikes and send new information.They take photos and share reports, so experts can update the 3D model whenever needed.Together with tools under the water, this technology protects the whole Yellow River area.It also makes digital management in the future even better.
1.Why do scientists use a digital copy of the Yellow River
A.To make the Yellow River look more beautiful.
B.To solve flood problems better.
C.To collect stones from the river.
D.To let drones fly more easily.
2.What can “smart stones” do
A.Help workers build more dikes.
B.Collect data for AI.
C.Make sounds to warn people of dangerous situations.
D.Feel if dikes move and send warnings quickly.
3.Which of the following is the best title for the text
A.The History of the Yellow River
B.Digital Tools Helping Protect the Yellow River
C.Different Kinds of Stones by the Yellow River
D.How Drones Work in Daily Life

Recently, Nima Rinji Sherpa from Nepal completed his goal by climbing the 8,027-metre Mount Shishapangma in China's Xizang Autonomous Region.Nima Rinji has become the youngest climber to reach the top of the world's 14 highest mountains.The 14 mountains Nima climbed, known as the “8,000ers”, are each at least 8,000 metres tall.Climbing all 14 is such a difficult and dangerous challenge that only a few people have managed to complete it.
Although Nima comes from a family of climbers, he didn't start climbing seriously until he was 16.He climbed Mount Qomolangma, the world's highest mountain, earlier in 2024.
Nima planned to climb Mount Shishapangma in 2023, but an avalanche (雪崩) at that time killed four people, including his friend and teacher.He stopped his climb and focused on helping other climbers instead.“Climbing is a hard sport.It's about who can suffer the most when times are the worst,” he said.In 2024, Nima returned to Mount Shishapangma, ready to complete his challenge.He said he was thinking of his friend as he reached the top of the mountain.
Nima says he hopes his success will make people know how important Sherpas are to climbing more.Yet, he aims to be more than a guide, saying, “I want to be one of the best climbers in mountaineering.”
